[Debifi ](https://debifi.com)is a non-custodial lending platform where you can borrow against your bitcoin without selling it. Your bitcoin stays secure in a multisig escrow while you get instant liquidity.

Here's how it works, and how to get your first loan.

## How It Works

When you take out a loan, your bitcoin goes into a 3-of-4 multisig escrow. This means no single party controls your collateral—it's locked specifically for your loan and can only be released when you repay or if there's a default.

The Debifi app handles everything: signing transactions, managing the escrow, and coordinating loan repayment. When you repay the loan, you get your bitcoin back.

## Getting Started: 6 Steps

### Step 1: Download the App
![Step 1](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/step1_9b8d036b42.jpg)

Head to debifi.com/app and download the Android app. Create an account with your email, then set up a strong PIN and enable Two-Factor Authentication (2FA).

### Step 2: Back Up Your Seed Phrase
![Step 2](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/step2_7887fe6916.jpg)

Write down your 12-word seed phrase on paper and store it somewhere safe. This is the only way to recover your account if something goes wrong. Don't skip this step.

### Step 3: Link Your Device
![Step 3](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/step3_421191acec.jpg)

Use your 2FA code to link the app to your account. This connects your phone to Debifi's web platform so you can browse loans and manage your account.

### Step 4: Browse Loan Offers

Go to https://debifi.com/offers and check out available loans. You'll see different terms, rates, and amounts from institutional lenders.

### Step 5: Sign the Loan
![Step 5 ](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/step5_da752c65c5.jpeg)

Found a loan you want? Open the app and sign the contract. The app will generate your public keys and set up the multisig escrow for your collateral.

### Step 6: Deposit and Get Paid
![Step 6 ](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/step6_f67afb62af.jpg)
Send your bitcoin to the multisig escrow address. Once the deposit confirms, the lender sends your loan funds to your chosen address. Done.

That's it. Debifi lets you put your bitcoin to work without giving it up. If you've been sitting on bitcoin but need cash, this is one way to have both.

 How to Get Started with Debifi

In 2025 we moved beyond initial tests, released new products, met the Bitcoin community around the world, and continued building tools that let people use Bitcoin without selling it. Below, we recap the key moments that defined 2025 for Debifi and the broader Bitcoin ecosystem.

2025 was an important milestone for Debifi. This year [Debifi exited the beta stage](/blog/en/debifi-exits-beta) and launched officially into full production. Debifi moved from a promising concept to a fully-fledged platform shaping the future of Bitcoin-backed finance.

In 2025, Debifi was recognized by [Zone21.com](https://www.zone21.com/), a crew of Bitcoiners building for other Bitcoiners, as **one of the safest Bitcoin-backed lending platforms in the world**, **ranking second** for security, transparency, and protection of user funds. This confirms that Debifi’s non-custodial, multisig escrow approach keeps Bitcoin safe and fully under user control.

## New partnerships

We are glad to mention the strategic partnership with [Berglinde](https://cryptodaily.co.uk/2025/01/debifi-and-berglinde-join-forces-to-redefine-bitcoin-backed-fiat-lending-with-loans-in-usd-eur-and-chf), a Swiss firm known for combining Bitcoin and traditional finance. Together, we offer fiat loans in USD, EUR, and CHF, opening up more financial options for users who want to access cash without selling their Bitcoin.

Debifi continued improving security for its users. One of those steps is the [partnership with Sygnum to deliver MultiSYG](/blog/en/sygnum-debifi-combine-bitcoin-multi-sig-technology), an innovative Bitcoin-native multi-signature lending solution from a regulated bank, which is expected to launch in early 2026.

## Meeting the Community

This year, Debifi spent more time meeting  partners, borrowers and lenders in person at conferences organized by the Bitcoin community. For us, these events were about conversations, feedback, and learning how Bitcoin is actually being used.

We participated in the following conferences and events:
- Bitcoin Investor Week New York
- Imagine IF Nashville
- Custody and Treasury Summit Nashville
- Plan B El Salvador
- Free Energy Summit Lisbon
- [Plan B Forum Lugano](/blog/en/max-kei-planb-forum-lugano-bitcoin-banking-2025)
- BTC Prague

 Moreover, Debifi was a main [sponsor of the Baltic Honeybadger 2025 edition](/blog/en/debifi-baltic-honeybadger-main-sponsor), showing our support for the part of the community that believes in Bitcoin as sovereign, secure, and non-negotiable.
 
