Deprecated software

This is a list of key Ethereum-related projects and resources which have been deprecated or are no longer maintained. It is important to highlight deprecated work so that users can find viable alternatives and to prevent malicious versions from being distributed.

This list is curated by our community. If there's something missing or incorrect, please edit this page!

Software

This section is for software for the desktop, command line, or server which has been deprecated. The main types are wallets, integrated development environments, languages, and Ethereum clients. Definitely be careful to not install deprecated software unless you are certain it is from the original source, e.g. a repo hosted under https://github.com/ethereum.

Grid

Deprecated on December 10, 2020

Summary

Grid was a Javascript-based desktop application that allowed you to securely access Ethereum, IPFS, and other decentralized networks. It provided a user-friendly interface to assist a less technical audience in safely interacting with dapps, which increased accessibility for everyone.

Archives

Archived GitHub repo

History

Grid could be seen as a successor to Mist, also a standalone, Javascript-based desktop app which included a Geth node. Grid removed the wallet aspect, and added a plugin-style approach for running different kinds of nodes.

Archived GitHub repo

History

Ethereum Studio was developed to provide users with an IDE that had a built-in Ethereum blockchain and Solidity compiler. In addition to this it provided the ability to live edit code and export full DApps without the need for a terminal.

Alternatives

Remix is an alternative web IDE for Solidity development. Additionally, the Developer Portal has tools for web and local development, documentation, and more.

Meteor Dapp Wallet

Deprecated on March 27, 2019

Summary

Meteor Dapp Wallet was a component of Mist, an Ethereum wallet for managing Ethereum accounts and interacting with smart contracts. For many years the Meteor Dapp Wallet web UI was hosted as a subdomain "wallet.ethereum.org".

The Mist Multisig Contract (solidity code) was also included, and Meteor Dapp Wallet featured a user interface for configuring and deploying it.

Not deprecated: deployed Mist Multisigs

The Mist Multisig -- deployed as bytecode to Ethereum mainnet by thousands of users -- continues to be used to store and manage value without incident. How to Interact with a Mist Multisig Contract provides a good overview for how to use these smart contracts.

Parity

Deprecated on June 2, 2020

Summary

Parity was an Ethereum client written in Rust.

Archives

Archived GitHub repo

History

As one of two major, viable clients in the early years of Ethereum (the other being Geth), Parity was a crucial part of the ecosystem. During the Shanghai Attacks of 2016 Parity enabled Ethereum network to continue operating when clients like Geth were taken down by the attack, proving the importance of client diversity.

Alternatives

The successor project to Parity Ethereum client is Open Ethereum.

The "Spin up your own Ethereum node" resource on ethereum.org includes a section for downloading, installing, and running an Ethereum client.

Trinity

Deprecated on July 1, 2021

Summary

Trinity was a python-based Ethereum client which served as a research and educational tool for the community. A large number of python-based modules related to Trinity continue to be maintained by the same team, including Py-EVM.

Archives

Archived GitHub repo

History

Trinity was the successor project to pyethereum, an early python-based Ethereum client.

Alternatives

The "Spin up your own Ethereum node" resource on ethereum.org includes a section for downloading, installing, and running an Ethereum client.

The EthereumJS project has a similar research and educational use-case as Trinity did.

Dapps and Services

This section is for services deployed to Ethereum mainnet and other EVM-based networks. Be aware that the dapps and services here may include DeFi applications which have been hacked or may suffer security vulnerabilities due to lack of maintenance, changes in the protocol, etc.

The DAO

Hacked and shut down in Summer 2016

Summary

The DAO was a smart contract, dapp, and forum for organizing the funding of projects. A vulnerability was exploited and much of the ETH was drained, leading to a community-organized hard fork in order to return ETH to those who had deposited to The DAO. The UX front-end and forum are discontinued.

Archives

Archived GitHub repo for Legacy Wiki

History

Legacy Wiki was a GitHub wiki and a very early locus of technical content (including the original Ethereum White Paper). Over time, Ethereum developers migrated their documentation, specifications, and technical description work to other platforms like Read the Docs and GitHub-hosted content.

In 2019 and 2020, eth.wiki became the successor to Legacy Wiki, but an enduring community of contributors did not materialize.

Alternatives

Community-driven content: Ethereum.org Website, EthHub Docs

Ethereum software projects often host their documentation on Read the Docs

GitHub-hosted technical specifications: EIPs, Execution Specs, Consensus Specs
