This repository tracks past and ongoing improvements to Ethereum in the form of Ethereum Improvement Proposals (EIPs). [EIP-1](https://eips.ethereum.org/EIPS/eip-1) governs how EIPs are published. +* EIP-5792: [https://eips.ethereum.org/EIPS/eip-5792#atomicbatch-capability](https://eips.ethereum.org/EIPS/eip-5792#atomicbatch-capability) +* CAIP-25 namespaces: [https://github.com/ChainAgnostic/namespaces/blob/main/eip155/caip25.md](https://github.com/ChainAgnostic/namespaces/blob/main/eip155/caip25.md) -The [status page](https://eips.ethereum.org/) tracks and lists EIPs, which can be divided into the following categories: -- [Core EIPs](https://eips.ethereum.org/core) are improvements to the Ethereum consensus protocol. -- [Networking EIPs](https://eips.ethereum.org/networking) specify the peer-to-peer networking layer of Ethereum. -- [Interface EIPs](https://eips.ethereum.org/interface) standardize interfaces to Ethereum, which determine how users and applications interact with the blockchain. -- [ERCs](https://eips.ethereum.org/erc) specify application layer standards, which determine how applications running on Ethereum can interact with each other. -- [Meta EIPs](https://eips.ethereum.org/meta) are miscellaneous improvements that nonetheless require some sort of consensus. -- [Informational EIPs](https://eips.ethereum.org/informational) are non-standard improvements that do not require any form of consensus. - -**Before you write an EIP, ideas MUST be thoroughly discussed on [Ethereum Magicians](https://ethereum-magicians.org/) or [Ethereum Research](https://ethresear.ch/t/read-this-before-posting/8). Once consensus is reached, thoroughly read and review [EIP-1](https://eips.ethereum.org/EIPS/eip-1), which describes the EIP process.** - -Please note that this repository is for documenting standards and not for help implementing them. These types of inquiries should be directed to the [Ethereum Stack Exchange](https://ethereum.stackexchange.com).
