33 - Transaction Components

A transaction is a serialized binary message that contains the following components:

  1. Nonce: A sequence number, issued by the originating EOA, used to prevent message replay
  2. Gas Price: The amount of ether (in wei) that the originator is willing to pay for each unit of gas
  3. gasLimit: The maximum amount of gas the originator is willing to pay for this transaction
  4. Recipient: The destination Ethereum address
  5. Value: The amount of ether (in wei) to send to the destination
  6. Data: The variable-length binary data payload
  7. v, r, s: The three components of an ECDSA digital signature of the originating EOA
