Wallets SDK

A Typescript SDK to interact with Crossmint Wallets. This SDK enables developers to easily create and manage wallets on Solana and EVM chains.

Get a Crossmint client API key from here and add it to your .env file. Make sure your API key has all scopes for Wallet API, and Users.

Installation

``bash
pnpm install @crossmint/wallets-sdk
`

Usage

`ts
import { CrossmintWallets, createCrossmint } from "@crossmint/wallets-sdk";

const crossmint = createCrossmint({
apiKey: "",
experimental_customAuth: {
jwt: "", // required for client-side calls, optional for server-side calls
},
});
const crossmintWallets = CrossmintWallets.from(crossmint);
const wallet = await crossmintWallets.getOrCreateWallet({
chain: "",
signer: {
type: "email",
email: "",
onAuthRequired: async (needsAuth, sendEmailWithOtp, verifyOtp, reject) => {
if (needsAuth) {
await sendEmailWithOtp();
// Prompt the user to check their email for the OTP code.
// Once the user provides the OTP, pass it to verifyOtp(otp).
// NOTE: If using our React/React Native SDK, this is handled automatically by the provider.
}
},
},
});

console.log(wallet.address);

`ts

// EVM
const evmWallet = EVMWallet.from(wallet);
const evmTx = await evmWallet.sendTransaction({ transaction: "" });
