KQMG Token

KQMG._splitOtherToken() (#1253-1303) ignores return value by doge.transfer(_receive,receiveAmount) (#1259)
KQMG._splitOtherToken() (#1253-1303) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1285)
KQMG._splitOtherToken() (#1253-1303) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1296)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.
