Bytecode to Opcode

Disassemble EVM bytecode into human-readable opcodes. Enter a contract address to pull its runtime bytecode, or paste raw bytecode directly.

The program counter (PC) is shown in hex, matching how JUMP/JUMPI targets are addressed. PUSH instructions carry their immediate operand in the Push Data column. Opcodes cover the EVM through the Cancun fork (PUSH0, TLOAD/TSTORE, MCOPY, BLOBHASH).
