How the receipt is made
Nothing is estimated from a fee table. Every fee is read off the trades your wallet actually made.
Measuring tax
STONK (stonkfun.xyz) launches on Raydium LaunchLab. Every trade on a launch's bonding curve pays 1% to the platform and 0.25% to Raydium; after graduation, every trade on the pool pays a 0.25% pool fee to the platform's locked liquidity and a 1% creator fee. Reward coins add a 1% or 3% transfer tax on every transfer. Bot and router fees are not STONK's and are not counted.
We read your wallet's transactions, find the ones that touched a STONK curve or pool, and take the fee amounts from what the programs actually moved: the platform fee lands in a fee vault in the same instruction, the rest follows from the pool's own rates and rounding. The trader is whoever owned the token accounts, not whoever paid for the transaction, so bots and routers do not confuse it.
- Your wallet history comes from the chain: the last 90 days, at most 5,000 transactions. The receipt says which window it covered.
- Each trade is priced in dollars at the hour it happened: the paired asset (SOL, USDC, STONK, an xStock…) from public price history, the launched coin through the trade itself.
- Everything is one number: platform fee, Raydium's share, pool and creator fees, transfer tax.
- Trades paired with an asset that has no price history count as $0 and are listed as such on the receipt.
Checked against the programs' own figures: in 60 recent trades our fee split matched LaunchLab's TradeEvent to the lamport on all 30 curve trades, and the swap amounts matched the CPMM event on all 30 pool trades.
The rebate
Trades of STAX pay 5% in tax: 2.8% goes to the treasury, 1.2% runs the project, 1% is the launchpad's share. The treasury pays rebates in SOL.
| Rate | Treasury ÷ (2 × the tax paid by everyone who connected), capped at 20% of what you paid. |
|---|---|
| Your claim | Your tax × today's rate, paid in SOL at the Pyth price, at most 5% of the treasury per claim. |
| Holding | You must hold STAX in the wallet that claims, and a claim can never be worth more than the STAX you hold at that moment. |
| How often | One receipt per wallet per day. New tax since your last claim earns a new rebate. |
| Who | Only wallets that connect. Nobody is on a list in advance. |
The rate is the same for everyone at the same moment and always visible on the front page. The treasury can never promise more than it holds: the sum of everything claimable is at most half of it.
What this is not
It is not a refund. Nobody gets their tax back in full, and the rate falls as more wallets connect. STAX is a token with a tax; the rebate is a mechanical use of that tax, not income, yield or a promise of any amount.
