Transaction Debugging Tools


EVM Equivalence

As Optimism is EVM Equivalent (opens new window), most debugging tools work out the box with Optimism.

# Tenderly

Tenderly (opens new window) lets you inspect any transaction execution, both for Optimism (mainnet) and Optimism Kovan (testnet). You can inspect the state of your verified contract in any step of the transactions execution, as well as step into or over function calls.

# Etherscan

Etherscan (opens new window) allows you to see events as well as revert messages for transactions that have been mind on Optimism (mainnet) as well as Optimism Kovan (testnet). You can see more information about all the L2 features Etherscan offers in our Explorers page.
