Solana Wallets Quickstart

Live Demo | Docs | See all quickstarts

Introduction

Create and interact with Crossmint wallets in Solana. This quickstart uses Crossmint Auth and uses your external wallet (e.g Phantom, Coinbase, etc.) as a signer for that wallet.

Learn how to:

• Create a wallet
• View its balance for SOL and SPL tokens
• Send a transaction
• Add delegated signers to allow third parties to sign transactions on behalf of your wallet
