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](https://github.com/hashgraph/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](https://docs.hedera.com/hedera/tutorials/smart-contracts/hscs-workshop/hardhat) , enabled by the [JSON-RPC Relay,](https://docs.hedera.com/hedera/core-concepts/smart-contracts/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](https://docs.hedera.com/hedera/tutorials/smart-contracts) 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](https://github.com/hashgraph/hethers.js/) , it will **no longer** receive official support and updates after the deprecation date. Please share any feedback or questions via the [#feedback](https://discord.gg/hedera) channel on Discord. We’re here to help with the transition. #### **Timeline** - Now until October 20, 2023: Transition from hethers.js to EVM tooling. - October 20, 2023: Official deprecation of hethers.js with no further updates or support. #### **Continue Learning** - [Open a Testnet Account](https://portal.hedera.com/register) - [Try Examples](https://docs.hedera.com/hedera/tutorials) and [Tutorials](https://docs.hedera.com/hedera/tutorials/more-tutorials) - [Join the Developer Discord](https://hedera.com/discord) - [Read the Learning Center](https://hedera.com/learning) - [Read the Hedera Blog](https://hedera.com/blog) [Back to Blog](/blog) discover See more articles [View All](/blog) ![Image](https://hedera.com/wp-content/uploads/2026/08/Regulation_Blog-1024x576.png) August 5, 2026 ### Details decide.
