Solana setup.

1 · Privy (embedded wallets)

1. 1
   Create a Privy app

   dashboard.privy.io → new app. Copy the App ID into NEXT_PUBLIC_PRIVY_APP_ID. No app secret is needed, signing happens client-side.
2. 2
   Enable Solana embedded wallets

   In the Privy dashboard enable Embedded wallets → Solana (create on login), and turn on at least one login method (email is easiest).
3. 3
   Allow your origins

   Add http://localhost:3000 and your production domain to Privy's allowed origins, connect fails from unlisted origins.

2 · RPC

• Without config, the app uses the public mainnet RPC, fine for trying things, rate-limited in practice.
• For real use set SOLANA_RPC_URL to a provider like Helius or QuickNode. It's used only server-side by /api/solana/rpc; the key never reaches the client, and the route rejects cross-site callers.

3 · Jupiter

• Swaps and prices use Jupiter's keyless lite API by default (lite-api.jup.ag) via the allowlisted proxy, nothing to configure.
• Override with NEXT_PUBLIC_JUPITER_BASE if you have a paid Jupiter tier.
