Deprecation notice

Warning

@zama-fhe/relayer-sdk is deprecated. Please migrate to the Zama SDK, the default SDK for the Zama Protocol. The Relayer SDK will no longer be maintained from 6 November 2026.

Migrate to the Zama SDK

Package	Use it for
@zama-fhe/sdk	Core TypeScript SDK for any JavaScript/TypeScript app. Works with viem or ethers.
@zama-fhe/react-sdk	React hooks built on top of the core SDK. Use this if you are building a React/Next.js app.

# Core SDK
npm install @zama-fhe/sdk

# React hooks (also requires @tanstack/react-query)
npm install @zama-fhe/react-sdk @tanstack/react-query

• 📒 Documentation: docs.zama.org/protocol/sdk
• 🚀 Quick start: Get started with the Zama SDK
• 💻 Source code: github.com/zama-ai/sdk

What this means for you

• Until 6 November 2026, the Relayer SDK only receives dependency security updates: no new features, bug fixes, or protocol updates.
• From 6 November 2026, it will no longer be maintained.
• Existing installs keep working: the package stays available on npm, so your current builds will not break immediately.
• We recommend migrating as soon as possible.
