openfair vs pump.fun: fair launch platforms compared (2026)
The short answer: pump.fun charges a ~1% platform fee on every trade forever and keeps launch logic in shared contracts; openfair deploys every token as its own immutable, auto-verified contract, takes no mandatory trading fee (the creator sets 0–10% and keeps the majority share), and locks Uniswap V3 liquidity in a harvester contract that has no withdrawal function. Both are one-transaction, no-code launchpads – the difference is who owns the token economics.

Where the models differ most
- Fee ownership. On openfair the trading fee belongs to the creator: set 0% for a community token or up to 10% and keep the majority (the platform share is the creator's choice, minimum enforced only for launches prepared via the API). On pump.fun the platform fee is fixed and permanent.
- Verifiability. Every openfair token is a standalone contract whose source is verified on the block explorer within minutes – the "verify, don't trust" model. Rug-relevant properties (locked LP, no dev-buy, team vesting) are readable on-chain and summarized in a trust score.
- Anti-snipe. openfair's bonding curve can rate-limit the global sale and cap per-wallet buys during the first minutes – snipers cannot scoop the curve bottom.
Which one should you pick?
If your community lives on Solana, pump.fun is the incumbent with the deepest meme liquidity. If you want an EVM launch where you own the fee switch, the contract is provably immutable, and liquidity is locked by construction rather than by promise – launch on openfair.
