A market built around the writers
Callbook brings pump.fun callout writers into one discoverable board. Each profile shows the author's recorded payouts, callout activity, key supply and current key quote. The board is a view of published data, not a promise about the next trade.
There are two separate ways to participate: buy an author's keys, or place a daily prediction on that author. Holding a key does not automatically place a prediction, and a prediction does not buy a key.
Choose your path
| Keys | Daily Call | |
|---|---|---|
| What you hold | A position in a caller's key supply | A prediction for one round |
| Pricing | A quadratic supply curve | Your chosen stake |
| Exit | Sell at a fresh curve quote | Wait for settlement |
| Rewards | Eligible trading fee and round rake shares | A share of the pot if your caller places |
