We’ll walk you through the platform in person, from features to mechanics.
Let’s talk multisig
We will be in Lugano for 2 days, and we came with one subject.
After last year’s hacks, bitcoiners talk about security more than ever. With one key, one mistake is enough to lose everything.
Multisig does not remove all risk. It removes the single point of failure. No party can move the coins alone, and no party can lock them either.
We use it in all our products: loans, liquidity, Vault and the API.
Why people borrow against bitcoin
You need cash for a big expense, but you want to keep your bitcoin.
If you mineNew rigs cost fiat. Borrow for them, keep your bitcoin.
If your company holds bitcoinPay salaries and suppliers. Your company keeps its bitcoin.
If it is for youA car, a kitchen, something you wanted for a long time. You keep your bitcoin.
A borrower story

Right now, we’re preparing the 500,000 m² piece of land for our community… and all of this would not be possible without Debifi.

DebifiSygnum
A Swiss bank now lends against bitcoin in multisig.
The multisig runs on Debifi.
Sygnum already lent against crypto. Now its clients can borrow with bitcoin held in multisig, and hold a key themselves. Sygnum keeps the client and the terms. Debifi runs everything that touches the bitcoin.
Debifi is Sygnum’s strategic partner for bitcoin lending in multisig.

Four products. One idea.
Loans, liquidity, Vault and the API. Each one uses a different number of keys. In all of them, nobody can move the bitcoin alone.
What multisig actually is
An address with more than one key on it. To move a single satoshi, several of those keys have to sign the same transaction. The rules are written in the script and the network enforces them. No company in the middle.
Three of the four must sign. Two signatures are not enough.
2+Several keysSeparate keys, separate signatures. One key signing twice is still one key.
3‑of‑4Your quorumLoans on Debifi use 3‑of‑4, Vault uses 2‑of‑3. Through the API, you choose your own.
On chainVerifiableThe address and its spending rules are public. Do not trust it, check it.
