Quovra developer docs

Quovra is a Solana settlement kernel for prediction markets. Escrowed devnet USDC unlocks only after a signed TxLINE match proof is verified on-chain inside the settlement transaction.

Use these docs to integrate, run, verify, and operate Quovra.

What Quovra proves

A market outcome should not depend on a vote, a trusted resolver, or an off-chain script after funds are escrowed.

Quovra links these steps in one verifiable path:

A user deposits devnet USDC into a program-owned vault.
A keeper submits a signed TxLINE stat proof.
The Quovra program CPIs into txoracle.validate_stat.
The program reads the returned boolean on-chain.
The market is marked resolved.
Winners claim from the vault.
