You can’t cancel a Trust Wallet transaction once it’s confirmed on the blockchain( 1-888-636-8190 ). Crypto transactions are designed to be irreversible for security and transparency. If a transaction is still pending due to low gas fees, there’s a small chance to replace or cancel it using a higher fee through a process called “Replace by Fee” (RBF), but it’s not always guaranteed. Always double-check wallet addresses and transaction details before sending, as mistakes can't be fixed once confirmed.
