Wallets Quickstart

Live Demo | Docs | See all quickstarts

Introduction

Create and interact with Crossmint wallets. This quickstart uses Crossmint Auth and uses your email as a signer for that wallet.

Learn how to:

• Create a wallet
• View its balance for SOL and SPL tokens
• Send USDC or SOL to another wallet
• Add permissions to allow third parties to sign transactions on behalf of your wallet

Deploy

Easily deploy the template to Vercel with the button below. You will need to set the required environment variables in the Vercel dashboard.
