I really felt stupid just now... When copying the address, I accidentally added an extra space, and as a result, the transfer page kept showing errors. I thought it was another network gas spike, and almost nervously went to the mainnet to "save some trouble." After calming down, I remembered: first do a quick check on L2, confirm that the process and address are correct, then go back to the mainnet for the final step; you'll be much more relaxed. Basically, my current compromise is: for daily interactions and trying new protocols, use L2 as much as possible, saving gas and being faster; only do large or critical operations on the mainnet, which is more expensive but more reliable. By the way, recently, the tags on on-chain data tools have been criticized for being outdated and even misleading. In such cases, don’t trust the "marked as safe/XX organization" labels too much; double-check the address and contract yourself. Anyway, I’ve already been educated on this... that’s all for now.
