name	web3-thirdweb-siwe
description	Implement and debug wallet connection and authentication in this repo using thirdweb v5 and the SIWE-style flow in `app/hooks/useWalletAuth.ts` and `app/hooks/server_actions.ts`. Use for ConnectButton setup, account state, signature/auth verification, Base/USDC config, and CSP issues with embedded wallet.

Confirm env is set:
- NEXT_PUBLIC_THIRDWEB_CLIENT_ID
- NEXT_PUBLIC_API_URL
- NEXT_PUBLIC_WS_URL
Confirm CSP allows thirdweb embedded wallet frames and network:
- frame-src includes https://embedded-wallet.thirdweb.com
- connect-src allows required hosts
Trace auth flow:
- getAuthPayload(address) → returns { payload, message }
- account.signMessage({ message }) (sign the message string)
- verifySignedPayload({ payload, signature })
- On failure, disconnect wallet and clear attempt ref

For the repo’s exact auth sequence and edge cases: read references/auth-flow.md.
For CSP gotchas (embedded wallet / Turnstile / Tenor): read references/csp-and-headers.md.
