我正在尝试使用 ERC223 标准创建一个新令牌。代币已创建，但当我尝试将代币转移到其他钱包时，会创建交易哈希并且交易失败。代币从我的钱包中扣除，而不是添加到目标钱包中。
这是我的代币智能合约代码：
pragma solidity ^0.4.9;
contract ContractReceiver {
struct TKN {
address sender;
uint value;
bytes data;
bytes4 sig;
}
function tokenFallback(address _from, uint _value, bytes _data) public pure {
TKN memory tkn;
tkn.sender = _from;
tkn.value = _value;
tkn.data = _data;
uint32 u = uint32(_data[3]) + (uint32(_data[2]) << 8) + (uint32(_data[1]) << 16) + (uint32(_data[0]) << 24);
tkn.sig = bytes4(u);
}
}
