Everyone is shouting about IBC, messaging, and various bridges mixed together, but honestly, a cross-chain transfer is just about who you trust: the source chain / target chain itself should not crash or rollback; the relay / relayer in the middle should not be lazy or malicious; the light client / verification logic should not be poorly written; plus those "patches" like multi-signatures, oracles, and permission switches. The more components there are, the more uncertain you feel... Anyway, every time I cross, I have to watch the on-chain records for a long time, afraid of getting stuck in a queue and pretending to be dead.

New L1 / L2 projects trying to boost TVL with incentives are the same—it's lively, but it's not without reason that veteran users criticize "mining, selling": liquidity moves faster than the narrative, and once the bridge opens, it's like opening the floodgates, with everything else relying on trust to hold up.
