Zui Lu makes money!!! Recently received rewards of several U, with the maximum transaction fee being only a fraction of U, in exchange for several U and dozens of U in return, which is much more reliable than doing contracts. If anyone doesn't know how to complete the tasks, feel free to ask questions in the comments below, and I will answer all of them! This time, the task post must be marked with @OpenLedger and include topic tags #OpenLedger and $OPEN to receive rewards.
