Key Functions

Portal.swapExactInput

Used for buying and selling tokens on the bonding curve.

Buy (BNB → Token):

• inputToken: 0x0000...0000 (native BNB)

• outputToken: token address

• inputAmount: BNB amount in wei

• msg.value: must match inputAmount

Sell (Token → BNB):

• inputToken: token address

• outputToken: 0x0000...0000 (native BNB)

• inputAmount: token amount

• Requires token approval or EIP-2612 permit data

Portal.newTokenV5

Deploys a new token (standard or tax, without vault).

VaultPortal.newTaxTokenWithVault

Deploys a tax token with a vault configuration (Split or Gift vault).

Vanity Addresses

Tokens deployed through Flap use CREATE2 for deterministic addresses:

Token Type	Address Suffix
Standard	...8888
Tax	...7777

The salt is computed by iterating random values until the predicted CREATE2 address ends with the required suffix.
