BesuFuzz

BesuFuzz is where all the besu guided fuzzing tools live.

eof-container

Performs differential fuzzing between Ethereum clients based on the txparse eofparse format. Note that only the inital OK and err values are used to determine if there is a difference.

Prototypical CLI Usage:

BesuFuzz eof-container \
  --tests-dir=~/git/ethereum/tests/EOFTests \
  --client=evm1=evmone-eofparse \
  --client=revm=revme bytecode

Prototypical Gradle usage:

./gradlew fuzzEvmone fuzzReth

There are pre-written Gradle targets for fuzzEthereumJS, fuzzEvmone, fuzzGeth, fuzzNethermind, and fuzzReth. Besu is always a fuzzing target. The fuzzAll target will fuzz all clients.
