SPECIFICATIONS & TESTING FOR THE ETHEREUM EXECUTION LAYER

# The Source of Truth for Ethereum’s Execution Layer

STEEL bridges EVM research, prototyping, and production: we help researchers forge [EIP](<https://eips.ethereum.org/>) proposals into rigorous specifications and test suites, and we provide the test vectors and frameworks that Execution Layer client developers depend on to verify their implementations.
