ChainThink report, April 3: According to community user feedback, the token Gift launched on the BNB Chain via the Four platform failed to sell, suspected of being a 'Pi Xiu' scam. The token has now surpassed a market cap of $1 million, yet users are unable to exit and realize profits.

The root cause is that the contract cannot be modified after deployment to change the founder address, and the founder contract address lacks both receive() and fallback() functions, rendering it incapable of receiving BNB. When users attempt to sell tokens, the transaction fails during an internal call to _swapForETH(founder, amountFounder) in _dispatchFee(), throwing an error: "founder is a contract address without receive()/fallback() functions and cannot receive BNB — sale failed." Further response from the Four platform remains pending.