We shared our vision publicly across key global events, contributing to the broader conversation about Bitcoin’s role in finance.

## Product Progress Throughout the Year

This year Debifi has also introduced the [Bitcoin-backed digital cards](/bitcoin-card) that gives users the possibility to get instant liquidity in just a few steps without selling Bitcoin. The card is designed to connect Bitcoin with real-world payments, including [everyday expenses](/blog/en/use-bitcoin-card-in-daily-life) while keeping the same core principles Debifi is built on: security, transparency, and control.

2025 also brought steady improvements and new options on the platform, including:

- [longer-term Bitcoin loans](/blog/en/debifi-24-month-btc-loans) (now up to 24 months!) 
- improved loan management tools
- continued work on usability and transparency

We continuously worked on improving our Debifi app for Android and making it simpler, faster, more convenient, and easier to use.

We also invested heavily in the **Debifi iOS app**. Over the year, it received multiple functional updates and has now become a _fully independent application_, working separately from the website. This means users no longer need a PC or laptop to manage loans — everything can be done directly from an iOS device, anytime and anywhere.

One of the key updates was the [introduction of a **new Dashboard**](/blog/en/dashboard-notifications). It gives lenders a clearer overview of active loans and makes managing their lending easier and more intuitive, all in one place. Borrowers can now clearly see their total borrowed amount, accrued interest, upcoming payments, and the amount of BTC securing each loan. This makes loan management more transparent and helps borrowers stay in control of their positions.

 We also expanded blockchain support. In addition to Tron, Liquid, and Ethereum, Debifi now supports the Solana network — giving users more flexibility when choosing where to operate.
 
In addition to big releases, we spent the year improving Debifi step by step. Over the course of the year, we introduced and improved several key features, including:
- сustom identity verification (KYC) integration
- added support for attachments so borrowers and lenders can upload documents
- unified notifications across web and mobile with push alerts in the app
- reworked Transaction Confirmation UI
- rolled out hardware-only offers
- added TAPSIGNER support on iOS

We have shared more detailed product updates separately, but the goal stayed the same all year: make Bitcoin-backed lending easier to understand and easier to use.

By the end of 2025, Debifi had grown into a stable platform with real users, real volume, and real products.

The focus going forward stays simple: help people **use Bitcoin without selling it**.

Thanks to everyone who used Debifi, gave feedback, or met us in person this year. We’re building this together — step by step.

Debifi in 2025: A year of growth

Bitcoin is more than just a digital asset — for many, it’s a long-term investment. But what if you need money right now? For a trip, a new laptop because your old one died, the newly launched iPhone or everyday expenses? Going to a bank is painful and long waiting process. Borrow from other people could lead to complicated situations at some point. Selling BTC is not always the best choice, especially when the market may be on the rise.

That’s where the [Bitcoin Card](/bitcoin-card) powered by Debifi comes in. It’s a **digital prepaid Visa card** backed by your Bitcoin as collateral. You don’t sell your BTC — you simply use its value to unlock a spending limit.

Let’s see real-life examples of how the card works and how it helps you stay invested while still covering your needs.

## Book your flights and hotels without selling BTC

You’ve found great flight deals or the perfect hotel — but the crypto market looks promising: Selling Bitcoin right now feels like missing out.

With the Bitcoin backed digital prepaid Visa card, you can avoid it. It lets you keep your Bitcoin and still book your trip. Here is how it works:

1. Use your BTC as collateral to receive a spending limit on the card.
2. Pay for flights, hotels, rentals, or tours directly with the card.
3. Repay the balance later when it’s convenient for you.

Your Bitcoin stays under your control, while sticking to your travel plans. You decide when and where to go without selling your crypto.

## Buy tech today and keep your BTC for the future
Need a new laptop, smartphone, monitor, or home office setup?
Large purchases often come at the wrong time — especially when BTC might go up. And you don’t want to miss the next potential move upward.

Debifi offers an easy possibility to buy the things at the moment you need.

The digital prepaid visa card powered by Debifi makes this simple: You just use your BTC as collateral and get an instant spending limit on the card for any tech purchase you want. You pay in-store or online with the card. All this time your Bitcoin stays safely locked in a non-custodial, 2-of-3-multisig escrow — you keep ownership, and Debifi provides the spending limit.

