What is EVM (Ethereum Virtual Machine)?. The EVM is the runtime that executes smart contracts on Ethereum and compatible chains. It defines opcodes, gas costs, and state transitions.
How it works
Contracts compile to bytecode. Nodes run the same code and update state identically, ensuring determinism.
Why it matters
EVM compatibility lets apps and tools work across many networks.
Common pitfalls
- Assuming every EVM chain has the same security
- Ignoring gas implications of complex code
- Using unaudited libraries
Quick example
A developer deploys the same contract to multiple EVM chains with minor configuration changes.
