Advanced checks

Not checked. This checks the trading wallet without approvals or signatures. Receiving USDC fees does not require token spending permission or an ETH balance.

This exact ERC20 approval does not expire automatically. If you stop before the swap, it may remain until spent, changed, or revoked in your wallet. It does not perform a swap. A fresh quote and review are required before trading.

Read-only estimate. No approval is requested.

Successful swaps collect the disclosed 0.25% application fee. Buys deduct 0.25% from the USDC input. Sells deduct 0.25% from the USDC output. Fees round down to the nearest 0.000001 USDC. Pool and network fees are separate. Each approval and swap requires your wallet confirmation. Independent reviews and real-wallet transaction validation are incomplete.

Choose Buy WETH or Sell WETH, enter an amount, and review the application fee, pool fee and minimum received.
Review each permission in your wallet. An approval is a separate step; refresh the quote before the swap.
After submission, track the transaction in Your recent swaps or on BaseScan. Wait for its result before retrying.