You get the tech you need now without touching your investment.
Moreover, you can repay your loan whenever you want without any fines.

## Spend every day with no need to cash out
Life is full of small but constant expenses: groceries, gas, subscriptions, online shopping, household items, medicines.

You _could_ convert some Bitcoin every time you need cash — but that means selling your assets piece by piece and losing future potential gains.

The [Bitcoin card](/bitcoin-card) is a digital prepaid Visa card. You can add it to your “digital” wallet on the phone and use it to pay for your daily expenses anywhere Visa is accepted.
The card works perfectly for daily use, so you can:
- Pay in grocery stores and retail shops
- Grab coffee on the go
- Easily pay in cafes and restaurants
- Pay for monthly subscriptions (like Netflix, Spotify, etc.)
- Order from Amazon
- Pay for the gym membership etc.

There’s no need to sell or convert your BTC.
 Just use your card like any other payment card — but backed by your BTC.

<hr>

**The most important thing about the digital prepaid Visa card is that you don’t need to sell Bitcoin when you can use it as collateral.**

This is the main advantage of using a digital prepaid Visa card by Debifi: You keep ownership of your Bitcoin. You simply use its value to cover your everyday expenses.

Debifi’s non-custodial, multisig-secured model keeps your BTC under your control while giving you instant access to funds. Check the details here: [Card offers](/offers?payment_method=product)

How to use the Bitcoin card by Debifi in daily life

To ensure your Bitcoin-backed loan stays secure and you avoid the process of forced liquidation, it’s important to understand what does forced liquidation mean, how does liquidation work and to know the steps you can take to prevent it. Here's what you need to know about forced liquidation and how to protect yourself.

## What is forced liquidation?

Forced liquidation happens when your **LTV ratio** (Loan-to-Value ratio) **rises above 90%** and you don’t take action to fix it. This usually occurs when Bitcoin’s price drops, your collateral loses value, and your loan becomes too risky. The Borrower should either increase the amount of collateral or partially repay the debt to keep the LTV ratio at an appropriate level, between 30 and 70%.

Before a forced liquidation starts, the Borrower will get **three margin call notifications**. What is a margin call? A margin call means a note of warning that your collateral value has fallen below the required level according to your contract.

If you don’t respond and your LTV goes higher than 90%, Debifi notifies both the Borrower and the Lender as well as the Authorized Key Holder that the forced liquidation process has started. You can’t take any actions if the forced liquidation process has started.

The contract is then closed, and the collateral is transferred to the Lender.
 
Forced liquidation can also occur **if the Borrower doesn’t repay the loan**. After the contract ends, the Borrower has 24 hours to repay the debt. If they don’t do it, forced liquidation begins and the collateral will be liquidated in favor of the Lender.
The collateral will be liquidated based on the exchange rate of bitcoin to USD at the time of liquidation.
 
## Important things to know about forced liquidation

_**For Lenders:**_

·        Even in forced liquidation, your interest is safe. There is no risk of losing your interest — all loans on Debifi are over-collateralized.

·        After liquidation of the contract, you receive the loan amount + interest in bitcoin. Since it is a volatile asset, lenders choose to monitor bitcoin price closely and hedge their risks by converting the bitcoin into fiat or stablecoins in a timely manner.
 
_**For Borrowers:**_

·        Be aware that forced liquidation includes a 5% liquidation fee. It is calculated from the outstanding debt at the time of liquidation (remaining loan amount + accrued interest).

·        If the collateral amount in the multisig escrow exceeds your outstanding debt, the difference is refunded to you.
 
<h2>How to avoid forced liquidation – our tips</h2>

**1. Choose a low LTV ratio**

Your LTV ratio shows how your loan compares to your collateral value. If BTC price drops then your LTV rises and therefore you may need to add collateral.

At the moment of signing the contract take into consideration:

Higher LTV = higher risk of contract liquidation.

Lower LTV = more protection but also more collateral.
 
**2. Add extra BTC to escrow**

Even if your loan starts at, say, 70% LTV, you can always deposit more collateral to protect yourself.

Adding more BTC to the multisig escrow gives you more time to react if the Bitcoin price goes down.
 
**3. Monitor the Bitcoin price**

If Bitcoin starts falling, log in to the Debifi account and check the current LTV of your contract.

A quick adjustment can fully prevent liquidation.
 
**4. Use a valid email address**

Debifi sends all notifications, including margin calls, to your email.

