# Go SDK

> Official Go module for server-side 0xkey API access, signing, and enclave encryption.

The official Go SDK [`github.com/0xkey-io/sdk-go`](https://github.com/0xkey-io/sdk-go) targets **server-side** integrations: Company Wallets, delegated access, OTP backends, wallet automation, and chain-specific signing examples.

<Note>
  **Embedded Wallets** in browser apps use [React Wallet Kit](/sdks/react/getting-started) or [`@0xkey-io/core`](/sdks/typescript-frontend/getting-started). Use Go when your signing logic runs on a trusted backend.

## TypeScript alternative

Node.js backends can use [`@0xkey-io/sdk-server`](/sdks/javascript-server) with the same API key model and built-in Express/Next proxies.
