What is Transaction Decoding?

Transaction decoding converts raw hexadecimal transaction data into human-readable fields like sender, recipient, value, gas parameters, and transaction data. Raw transactions are RLP-encoded and signed.

■ 02

How does it work?

The decoder parses RLP-encoded transaction data by deserializing the hex string into its component fields. It extracts the transaction type, then decodes each field according to the transaction schema (legacy, EIP-2930,…
