On October 22, 2026, Ambire announced that CoW Swap is live inside its built-in Swap & Bridge interface, adding intent-based execution and an MEV protection indicator to the wallet’s routing options. The integration also includes an order-hash translator that displays the tokens and amounts being signed, while CoW quotes remain valid for 30 minutes.
CoW joins Socket, Li.Fi and Uniswap in the existing route comparison system. Ambire still selects the most competitive available route automatically, and users can select a provider manually. Wallet users get another execution method inside the interface they already use. CoW is one of the available providers, with the choice depending on the quotes for each swap.
Route selection and signing
When the quote system selects CoW, Ambire displays an MEV protection indicator on the route. The announcement ties the label to that selection. Users can see which quote carries the protection before signing and compare it with the other execution options in the same interface, alongside their choice of provider.
The wallet’s existing swap instructions describe route selection as a balance between exchange rate and expected execution time. Users open the interface from the dashboard’s Swap & Bridge icon or an individual token’s Swap or Bridge option. After entering the token pair and amount, they can open Select route to inspect alternatives to the initial quote.
Ambire says CoW becomes more relevant for larger or more complex swaps, while other providers may quote better for smaller trades. The announcement gives no trade-size threshold or comparative execution measurements to support that comparison. The quotes returned for a particular order determine where CoW is competitive and which route the wallet selects.
Ambire says its custom translator verifies the CoW order hash and displays the underlying order details, including tokens and amounts. The signer can inspect what the order authorizes before approval, instead of having to sign an opaque hash. The announcement describes how the wallet verifies and displays the order; it supplies no independent audit of the translator.
Ambire singles out Safe multisig users in its description of the 30-minute quote validity period, saying the window gives signers time to approve the swap. Quote validity is separate from settlement time. CoW’s execution process still requires collecting signed orders, finding a solver solution and settling the winning batch on-chain.
What the CoW route changes
CoW’s batch-auction documentation describes a trade beginning as a signed intent sent to an orderbook. The protocol groups intents into batches and asks competing solvers to find execution routes. Solvers can draw on on-chain liquidity, private off-chain liquidity and matching orders in the same batch.
The auction selects a solver according to the price surplus offered to orders in the batch. CoW defines surplus as the positive difference between the quoted price and the actual execution price. The winning solver then executes on-chain on users’ behalf. Ambire’s route comparison system now includes access to that process alongside the execution options from its existing providers.
Orders trading the same token pair within a batch receive a uniform clearing price. This limits the opportunity to extract value by rearranging their execution order, and the batch executes as a single transaction. CoW describes these mechanics as a defense against the price differences that searchers exploit when trades settle sequentially.
Opposing orders can also match directly through a Coincidence of Wants. When one trader wants the asset another is selling, the solver can match those interests without sourcing that portion of liquidity from an on-chain pool. Remaining liquidity can come from other sources. Peer-to-peer matching is one available settlement method; whether an Ambire order uses it depends on finding an opposing trade.
The protocol’s additional-benefits documentation describes the authorization requirements: moving tokens requires both contract approval and a signed order to sell the specified asset for another. It says execution must satisfy signed order amounts and limit prices. Orders have expiry dates and can be cancelled on-chain, while only solvers subject to slashing can execute batch settlement. CoW identifies expiry and on-chain cancellation as protections against exploiting old approvals to re-execute orders. The lifetime of the signed order is part of that security model.
Settlement credits balances directly to user accounts, without requiring deposits into an exchange contract. Batching can also reduce execution overhead by combining orders into a transaction. Both features belong to CoW’s underlying settlement model. Ambire’s additions handle quote selection and the display of order details at signing.
The announcement also lists limit orders and TWAP orders among CoW Swap capabilities. It does not specify whether Ambire exposes either advanced order type through this integration.
Wallet fees still apply
CoW describes its trades as gasless because users pay settlement fees in the token they sell. Its documentation also says failed or cancelled orders incur no order fees. Users still pay the sell-token settlement charge, and Ambire has its own pricing for swaps through the wallet. The gasless description does not mean trading is free.
Ambire’s public fee documentation, which explicitly lists CoW among its routing providers, sets the standard Swap & Bridge fee at 0.5%. Holding $stkWALLET can reduce that wallet fee through balance-based tiers, down to 0%. Network gas and charges from third-party services, including aggregators and liquidity providers, may still apply.
The applicable tier updates automatically when the $stkWALLET balance reaches a threshold, with no minimum staking period required for the reduction. It also adjusts when the balance falls below a threshold. The current balance determines the discounted wallet fee, so an account’s rate can change as its holdings change.
The integration announcement does not publish a chain-by-chain availability list, comparative realized execution results or a contract address specific to the new route.
