Testnet contracts

The addresses below are the live NEAR Auth deployment on NEAR testnet. Use them for development and integration testing — testnet needs no approval, and you can point your SDK at these contracts today with the shared credentials on this page.

Testnet requires no sign-off. When you’re ready to go live, review the mainnet contracts and apply for production access.

Contract addresses

Contract	Account id	Description	Explorer
NEAR Auth	`fast-auth.testnet`	Entry-point contract that routes verification and requests MPC signatures.	View
JWT Guard Router	`jwt.fast-auth.testnet`	Registry mapping each guard name to its guard contract.	View
Auth0 Guard	`auth0.jwt.fast-auth.testnet`	Guard that RS256-verifies Auth0 JWTs and their claims on-chain.	View
MPC	`v1.signer-prod.testnet`	Multi-Party Computation network that produces signatures from distributed key shares.	View

In the SDKs, fast-auth.testnet is the fastAuthContractId and v1.signer-prod.testnet is the mpcContractId. To learn what each contract does, see the contracts overview.

Network information

Setting	Value
Network	NEAR Testnet
Chain id	`testnet`
RPC endpoint	`https://rpc.testnet.near.org`
Explorer	testnet.nearblocks.io

import { connect } from "near-api-js";

const { connection } = await connect({
  networkId: "testnet",
  nodeUrl: "https://rpc.testnet.near.org",
});

Auth0 credentials

Testnet ships with a shared Auth0 client so you can start authenticating users without registering your own tenant. The JavaScript provider fills in the domain and signing audience from the testnet network, so clientId is the only value you need to supply.

Setting	Value
clientId	`np8paqIpMWmNbzT4xAvOOapZBjsOpptl`
domain	`login.testnet.fast-auth.com`
signing audience	`auth0.jwt.fast-auth.testnet`

import { JavascriptProvider } from "@fast-auth-near/javascript-provider";

const provider = new JavascriptProvider({
  network: "testnet",
  clientId: "np8paqIpMWmNbzT4xAvOOapZBjsOpptl",
});

This clientId is shared across testnet apps and is intended for development only. Provision your own Auth0 credentials before moving to mainnet.

Wire it up

The full browser client config for testnet combines the contract addresses and the Auth0 provider above.

main.ts

import { FastAuthClient } from "@fast-auth-near/browser-sdk";
import { JavascriptProvider } from "@fast-auth-near/javascript-provider";
import { connect } from "near-api-js";

const provider = new JavascriptProvider({
  network: "testnet",
  clientId: "np8paqIpMWmNbzT4xAvOOapZBjsOpptl",
});

const { connection } = await connect({
  networkId: "testnet",
  nodeUrl: "https://rpc.testnet.near.org",
});

const client = new FastAuthClient(provider, connection, {
  fastAuthContractId: "fast-auth.testnet",
  mpcContractId: "v1.signer-prod.testnet",
});

await client.login();
const signer = await client.getSigner();
