Solana Transaction Introspection
Deserialize signed Solana transactions into instructions, signers and blockhash from Ed25519Instruction data for use in payment channels and other L2 settlement scenarios.
Features
- Deserialize Transactions onchain: Deserialize Ed25519Instruction data into a
SignedTransaction
- Return signers: List signers of Ed25519Instruction to validate in your program
Data Structures
SignedTransaction
A struct representing the signed transaction, containing the following fields:
header
: ASignedTransactionHeader
including the number of signers and readonly accounts.signers
: A vector of unique public keys representing the signers of the transaction.recent_blockhash
: The blockhash at the time the transaction was created.instructions
: A vector ofSignedTransactionInstruction
structs representing the transaction's instructions.
SignedTransactionHeader
A struct that holds metadata about the transaction:
signers
: Number of writable signers.readonly_signers
: Number of readonly signers.readonly
: Number of readonly accounts.
SignedTransactionInstruction
A struct representing a single instruction in the transaction:
program_id
: The program ID associated with this instruction.accounts
: A vector of public keys representing the accounts involved in the instruction.data
: A vector of bytes representing the instruction data.
Usage
To deserialize a signed transaction from bytes:
use solana_program::pubkey;
use solana_signer_transaction::SignedTransaction;
fn main() {
let transaction_bytes = [/* Ed25519Instruction data */];
let transaction = SignedTransaction::from_bytes(&transaction_bytes).unwrap();
// Access transaction components
println!("{:?}", transaction.signers);
println!("{:?}", transaction.recent_blockhash);
println!("{:?}", transaction.instructions);
}
Testing
Unit tests are included to verify the correctness of deserialization.
