Quickstart

Install

To get started, install the latest version of Stableit SDK.

npm

npm install @stable-io/sdk

yarn

yarn add @stable-io/sdk

Initialize the SDK

import { ViemSigner } from "@stable-io/sdk";
import { privateKeyToAccount } from "viem/accounts";
import StableSDK from "@stable-io/sdk";

const privateKey = process.env.EVM_PRIVATE_KEY;
const account = privateKeyToAccount(privateKey);

const sdk = new StableSDK({
  network: "Testnet",
  signer: new ViemSigner(account),
  rpcUrls: { // optional
    Ethereum: "https://ethereum-sepolia.rpc.subquery.network/public",
  },
});

How to use the SDK

1

Initialize the SDK

Create a Stableit SDK instance by providing a network, signer (e.g. Viem account), and optional RPCs.

2

Find Routes

Call findRoutes(intent) with source/target chains, amount, and addresses to get available transfer routes.

3

Check Funds (optional but recommended)

Use checkHasEnoughFunds(route) to ensure the sender can cover all fees.

4

Execute the Route

Run executeRoute(route) to sign and submit all necessary transactions—either using pre-approval or permit.