Make sure you have access to it. Always use a valid email to create an account on Debifi.
 
**5. Repay the debt on time (or earlier)**

Don’t wait until the last minute. You can close your loan early anytime without extra fees.
 
**6. Act immediately when you receive a margin call**

A Margin call means that your LTV ratio is too high.

Fix it by:

·        adding more collateral

·        partially repaying your loan.

Forced Liquidation is easy to avoid when you stay ahead of your LTV ratio.

Monitor your loan, react to notifications, and let your BTC keep working for you — without selling it.

How to avoid Forced Liquidation

BTC Sessions  released a detailed tutorial showing exactly how to use [Debifi ](https://debifi.com/)to get a Bitcoin-backed [loan](https://debifi.com/offers) He walks through every step, from setting up your collateral to repaying the loan and getting your bitcoin back.

The video demonstrates how Debifi lets you borrow against your bitcoin without handing over custody. Every loan is secured by a 3-of-4 multisignature escrow, which means your BTC stays locked on-chain where you can verify it throughout the entire loan period.

## What Makes Debifi Different

Most traditional lending platforms re-lend your collateral or hide it behind unclear custody arrangements. Debifi does the opposite:

* **Non-custodial by design.** Your bitcoin stays in a verifiable multisig where you hold one of the keys.
* **No rehypothecation.** Your collateral cannot be re-used or lent out to anyone else.
* **On-chain transparency.** Every contract, deposit, and repayment is visible and verifiable on the blockchain.
* **Institutional liquidity.** Loans are matched with professional lenders using fully collateralized bitcoin escrows.

## Inside the Tutorial

BTC Sessions covers the complete borrowing process from start to finish:

1. Setting up a Debifi account and securing it with PIN and 2FA
2. Creating a loan contract and verifying the escrow on-chain
3. Receiving USD-denominated stablecoins (Liquid USDT)
4. Making repayments and automatically reclaiming your bitcoin collateral

**"The way Debifi's multisig is structured aligns incentives perfectly. Neither party wants the collateral moved. It's designed for transparency and peace of mind."** - BTC Sessions

How to Get a Bitcoin-Backed Loan with Debifi: Full Walkthrough by BTC Sessions

- First bank globally to seamlessly combine Bitcoin-native multi-signature wallets with bank-grade lending services  
- Partnership with Debifi addresses growing institutional demand for self-sovereign Bitcoin lending solutions as traditional finance’s embrace of Bitcoin collateral accelerates  
- New product is latest Bitcoin@Sygnum initiative to advance regulated Bitcoin products, technology integrations and research

Zurich, 24 October, 8:00 AM CET — **[Sygnum](https://www.sygnum.com)**, a global digital asset banking group, announces its partnership with **Debifi**, a Bitcoin-backed non-custodial lending platform, to develop **MultiSYG**, an innovative Bitcoin-native multi-signature lending solution. The product, set to launch in H1 2026, is the first multi-signature Bitcoin lending solution from a regulated bank. MultiSYG empowers borrowers to maintain shared control of their collateral through distributed key management rather than via a single custodian. At the same time, they also benefit from the competitive rates, flexible drawdown schedule, loan durations – and white-glove service – of a regulated bank.  

MultiSYG enables Sygnum clients to draw fiat loans against their Bitcoin collateral held in a 3-out-of-5 multi-signature escrow wallet. Distributed control requires multiple private keys to authorise transactions, enabling Bitcoin holders to maintain visibility of their collateral on-chain. This is in line with the fundamental principle of "not your keys, not your coins" that resonates strongly within the Bitcoin community.  

> "A Bitcoin loan should not require blind trust in a custodian," says **Max Kei**, CEO and Founder of Debifi. "MultiSYG's 3-out-of-5 key structure means borrowers can verify their collateral on-chain, while continuing to benefit from Sygnum’s banking relationship and service. After facilitating millions in non-custodial loans, we know this is what the market has been waiting for."  

> “With MultiSYG, we are bringing Bitcoin-native technology to regulated bank lending" says **Pascal Eberle**, Bitcoin@Sygnum and MultiSYG initiative lead at Sygnum Bank. "Borrowers can benefit from bank-grade terms in pricing, drawdown flexibility, and loan duration, while keeping cryptographic proof of their holdings and partial control of their Bitcoin via multi-signature technology. MultiSYG combines the best of both worlds—the ability to hold your own keys while accessing regulated banking products and white-glove service.”  

