MetaMask brings limit orders to mobile, with tokens staying in your wallet

MetaMask rolled limit orders into its mobile wallet, the provider said on Nov. 10. The feature works on Ethereum, Base, BNB Smart Chain and Robinhood Chain, and shows up in the Swap interface on MetaMask Mobile v8.18.0 and later. Instead of swapping at the current rate like a market order, users set conditions and let the trade wait.

Placing an order hands MetaMask a revocable permission to execute a specific swap for a specified amount once the price condition is met, according to the wallet's support guide. Tokens stay in the user's wallet rather than getting locked up. The first order automatically upgrades the account to a smart account capable of granting that permission, and that upgrade can carry a network fee shown at confirmation. The setup covers take-profit and stop-loss sales, plus buys triggered when prices move above or below the market.

Both tokens in a pair must live on the same network, and at least one of them has to support MetaMask's collection of network fees from the swap. Minimums are $100 on Ethereum and $10 on each of the other three chains. Users pick an expiry, with documented examples spanning 10 minutes, one hour, one week and one month.

The default price tolerance is 3% and can be adjusted when the order is created. It absorbs slippage, price impact and the network fee taken out of the tokens, so the final proceeds can land away from what the target price implies. A chart briefly touching the target doesn't guarantee a fill — if no live quote fits inside the tolerance, the order stays open until it executes or expires. MetaMask says its Swaps service pulls quotes from decentralized exchanges and token-swapping protocols rather than supplying liquidity itself.

MetaMask's standard swap fee currently sits at 0.875%, calculated when the order executes and including any applicable discount. The wallet says the charge won't top the standard rate. Network fees are separate and come out of the tokens being sold, so users don't need the chain's native token to cover execution. Creating or cancelling an order costs nothing extra beyond any gas for that initial account upgrade.

Open orders can be cancelled for free unless they're already executing, and tweaking the price, amount or expiry means cancelling and replacing the order. If the source balance falls short at execution, the order auto-cancels. An expired order swaps nothing, and the tokens stay put.
