I've recently been paying attention to cross-chain stuff again, especially IBC and this kind of "message passing." To put it simply, you think you're just transferring assets across chains, but in reality, you're dealing with a combination of two consensus systems plus a bunch of relays/light clients/proofs: source chain avoiding malicious behavior, target chain not acting up, relayers not slacking off, client verification code without vulnerabilities, channel configurations not slipping up... any weak link in the chain can cause you trouble. Bridges are even more intense; often, you're trusting a multi-signature/multisig custody/oracle "person," while pretending it's just a technical solution.

I'm not really talking about "conquering fear" anymore, but practicing: before I try cross-chain arbitrage, I ask myself who I really trust today, and whether I can escape if things go wrong. After practicing for a while, my hands don't itch so much... probably.

By the way, there's a lot of noise about NFT royalties: on one side, wanting creator income; on the other, wanting secondary liquidity. Ultimately, it's about whether you trust the other party to follow the rules. In the on-chain world, trust costs are always hidden in the line you’re too lazy to read. Anyway, I’ll start with small amounts to test, so I don’t get wiped out again by liquidation cascades.
