Bitcoin SPV inside a Soroban contract, in one picture. The contract does not call a Bitcoin node. The caller brings 6 headers, a Merkle proof, and the raw transaction. The contract checks the math.

The relayer is public on testnet: api.testnet.writz.xyz Give it a txid. It returns the headers and the proof shaped for the call. Docs: docs.writz.xyz

Your Bitcoin never leaves Bitcoin. Your loan, nobody sees. Real BTC collateral, verified on-chain via SPV. Zero custodians. ZK-private positions. Your keys. Your coins. Your loans.

Writz Protocol lets you lock real BTC from a Bitcoin wallet and borrow USDC on Stellar. No bridge. No custodian. No wrapped token. A short thread on what that means, what we have already shipped, and where to read the code.

What you can open today: Site and testnet app: writz.xyz Docs: docs.writz.xyz Code (Apache-2.0): github.com/WritzProtocol/wri… Testnet. Not mainnet. We will say mainnet when mainnet is true.

We will post here the way we build: in public, technically, without a launch every week. If you hold BTC and have never used it as collateral without handing it to someone, this is for you. Questions in the replies. We read them.

This is where it started 5 July 2026. One video. No protocol account. The first time Writz existed on X. Everything since then has been making that post true.
