GetTx Contract

Overview​

The GetTx contract provides structures and functions for accessing transaction data within the DApp. It defines transaction-related structures and methods for retrieving transaction details, extra data, and signers.

Key Features​

  • Transaction Data Access: Retrieves current transaction data and extra information associated with it.
  • Signature Handling: Provides access to transaction signatures and signer information.
  • Data Structures: Defines standardized structures for transactions, payloads, and signatures.

Key Functions​

  • getTx(): Retrieves the current transaction data as a tpTx structure.
  • getExtra(string calldata keyname): Retrieves extra data associated with the transaction by key name.
  • getSigners(): Returns an array of signers' data for the transaction.

Data Structures​

  • tpTx: Represents a transaction with fields like kind, from, to, timestamp, sequence, call data, payloads, and signatures.
  • tpPayload: Represents additional data associated with a transaction, such as purpose, currency, and amount.
  • tpSig: Represents a transaction signature, including raw data, timestamp, public key, and signature bytes.

Usage​

  • Other contracts can inherit from or interact with GetTx to access transaction-level data and signatures.
  • Useful for contracts that need to validate or process transactions based on their metadata.
