Coinbase Staking API

Coinbase Staking API

Programmatic access to Coinbase's best-in-class staking infrastructure and services. 🔵

npm version Current version GitHub contributors GitHub Stars GitHub

Overview

staking-client-library-ts is the Typescript SDK for the Coinbase Staking API 🔵.

The Coinbase Staking API empowers developers to deliver a fully-featured staking experience in their Web2 apps, wallets, or dApps using one common interface across protocols.

A traditional infrastructure-heavy staking integration can take months. Coinbase's Staking API enables onboarding within hours ✨.

Quick Start

Prerequisite: Node 20+

  1. In a fresh directory, run:

    npm install @coinbase/staking-client-library-ts

  2. Copy and paste a code sample from below or any other example into an example.ts file.

  3. Create a new API Key in the portal and paste the API Key name and private key into the example.

  4. Run 🚀

    npx ts-node example.ts

Stake Partial ETH 💠

This code sample helps stake partial ETH (non-multiples of 32 ETH). View the full source here

// examples/ethereum/create-workflow.ts
import { StakingClient } from "@coinbase/staking-client-library-ts";

// Set your api key name and private key here. Get your keys from here: https://portal.cdp.coinbase.com/access/api
const apiKeyName: string = 'your-api-key-name';
const apiPrivateKey: string = 'your-api-private-key';

const client = new StakingClient(apiKeyName, apiPrivateKey);

client.Ethereum.stake('holesky', '0xdb816889F2a7362EF242E5a717dfD5B38Ae849FE', '123')
  .then((workflow) => {
    console.log(JSON.stringify(workflow, null, 2));
  })
  .catch(() => {
    throw new Error('Error running stake action on ethereum');
  });

View Partial ETH Rewards 💰

This code sample helps view rewards for an Ethereum address. View the full source here.

// examples/ethereum/list-rewards/partial-eth.ts
import { StakingClient } from "@coinbase/staking-client-library-ts";

// Set your api key name and private key here. Get your keys from here: https://portal.cdp.coinbase.com/access/api
const apiKeyName: string = 'your-api-key-name';
const apiPrivateKey: string = 'your-api-private-key';

const client = new StakingClient(apiKeyName, apiPrivateKey);

// Defines which address and rewards we want to see
const address: string =
  '0x60c7e246344ae3856cf9abe3a2e258d495fc39e0';
const filter: string = `address='${address}' AND period_end_time > '2024-05-01T00:00:00Z' AND period_end_time < '2024-05-02T00:00:00Z'`;

// Loops through rewards array and prints each reward
var list = async function () {
  const resp = await client.Ethereum.listRewards(filter)
  resp.rewards!.forEach((reward) => {
    console.log(JSON.stringify(reward, null, 2));
  });
}
