Earn solid returns while helping Bitcoiners keep their coins
Each post lists currency (EUR / CZK / USDC), tenor (3-18 months for P2P, up to 5 years for Prime), and the interest rate the borrower is willing to pay.
As soon as you click Invest, the borrower must lock twice the loan value in a 2-of-3 multisig escrow on-chain before your money leaves your account.
The contract is monitored by oracles; the dashboard shows collateral ratio, accrued interest and the exact liquidation price 24/7.
On maturity the borrower repays you principal + interest. If they don't, their BTC is liquidated and you receive either cash or bitcoin.
Metric | Value |
---|---|
Collateral ratio | 200% (Loan-to-value ≤ 50%) |
Liquidation trigger | 95% LTV, with optional top-ups before that |
Typical yields | 6 – 13% p.a. on P2P deals |
Ticket size | from €1,000 (individual) up to multi-million Prime mandates |
Custody model | Non-custodial 2-of-3 multisig; Firefish holds zero customer BTC |
Every euro you lend is backed by at least two euros' worth of bitcoin, an asset that can be sold 24/7 anywhere in the world.
Funds sit in escrow; even if Firefish vanished, recovery transactions are already in the contract.
Rates are set by open order-book, not by a black-box "yield" desk.
You never handle BTC unless you choose self-liquidation; ideal for investors who simply want predictable cash flow.
You fund €10,000 at 10% p.a.
Borrower posts €20,000 worth of BTC at signing.
Six months later BTC crashes 40%. LTV rises to 83%; borrower tops-up collateral.
At month 12 you receive €11,000 back. If they had failed to repay, escrow would have liquidated just enough BTC to cover your €11,000, and any excess would return to the borrower.
Complete quick KYC and link your bank account.
Set up a Watchdog to be emailed whenever a loan matches your target rate & tenor.
Diversify across several small tickets or allocate larger sums through Firefish Prime for concierge service and automated roll-overs.
Not investment advice. Lending involves risk, including borrower default and bitcoin price volatility. Review the Firefish docs before committing funds.
