Racco Racing

Four tracks, three laps, one clock

Each race is three laps against the clock. The timer starts when the countdown ends and every lap is timed on its own, so one bad corner only costs you that lap. Leave the road and the car slows on the grass; go wide enough and a barrier pushes you back. Each track has gold, silver and bronze targets that we set for practice; they are goals, not records anyone has driven.

The garage changes the look, never the lap

In the garage you choose a paint colour, one of four body kits (stock hatch, street wide, rally raised or night wedge), wheels, a roof accessory, a stripe and a race number from 0 to 99. The car on the club screen and the car on the track are both drawn from those settings, so what you build is what you drive.

Handling is identical for every combination. A wide body does not grip better and a spoiler does not add speed. That keeps the lap book fair: when two wallets record a time on the same track, the difference is the driving. Your settings are saved in this browser. When you record a lap, a fingerprint of the car (a keccak-256 hash of its settings) goes with it, so anyone can see which build set the time.

Your ghost is your toughest rival

The fastest lap you drive on a track becomes your ghost: a see-through car that replays that exact line next to you on every lap of your next race. Beat it and the ghost is replaced by the new lap. Ghosts are stored in this browser only and are never uploaded.

Your driver profile adds up what you have done here: races finished, laps, distance on a toy scale, your favourite track, the best lap and medal on each track, and six badges such as Full card (a lap on every track) and Ghost buster (beat your own ghost). You can give your driver a name. None of it leaves your device unless you record a lap.

A lap book anyone can read on Robinhood Chain

The lap book is a small contract, RaccoLapBook. A wallet sends its own lap: track number, time in milliseconds, the car fingerprint and a fingerprint of the lap's inputs. The contract keeps one best lap per wallet per track, accepts only laps between 5 seconds and 10 minutes, and only replaces a time with a faster one. It has no owner, no admin key, no fee and no upgrade path, and it cannot hold funds.

The contract cannot watch your race, so every time on the leaderboard is self-reported and labelled that way. A recorded lap proves that a wallet claimed that time at that block, not that it was driven. The leaderboard on this site reads the contract directly. Recording costs a little ETH for gas on Robinhood Chain; racing costs nothing.

How to find a faster lap

Most time is lost before a corner, not in it. Lift or brake while the car is still straight, turn in once the speed is down, and get back on the gas as the road opens. The car keeps its grip at low speed and loses a little bite near the top end, so a slow entry and a fast exit beats a brave entry almost every time.

Stay off the grass: the car sheds speed hard the moment a wheel leaves the road, and a wide moment past the run-off ends at the barrier. Watch the minimap for the next bend, use your ghost as a pace car, and press Watch a demo lap to see how the club autopilot takes each track. Demo laps are for learning only and cannot be recorded.

What reaches the chain, and what never does

Racing, the garage, your ghosts and your profile never leave this browser. Nothing is uploaded to a server and there is no account to create. When you press Record my lap, your wallet shows one transaction with four values: the track number, the lap time in milliseconds, the car fingerprint and the ghost fingerprint. Your address is public once it sends that transaction, like any transaction on Robinhood Chain.

The site never asks for a seed phrase or a private key and never moves funds. Connecting a wallet only shares your address. Practice entries are signed messages that cost nothing and stay in your browser until the lap book contract is live.
