Mechanics

The catalogue, the waterfall, the ceiling, and what runs on chain today.


How mechanics run#

A mechanic is not a program on the token. It is a rule the vault follows when it splits a launch's creator fees in a fee round. The launcher stacks mechanics in order and signs the order; each round, the vault walks the stack top to bottom, each mechanic claiming its share of what is left. Nothing goes to the launcher — HIRE's rule — so the whole creator fee works for the coin.

a round's pot (after the EVYN burn on an EVYN pair)
  ↓
mechanic 1  takes its share
mechanic 2  takes its share of the rest
mechanic 3  …
  ↓
whatever is left stays in the vault (recorded as held)

The stack as a whole may claim at most 80% of a round; the launch flow refuses a stack above it. The arithmetic is shown with your own numbers before you sign.

The catalogue#

Each mechanic has a fixed share and a fixed configuration in this version. Four of them act on chain today; the rest reserve their share in the vault until their action ships, so a launcher who picks them is holding a place, not getting a payout yet.

What each running mechanic does in a round#

MechanicOn chain
BuybackSpends its share buying the coin back on its own curve (or pool), from the vault wallet.
Auto burnBurns every coin the buyback just bought. Supply only goes down.
Holder rewardsPays its share to the largest holders pro rata to their balance, in the quote (SOL or EVYN). Payouts under 10,000 base units are skipped — they would cost more in rent than they pay.
LotteryPays its whole share to one holder, drawn weighted by balance.
Revenue sharePays its share to the launcher's wallet.
Anti-snipe, Dynamic fee, Transfer rules, Privacy rulesTake no share. pump.fun's curve sets the trading rules, so these are declarations on the terms today, not enforcement.
Access rulesIs the holder gate: /api/launches/:id/gate answers from the chain.

Who counts as a holder#

The round reads the coin's twenty largest token accounts from the RPC, leaves out the bonding curve itself, and splits by balance. A coin with more than twenty holders pays its twenty largest. A fuller index is on the roadmap; the figures in every round are published on the launch page either way.
