SmartSwap - Dev Guide

---

1. Pepe Terminal B2B Swap (For Developer)

Token Registration:

• Developers connect their wallet to the Pepe Terminal platform (via Web3/MetaMask).

• The developer submits the contract address of the token they wish to list.

• The smart contract checks whether the wallet address (msg.sender) matches the token owner (via the owner() function or similar logic).

• If it matches, the token is allowed to be listed, and the creator’s address is stored for fee distribution.

• If it does not match, the transaction is rejected (revert).

Automatic Fees:

• Each swap involving a listed token will incur a fee (e.g., 0.1% platform + 0.1% creator).

• The creator’s fee is automatically sent to the stored creator address during listing.

Interaction with PancakeSwap:

• Swaps still use PancakeSwap's pool and router.

• Additional fees are taken before/after the swap via the PancakeSwap Router.

2. Smart Contract

Smart Contract Includes:

• A function for listing tokens with creator verification.

• A mapping to store listed tokens and their associated creator addresses.

• Swap logic that distributes fees to both the platform and the token creator.

3. Smart Contract Explanation

Listing Token (listToken):

• Checks whether the token is already listed (isTokenListed).

• Calls the owner() function on the token contract to get the owner’s address.

• Verifies whether msg.sender (the connected wallet address) matches the token owner.

• If verification passes, it stores the creator address and marks the token as listed.

Swapping Tokens (swapTokens):

• Only allows swaps if at least one of the tokens (input/output) is listed.

• Takes a total fee (0.2% split as 0.1% to platform + 0.1% to creator).

• Distributes the fee accordingly to the platform and creator (if any).

• The remaining amount is used for the swap via PancakeSwap Router.

Events:

• TokenListed: Logs when a token is successfully listed.

• SwapExecuted: Logs every swap for transparency.

6. Additional Notes

Tokens Without owner():

• If a token lacks the owner() function (e.g., older or custom tokens), developers can be asked to upload off-chain proof of ownership or the creator fee can be skipped.

Flexible Fees:

• A function to adjust platformFee and creatorFee (only the platform owner can modify these values).
