PROTOTYPE — TEST MONEY ONLY. Fiat balances are mock numbers on this device; crypto runs on the Sepolia testnet. Nothing here is real money.
Exchange — demo, mock rates.

Exchange fiat ↔ ETH (demo)

Mock rate: 1 ETH = $4,200.00 / $3,100.00 — a made-up demo rate, NOT a market price. ETH bought here is ETH (demo), a number in this app's mock ledger, kept separate from your real Sepolia wallet balance.

Available: $1,250.00 (test) · Rate: 1 ETH = $4,200.00 (mock)

The fee is always shown before you confirm — never hidden.
