app.fade.finance runs every flow end to end against the program on Solana devnet. The USDC is a test token with no value, and the SOL is devnet SOL.

​
What you need

  1. A Solana wallet. Phantom, Solflare, Backpack and other Wallet Standard wallets work, as do mobile wallets over WalletConnect. The app sends everything through its own devnet connection, so your wallet’s network setting does not matter.
  2. Test USDC and a little devnet SOL. Click the faucet button in the app. It sends 1 000 test USDC per claim, and adds a little devnet SOL when the wallet has almost none (at most once a day per wallet). Claims are limited to one every 5 minutes per wallet and per IP address. If you need more SOL, use faucet.solana.com.

The demos

Checkout win-back

Pay for a cart and take a fixed-odds chance to have the whole order paid back.

Swap win-back

A swap whose ticket rides in the same transaction. The swap leg is simulated on devnet; the payout is real.

Jackpot

A five-outcome paytable: something back most of the time, a rare 10×.

Safety checks

Paytables the program refuses before anything moves: one that overpays, one too large for the pool.
Each demo shows the paytable before you sign, simulates the transaction against the program first (so a refusal is shown in the program’s own words and costs nothing), then hands the opened wager to the public keeper. You sign once and watch the wager move through requested, fulfilled and settled. Every step links to the Solana explorer. In these demos your wallet is its own app: it signs as the integrator, pays the rent, stakes from its own USDC account and is the beneficiary, at a zero app fee. A real integration usually splits those roles. See Integration overview.

​
The pool dashboard

app.fade.finance/pool shows the devnet pool: its assets, the share price, the next strike, your position, the providers and recent activity. You can deposit test USDC and withdraw from there. See Dashboard.

​
Devnet is not the protocol defaults

Devnet runs with two parameters lowered so the demos are quick and cheap: a minimum stake of 0.10 USDC and epochs of 120 seconds. The protocol defaults are listed with the devnet values on Devnet addresses and parameters.
Prize-linked payouts are subject to local gaming and promotion law. The devnet demos use test tokens with no value.
