EIPs

Ethereum Improvement Proposals (EIPs) describe standards for the Ethereum platform, including core protocol specifications, client APIs, and contract standards.

Contributing

First review EIP-1. Then clone the repository and add your EIP to it. There is a template EIP here. Then submit a Pull Request to Ethereum's EIPs repository.

EIP status terms

• Draft - an EIP that is open for consideration
• Accepted - an EIP that is planned for immediate adoption, i.e. expected to be included in the next hard fork (for Core/Consensus layer EIPs).
• Final - an EIP that has been adopted in a previous hard fork (for Core/Consensus layer EIPs).
• Deferred - an EIP that is not being considered for immediate adoption. May be reconsidered in the future for a subsequent hard fork.
