PayFoldYour AI From escrow
to payout
Sprint Team
On Demand
From hackathon escrow to AI address collection and zero-leakage settlement. We plug into your stack to prototype, validate, and launch autonomous prize distribution experiences your winners actually love.
We leverage NEAR Chain Signatures and Aurora EVM to build a truly autonomous escrow protocol — eliminating manual spreadsheets and server keys with decentralized threshold cryptography.
Powered by NEAR Chain Signatures
// 1. Organizer deposits prize to Escrow
contract.announceWinner(hackathonId, email, 0.25 ETH);
// 2. Autonomous Gemini AI verifies recipient
AI_Agent -> "Congratulations! Provide your EVM address."
Winner -> "Payout to 0x71C...397"
// 3. NEAR Threshold MPC co-signs release

});Core Benefits of NEAR in PayFold
Cross-Chain Key Derivation
A single master account (lakshay-payfold.testnet) dynamically derives distinct, isolated EVM vault addresses for every hackathon on Aurora and Sepolia.
Keyless MPC Threshold Signatures
Zero private keys exist on disk. Payout transactions are co-signed across NEAR’s decentralized validator set (v1.signer-prod) eliminating single points of compromise.
Chain Abstraction for Winners
Winners don't need NEAR accounts or gas. The protocol handles cross-chain execution behind the scenes, delivering native ETH directly to the recipient's EVM address.
Autonomous Escrow
Architecture
PayFold marries Google Gemini AI with NEAR Chain Signatures to eliminate manual spreadsheets and give hackathon organizers trustless, non-custodial prize settlement.
Decentralized Threshold Escrow
(NEAR MPC)The on-chain contract (PayFoldEscrow.sol) locks organizer prize pools on Aurora. Only the authorized NEAR MPC threshold signer can release payouts once the winner's identity is validated by AI.
lakshay-payfold.testnetLock prize funds into the escrow smart contract. The autonomous Gemini agent emails the winner to collect their EVM address and releases payout without server private keys.
NEAR Chain Signatures
Live Settlement Playground
Experience decentralized keyless MPC co-signing in real-time. Watch NEAR Protocol's validator threshold network (v1.signer-prod.testnet) securely verify incoming winner emails and execute cross-chain payouts directly to Aurora EVM — with zero server private keys.
