Launchpad on Raydium LaunchLab · Solana

The house takes almost nothing and everyone at the table eats.

The dev sets the tax, what it buys and who gets paid. The platform takes 0% on the curve. Every payout epoch is published.

The eggs come in the quote asset, gold, staked SOL, or the token itself. The dev decides.

How it works

Three dials the dev sets. Other launchpads hard-code them.

Of the 21 platforms Raydium lists, only StonkFun pays a transfer tax to holders, with one fixed rule. COOP is the second launchpad on LaunchLab whose tokens pay holders, and the first where the dev chooses the rule.

1

The tax

0 to 3.3% on every transfer, the dev's choice. StonkFun offers 1% or 3%.

2

What it buys

The quote asset, any Jupiter-routable asset such as gold or staked SOL, or the token itself. Or burn it. Or send it to the treasury.

3

Who gets paid, by which rule

Five vetted rules:

  • pro-rata
  • holding-time weighted
  • never-sold bonus
  • balance-weighted lottery
  • threshold

Rules that reward wallet splitting or wash trading are refused. Splitting a wallet never raises its payout.

1 sweep the tax→2 convert it→3 snapshot holders→4 apply the rule→5 pay→6 publish the ledger

Every epoch. Payouts too small to deliver are carried forward and paid when they add up. Nothing is rounded away or kept.

Verified claims

Five things you can check yourself.

Everything on this page comes from a list of claims verified on-chain or against Raydium's docs and API. These are the five strongest, with where to look.

0% platform fee on the curve.

StonkFun charges 1%, pump.fun 0.95%, letsbonk 1.25%. On COOP the platform's curve fee is zero, readable in the platform account.

Proof: the COOP platform account (feeRate 0), and the 0.25 and 0 accounts.

Cheapest curve on Solana.

0.75% all-in with the 0.5% creator fee, 0.50% with 0.25%, 0.25% with 0. Only Raydium's own 0.25% remains. Incumbents: 1.25% (StonkFun, pump.fun), 1.5% (letsbonk).

Proof: the DVTEST dev buy shows the split on-chain, 0.05 SOL in, 0.049625 to the curve (0.25 Raydium + 0.5 creator + 0 platform). DVTEST on Solscan.

Devs are paid by the program, not by a promise.

The 0.5% creator curve fee, the program's cap, accrues to the dev's own on-chain vault and only they can claim it. After graduation, 1.00% per swap on the pool with 0.42 forwarded to the dev, published per token. StonkFun sets the creator fee to 0 and forwards off-chain; its reward-mode creators get nothing.

Proof: the creator fee rate in the platform account; per-token dev forwards in the ledger.

Rules that cannot be gamed by splitting wallets.

Pro-rata, holding-time weighted, never-sold bonus, balance-weighted lottery, threshold. Rules that reward wallet splitting or wash trading are refused. Unit-tested invariant: splitting a wallet never raises its payout.

Proof: the rules documentation, with the invariant tests.

Every epoch is published.

Snapshot, rule output, allocations and transaction signatures go into a ledger. Claim-mode roots let holders verify their own line.

Proof: the first live payout epoch, 2026-09-25, four signatures below.

Also true, and also on-chain: liquidity is permanent by construction (LaunchLab locks or burns 100% of the graduated LP; on COOP, half locked and half burned) and the mint authority is revoked at creation.

The COOP token

COOP, the token, launches on StonkFun.

Reward mode, quoted in STONK, with a 3% tax. Every COOP trade buys STONK for COOP holders.

  • Treasury, not a dump. The dev buy, 20 to 30% of supply, is held as the project treasury under a published never-sell policy.
  • The treasury eats too. It earns its pro-rata share of the STONK payouts like any other holder.
  • Same table, both ways. COOP's tax buys STONK, so StonkFun's token gains when COOP does.

The test token DVTEST ran the whole loop on 2026-09-25: tax swept, converted, a holder paid, the treasury paid, everything signed.
