How Heartbeat works

1. 1

   Hold

   Hold at least about 0.2 SOL worth of $BEAT. Buy whenever you like: your own 30-minute clock starts the moment you hold the minimum.

2. 2

   Your own clock

   Every wallet is paid once per 30 minutes of its own continuous holding (30, 60, 90 min…). Joined 5 minutes before or after anyone else? Doesn't matter. Paid in the first payout batch after your mark (batches run every ~1.5–2.5 min, timing randomised).

3. 3

   Fees become the pool

   Every 30 minutes the bot claims creator fees (0.30–0.95% of trading volume on pump.fun) into the payable pool. No volume, no pool.

4. 4

   Climb every round

   Your multiplier follows your rounds held (30-minute payout rounds kept without selling) and is higher every single round: about ×1.43 after one round held, ×2.73 after 11, ×5.8 after 99, with no cap. Your multiplier rises every round with no cap, so your share of each payout keeps growing the longer you hold. SOL payouts follow trading volume — quiet periods can mean smaller rounds. A new wallet starts at 0 rounds held and is not paid at anyone else's multiplier. Your share also scales with your token balance. Sell, even a small amount, and the wallet is permanently excluded from payouts.

5. 5

   SOL lands in your wallet

   No claim button. Each batch sends SOL straight to the wallets that reached their mark.

How each payout is calculated

1. Your clock. A wallet's k-th payout is due at hold_start + k × 30 min (k = 1, 2, 3…), where hold_start is when it began holding the minimum without interruption. Moving all tokens out resets hold_start and k; a sale ends eligibility for good.
2. Batches. A payout batch runs every 90–150 s (randomised). It pays every wallet whose due time has passed.
3. Amount. payout = floor(payable pool × weight ÷ total weight), where weight = token balance × multiplier and multiplier(n) = 1 + 0.5·ln(n) + 0.08·(n−1)^0.75, n = rounds held + 1, with no cap. Two wallets with the same multiplier split by balance (a wallet with 20M tokens gets 20× the share of a wallet with 1M). The multiplier raises your share compared with wallets that hold the same amount for fewer rounds. Your multiplier rises every round with no cap, so your share of each payout keeps growing the longer you hold. SOL payouts follow trading volume — quiet periods can mean smaller rounds.
4. Qualifying, and the rollover. A wallet qualifies in a round only after it has held for its own full 30 minutes. A wallet that does not qualify yet is not paid and loses nothing: its would-be share (pool × its weight ÷ total weight of all holders) stays in the pool and rolls over into the next round, where qualifying wallets share it. Payouts + rollover always add up to the pool exactly (whole lamports; the rounding remainder rolls over too).
5. Linked wallets (demo rule). Wallets that look related, for example funded from the same source or created together, are treated as one group: the group's combined payout weight is capped at its largest single wallet. The share that the cap removes is not given to anyone else; it rolls over into the next round. This is an automatic rule applied to patterns, not a judgement about any person, and it is simulated in this demo.
6. Selling. Any sale, even 1% of a wallet's tokens, permanently excludes that wallet from payouts. The pending share it would have received is forfeited and rolls over into the next round; its balance no longer counts; buying again or moving tokens back does not restore it, and no new 30-minute clock starts. Earnings it already received stay in its history. Only the selling wallet is affected (other wallets in a linked group are not). Banned wallets are listed, with the share each sold of its own holding, on the Banned wallets page.
7. Always solvent. A round pays at most the pool. The pool is topped up by the 30-minute fee checkpoint; total paid can never exceed what was claimed.
8. Cumulative counter. The total paid out is the sum of all batch totals, stored by the server and only ever increasing.

Deviation from the product spec: the spec splits one pool equally among everyone at a single snapshot. Here each wallet is paid on its own 30-minute clock, in proportion to its token balance × rounds-held multiplier, and shares of wallets that are not qualified yet roll over. Demo data: the clock runs 10× faster than real time here.

What funds the pool

The creator fee on pump.fun depends on where the coin trades. These are the bands from the product spec (not re-verified for this demo):

Weights use an escalating, uncapped rounds-held curve: multiplier(n) = 1 + 0.5·ln(n) + 0.08·(n−1)^0.75 for payout round n = rounds held + 1 (no cap, strictly higher every round), with weight = token balance × multiplier and share = pool × weight ÷ total weight. Multipliers and balances only decide how SOL is split between holders; they never create it.
