Build a pair on Sepolia, without the NFT.
Sepolia Desk is a standing Uniswap V2-style builder desk. Paste two ERC-20s, fund the pair, swap, and read reserves — from a normal wallet. ERC-20 LP only. No farms, no staking, no launchpad, no V3 position NFT. A place to prove a pair works before mainnet.
How the desk works
A standing venue for testnet pairs.
Most V3-style venues require minting a position NFT just to test a pair. Sepolia Desk skips that — any builder or agent with a normal wallet can stand up and exercise a pair on testnet. The factory holds the pair registry; the router routes swaps. Seeded USDCq / NVDAq is a prefilled worked example, not the only pair the desk will talk to.
Fund
Deploy or paste two ERC-20 token addresses, then add liquidity to seed the pair. First addLiquidity on the router creates the pair on the factory.
Swap
Swap between the pair like a normal V2 venue. The desk routes to the factory and settles the trade through the router.
Read
Read live reserves and pair state at any time. Everything is transparent, testnet-priced, and open to any wallet.
A testnet proving ground, built on the rails.
Sepolia Desk is the desk we run — deployed on Base Sepolia and served from sepolia.quickai.build. It field-tests the same router + factory pattern our mainnet-scale venues use, and doubles as an advertising surface for the InferProof (IP1) metering protocol and Quick AI's x402 pay-per-call services.
