Test swaps on Base Sepolia.

Explore WETH / USDC test-token quotes on Base Sepolia. Test swaps are enabled with Base Sepolia test tokens, which have no monetary value. An earlier MetaMask alert classified the approval spender 0x94cC0AaC535CCDB3C01d6787D6413C739ae12bc4 as “Malicious” / “Address flagged as high risk.” Uniswap lists this as Base Sepolia SwapRouter02, but that identity match does not clear the alert. If your wallet shows a malicious or high-risk alert, do not connect or sign; close the page.

Application fee: none. Pool and network fees are separate. Price impact compares the quote with the selected pool’s current spot price, excluding the pool fee; it can change before execution. Native ETH is used for network fees; this pair swaps wrapped ETH.
