Practical Opcode Tracing Forge College

Summary

Why does a contract abort at runtime even when the source looks correct? Instruction-level Can you explain why an Ether transfer reverted even though inputs looked correct? Where is gas actually spent in a transaction, and how do you turn raw Why did this transaction revert and which internal call changed contract storage? Transaction Why inspect raw EVM execution instead of logs? Low-level Can you read raw EVM bytecode and predict what the runtime will do? This lesson shows how the EVM encodes instructions as ... Where is your smart contract actually spending gas and latency? Converting annotated EVM What exactly happens inside the EVM when a contract call runs and gas is consumed? This lesson shows you how to Want to pinpoint why a transaction failed or where a performance hotspot hides? Event logs are the glue between Want to step through a live Ethereum transaction locally to validate
