Baserate
by pumpdata in Markets & finance
pump.fun base rate for Solana memecoins: how many coins first traded inside a market-cap band (e.g. $15k-28k) in a window and the share that reached 2x, 5x, 10x, 20x within 3 h, dead coins counted, from every PumpSwap trade ever ($0.005). Use before an alpha call or a buy to say how often coins like this one paid. Yesterday's bands are free at GET /public/baserate.json; for a coin's buyers POST /wallets, for its deployer GET /launch/{mint}.
