Solana Fair Launch Explained: How Bonding Curves Work
Updated 2026-09-06 · 7 min read
A fair launch replaces a private presale with public on-chain price discovery. The token is tradable against a bonding curve from the start under the same public rules, but buyers do not all pay the same price: earlier and later trades execute at different points on the curve.
The mechanics are simple once you see the shape of them, and they explain most of the behaviour you notice on launch platforms.
What a bonding curve actually is
A bonding curve is a formula that sets the token price as a function of how much of the supply has been sold. Early buys are cheap, later buys are more expensive, and the price moves along the curve deterministically with each trade.
There is no counterparty and no order book. You are trading with the curve itself: SOL goes in, tokens come out, and the price for the next buyer moves up.
Graduation
Once enough SOL has accumulated on the curve, the launch graduates: the collected liquidity is migrated into a real AMM pool and normal two-sided trading takes over. From that point the token behaves like any other pair on a decentralised exchange.
LaunchMemes currently offers two fair-launch routes. Raydium LaunchLab graduates to Raydium CPMM, while Meteora DBC graduates to Meteora DAMM v2. You choose the route before launch, and the graduation path is part of that launch design rather than a manual pool-creation step afterward.
Fair launch vs standard token plus pool
A bonding-curve launch removes the need to seed a manual pool and makes the launch rules public on-chain. It does not stop the creator, bots or other wallets from buying early through the same public curve, so holder concentration still matters.
- Fair launch: tradable immediately, price discovery starts at the bottom of the curve, no initial price to pick, liquidity is accumulated by buyers rather than seeded by you.
- Standard token plus pool: you choose the starting price by the ratio you deposit, you supply the initial liquidity yourself, and the token is not tradable until you open the pool.
What fair launch does not protect against
A fair launch prevents a private presale. It does not prevent someone from buying a large share of the curve in the first seconds with their own SOL, from multiple wallets, or from selling into later buyers.
Read holder concentration before you buy anything launched this way, exactly as you would with any other token. The launch mechanism describes how the market opened, not who currently holds it.
Fees on a fair launch
LaunchMemes standard Fair Launch currently has a 0 SOL platform creation fee. That does not mean zero blockchain cost: Solana network/account costs still apply, and buys and sells on the bonding curve pay trading fees according to the selected Raydium or Meteora route.
The exact trading-fee split and transaction costs in force are shown in the launch interface before you sign. The interface is the final source for transaction-specific amounts.
Frequently asked questions
Is a fair launch safer than a normal token launch?
It removes presale allocations and it starts price discovery publicly, which are real improvements. It does not make the token a good investment or prevent early buyers from selling into you.
What happens when a fair launch graduates?
The bonding-curve launch moves into its configured AMM route. Raydium LaunchLab graduates to Raydium CPMM; Meteora DBC graduates to Meteora DAMM v2.
Can a fair launch fail to graduate?
Yes. If not enough SOL is ever bought on the curve, the launch simply never reaches the graduation threshold.
Do I need to supply liquidity for a fair launch?
No. The liquidity comes from the buyers on the curve, which is the main practical difference from seeding a pool yourself.
