Welcome to the EVM Playground

The Ethereum Virtual Machine executes bytecode — a sequence of hex-encoded instructions. Each opcode manipulates a stack of 256-bit values. Pick an example below to see it in action, or type your own bytecode.

Visualize how the EVM can execute multiple transactions in parallel when they don't touch the same addresses. Transactions that conflict on shared state must be serialized into separate "waves".

Scenario

8 transactions between different addresses — all can run in parallel.
