Implementations

impl SolanaTransactionValidator

pub fn validate_allowed_token( token_mint: &str, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

pub fn validate_fee_payer( tx: &Transaction, relayer_pubkey: &Pubkey, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s fee payer matches the relayer’s address.

pub async fn validate_blockhash<T: SolanaProviderTrait>( tx: &Transaction, provider: &T, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s blockhash is still valid.

Checks if the provided blockhash is still valid on-chain. If the blockhash has expired, the transaction will fail when submitted.

Note: For single-signer transactions, expired blockhashes can be refreshed during resubmission. However, validation still occurs to provide early feedback. For multi-signer transactions, expired blockhashes cannot be refreshed without invalidating existing signatures, so validation is critical.

pub fn validate_max_signatures( tx: &Transaction, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates the number of required signatures against policy limits.

pub fn validate_allowed_programs( tx: &Transaction, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s programs are allowed by the relayer’s policy.

pub fn validate_allowed_account( account: &str, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

pub fn validate_tx_allowed_accounts( tx: &Transaction, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s accounts are allowed by the relayer’s policy.

pub fn validate_disallowed_account( account: &str, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

pub fn validate_tx_disallowed_accounts( tx: &Transaction, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s accounts are not disallowed by the relayer’s policy.

pub fn validate_data_size( tx: &Transaction, config: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates that the transaction’s data size is within policy limits.

pub async fn validate_lamports_transfers( tx: &Transaction, relayer_account: &Pubkey, ) -> Result<(), SolanaTransactionValidationError>

Validates that the relayer is not used as source in lamports transfers.

pub fn validate_max_fee( amount: u64, policy: &RelayerSolanaPolicy, ) -> Result<(), SolanaTransactionValidationError>

Validates transfer amount against policy limits.

pub async fn validate_sufficient_relayer_balance( fee: u64, relayer_address: &str, policy: &RelayerSolanaPolicy, provider: &impl SolanaProviderTrait, ) -> Result<(), SolanaTransactionValidationError>

Validates transfer amount against policy limits.

pub async fn validate_token_transfers( tx: &Transaction, policy: &RelayerSolanaPolicy, provider: &impl SolanaProviderTrait, relayer_account: &Pubkey, ) -> Result<(), SolanaTransactionValidationError>

Validates token transfers against policy restrictions.

pub async fn simulate_transaction<T: SolanaProviderTrait>( tx: &Transaction, provider: &T, ) -> Result<RpcSimulateTransactionResult, SolanaTransactionValidationError>

Simulates transaction
