Specs

Megaspec

Megaspec is ready and main source of truth.

EIPs

Are aligned with the Megaspec, Meta EOF EIP at https://eips.ethereum.org/EIPS/eip-7692.

Implementations

Besu

Currently EOF is in a branch mega-eof.

erigon++

Erigon++ is a version of Erigon using Silkworm as the execution engine. Since Silkworm uses evmone, it receives the feature from upstream.

ethereumjs

Ethereumjs in 2022 has merged the initial EOF EIPs into mainline, and then worked on the late 2022 version in PR#2453. This code can be considered stale.

geth

Current work-in-progress implementation resides at: ethereum/go-ethereum#29518

Nethermind

Nethermind currently has EOF support in the branch feature/evm/eof (PR#6896).

Solidity

Last implementation resides at ethereum/solidity#13825. This is based on the December 2022 version of EOF.

Vyper

There is a contributor submitted PR from mid 2023 implementing some of EOF: vyperlang/vyper#3457
