I built Palindrome Pay – a non-custodial crypto escrow service using 2-of-3 multisig smart contracts. The contracts are open source.I cam to the idea because I got scammed several times and that's a problem. Many crypto projects copy each other, but in my opinion, they lack ideas for adoption and security. I think a crypto payment with escrow for individuals and businesses is the right way to go.

The problem: Real estate developers in Dubai, Oman and other crypto-friendly markets are getting inbound from buyers who want to pay in USDT/USDC. But there's no trustless way to escrow crypto during the due diligence period. Traditional escrow agents don't touch crypto. Existing crypto escrow services are custodial.

How it works: - Buyer deposits USDT into a multisig escrow contract - Funds are locked and visible on-chain during title search, inspections, etc. - Buyer releases funds when conditions are met - If there's a dispute, a pre-agreed arbiter (lawyer, third party) reviews – but the arbiter never has direct fund access, only dispute resolution rights - If no arbiter is set, only mutual cancellation is possible

Tech: Solidity smart contracts on Base/Ethereum/BSC (any EVM chain). Non-custodial – we never hold funds. 1% platform fee. Gas-only on the contract level.

The contracts fit into existing legal workflows: lawyers, title companies and land registries still do their thing in fiat. The escrow just locks the crypto side until closing conditions are met. On-chain audit trail makes source-of-funds documentation straightforward for compliance.

Three integration options: no-code web app, SDK (TypeScript, React/Vue/Angular), or a checkout widget you embed in a few lines.

Would love feedback on our project. Contracts are on GitHub.
