Borrow with Bitcoin

Borrow fiat or stablecoins by using your Bitcoin as collateral, without the need to sell your Bitcoin holdings. Access liquidity while maintaining your Bitcoin investment strategy.

Invest securely

Invest in Bitcoin-backed loans and earn interest on your capital. Your investment is secured by Bitcoin collateral that is always worth more than the loan amount.

Non-custodial protocol

Firefish never touches, trades, or exchanges your Bitcoin collateral. It is securely locked in a smart contract built on top of the Bitcoin network, making the process secure for both borrowers and investors.
