On-chain repo transactions just got real. Solstice executed the first institutional repo settlement through a membrane-based protocol with Cor Prime, using USX as collateral. Here's what makes it different: during the repo term, that collateral isn't just sitting there—it keeps generating 10-15% delta-neutral yields. Traditional finance? Your collateral earns nothing while locked up in a repo. The $4.6 trillion daily repo market is starting to wake up to what blockchain can do: capital that actually works instead of capital that waits.
