Frontend

Next.js routes, stores, and which screens are live on Solana.

Backend-Solana is the product UI.

Live screens

Path	Status
/earn, /earn/[id]	Live — seven pools
/margin	Live — Perps long/short
/trade/spot	Live — Jupiter
/one-click	Live — Farm
/portfolio	Live — lender + trader
Faucet modal	Live — fork only

Navbar still shows labels inherited from the multi-chain app. On this build, Perps is /margin and Farm is /one-click.

Data path

1. Wallet adapter or Privy embedded wallet
2. Anchor Program from idl/vanna_lending.json
3. Account reads (reserve, margin, Lite PDAs)
4. Pyth Hermes or fork price refresh
5. Jupiter quote proxy (/api/jupiter/quote)
6. simulateAndSend — simulate, then submit

History uses /api/solana/history and /api/solana/spot-history (RPC / Alchemy-style parsing on the fork).

Limitations to document honestly

• P&L and entry price for perps are derived from vaults, debt, and history grouping — not a dedicated position account
• Hosted RPC may expose fork cheatcodes; treat the demo as a trusted-tester sandbox
• Token-2022 fees can make “exact” UI numbers differ from vault deltas by a few units
