Why CEXs are incentivized to do this:
- Can “list” every token and capture those trading fees.
- Can drive users to their own chains.
- Can disrupt themselves by going onchain before new entrants do.
- Owning the signing experience as a web wallet will be incredibly sticky (more so than the balance, history, and discovery experiences).

This time next year, I bet you’ll be able to DEX trade in a major CEX retail app (same trade UI as their CEX UI).

But it’s crucial that this experience uses a passkey-based web wallet (something usable onchain generally), otherwise it will only be expansive to the CEX’s bottom line, not to crypto overall.

Session keys here will mean you don't have to leave the app to sign or have an in-app browser pull up appear to sign with a passkey.

Will feel like your normal trading experience.
