Liquid isn't custodial. It self custody on a federated chain. That's way different.
Self custody of Bitcoin IOUs. At the end I can still get rugged.
If you know the trust model of liquid, you know the chances of a liquid rug are near zero. But yes. This is why I advocate for layers of trust. Pocket change -> custodial lightning, a few million sats of liquidity -> liquid, cold storage -> on chain. This is the cheapest way to use Bitcoin in any way you need at any time you need it.
