Hedera is committed to providing developers with easy-to-use and up-to-date tools and resources. With that goal in mind, Hedera core contributors are announcing the deprecation of the hethers.js library by October 20, 2023.
Why is Hethers.js Being Deprecated?
With Hedera becoming increasingly EVM-equivalent, the need to maintain a separate library like hethers.js is diminishing.
-
Native EVM tooling like ethers.js and web3.js, enabled by the JSON-RPC Relay, can now be used to deploy and interact with Hedera smart contracts.
-
Focusing on EVM tooling provides a more unified developer experience. Developers who are familiar with Ethereum can now easily transition to building on Hedera.
-
Deprecating hethers.js reduces redundancy and consolidates the toolset developers need to work with.
Action for Developers Currently Using Hethers.js
If you currently use hethers.js, you should transition to ethers.js, web3.js, or other EVM tooling before October 20, 2023.
Refer to the Hedera documentation on using tools like web3.js, ethers.js, Hardhat, Foundry, Truffle, and The Graph. Tutorials can be found in the smart contract section.
While hethers.js will remain available on GitHub, it will no longer receive official support and updates after the deprecation date.
Please share any feedback or questions via the #feedback channel on Discord. We’re here to help with the transition.
