Questions.
Short answers. The exact rules are on How it works.
What is the pulse?
A score from 0 to 100 taken every 15 minutes for the first day, then hourly up to day 7. Among wallets that held at least 0.01% of supply at the previous beat, it is the share that still holds at least half of their balance, weighted by balance and capped at 1% per wallet so a few large holders cannot decide alone.
What happens when the pulse drops?
Under 60 on two beats in a row, the slice in play burns, at most one slice per 30 minutes. One beat under 30 is a flatline: every slice left burns at once.
And when it stays high?
At 85 or more on 8 beats in a row, the slice in play is released to the dev and the next one comes into play.
How is the first slice decided so fast?
At the second beat, 30 minutes in, T1 is decided no matter what: burned under 70, released otherwise.
Can the dev keep the reserved bag anyway?
Only the slices the pulse releases. Selling reserved tokens, or more than 25% of the free part before 24 hours, burns every slice left. Slices still undecided at day 7 burn too.
Can the dev stop a burn?
Only by advancing a slice's nonce before the pulse calls it, and that shows on the coin page as a cancelled slice, in red, with the reason. Selling the tokens behind a burn also shows as cancelled. Both are public.
Who counts as a holder?
Every wallet, snipers included. The dev wallet, the pool and program accounts do not. The same history always gives the same state, to the block.
Does Pulse hold funds or take fees?
No. There is no treasury and no site wallet. Pulse takes 0%. Trading fees are pump.fun's own, unchanged.
Is there a bundle at launch?
No. The creation and the dev buy are one transaction signed by the dev alone. Nobody else buys in block 0 through Pulse.
What can the site do with my wallet?
Nothing on its own. It prepares transactions, your wallet shows and signs them, and the server checks every signed transaction byte for byte against what it prepared. No key ever reaches the server.
Is a high pulse a buy signal?
No. The pulse says how many holders stayed, nothing about price. Nothing on Pulse is a promise that a coin will go up.
