Web3 (thirdweb v5) + SIWE Auth (Stacked Poker)

Repo entry points

• thirdweb client + wallets: app/thirdwebclient.ts
• Provider wiring: app/providers.tsx
• Connect UI: app/components/WalletButton.tsx
• Auth orchestration: app/hooks/useWalletAuth.ts, app/contexts/AuthContext.tsx
• Backend calls: app/hooks/server_actions.ts
• Security headers / embedded wallet frames: next.config.js

Documentation sources (don’t paste full docs)

• thirdweb LLM docs (per repo rules): https://portal.thirdweb.com/llms.txt
• thirdweb full LLM docs: https://portal.thirdweb.com/llms-full.txt
• thirdweb API docs: https://api.thirdweb.com/llms.txt
• Use the thirdweb-api MCP server (see .cursor/mcp.json) for up-to-date references.

Debug workflow (common issues)

1. Confirm env is set:
   • NEXT_PUBLIC_THIRDWEB_CLIENT_ID
   • NEXT_PUBLIC_API_URL
   • NEXT_PUBLIC_WS_URL
2. Confirm CSP allows thirdweb embedded wallet frames and network:
   • frame-src includes https://embedded-wallet.thirdweb.com
   • connect-src allows required hosts
3. 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

Mini App notes (Coinbase Wallet / Base)

• Use ConnectButton or ConnectEmbed for wallet UI. ConnectEmbed is the same UI as the modal, but inline, which is useful for an embedded sign-in screen in a Mini App.
• Configure wallets explicitly via the wallets prop; include inAppWallet() and any target wallets (ex: createWallet("com.coinbase.wallet")).
• The Connect UI supports 500+ wallets and in-app wallets, so keep a short, curated list for Mini App UX.
• The Connect UI can optionally include Auth (SIWE-style), which can be wired to your existing server endpoints.
• Inference: WebViews typically don’t have browser extensions, so don’t rely on auto-detected EIP-6963 extensions; prefer explicit wallet configuration.