While other banks require full custody for Bitcoin-backed loans, MultiSYG's distributed key management means clients retain verifiable control of their collateral throughout the loan term – a growing demand from Bitcoin investors. MultiSYG provides a cryptographic guarantee that assets are not rehypothecated, a practice common at traditional banks and other lending services providers.  

This positions Sygnum as the only regulated bank globally offering Bitcoin lending that aligns with the self-sovereignty principles driving institutional Bitcoin adoption. This is a critical differentiator as more companies add Bitcoin to their balance sheets. MultiSYG will complement Sygnum's existing Credit & Lending portfolio and will be available to all Sygnum Bank customers, irrespective of the client’s jurisdiction, upon launch in H1 2026.

Sygnum and Debifi Combine Bitcoin Multi-Sig Technology with Regulated Bank Lending Services

Debifi CEO Max Kei will speak at [PlanB Forum in Lugano](https://planb.lugano.ch/planb-forum/) on October 24-25, joining Pascal Eberle from [Sygnum Bank](https://www.sygnum.com) for "Building 21st Century Banking: Better, Bolder, Bitcoin" at 5:30 PM on the 24th. The panel asks a question Kei has spent seven years answering in code: what does banking look like when you start with Bitcoin's security model instead of retrofitting it onto legacy finance?

## From Private Banking to Bitcoin Infrastructure

Kei's path gives him a particular lens on this conversation. After ten years managing client assets in traditional finance, he left banking in late 2015 after a client demonstrated a $15,000 cross-border bitcoin transaction that took seconds. What seemed insane initially became obvious after research—Bitcoin wasn't just different money, it was different infrastructure.

By 2017, Kei was building in the Bitcoin space. He's since survived multiple bear markets while developing noncustodial peer-to-peer bitcoin-backed lending infrastructure, earning endorsements from Preston Pysh (now a Strategic Advisor to Debifi) and cypherpunk Adam Back. When financial institutions started seeking bitcoin-backed lending solutions, Kei recognized they needed purpose-built infrastructure. Debifi launched in March 2024 as that solution.

## Why 3-of-4 Multisig Changes the Security Model

Debifi's core differentiator is its 3-of-4 multisig setup. Most platforms use 2-of-3 multisig: borrower, lender, and platform each hold one key, requiring two signatures to move bitcoin. Debifi adds a fourth key held by an independent institution. Three signatures are still required for any transaction, but now an attacker would need to compromise three separate entities instead of two.

The borrower's key lives on their mobile device—Debifi supports hardware wallets. The lender holds their key. Debifi and the independent institution hold the remaining two. No single party can move the bitcoin unilaterally.

## Why Noncustodial Architecture Matters

The collateral stays in a multisig escrow address throughout the loan lifecycle—verifiable on-chain, enforced by Bitcoin's scripting capabilities, not by legal agreements or trust. Kei's team surveyed 300 bitcoiners: custodial loans at 8% or noncustodial at 11-12%? 91% chose noncustodial despite higher rates.

That preference reflects learned experience. BlockFi, Celsius, and Voyager all filed for bankruptcy in 2022, locking up billions in customer bitcoin. Debifi's architecture makes those failure modes impossible—not because the team is more trustworthy, but because the bitcoin never leaves cryptographic control. The security model doesn't depend on Debifi being honest. It depends on three-of-four signatures and Bitcoin's native scripting.

## Building Infrastructure for Institutional Bitcoin Lending

Kei now believes banks won't disappear in a Bitcoin future—they'll become infrastructure providers. Debifi operates as exactly that: infrastructure connecting lenders with borrowers seeking bitcoin-backed loans while maintaining noncustodial security.

The platform handles key management, dispute resolution, and loan coordination while keeping bitcoin under cryptographic control rather than custodial control.

## The Question for Lugano

The "Building 21st Century Banking" panel happens at **5:30 PM on October 24th at PlanB Forum**—fitting location given Lugano's positioning as Europe's Bitcoin hub through the Plan B initiative. Kei will be discussing infrastructure his team has built and battle-tested through bear markets. Debifi's noncustodial model proves institutional bitcoin lending works without custodial risk. The industry's choice: build on Bitcoin's security guarantees or repeat 2022's failures.

