How Vaultion works
Vaultion is a non-custodial crypto escrow. Funds are locked in an open-source smart contract and released only when both parties agree — or when a dispute ruling decides: your choice of independent Kleros jurors or a Vaultion reviewer on Ethereum, and a Vaultion reviewer on every other network. We never hold your money.
Start an escrowFour steps, all on-chain
Define the deal
The buyer sets the amount, picks a stablecoin, and enters the seller’s wallet address. The platform fee is taken once up front; the remaining amount is what gets locked.
Funds lock on-chain
The escrow smart contract holds the funds — not Vaultion. The balance is visible on the block explorer at any time, so both sides can confirm the money is locked and untouched.
Release on agreement
When the buyer confirms the deal is done, the funds release to the seller. A seller can also refund the buyer. Every release or refund is its own on-chain transaction you can verify.
Or a ruling decides
If the two sides disagree, either can open a dispute. The evidence is reviewed by independent Kleros jurors or a Vaultion reviewer on Ethereum, or a Vaultion reviewer on every other network, and the contract enforces the ruling automatically. On Ethereum you choose which of the two you want when you create the escrow: pick Kleros and the outcome is decided independently of Vaultion; pick a Vaultion reviewer and it is ours. On every other network the reviewer is ours, and we say so.
You can check everything yourself
Vaultion runs on a published, open-source contract. You don't have to take our word that funds are safe or that we can't touch them — the contract is public and you can read it before you ever send anything.
Frequently asked
Who holds my funds during the escrow?
The escrow smart contract holds them — not Vaultion. We never take custody. The contract releases the funds only on your instruction or on a dispute ruling, and you can watch the locked balance on the block explorer the entire time.
What happens if the buyer and seller disagree?
Either party can open a dispute. Both sides submit evidence, then it is reviewed and ruled on by independent Kleros jurors or a Vaultion reviewer on Ethereum, or a Vaultion reviewer on every other network. The contract enforces whatever is decided, and cannot move the funds anywhere the ruling does not.
What does it cost?
A tiered platform fee — 4% on smaller deals down to 2% on larger ones — is paid once, when the escrow is created. On Kleros escrows (Ethereum), arbitration is separate: it is paid in ETH and only by the party that raises a dispute — the live cost is shown in the escrow view before you commit. Vaultion-assisted escrows have no arbitration fee. If no dispute is raised, there is no arbitration fee either way.
Which stablecoins and networks are supported?
On Ethereum: USDC, USDT, DAI, and PYUSD. On Arbitrum One: USDC, USDT, and DAI. On Base: USDC and DAI. More chains are planned.
Is Vaultion live?
Yes. Vaultion is live with real funds on Ethereum mainnet, Arbitrum One, Base, BNB Smart Chain, TRON, and Solana. Always verify the contract address on the block explorer before sending funds.
