Unleashing Medusa: Fast and scalable smart contract fuzzing

Summary: Trail of Bits released Medusa v1, an open-source EVM-based fuzzer built on Geth and derived from its earlier fuzzer Echidna, aimed at making smart contract fuzzing more scalable and efficient. An internal benchmark against Echidna showed Medusa and Echidna performing similarly in coverage and corpus size, and the firm says it will keep Echidna only for minor bug fixes while shifting primary focus to Medusa.
Bottom line: Trail of Bits is moving its maintenance weight off Echidna, the fuzzer many teams already run, so smart contract teams face a migration decision while the vendor's own benchmark shows no coverage gain yet.
