Steam cartridges, on Solana

Upload a tiny game — HTML, JavaScript, WASM. Stampy bundles it into one cartridge, chunks it across Solana transactions, and gives it a permanent play page that reconstructs the game straight from the chain. Every game launches with its own Pump.fun coin.

Cartridge

Required

Upload your game's files. Stampy bundles the HTML, JavaScript and WASM into one self-contained cartridge, chunks it across Solana transactions, and reconstructs it on a permanent play page — no server hosts it.

An inscription file is required.

Coin

Every game launches with its own Pump.fun coin. Players can trade it while the cartridge lives on-chain forever.
