When it runs
The crank runs at 00:00 and 12:00 UTC, for every coin on the books, in three steps:
| Step | What it does | Minimum |
|---|---|---|
| Sweep | Moves fees waiting on the launch curve into the coin's fee vault. Free to skip when nothing waits. | – |
| Pay out | Splits what's in the vault between your recipients, exactly by their shares, in one transaction. | 0.02 SOL |
| Burn | If the coin has a burn wallet holding enough, buys the coin and burns it. | 0.03 SOL |
Under a minimum, the step waits for the next pass; the Books record that the crank came by and what was waiting.
Who pays for it
Mob pays the network fee for every crank transaction. Paying out is permissionless: pump.fun lets anyone trigger it, and the money can only go to the split's recipients. Mob runs it so you don't have to, but if Mob stopped tomorrow, your split would keep working for anyone who triggers it.
After graduation
When a coin graduates, its trading moves to a PumpSwap pool, and creator fees from that pool collect separately. The crank pays out fees from the launch curve today; collecting fees from the graduated pool is being added.
