how it works

tl;dr

ScalpRunner500x is a playable markets game. There is no house. Every jump opens a real leveraged ETH/USD perpetual long on Avantis (a perps protocol on Base). When you pull the chute or get liquidated, the position settles on-chain and PnL lands in your wallet.

• Non-custodial. Your USDC sits in your own embedded wallet (provisioned by Privy). You can withdraw any amount to any address, anytime. We never touch your principal.
• No house edge. Payouts come from Avantis’s LP pool, not from us. The only thing we charge is a 2.5% open fee on the wager.
• On-chain, verifiable. Every open and close is a real transaction on Base. You can audit your full history on basescan.org.

what is a playable market?

A “playable market” means the underlying instrument is a real, liquid market — not a simulated random number generator or a casino-style RNG. ScalpRunner500x wraps a perpetual futures contract on ETH/USD inside arcade controls. The price you see in the game is the real ETH price feed Avantis uses (sourced from Pyth). Your “wager” is collateral. Your “leverage” is the position multiplier. Your PnL is the actual realized PnL of the perp at your exit price.

You aren’t betting against the operator. You’re trading a leveraged position whose payout comes from a public liquidity pool that does ten-figure monthly volume. That’s the difference between a casino game and a playable market — and it’s why your size doesn’t spook us. Wager what you want.

the round, step by step

1. Pick wager & leverage. Wager is the USDC you risk on this round. Leverage is 75×–500×.
2. Jump. The game opens a long ETH/USD perp on Avantis sized at wager × leverage. The runner takes off; the boost meter shows your unrealized PnL in real time.
3. Pull chute to close at market — profit or loss settles to your wallet in USDC. Or get liquidated: if the price moves enough against you to wipe your collateral, the position auto-closes and you forfeit the wager. At 500× that’s a ~0.2% adverse move. At 100× it’s ~1%. You can see the liquidation price in the game.
4. Repeat. Open another round whenever you want. Your history (last 5) is on the strip; full history is on the unified leaderboard at hiscore.me.

fees

• 2.5% open fee on the wager — goes to the operator treasury. This is the only fee we charge.
• 2.5% Avantis profit fee — charged by Avantis on profitable closes only. This is the protocol fee, not ours.
• Gas — you pay Base network gas in ETH for every open + close. That’s why the wallet menu prompts you to keep ~0.0005 ETH on hand.

Losses do not pay anything to us beyond the open fee. There is no “house wins more than it loses” mechanic baked in — a losing trade pays Avantis’s LPs, not us.

verify the treasury yourself

The 2.5% open fee sweeps to the operator treasury wallet immediately after each open. The address is public:

0xa660a38f40a519f2e351cc9a5ca2f5fee1a9be0d (basescan)

Pick any open transaction from a SR trader on basescan and you’ll see two USDC transfers: collateral to the Avantis vault, and the 2.5% fee to the treasury above. Nothing else flows to us — that’s the entire revenue side of the product.

your wallet, your keys

When you log in, Privy provisions an embedded EVM wallet for your account. The keys live in a TEE (trusted execution environment) on Privy’s infrastructure — we never see them. You grant the backend a scoped session signer so it can submit your trade transactions to Avantis on your behalf. You can revoke this at any time from your Privy account.

To withdraw: open the wallet pill in the topbar → pick USDC or ETH → paste a destination address → sign. The transaction is sent directly from your embedded wallet to your target address on Base. We are not in the path. There is no minimum, no waiting period, no manual review.

risks (read this)

• Leverage amplifies losses. At 500×, a 0.2% adverse move liquidates you. You can lose your entire wager on a single round.
• This is a perps product. Not a savings product, not yield, not investment advice. Wager only what you can afford to lose.
• Smart contract risk. Avantis, USDC, Base, and the underlying contracts can have bugs or be exploited. Pyth oracle outages can cause unexpected liquidations.
