XrpTiger._splitOtherToken() (#1253-1299) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1281)
XrpTiger._splitOtherToken() (#1253-1299) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1292)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
