These days, someone is again watching large on-chain transfers and the movement of hot and cold wallets on exchanges, shouting "Smart money is coming." I find it quite amusing but also exhausting... my neck is stiff. To put it simply, when it comes to cross-chain bridges, the most easily overlooked issue isn't the transaction fee, but the "waiting for confirmation" process: who is signing in multi-signature transactions, and whether the signature threshold has changed; once the oracle feed price/status gets stuck, the assets on both sides of the bridge become like they are floating in the air. Don't rush to jump in; just because the confirmation count hasn't completed, you might think the funds have arrived, but in reality, it's just your UI giving you a false sense of reassurance. Anyway, whenever I see the "fast in and out" related to bridges, my first reaction is to wait and treat the risk as slippage.
