Go SDK - 0xkey

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

Embedded Wallets in browser apps use React Wallet Kit or @0xkey-io/core. Use Go when your signing logic runs on a trusted backend.

Status

Item	Status
Published module (`go get`)	Supported — `v0.1.0+`
Generated API client	Supported
Examples (OTP, delegated access, signing)	Supported
Parity with every TypeScript helper	Partial — prefer TypeScript server SDK for Next.js proxies

Quick install

go get github.com/0xkey-io/sdk-go@latest

Getting started walks through API keys, Whoami, and local api.0xkey.com configuration.

API key authentication	Yes
Wallet / policy / user management	Yes
Sign transaction / raw payload	Yes
Email OTP with HPKE (`pkg/enclave_encrypt`)	Yes

TypeScript alternative

Node.js backends can use @0xkey-io/sdk-server with the same API key model and built-in Express/Next proxies.
