How mycel.lol works

mycel.lol is a launchpad for Solana coins. You launch a coin like on any pad. The difference: its creator fees buy your coin back, and part of them also buys the coins your holders hold.

1 · launching

Launching a coin takes a minute

Connect your wallet. Phantom, Solflare or Backpack.
Name it. A name, a ticker, an image. A description and links if you want.
Sign. Once to prove the wallet is yours, then the launch itself. About 0.012 SOL in network fees, plus your dev buy if you make one.
It's live. Your coin trades on pump.fun like any other, and joins the network.

2 · creator fees

Where the creator fees go

Every 10 minutes, the fees your coin earned are spent like this:

70%buys your coin back

30%buys the coins your holders also hold

100%of what is bought is burned

The 30% goes mostly to the coins you share the most holders with. If your holders hold no other coin of the pad, your coin keeps 100% of its fees for its own buyback. And it works both ways: other coins send part of their fees to buy yours.

3 · what you can count on

Nobody can touch the fees

Locked at launch. The launch sends 100% of your coin's creator fees to its own vault and locks that setting forever. Not you, not us, nobody can change it afterwards.
Real holders only. A wallet counts if it holds at least 0.05% of both coins, for at least an hour. Pools, bonding curves and program accounts never count, and splitting a bag across many wallets gains nothing.
Everything is public. Every buy and every burn is listed with its transaction on the network page.

The vocabulary, in one line each

epoch: The 10-minute cycle. Fees are spent once per epoch.
filament: The link between two coins that share holders. The more they share, the thicker it is.
neighbour: A coin linked to yours by a filament. Your 30% goes to your neighbours.
vault: The wallet that receives your coin's creator fees. Only the network spends from it, only to buy and burn.
burned: Sent out of existence: the supply goes down for good.

for the curiousThe full technical rules

1 · Filaments

epoch: 10 minutes. At each epoch the site reads the holders of every coin launched on the pad.
weight: w(A, B) = Σ min(% of A held, % of B held), over every eligible wallet holding both coins. Measured in percent of supply.
minimum position: A wallet counts only if it holds at least 0.05% of each of the two coins.
minimum time: That position must have been held for at least one hour.
excluded accounts: The bonding curve, liquidity pools, pad accounts and program accounts are never counted as holders.
splitting: Spreading a position across several wallets never increases a weight: the minimum is taken per wallet, and pieces under 0.05% drop out.

2 · Circulation

self: 70% of the fees a coin accrued during the epoch buy that coin back. Those tokens are burned too: nothing bought by the network is ever held.
network: 30% are split between its neighbours in proportion to filament weight: neighbour B receives 30% × w(A, B) / Σ w(A, N).
digestion: Each neighbour's share buys that neighbour's coin. The tokens bought are burned.
isolated coin: A coin with no filament keeps 100% of its fees.

3 · Operation

launch: A coin joins the pad with its creator fees routed 100% to its own vault. That first fee-split update locks the split for good on pump.fun: after it, nobody (the creator, the pad) can redirect those fees.
locked fees: Checked on-chain at every epoch. A coin whose fees are not locked to its vault is cut from the network: it neither sends nor receives.
snapshot: Taken on every 10-minute boundary. Holders are read on-chain; an owner counts only if it is an ordinary wallet (owned by the System Program and on the ed25519 curve). Curves, pools, vaults and every program-derived address are left out, even on a coin nobody has indexed yet.
one hour: A wallet is eligible if it held at least 0.05% of the coin in each of the last 7 snapshots (one hour). It counts for its smallest share over that hour, so buying just before a snapshot adds nothing. If a snapshot is missing, nobody is eligible on that coin until a full hour is back.
collection: Each epoch, the coin's pending creator fees are moved into its vault. The vault keeps 0.005 SOL for rent and transaction fees; everything above is routed.
purchase: One transaction per purchase: buy an exact amount of tokens, burn them, close the token account. All three succeed or none does. The price is capped so that even at 3% slippage the buy cannot spend more than its share.
dust: A purchase under 0.001 SOL is not made; those lamports stay in the vault and are routed again next epoch.
failure: If a purchase fails, its lamports stay in the vault and are routed next epoch. Nothing is redistributed by hand.
ledger: Each epoch publishes the holder snapshot of every coin, its SHA-256 fingerprint, the filaments, and every purchase with its transaction. See network.
