tenderly_simulateTransaction - ApeChain


Summary

The method returns:

  • decoded logs,
  • decoded call trace,
  • decoded asset changes (assetChanges),
  • decoded state changes (stateChanges),
  • balance changes (balanceChanges),
  • nonce change,
  • code change (when simulating a code override).

Note: change fields (assets, balance, state and nonce, and code) are omitted if no change has taken place.
