Run your first test draw.

One setup transaction creates your test token and jackpot. Your wallet signs; the app fills in the addresses and prepares the first test round.

Create your test jackpot

Base Sepolia only. Creates 1,000,000 POTTEST tokens in your connected wallet and binds the jackpot to the official randomness wrapper. No real-money token, liquidity pool or funded prize is created.

Use Quicknode: select Base and Sepolia, then enter this same wallet address and choose the free base drip. Quicknode says no mainnet balance, paid account or X post is required; verification and claim limits still apply. Your balance refreshes when you return here. Mainnet ETH does not pay for this test.

Testnet deployment · test assets only

This flow deploys on Base Sepolia. Production deployment is a separate reviewed release. No live mainnet funds or ticket sales are activated here.

I reviewed the network, addresses and parameters. These deployments consume test ETH for gas. I understand the contracts are unaudited.

What this deploys

Immutable prize rules and token accounting.
A dedicated Chainlink direct-funded randomness adapter.
Separate ETH reserves for each draw’s costs and fixed execution rewards.
Permissionless request and settlement calls; no operator selects winners.
Pull-based prize, reward and refund claims.

Optional public executor

The downloadable package includes a one-pass executor and repeat-run instructions. It can run on your host or an independent operator’s host. The contract pays successful executors; it does not guarantee someone will send a transaction.

Bankr creates a liquidity pool and creator fee routing. Launch it explicitly on Base and publish the treasury and fee allocation. A token launch does not fund the prize reserve automatically.
