Midnight on-chain browsing and I saw someone cross-chain and wait half a day, then complain "the network is not working"… Honestly, trusting a cross-chain transaction isn't just about the front end of that bridge, you also have to trust: the final confirmation of the source chain (don't roll back and shout about the arrival at the same time), the message passing/relay system in the middle (who's forwarding, is there room for malicious activity), the verification logic of the target chain (light clients/multisig/validators, different names but all "who do you trust"), plus whether the deployed smart contract has vulnerabilities.

Adding my own PTSD: when the slippage for a swap is set too high, there are a bunch of eyes watching in the mempool, and it’s easy to get front-run.
Recently, hardware wallets are out of stock, phishing links are everywhere… don’t rush to click "official airdrops/cross-chain compensation," first check the authorization and redirect addresses. I’d rather be slow than risk losing funds in the middle of the night.
