Solana Module

The Solana module parses transactions for the Solana blockchain, handling multiple instructions, programs, and SPL tokens.

Architecture Overview​

Transaction Model​

  • Encoding: Borsh/Bincode serialization
  • Instruction-based: Multiple instructions per transaction
  • Account Model: Accounts owned by programs
  • Fee Model: Fixed base fee with optional priority fees

Key Components​

The Solana parser handles:

  • System program transfers
  • SPL Token operations
  • Associated Token Account (ATA) creation
  • Multiple instructions per transaction
  • Program invocations

Transaction Structure​

Solana transactions consist of:

  1. Signatures: One or more transaction signatures
  2. Message: Contains the actual transaction data
    • Account keys (all accounts involved)
    • Instructions (operations to execute)
    • Recent blockhash (for replay protection)

Instruction Types​

System Program​

  • SOL transfers between accounts
  • Account creation and initialization
  • Space allocation for data storage

SPL Token Program​

  • Token transfers
  • Token approvals
  • Mint and burn operations

Associated Token Account​

  • Automatic creation of token accounts
  • Deterministic addressing for user tokens

Visualization Strategy​

Primary Information​

Display the most significant instruction as the title, with supporting instructions shown as steps.

Multiple Instructions​

Group related instructions together, showing them as a sequence of operations.

Account Context​

Show account ownership and program associations when relevant.

Supported Programs​

The parser recognizes common Solana programs:

  • System Program
  • SPL Token Program
  • SPL Associated Token Account Program
  • Custom programs via IDL (Interface Definition Language)

Example Transaction Types​

SOL Transfer​

Simple transfer of native SOL between accounts.

SPL Token Transfer​

Transfer of SPL tokens, often including ATA creation if needed.

Complex DeFi Transaction​

Multiple instructions working together (e.g., create account, transfer tokens, interact with DEX).
