I've been deep in
@centrifuge's new vault stack for a while now, and I'm more of a fan every day. It's the closest thing to a complete vault I've read. It has very modular architecture, I think every RWA protocol would want to build on it.
It runs one pool balance sheet with N share classes as claims on it, async requests with pluggable settlement policies, and a NAV with a double-entry ledger.
It'll be a real game changer in the space once it is launched.
