Simulate Solana transactions
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:
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: For full details on each field, see the single transaction simulator documentation.
