Regarding the last one, please check the template map for identification. I have changed the address several times; some failed to process with the x bot, so I switched to a new BSC USDC address. The prerequisite for this task is that you have 1 USDC plus a little BNB for fees in your payment account. The second to last task requires you to propose 1 USDC at the very bottom, which also requires BNB and USDC.