Max Kei Speaking at PlanB Forum Lugano


Most[ Bitcoin lending ](https://debifi.com)platforms will tell you they're "non-custodial." Then you read the fine print and discover your coins are pooled in some shared wallet, accessible whenever the company feels like moving things around.  

That's not how we built Debifi.  

Every loan on our platform gets its own dedicated multisig escrow. Your Bitcoin doesn't sit in a pool - it's locked in a unique address that requires multiple independent signatures to move. Not just ours. Not just yours. Multiple parties, with the rules enforced at the protocol level.  

Here's exactly how it works.  

## One Contract, One Escrow Address. Always.

<p align="center">
  <img src="https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/One_Contract_One_Escrow_Address_Always_40c90f642b.png" alt="One Contract, One Escrow Address. Always." width="700"/>
</p>

When you initiate the loan, we generate a P2SH multisignature Bitcoin address specifically for that contract by using 4 different public keys. Think of it as a vault that needs three out of four keys to open.  

**Who holds those keys?**
- You (the borrower)  
- Your lender  
- Debifi (for arbitration only)  
- An independent Authorized Key Holder (the failsafe)  

You deposit Bitcoin directly to that address. Once two on-chain confirmations come through - roughly 20 minutes - your collateral locks in for the full loan term. That's it.  

Here's the critical part: nobody can touch those funds alone. You can't. We can't. Nobody can. Any transaction from that address needs three signatures out of four.  
That's not a policy - it's cryptographically enforced by Bitcoin's script.  

We don't hold your funds. Never have, never will. We keep one key solely for arbitration, and that key is useless without two others agreeing to sign. Your Bitcoin stays verifiable and auditable on-chain, controlled by independent parties who each have their own interests to protect.  

## Why 3-of-4 Instead of 2-of-2?

Good question. A 2-of-2 multisig sounds secure until someone loses their key or disappears. Now you've got funds locked forever with no recovery path.  

A 2-of-3 setup is better, but if the platform holds one key, you're back to trusting them not to collude with one other party. Not great.  

Our 3-of-4 structure solves this. Even if one keyholder vanishes - lost phone, forgotten password, goes off-grid for months - the remaining three can still execute the contract according to protocol rules. You get redundancy without creating a single point of control.  

That fourth key, held by an independent Authorized Key Holder, handles specific scenarios: dispute resolution or contractually triggered liquidations. It's not a backdoor. It's a tiebreaker that keeps the system functional without giving any single entity unilateral power.  

Explicit participants. Explicit thresholds. Verifiable outcomes. That's what trust-minimized lending looks like.  

## No Rehypothecation. Ever.

<p align="center">
  <img src="https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/No_Rehypothecation_76b7274e66.png" alt="No Rehypothecation" width="700"/>

Let's be direct: some platforms take your collateral and quietly lend it out again. They call it "capital efficiency." We call it rehypothecation, and we don't do it.  

Your Bitcoin stays in its unique on-chain escrow until the loan's fully repaid. There's no pooling. No reinvestment. No creative reuse of collateral.  

The lender only transfers funds after they've confirmed your collateral is locked in the multisig. Everything's transparent and observable on the blockchain - no intermediaries skimming value or playing games with your coins behind the scenes.  

## Transparency You Can Actually Verify

</p>

We design for verification, not blind trust. Here's how:  

- **On-chain visibility:** Every contract has its own multisig address. You can track your collateral on any block explorer, anytime. If it's moving, you'll see three signatures on-chain authorizing it.  
- **Two confirmations required:** We don't advance the contract workflow until your deposit has two blockchain confirmations. That's roughly 20 minutes, ensuring transaction finality before anything happens.  
- **Client-side key control:** You generate and store your keys using the Debifi Mobile App on a separate linked device. Your keys never touch our servers. Each signing request requires PIN authentication, 2FA, and device verification - so even if someone compromises your dashboard account, they can't sign transactions without physical access to your device.  
- **Hardware wallet support:** We support hardware wallets that give users full control over key generation and storage.  
- **Open-source code:** We're releasing the Debifi App under an open-source license. Anyone can inspect, verify, and audit our security model. Don't trust us - verify the code yourself.  
- **Real-time alerts:** Margin calls, LTV updates, and liquidation warnings hit your dashboard, mobile app, and email instantly. You're never flying blind.  

This isn't security theater. It's an auditable system where you can verify every claim we make.  

## What Happens When Markets Go Haywire?

Security isn't just about custody - it's about how the system behaves when Bitcoin drops 20% in a day.  

