Platform share & buyback

The platform keeps 20% of every sweep. It is the only income there is: no launch fee, no fee on payouts, no spread. This page says what that share pays for and where it can go.

The share

Each token stores the platform share in force when it was launched, and every sweep of that token uses it. The default is 20%. The operator can change the setting for future launches, between 0% and 50%, but a change never reaches a token that already exists: the terms a launcher saw are the terms that apply.

Precisely, the platform receives what remains of a sweep after the recipients are credited, which is its share plus a few lamports of rounding dust. The arithmetic is on Recipients & shares.

The platform’s books

The platform’s money sits in the same treasury as everyone else’s, so it is kept in its own ledger. Every row adds to or takes from the platform’s available balance, and nothing is ever edited in place.

EntryDirectionWhen
shareInEach confirmed sweep: the platform’s part, rounding dust included
network_feeOutThe network fee of every sweep, payout, buy and burn, including transactions that failed, because a failed transaction still pays its fee
rentOut, or In for a refundThe rent-exempt minimum each creator address has to keep, paid once per token and re-set when Solana changes the minimum (a lower minimum comes back as a refund), and the treasury’s token account the first time it buys a token. Booked only for sweeps and buys that confirmed. See the rent reserve
buybackOutSOL moved into buy and burn of the platform token
withdrawalOutThe operator taking the platform’s money out of the treasury, from the console. Booked only once the transfer has confirmed on chain
depositInThe operator adding SOL to the treasury, for example to fund fees

The platform’s available balance appears on the proof page next to what is owed to recipients, so a withdrawal that ate into recipients’ money would show there as a shortfall.

Withdrawals

The operator takes the platform’s share out with a withdrawal from the console, a plain transfer from the treasury carrying a platform:<id> memo. The console refuses an amount above either of two ceilings, both read at the moment of the request: the platform’s available balance, and what the treasury holds beyond its reserve and everything it owes, payouts on their way and pending burns included. The destination has to pass the same wallet check as a claim. Only one withdrawal can be in flight at a time, and it enters the books once the chain confirms it, so the platform ledger never shows money leaving that did not.

What the share pays for

  • The network fee of every sweep, and the rent reserve of each creator address: paid once, and adjusted only when Solana changes its rent minimum.
  • The network fee of every payout, so a recipient receives the full amount they claimed.
  • The network fees of every buy and burn, so the SOL of a burn order goes into the buy whole.
  • The treasury reserve of 0.05 SOL, which payouts never dip into, so the treasury can always afford the next sweep.
  • Running the service: the RPC, the database, the IPFS pinning, the hosting.

Buyback

When the platform token exists, part of the platform’s share can be spent buying it and burning it, using the same machinery as a recipient on Burn. It is off by default and takes two things to turn on: the operator enabling it, and the platform token’s address being published in the site header.

  1. Each run of the burn job looks at the platform shares booked since its previous run, takes 50% of them by default, books that as a buyback and turns it into a burn order for the platform token. It never takes more than the platform’s available balance, and it first checks on chain that the published address is a token mint; if it is not, nothing is ordered.
  2. Once the orders reach 0.02 SOL, the treasury buys the platform token with that SOL through Jupiter and burns exactly the amount the swap delivered.
  3. Both transactions are in the ledger as a burn with source platform, next to the recipients’ burns.
