Writz Protocol

Bitcoin was built to be yours. Your loans should be too.

Writz is the first trustless Bitcoin lending protocol on Stellar. Bitcoin collateral is locked directly on the Bitcoin network by a Bitcoin Script, verified on Stellar through a Bitcoin SPV client running inside a Soroban smart contract, and every position is kept private through zero-knowledge proofs. There is no bridge, no custodian, and no wrapped token standing between a user and their Bitcoin.

What makes this different

Every other option for putting Bitcoin to work in DeFi asks for one of two concessions: hand your BTC to a custodian, or accept that your loan, your collateral, and your liquidation threshold are public information. Writz removes both. The Bitcoin stays on Bitcoin, secured by Bitcoin Script and accessible only to the depositing user. The loan happens on Stellar, where native USDC and zero-knowledge proof infrastructure already exist. The position stays private, verified by math, not by trust in an operator.
