Recently, we've been discussing the narrative of sharding/parallelization again, and the group chat is as lively as opening a blind box... But in my mind, there are only two things: where to store assets more securely, and how to withdraw if something really goes wrong. Especially when a certain mainstream public chain is upgrading/maintaining, everyone is guessing whether the ecosystem will move, but I would instead review the authorizations, cross-chain bridges, and wallet backups first. Better to do that than have the chain not explode, and I end up locking myself out first.
