/**
 * 用于钱包显示资产变动
 *
 * 资产变动: 1. 仅有手续费 2.从钱包地址向合约转账的金额、手续费
 * 此方法`getInfo`用于钱包账户，而合约地址不属于钱包账户，所以这里的入参不会是合约地址
 * 若toList只有一个Coin，要么是调用者自身扣了手续费后的找零，要么是from全部转移到另一个地址
 * 若toList有两个Coin，则必然有一个是从钱包地址向合约转账的金额 - 对应的是合约地址，另一个是调用者自身扣了手续费后的找零 - 对应的是调用者的地址
 *      这里的地址有三种情况，一是合约调用者的地址，二是合约转账(从合约转出)的`to`地址，三是合约Token转账的`from`,`to`
 *      综上，由于方法入参不会是合约地址，因此除合约调用者地址外，其他地址传入都返回 `0`
 * @param address
