Last night I made a cross-chain transfer of funds. I picked a new bridge—the fees were half as much, and I was pretty happy about it. In the end, though, the funds didn’t arrive for forty minutes. I spent a long time checking on-chain before I finally realized that the validator set in the middle had gone offline, and the money was just hanging in midair.

Now that I think about it, it’s kind of scary. Native channels like IBC are at least okay—you can trace things back. Some third-party bridges, to put it bluntly, basically hand custody of private keys to a few multi-signature nodes. If those nodes have issues, your coins are just numbers. Lately I keep seeing big on-chain transfers interpreted as “smart money moves,” but a lot of the time it’s actually the bridge rebalancing. People like me just follow along and rush in, not even knowing which step is where the funds are getting stuck.

Anyway, for cross-chain transfers now, I start with small amounts. I’d rather pay extra gas to check the liquidity pool depth and the validator history. In the good times, everyone praises how fast and cheap the bridges are; only when the wind turns do you find out who’s been swimming around naked.
