Before graduation

  1. Enter an ETH budget.
  2. The web app resolves the token’s curve from the factory and reads current onchain state.
  3. It calls quoteBuy and calculates a slippage-protected minimum token output.
  4. Immediately before requesting a signature, it simulates the exact buy(minTokensOut, deadline) call.
  5. Your wallet sends ETH to the curve on Base Mainnet.
  6. The app waits for the receipt and refreshes contract and indexed views.
The default curve slippage is 1%. The interface permits a custom value from 0.01% through 20%. A quote has a deadline and is invalidated when the amount, wallet, network, side, or relevant state changes. If a buy would cross the terminal reserve, the contract accepts only the exact gross input required, sends the remaining curve inventory, triggers graduation, and refunds excess submitted ETH.

After graduation

The token page switches to a validated Uniswap V3 swap flow. The UI checks the canonical pool, factory, WETH, QuoterV2, and SwapRouter02 relationships; obtains an exact-input quote; simulates the transaction; and submits it through the browser wallet.
Expected output is not guaranteed. The transaction reverts if output falls below the reviewed minimum, but gas can still be spent on a reverted transaction.
