Before you start

Set up your project and get an API key.
1

Install the SDK

Run the following command to install the SDK:
npm i @crossmint/wallets-sdk
2

Create a wallet

See all supported chains here.
index.ts
import { CrossmintWallets, createCrossmint } from "@crossmint/wallets-sdk";

const crossmint = createCrossmint({
    apiKey: "<your-server-api-key>",
});

const crossmintWallets = CrossmintWallets.from(crossmint);

const wallet = await crossmintWallets.createWallet({
    chain: "<your-chain>",
    signer: {
        type: "<signer-type>",
    },
});

console.log(wallet.address);

​
Launching in Production

For production, the steps are almost identical, but some changes are required:
  1. Create a developer account on the production console
  2. Create a production client API key on the API Keys page with the API scopes users.create, users.read, wallets.read, wallets.create, wallets:transactions.create, wallets:transactions.sign, wallets:balance.read, wallets.fund
  3. Replace your test API key with the production key
