ROM-20
Real games on Solana

Every byte
on chain.
Press play.

Stores pull games. Platforms shut down. ROM-20 writes real games to Solana, block by block, where no one can pull them. Trade the coin to write the game. At 100 % it unlocks. Burn the coin to own a numbered copy.

Why ROM-20

Games die.
Even the ones you paid for.

A license runs out and the store pulls the game. A publisher switches it off. A whole platform closes. Each time, players lose games they paid for.

Game over

ROM-20

A store can pull a game.
No one can pull a block.

ROM-20 writes the game itself to Solana, byte by byte. When the last block lands, the game is part of the chain. There is no store to pull it from and no switch to turn it off.

01 / Trade to unlock

Trades write
the game.

Each game has its own coin on pump.fun. The creator of the coin is a pot on chain, not a person. Every trade pays fees into the pot, and the pot writes the next blocks of the game.

  1. 1 SOLtraded on the coin
  2. 0.003 SOLof fees into the pot
  3. 600blocks written
  4. 2.3 MBof game on chain

Rough figures. At 100 % the game unlocks for everyone.

02 / Checked in your browser

Every page
is checked.

A game goes on chain in blocks of 3,840 bytes, one block per transaction. One Merkle root seals the full game. Your browser checks each page against that root before the game starts.
