Pump Karts — Project Overview

Pump Karts

Project Overview

A free-to-play 3D kart racing and battle game on Solana. Playable in the browser today.

Abstract

Pump Karts is a real-time, free-to-play 3D kart game that runs in the browser: no download, and no wallet needed to play. Races and battles are resolved by an authoritative server. $KARTS, the game's Solana token, powers ranked play, cosmetics and the in-game economy. Pump Karts is live and playable today.

The product

Pump Karts is server-authoritative. Positions, items and results are resolved on the server, so every player sees the same race and the result comes from the server, not from a browser. The roster is an original cast of drivers built for the game, all free to play, across four arenas: Pump Park and Pump Galaxy for racing, Neon City and Pump Casino for battles. It runs on desktop and mobile, with servers in Europe and the US.

Game modes

GoKarts. Eight-kart circuit racing with drifting, turbo boosts and weapon pickups. Casual lobbies stay together as a playlist and vote on the next map.
Ranked. GoKarts races for players holding 1,000 $KARTS, feeding a daily leaderboard.
Rug Rumble. A weapons-based battle arena for up to fifteen karts. The most knockouts when the clock runs out wins.
1v1 Duels. Free best-of-three races. Post an open challenge for anyone to accept, or invite a friend with a match ID.
Private rooms and solo. Race or battle with friends by match ID, or practice against bots.

Progression and retention

Levels and profiles. Online play earns XP on your wallet. Set levels unlock kart paints, and level 50 unlocks the Genesis kart.
Daily and weekly quests for holders, with a weekly points leaderboard.
A daily login streak on a seven-day reward cycle, a friends list, and referral links.
A sticker maker that lets the community generate character stickers as organic content.

Token and economy

$KARTS is the game's token. Holding it unlocks ranked play, quests and free Lucky Spins. Spending it buys cosmetics.

Cosmetics. Kart paints and kart skins drop from the Lucky Spin and trade player to player on the in-game market, where the seller receives 100% of the price in $KARTS. Cosmetics are visual only and give no gameplay advantage.
Custom Studio. Players design their own kart paint, part by part. Unlocks are priced in USD and paid in $KARTS.
NITRO. The in-game soft currency, earned by playing. It has no cash value and cannot be withdrawn. It pays for extra Lucky Spins, boosts and mystery boxes. $KARTS can be converted into NITRO, and the $KARTS spent that way is burned.
Verifiable. Market trades and burns settle on-chain, and a public stats page reports the total $KARTS burned.
