These days, I've been reviewing cross-chain bridge accident retrospectives. To put it simply, many pitfalls are still the classic issues: too many signers with too little permission control, oracle data drifting and causing fluctuations, and everyone’s least favorite—"waiting for confirmation." I now prefer to be a bit slower with cross-chain transactions; after clicking, I’ll just queue up for a moment, take a sip of water, and then refresh/retry, rather than rushing for speed. Recently, AI agent automated trading has been quite popular, but I always feel that many people are just hyping up "automation," while few actually take the time to carefully define permissions, rollbacks, and exception paths. Anyway, with bridges, one wrong move can really cause everything to collapse.
