EVM Disassembler vs Decompiler
An EVM disassembler converts bytecode into a linear listing of opcodes and operands — the ground truth of what the chain executes. A decompiler goes further, reconstructing control flow and Solidity-like functions. Both views matter; they answer different questions.
When to use disassembly
- Verify exact instructions for gas-sensitive or unconventional patterns
- Debug compiler output or hand-written assembly (Yul)
- Confirm specific opcodes exist (e.g. SELFDESTruct, DELEGATECALL)
- Cross-reference decompiler output against raw execution paths
When to use decompilation
- Quickly understand overall contract purpose and public functions
- Share readable output with non-assembly experts
- Map storage layout and external call patterns at scale
- Prepare ABI recovery and selector databases
