solana-parser

This is a library containing useful tools to parse and inspect Solana transactions at the most primitive level.

Build

cargo build

Usage

The Solana transaction parser accepts hex string inputs of two types:

• Messages: the "message" portion of the Solana transaction, which is the payload that gets signed by signers, NOT including the compact array of Signatures that comes at the beginning of a full Solana transaction
• Full transactions: this includes both the message, as well as the compact array of signatures (or a placeholder array with zero-signatures) at the beginning

To use the parser include the hex string of EITHER a Solana transaction message or a full Solana transaction. You MUST also include the corresponding flag: --message or --transaction. You must include exactly one of these flags.

# Example for parsing a solana transaction message
cargo run parse --message <your unsigned Solana transaction message>

# Example for parsing a full solana transaction
cargo run parse --transaction <your unsigned Solana transaction>

Examples

See tests for examples using transactions from various scenarios. Here are the corresponding outputs:

Command to parse simple legacy transaction messages:

Further Context

This area provides context on some areas of the parser output that are opinionated, custom abstractions.

Top Level Transfers Array

There is a top level array called Transfers. This does not map 1 to 1 to an abstraction that exists in a Solana transaction, but is more of a custom abstraction for user-friendliness. Specifically it is an array representing all instructions within the instruction list that are simple SOL transfers (expressed in lamports) including the amount, the sender and the recipient of the transfer.

Top Level SPL Transfers Array

Similar to Transfers, there is a top level array called SPL Transfers. This is a custom abstraction for user-friendliness that represents all instructions within the instruction list of a transaction that are SPL token transfers (it includes calls to the Transfer and TransferChecked instructions on the Solana Token Program and Solana Token 2022 Program as well as the TransferCheckedWithFee instruction on the Token 2022 Program). It includes all relevant information to SPL transfers like the sending token account, receiving token account, the signing authority of the sender, the mint account key of the token being transferred etc.

Note: For some SPL transfers, some of the fields may be unused. This is because the three different SPL transfer instructions that are supported, require different levels of information in the instruction call.

Address table lookups

• Context: Versioned transactions in Solana (V0 transactions) include Address Table lookups which are basically references to a location on chain where address strings are stored to be included in the transaction. It is used to fit more addresses into a transaction.
• Currently we do not resolve address table lookups in our versioned transaction parser output but instead have different abstractions to show where the lookup table addresses have been referenced. Specifically:
  • Top level Array – each top level address table lookup object here includes the key of the account where the addresses are stored and then arrays of all writable and read only indexes (two arrays total) used in the transaction
  • Within-instruction array – each instruction contains an array of all addresses that are only lookups and not explicitly included (each object here is a table key + index)

For more on Address Table Lookups: https://solana.com/docs/advanced/lookup-tables

Future considerations

• Resolve Address Table Look Ups: Currently address table lookups are only included as references. In the future we could resolve these to the actual addresses that they represent
