How to create a pool on OP Mainnet (Uniswap v2, v3 & v4)
Create a new pool on OP Mainnet with Uniswap v2, v3 & v4 — directly on the official contracts/programs, with a market-checked starting price and the first liquidity in one flow.
When should you create a pool?
Create a pool when your token pair has none yet, or you want a different fee tier (e.g. 1% for volatile tokens, 0.05% for stablecoins). The creator sets the starting price; if it differs from the market, arbitrage bots immediately take the difference out of your liquidity.
Step by step
- Open Create pool and choose OP Mainnet and the DEX (Uniswap v2, v3 & v4).
- Enter both tokens (contract / mint address). BaniPool checks token security and whether the same pool already exists.
- Pick a fee tier and set the starting price — BaniPool compares it with the market price and warns you if it deviates.
- Fill in the first deposit (both tokens, or Zap with one token) and its price range.
- Sign in your wallet (MetaMask, Rabby, Coinbase Wallet). The pool is created and seeded, then appears on its pool page and in your Profile.

Snipers & the starting price
New pools are sniper targets: once a pool is visible, bots can buy first or move the price before your liquidity lands. Seeding liquidity together with creation, using a market price and — on Solana — the Jito private mempool reduce this risk.

FAQ
How much does it cost to create a pool on OP Mainnet?
Only the network fee plus your first deposit.
What happens if the starting price is wrong?
Arbitrage bots will trade the pool until it matches the market, taking the difference from your liquidity. That is why BaniPool shows the market price and rejects the deposit if the pool price moved away from the price you set.
Can I create a pool for a token I just launched?
Yes. Enter your token address; BaniPool reads the contract on-chain. Make sure the token's authorities and taxes are in order, because its security score is shown to every pool visitor.
