From handshake to settled.
Every Middn trade follows the same path. No surprises. No middlemen pulling strings behind the curtain. Here's exactly what happens, step by step.
Connect your wallet.
No signup form. No email. No password. Just plug your web3 wallet into Middn — MetaMask, Rabby, Coinbase Wallet, Phantom — whatever you already use.
- Works with every major wallet
- Multi-chain support (Ethereum, Base, Arbitrum…)
- We never see your keys
Design the deal.
Tell Middn what you're trading. Send 2,500 USDC, receive 1.428 ETH, deliver an NFT, sell tokenized property — anything. The AI helps shape the terms and flags anything that looks off.
- Pick assets on both sides
- Set release conditions
- AI suggests fair pricing
Send the invitation.
Middn creates an encrypted link you share with your counterparty. They open it, review the terms, and sign on-chain. The link is end-to-end encrypted — no one else can peek.
- E2E encrypted (AES-256 + X25519)
- One-time link, expires after use
- Share by DM, email, or QR code
Lock the funds.
Both sides deposit their assets into the smart contract. The contract holds everything until conditions are met. Middn never touches the funds — they're locked in code, not in our wallet.
- Audited by Trail of Bits & Halborn
- Funds visible on-chain in real time
- Refundable if the trade doesn't close
ZK verifies the conditions.
Before release, the contract checks that all conditions are met using zero-knowledge proofs. It can prove "yes, this is legit" without ever exposing the data — your amounts, balances, and identity stay private.
- Groth16 zk-SNARKs
- No data on-chain, only proof
- Compliance without exposure
Atomic settlement.
Both legs of the trade release in the same on-chain transaction. Either both sides get what they were promised — or neither does. No partial outcomes, no being left holding the bag.
- All or nothing — no half trades
- Settled in ~12 seconds
- Verifiable forever on-chain
