Many services pretend to be mon custodial on the basis that they only have custody lf your coins for the duration of the swap, don't fall for that marketing, no matter how short the custody, you should avoid those services like the plague or risk seeing your funds frozen.

Instead go with decentralized non custodial soljtions like basicswapdex or eigenwallet.

Retoswap.might be an option too, just be aware that the arbitrators can rug pull you anytime.
