## What it is
Coinbase Wallet SDK is a TypeScript library that lets decentralized applications (dapps) connect users to Coinbase Wallet, including the Smart Wallet, mobile apps, and browser extension. It provides a web3 provider implementing standard Ethereum JSON-RPC methods like eth_requestAccounts, personal_sign, and wallet_sendCalls.

## Use cases
- connect a dapp to Coinbase Wallet
- let users sign in to my web3 app with their wallet
- add wallet connection to an ethereum dapp
- send ethereum transactions from a browser dapp
- integrate Coinbase Smart Wallet into my app
- request user accounts and signatures via a web3 provider
- support QR code wallet connection on desktop and deeplink on mobile

## When to choose
- you are building an Ethereum/EVM dapp and want Coinbase Wallet support
- you want a maintained SDK with Smart Wallet, mobile, and extension connectivity
- you need a standard EIP-1193 web3 provider in a JavaScript/TypeScript app

## When to avoid
- you need multi-wallet support across many providers (consider WalletConnect or a connector framework)
- your app is not blockchain-related
- you target non-EVM chains only
