Fields

pre_execution_accounts_configs: Vec<Option<RpcSimulateTransactionAccountsConfig>>

Per-tx pre-execution account snapshot hints. When provided MUST have the same length as RpcBundleRequest.encoded_transactions. Omitting the field (or sending an empty array) is allowed — the server treats it as “no snapshots requested for any tx”, equivalent to sending vec![None; bundle_len]. Mismatched non-empty lengths are rejected with invalid_params.

post_execution_accounts_configs: Vec<Option<RpcSimulateTransactionAccountsConfig>>

Per-tx post-execution account snapshot hints. Same shape and “omitted = no snapshots” rules as pre_execution_accounts_configs.

transaction_encoding: Option<UiTransactionEncoding>

Encoding the transactions are submitted in. Only Base64 is supported — the server rejects any other value with invalid_params. Matches Jito’s reference simulateBundle, which also enforces base64 only.

simulation_bank: Option<SimulationSlotConfig>

Which bank to simulate against. Surfpool always treats this as Tip-equivalent (the working SVM); accepted for API compatibility.

skip_sig_verify: bool

Skip signature verification. Required when replace_recent_blockhash is true (the resigned blockhash invalidates any pre-existing sig).

replace_recent_blockhash: bool

Replace each tx’s recent blockhash with the bank’s current latest blockhash. Useful for replaying historical transactions.
