Simulate multiple Solana transactions in a single request. Returns the same detailed analysis as the single transaction simulator — instruction parsing, asset transfers, balance changes, state predictions, and account risk scoring — for each transaction in the batch.

When to Use Batch Simulation

Multi-step workflows — Simulate a sequence of dependent transactions together.
Bulk validation — Validate multiple independent transactions in one API call instead of separate requests.
Portfolio operations — Analyze multiple swap or transfer transactions simultaneously.

How to Use

Send a POST request with an array of transactions:

{
  "transactions": [
    {
      "payload": "<ENCODED_TRANSACTION_1>",
      "encoding_type": "base64"
    },
    {
      "payload": "<ENCODED_TRANSACTION_2>",
      "encoding_type": "base64"
    }
  ]
}

Each transaction in the array accepts the same payload and encoding_type parameters as the single transaction endpoint. Cluster support: devnet, testnet, mainnet-beta

Response Format

The response contains an array of results, one per submitted transaction. Each result follows the same schema as the single transaction simulator:

Field	Description
`instruction_groups`	Hierarchical view of all instructions with parsed data.
`asset_transfers`	Detected SOL and token transfers.
`lamport_changes`	Balance changes by address.
`expected_state_changes`	Predicted account-level state updates.
`transaction_risk`	Risk analysis with `accounts_risk_score` and `exploit_risks_detected`.
`returned_data`	Data returned by programs during execution.
`logs`	Complete execution logs.
`transaction_summary`	Compute units, fee breakdown, programs invoked.
`error`	Failure reason if simulation failed for this transaction.

For full details on each field, see the single transaction simulator documentation.