Our risk engine follows predictable, rule-based responses. No discretion, no exceptions:  

- **Over-collateralization from day one:** All loans start over-collateralized, so you've got breathing room when markets swing.  
- **Three-tier margin call ladder:** We send alerts at 75%, 80%, and 85% LTV. That's three chances to add collateral, partially or fully repay your loan without any fees, before anything drastic happens.  
- **Automatic liquidation at 90% LTV:** If your position hits 90%, the contract automatically triggers Forced Liquidation. Your collateral gets liquidated according to the terms you agreed to, and any remaining Bitcoin comes back to you.  
- **24-hour grace period at maturity:** If you don't repay on time, you get a 24-hour window before automatic settlement kicks in. This prevents collateral from being liquidated because you missed a notification.  
- **Bounded arbitration:** In rare disputes, our resolution protocol - executed with the Authorized Key Holder - ensures fairness without compromising the multisig structure. Nobody, including us, can override the 3-of-4 quorum requirement.  

Even under extreme conditions, your Bitcoin stays locked, auditable, and recoverable within a transparent, rule-based framework. No black boxes. No surprises.  

## The Bottom Line

**SECURITY ISN'T A FEATURE WE BOLTED ON - IT'S THE FOUNDATION OF EVERY TRANSACTION ON DEBIFI.**  

Your Bitcoin stays in non-custodial multisig escrow. Movement requires consensus from independent parties. Collateral never gets rehypothecated. Everything's verifiable on-chain.  

If you're tired of platforms that ask you to trust them, this is the alternative: cryptographic guarantees enforced by Bitcoin itself.

Your Bitcoin, Your Keys, Your Rules: How Debifi's Multisig Actually Works

Two new features are now live for verified [Debifi](https://debifi.com) users — the **Account Dashboard** and the **Email Notifications System**.  
Both deliver sharper oversight, stronger security, and greater confidence in every transaction.

### Account Dashboard
![Account Dashboard](https://zr5pqljgeynt.compat.objectstorage.eu-zurich-1.oraclecloud.com/blog-production-mainnet/image_4_85ac53a7eb.png)

The new dashboard brings all your lending and borrowing data into one clear, time-selectable view.  
Borrowers can now see their **total borrowed amount**, **interest accrued**, **next payment**, and **BTC collateral** securing each loan.  
Lenders gain instant visibility into their **total loaned funds**, **expected earnings**, and **collateral value** protecting active offers.

Dashboard panels update in real time and cover **active contracts and offers**, **APR and term ranges**, **LTV ratios**, and **payment methods in use**.  
Collateral statistics convert locked BTC into USD and display **average portfolio LTV** and **average BTC liquidation rate**, allowing precise tracking of portfolio performance and margin conditions.  

The **historical performance** section consolidates lifetime activity — **total volume borrowed or lent**, **interest paid or earned**, **average APR and term**, **contract outcomes**, and **payment distribution**.  
It provides a transparent, data-driven record of your Bitcoin-backed operations on Debifi.

### Email Notifications System

Alongside the dashboard, users now receive automatic email alerts for important account and transaction events.  
Notifications are sent when an **origination fee**, **release**, **refund**, or **liquidation transaction** requires signing; when a **repayment**, **release**, or **refund address** is provided or changed; if your **email address** or **2FA seed** has been changed; when a **login from an unusual IP** is detected; or when your **IP allowlist** has been set, unset, or updated.  

Each message includes concise context and a direct link to review or sign, keeping you informed and in control at all times.

These updates reinforce Debifi’s Bitcoin-first principles: transparency, security, and user sovereignty over collateral and capital.

**Log in to your account to explore the new dashboard and review your notification settings.**

BlackRock’s spot Bitcoin ETF surges into the nation’s AUM elite as October inflows accelerate and BTC pushes toward $120,000.  

---

## Why This Matters Now
On **October 2, 2025**, BlackRock’s iShares Bitcoin Trust ([IBIT](https://www.blackrock.com/us/individual/products/333011/ishares-bitcoin-trust)) joined the ranks of the **20 largest U.S. exchange-traded funds by assets under management (AUM)**—an echelon historically dominated by equity and bond exposures.  

That day, **U.S. spot Bitcoin ETFs recorded ~$675.8M in net inflows**, their strongest daily haul since early September. IBIT alone drew **$405.5M**, its biggest single-day intake since mid-August, while **Bitcoin traded around $119K–$120K**.  

