What we built

OPN ShieldEscrow is a privacy-preserving escrow protocol designed for prediction markets on the OPN Chain. It utilizes a secure commit-reveal cryptographic architecture to decouple user identities and wallet addresses from active market participation, while ensuring decentralized and transparent on-chain settlement.

Why

Traditional prediction markets expose critical user behavior, including transaction history, position sizes, and payout destinations directly on-chain. ShieldEscrow resolves these privacy challenges by introducing hidden cryptographic commitments. Built to leverage OPN Chain’s sub-second finality and low transaction fees, it offers enhanced security and superior UX for open finance applications.

How it works

  • Step 1 (Commitment): Users generate a private secret phrase locally, which is cryptographically hashed using keccak256.
  • Step 2 (Deposit): The hashed commitment is sent on-chain, and collateral is locked securely within the Escrow Vault.
  • Step 3 (Resolution): Once the market state updates, users reveal their original secret to verify ownership and safely claim rewards.
