举例的交易链接

这是一个FST的ERC20转账记录，如果试图估计gas

// 实例化fst合约
.....

fst.transfer.estimateGas("0x0c6fcaaae530d029699261179503b56ca3bdd77d", chain3.toBigNumber("0x0000000000000000000000000000000000000000000000b197a2030213b00000"))

fst.approve.estimateGas("0x0c6fcaaae530d029699261179503b56ca3bdd77d", chain3.toBigNumber("0x0000000000000000000000000000000000000000000000b197a2030213b00000"))

返回结果是3570，而实际的transfer交易是34797

在DAPP开发中，要么自己尝试后，找出一个固定的安全边界，想按照传统方式先做燃料估计再调用就会有问题，尤其是涉及到合约升级后，gas的变动也要改程序就很令人困扰
