Avalanche transaction simulation API

Simulate a Avalanche transaction against current state before it's signed. Preview asset changes, approvals and reverts so wallets and apps can warn users instead of letting a bad transaction land.

Dry-run against live Avalanche state

Submit a transaction for simulation and get back the balance changes, emitted events and revert reason it would produce on Avalanche — no gas spent, nothing broadcast.

Protect users pre-signature

Show 'you will receive / you will send' previews and block obviously malicious calls before the user signs, using the same key as the rest of your integration.

Can I preview asset changes before signing on Avalanche?

Yes — simulation returns the net balance and approval changes a transaction would cause.

Does simulation broadcast the transaction?

No — it runs against state without submitting anything to the Avalanche network.
