The presets
A preset is one Meteora Dynamic Bonding Curve config, created once by Minnowpad as the launch partner. A coin launched from it follows that config: nobody, including us, can change its terms for one coin.
| Term | Fair | Builder |
|---|---|---|
| Anti-sniper fee on buys | 50% falling to 1% over 60 s | 50% falling to 1% over 60 s |
| Creator's first buy at minimum fee | No | No |
| Curve opening | Steep: little liquidity at low prices | Same |
| Dynamic fee (volatility) | On | On |
| Supply reserved for the creator | 0% | 0% |
| Token authorities | Revoked (immutable) | Revoked (immutable) |
| Creator's share of trading fees | 0% | 50% |
| Graduated liquidity | 100% locked for the platform | 50% locked for the platform, 50% locked for the creator |
| Pool fee after graduation | 3% decaying to 0.25% as the price rises | Same |
| Graduation | About 116 SOL raised, then a Meteora DAMM v2 pool | Same |
The creator's own first buy pays the anti-sniper fee like everyone. A 1 SOL buy in the very first second leaves about 0.5 SOL on the curve. Buy after a minute to pay the floor fee.
The curve
The presets use a custom Dynamic Bonding Curve with 16 liquidity weights that rise from 0.25 to 4. Liquidity is thin at low prices and thicker at high prices, so a buyer who takes a big share of the supply pushes the price up faster. We measured it on the real program, fees excluded: buying 0.1% of the supply costs 0.030 SOL on both our curve and an equal-liquidity curve with the same start and graduation market caps; buying 5% costs 1.95 SOL versus 1.57 SOL (+24%); 10% costs 4.56 SOL versus 3.31 SOL (+38%); 20% costs 11.68 SOL versus 7.36 SOL (+59%). Graduation takes about 116 SOL instead of about 86 SOL on the flat curve.
Block 0
A creator can bundle their own first buy into the launch transaction. It pays the full anti-sniper fee plus a 5% premium sent to the platform wallet in the same transaction. Without block 0 the creator buys later from the coin page, like anyone, with no extra charge. This does not stop other people from buying in block 0 with their own transactions: they pay the same 50% fee.
The Fair score
Paste the address of any coin launched on the Dynamic Bonding Curve, including Jupiter Studio launches. We read the pool and its config from the chain and check six things: the anti-sniper fee, whether the creator's first buy gets a discount, supply reserved for insiders, whether the token can be changed or minted, whether graduated liquidity can be withdrawn, and the creator's share of fees. Each line shows the real numbers.
The score reads the rules a coin was launched with. It does not look at wallets:
- Whether the creator or friends bought in the first block through several wallets
- How concentrated the holders are
- Whether the team's earlier coins were rugs
- Anything said on social media
How the platform earns
The platform wallet is the fee claimer of the presets: it receives the platform share of trading fees on every coin, including the anti-sniper fee collected in the first minute, plus the block 0 premium. Meteora takes its own protocol fee. On Fair the creator earns nothing from trading fees. On Builder the creator earns 50%. There is no launch fee beyond network costs.
What you are trusting
- Meteora's Dynamic Bonding Curve program holds the coin's funds and runs the curve. We don't write, hold or upgrade it.
- The preset config is on-chain and readable. The Fair score reads it back so you don't have to take our word for the terms.
- The Minnowpad wallet that claims fees is a normal wallet. It holds platform revenue, not users' funds.
- The interface is ours. A bug there could build a wrong transaction: your wallet shows what you sign.
What isn't proven yet
- A launch on mainnet. The presets are tested on a local validator against the real program, not live.
- Metadata storage. Images and metadata need a Pinata account configured on the server.
- How the fee and anti-sniper numbers behave under real trading volume.
- An independent review of our interface code. The curve itself is Meteora's.
