Every repository has a family tree. Some have tokens.

Type anything and upstream traces the GitHub repositories it forked from. Project tokens sit on their repos in blue; coins launched here in amber, their creator fees split between the launcher, the repo's people and forks.

    Every repository lives in git. Crypto began in bitcoin/bitcoin; litecoin forked it, dogecoin forked litecoin, and ethereum and solana took the idea further. On Solana, Anza forked the validator and Jito forked it again, Anchor became the way programs are written, pump.fun was built on it — and forks is built on pump.fun: a coin on any repository, its fees going to the people who wrote the code. Blue is a project’s token on Solana; amber is a coin launched here. Tap any point.
