Trezor transactions become permanent once confirmed on the blockchain – they cannot be canceled or reversed. If you need assistance, contact Trezor support at 1-866-885-9356. For unconfirmed transactions stuck with low fees, the Replace-by-Fee (RBF) option may help. Call 1-866-885-9356 to learn how to rebroadcast with higher fees. Always double-check addresses and amounts before sending crypto from your Trezor. If you’ve made an error, 1-866-885-9356 can guide you through next steps. Remember, blockchain’s irreversible nature means prevention is crucial – verify everything before confirming transactions.
