MetaMask has introduced limit order functionality to its mobile app, enabling users to set target prices for token trades across four blockchain networks without locking up their assets. The feature leverages revocable wallet permissions, allowing traders to maintain custody of tokens while orders remain active. Unlike traditional on-chain limit orders that require funds to be escrowed, MetaMask's implementation keeps tokens in the user's wallet until execution conditions are met. However, hitting a specified target price does not guarantee an automatic fill, as market liquidity and network conditions may affect order completion.
