TypeScript SDK: Wallet Adapter (React)

Purpose

Guide wallet connection and frontend transaction submission in React using @aptos-labs/wallet-adapter-react. End users sign transactions via their browser wallet (Petra, Nightly, etc.) — never via raw private keys.

ALWAYS

1. Use @aptos-labs/wallet-adapter-react for frontend wallet integration — this is the standard React adapter.
2. Wrap your app root with AptosWalletAdapterProvider — all useWallet() calls require this context.
3. Use useWallet() hook to access wallet functions in React components.
4. Use the wallet adapter's signAndSubmitTransaction (from useWallet()) in frontend — NOT the SDK's direct aptos.signAndSubmitTransaction.
5. Always call aptos.waitForTransaction({ transactionHash }) after submit — the wallet returns when the tx is accepted, not committed.
