Borrow bitcoin-backed stablecoins & synthetic assets without intermediaries.

Built on Bitcoin

Lock collateral in a smart contract on the Liquid blockchain. Fast deposit via Lightning Network supported.

Blinded oracle

Oracle signs the reference price updates without knowing in advance about the contract or who the parties are.


No intermediaries or custodians: the collateral can be redeemed anytime once the debt is paid back.

How it works

Lock BTC collateral

Anyone can open a new contract at current reference price, after locking L-BTC as collateral in the covenant.

Borrow Fuji USD

The smart contract creates 1 fUSD for each 1.1 USD worth of BTC locked. More collateral decreases risk of liquidation.

Use, trade or long BTC

Borrow fUSD as leverage, use for commerce or trade for other Liquid assets.
