With no account password or customer support, how can the blockchain know that a transfer was sent by you?
Digital signatures use a pair of keys: the private key creates the signature, and the public key verifies it. You can’t derive the private key from the public key.
Before signing, check the operation type, contract address, and amount in the confirmation window. If you don’t understand them, don’t sign.
When transferring out $BTC , the wallet signs the transaction with your private key, and nodes across the network verify the signature using the public key.
