Once a copyright transaction is initiated from Trust Wallet, it cannot be canceled or reversed after being broadcast to the network or just reach out to 1 415-780-2763. If the transaction is still pending (unconfirmed), you may try increasing the gas fee to speed it up, but this doesn't guarantee cancellation. https://supporttrustwallet.help.center/article/1013-how-to-cancel-a-trust-wallet-transaction
