The safest handshake on the internet.
VaultPay holds the money while you make the deal. Funds sit in an immutable smart contract that nobody — including us — can touch. No account, no KYC. Just connect a wallet, trade, release.
Four steps. Zero trust required.
You don't have to trust the other side, and you don't have to trust us. The contract does the holding, the counting, and the paying out.
Seller creates the deal
Item, price in ETH or USDC, and a delivery deadline. Share the link anywhere — or list it on the marketplace.
Buyer funds the vault
The money locks inside the smart contract. From this moment, neither side can touch it — and neither can we.
Deliver, confirm, release
Buyer confirms delivery and the contract pays the seller instantly, minus the 0.5% fee. Done.
If something breaks
Open a free dispute — 5 random reviewers vote within 48h. Deadline missed with no delivery? Automatic full refund.
A real marketplace — not just a contract with a form on top.
Soft on the outside.
Immutable underneath.
Every comfort on this page is backed by something you can verify on-chain. That's the whole idea.
Non-custodial, actually
Your funds never touch our hands — the contract has no owner to hand them to. Money in, money out, math in between.
Fair disputes
Five random community reviewers, 48 hours, proportional outcomes — 0%, 50%, or 100% to the seller. No single judge, no fee.
Fully transparent
Every deal, deadline, and vote lives on Base. If you ever wonder where your money is, the answer is a block explorer away.
Auto-refund
Seller misses the delivery deadline? The contract refunds the buyer in full — automatically. No ticket, no waiting, no asking nicely.
Minimal attack surface
No proxy, no upgrade path, no admin keys, no pause switch. The code you read today is the code that runs forever.
Source-verified
The full contract source is verified on Basescan. Don't trust the marketing site — read the escrow yourself.
Fairness is a spectrum, not a coin flip.
Most escrow gives you two outcomes: buyer wins or seller wins. Real deals are messier than that — so VaultPay's jury can split the vault proportionally.
Five reviewers are drawn at random from the community. They see the evidence, vote within 48 hours, and the contract executes the majority outcome. Opening a dispute costs nothing.
Choose your middleman. Or don't.
Escrow has always meant handing your money to a company and hoping. VaultPay replaces the company with a contract you can read.

Paranoia, formalized.
We designed VaultPay assuming everyone — including a future, eviler version of us — would try to steal from it. Then we removed every way to do so.
- Source-verified on BasescanEvery line of the escrow contract is public and matches the deployed bytecode.
- Zero admin keysNo owner role, no pause switch, no backdoor. There is nothing to phish, leak, or subpoena.
- No proxy, no upgrade pathThe contract is immutable. What you audit today is what runs in ten years.
- Reentrancy-guarded, 129 tests + fuzzingA strict state machine, guarded external calls, and a Foundry suite that runs green before anything ships.
Asked, answered, on-chain.
Do I need a crypto account or exchange?
No account, no sign-up, no KYC. You just need a wallet (like Coinbase Wallet or MetaMask) with testnet ETH or USDC. Connect it, and you're in.
Where is my money while a deal is open?
Locked inside the escrow smart contract on Base — not with us, not with the seller. Nobody holds keys that can move it. You can watch it sit there on Basescan the whole time.
What happens if the seller never delivers?
Every deal has a delivery deadline. If it passes without delivery, the contract issues an automatic full refund to the buyer. No dispute needed, no one to convince.
What does VaultPay cost?
A single 0.5% fee, charged only when a deal releases successfully. Creating deals is free, funding is free, disputes are free, refunds are free.
How do disputes actually work?
Either side can open one, free. Five random community reviewers look at the evidence and vote within 48 hours. The contract executes the outcome proportionally: the seller receives 0%, 50%, or 100%, and the remainder returns to the buyer.
Is this live? Can I use real money?
VaultPay is a beta on Base Sepolia testnet — everything works end-to-end, but with test funds only. We'd rather earn trust in the open than pretend. Mainnet comes when the beta has proven itself.