For institutional allocators, this signals more than a leaderboard milestone: it confirms that **Bitcoin, wrapped in a regulated ETF, is now a serious portfolio building block**.  
(Source: [CoinDesk](https://www.coindesk.com/markets/2025/10/02/blackrock-s-ibit-enters-top-20-etfs-by-assets-sees-biggest-inflow-since-mid-august))

---

## The Milestone
- **IBIT AUM:** ~$90.7 billion  
- **Status:** Top-20 U.S. ETF by assets  
- **Peers:** SPY, VOO, IVV (S&P 500 trackers), AGG/BND (core bonds), GLD (gold)  

This means a **single-asset, physically backed Bitcoin fund** now sits alongside traditional equity and bond giants in the portfolios of **pensions, banks, and wealth managers**.  

For comparison, **SPDR Gold Shares (GLD)**, the benchmark gold ETF, took over five years to cross $50B in assets after launch. IBIT reached top-20 status in less than two years since its **January 2024 listing**.  

---

## The Flows Driving Adoption
- **October 2, 2025 ETF inflows:**  
  - IBIT: $405.5M  
  - Fidelity Wise Origin (FBTC): $179M  
  - Bitwise: $59M  
  - ARK: $6M  

This institutional cadence follows a pattern: **capital waits through volatility, then moves aggressively when Bitcoin momentum and macro conditions align.**  

Historically, Q4 is Bitcoin’s strongest season, and allocators increasingly prefer ETFs over private custody to gain exposure.  

---

## Bitcoin’s Price Impact
ETF flows are creating a **reinforcing loop**:  
- Creations drive **spot buying**.  
- **Futures open interest** (>$32B) supports hedging.  
- **In-kind creations** (newly approved by the [SEC](https://www.sec.gov/newsroom/press-releases/2025-101-sec-permits-kind-creations-redemptions-crypto-etps) cut costs and slippage.  
- IBIT options volume now **rivals Deribit**, making hedging more accessible for institutions.  

The result: **tighter spreads, reduced slippage, and more predictable liquidity for allocators**.  

---

## Institutional Implications
- **Ranking power:** Top-20 ETFs attract automatic **shelf space, model portfolio inclusion, and analyst coverage**.  
- **Operational readiness:** Many pensions and endowments unlock Bitcoin allocations once funds hit size thresholds.  
- **Diversification case:** Bitcoin’s **low correlation with equities** makes it a potential diversifier, especially when **real yields fall**.  
- **Collateral use:** IBIT shares, cleared and settled on exchanges, are evolving into **programmable collateral**, similar to Treasuries or equities.  

---

## Legacy Comparisons: Gold vs Bitcoin
- **GLD (2004):** Transformed access to gold, hitting $1B AUM in 3 days but taking years to scale.  
- **IBIT (2024–2025):** Surpassed **$90B in less than 24 months**.  

Where GLD legitimized gold as a portfolio asset, **IBIT legitimizes Bitcoin in record time**.  

---

## Policy and Market Structure
- **SEC approval** for in-kind creations reduces tax and trading frictions.  
- **Listed options approval** provides institutional hedging tools.  
- **Fed policy shifts** (potential October 2025 rate cuts) create macro tailwinds for **scarcity-driven assets** like Bitcoin.  
(Source: [Federal Reserve FOMC](https://www.federalreserve.gov/newsevents/pressreleases/monetary20250917a.htm))

---

## Forward Outlook
Three key signposts:  
1. **Top-10 ETFs**: IBIT is ~$50B away—possible within 2 years if momentum continues.  
2. **Collective footprint**: U.S. Bitcoin ETFs now exceed **$150B AUM** combined.  
3. **Competitive landscape**: Fidelity (FBTC) and Bitwise remain strong challengers, but **BlackRock’s distribution dominance** is unmatched.  

---

## The Bottom Line
IBIT’s arrival in the **U.S. ETF top-20** is **not a one-off anomaly**.  
It’s a **structural signal**:  
- **Bitcoin has crossed into the institutional mainstream.**  
- **ETF mechanics are now efficient, liquid, and scalable.**  
- **Allocators no longer need private keys or custody solutions—just a ticker.**  

BlackRock’s IBIT isn’t just a gateway—it’s proof that **Bitcoin is now institutional finance’s newest building block**.
