A signed transaction is a digital agreement that allows two parties to exchange ETH or other digital tokens. This type of transaction is made possible by the use of public and private key pairs.
The public key is used to encrypt the message, and the private key is used to decrypt it.
In order for a signed transaction to be valid, it must be signed with the sender’s private key. The recipient’s public key can then be used to verify that the signature is valid.
If the signature is invalid, the transaction will be rejected.
Once a signed transaction is created, it can be sent to the Ethereum network for confirmation. Once it is confirmed, the ETH or other digital tokens will be transferred from the sender’s account to the recipient’s account.
