# Buy tokens

> Buy on the curve with native USDC or in the graduated V3 pool with ERC-20 USDC.

## Active curve

1. Enter a gross native-USDC budget.
2. The app resolves the dedicated curve from `CooketFactoryV3` and calls `quoteBuy`.
3. Review accepted gross, fee, net curve input, token output, slippage minimum, and deadline.
4. The app simulates the exact contract request, verifies wallet/network context, and estimates value plus gas before asking the wallet to submit.
5. The app waits for a receipt. If confirmation becomes unresolved, it preserves recovery information instead of assuming failure.

The default slippage setting is 1%; the interface accepts 0.01% through 20%. A terminal buy may accept less than the submitted budget and refund the excess atomically.

## Graduated market

Graduated buys exchange 6-decimal canonical ERC-20 USDC for the launch token through the verified SwapRouter. They require an ERC-20 allowance, a QuoterV2 result, a minimum output, and a five-minute deadline. The swap sends no native value.

<Warning>These are Arc Testnet assets. A quote is not a guarantee, and a reverted transaction can still consume testnet gas.</Warning>
