Vant8's CoW Protocol surface lets you sign a limit order off-chain and forget it. Your connected wallet signs the order — not the Blockchain Wallet — so every limit order is consciously authorised by you. CoW's solver network executes when your price is reachable, in a batch auction that can't be front-run. No gas to place. No gas to cancel. Zero protocol fee. No Vant8 markup.
Five steps. You see every one of them in the order ticket — and you can cancel for free at any time before settlement.
Pick a chain, pick a pair, set the side, amount, limit price, and expiry. Common expiries from 1 hour up to 7 days.
Your wallet signs the order off-chain using EIP-712 typed data. No transaction broadcast yet — and no gas spent.
The signed order is sent to CoW's order book. From this point, CoW's solver network competes to fill it inside the next batch.
When your limit price is reachable, the order settles inside CoW's atomic batch auction — so it can't be front-run.
If your price isn't reached before the expiry, the order expires. You can cancel earlier — also gas-free.
Wired against CoW Protocol's supported chains. Token lists come from CoW's canonical lists per chain so you only see assets the protocol can actually settle.
Orders are matched off-chain and settled in batch transactions where every order in the batch clears at the same price. The auction structure removes the sandwich and front-running attack surface that hits a public-mempool AMM swap.
You sign — you do not broadcast. There is no on-chain transaction to place, modify, or cancel an order. Cancellation costs nothing.
CoW charges no protocol fee for filled orders. Vant8 adds nothing on top — this is a pure pass-through surface.
The order's status is synced from CoW's order-book API on a short polling interval. You see pending-signature, open, executed, expired, cancelled, or failed in near real time.
Each order links out to the CoW Protocol Explorer so you can see the on-chain settlement and the solver that filled it.
Cancel any open order with a single off-chain signature. No mining cost, no race against a pending transaction.
CoW solvers may settle your order at a price better than your limit when they can — competing solvers sometimes return surplus to your fill. This is a possibility, not a guarantee.
A few operational details worth knowing so you can plan your workflow around what the CoW surface covers — and where other Vant8 surfaces handle the rest.
A CoW order executes when a solver can fill it at your price or better. If you need an immediate fill at market, route through the Smart Order Router instead.
Orders are configured as non-partial-fillable. The order either fills entirely in a batch or stays open until it does — no partial executions to manage.
Signatures use EIP-712 typed data from an externally owned account. Smart-contract wallet signatures (Safe / Gnosis) aren't wired through this surface yet.
There's no built-in “cancel if not filled in N hours” rule — that decision is yours. Cancellation is a free off-chain signature at any point before settlement.
CoW Protocol settles spot trades. Perpetual futures execute through Hyperliquid and connected CEX-perp accounts, not through this surface.
CoW Protocol limit orders are available on every plan. Connect a wallet, sign once, and let solvers do the rest.
