How it works

Four steps. Fully on-chain.

  1. 01

    Seller creates a deal

    Set amount (ETH or USDC), deadline, and terms. Leave buyer blank for an open listing. The deal is immutable from the first block.

  2. 02

    Buyer funds the escrow

    Buyer deposits amount + 0.5% fee. Funds are locked inside the contract. Neither party can access them until the deal resolves.

  3. 03

    Deliver and release

    Seller marks as delivered. Buyer confirms and releases. Funds settle in under one second. Auto-release available after the dispute window.

  4. 04

    Dispute if needed

    5 random community reviewers vote within 48h. Proportional split: 0%, 50%, or 100% to seller. Zero fees if resolved in buyer's favour.

Features

Built for real security.

Non-custodial

Funds held by the contract itself. No operator can access, freeze, or redirect them.

Fair disputes

Proportional — not winner-take-all.

Fully transparent

Every deal, vote, payout — verifiable on-chain.

Auto-refund

Seller misses the deadline? Full refund, no admin.

Source-verified

Contract source verified on Basescan. Audit it yourself.

Minimal attack surface

Compact, immutable Solidity. No proxy, no upgradeability, no owner keys — nothing to compromise.

FAQ

Common questions

After the delivery deadline, the buyer calls claimRefund() directly on the smart contract. No admin required. The refund is automatic and trustless.

5 randomly selected community reviewers vote on the outcome within 48 hours. They can vote 0%, 50%, or 100% to the seller. Majority wins. If nobody votes, the default is a 50/50 split.

Funds are held by an immutable smart contract on-chain. The code is verified on Basescan. Zero admin keys exist — not even the deployer can access the funds.

ETH and USDC on the Base Sepolia network. Additional tokens and mainnet deployment will follow after a formal audit.

No. Connect your wallet and create a deal. No email, no sign-up, no KYC.

0.5% of the deal amount, charged only when funds are successfully released to the seller. Refunded deals and buyer-resolved disputes pay zero fees.
