Short answer

How can I simulate Aptos transactions with my AI?

Your AI uses Nodereal to run transaction simulations and pull account data on the Aptos network. This lets you catch logic errors and estimate gas costs before you commit. You'll get a clear picture of the transaction outcome below.

Validation outcomes

What your AI produces.

The results of a successful simulation run.

LOGIC

Valid transaction payloads

The AI confirms if the transaction structure is correct. You'll know if the payload is ready for the network.

COST

Gas requirement estimates

The AI calculates the expected gas needed for the operation. This helps you avoid failed transactions due to low funds.

STATE

Account status checks

The AI checks the sender's balance and permissions. You get confirmation that the account is ready for the move.

HUMAN

Manual error handling

If the simulation fails, the AI flags the specific error. You decide whether to fix the code or try a different payload.

The workflow

What your AI does when the request arrives.

The AI moves from checking account state to testing the actual transaction logic.

  1. Check account state

    The AI looks up the sender's current balance and resource state to ensure the transaction is possible.

    aptos_get_account

  2. Run simulation

    The AI sends the transaction payload to the network to see how it executes in a sandbox.

    aptos_simulate_transaction

  3. Calculate gas

    The AI pulls the gas cost from the simulation results to provide an estimate.

    aptos_simulate_transaction

  4. Report results

    The AI summarizes if the transaction succeeded or failed and provides the specific error message.

  • Check the balance for account 0x123... to see if it can cover a transfer.

  • Simulate this transaction payload and tell me the estimated gas cost: [hex_data]

  • Verify if this Aptos transaction will fail based on the current account state.

  • Run a simulation for this transaction and list any errors that occur.

FAQ

How this task behaves

  • 01

    Does simulating a transaction spend real gas?

    No. Simulations happen in a sandbox environment and do not cost real Aptos assets.

  • 02

    Can the AI send the transaction to the network for me?

    No. The AI can only simulate and validate the transaction. You must manually sign and broadcast the real transaction using your own wallet.

  • 03

    Can the AI change my account settings?

    No. The tools only allow the AI to read account data and simulate transactions. It cannot modify any on-chain state.

  • 04

    How accurate are the gas estimates?

    The estimates are based on the actual execution results from the network simulation.

  • 05

    What happens if the simulation fails?

    The AI will report the specific error returned by the Aptos network, such as insufficient funds or failed precondition checks.
