Welcome to the Monday edition of the 51 Insights digital asset newsletter.

Sibos opened in Miami on Monday, and the day's big deals had one thing in common. I think crypto went into the back office, while the front door stayed where it was.

Here's what matters in digital assets this week:

• Citi plans stablecoin checkout for its merchants, run by Coinbase

• Goldman offers its Treasury fund to crypto trading firms through Lynq

• Hester Peirce leaves the SEC on Friday

Crypto moves to the back office

What's going on here?

Citi and Coinbase widened their partnership. Spring by Citi, the bank's checkout service, will let merchants accept stablecoins, with Coinbase running the rails. Citi's banking will also sit behind Coinbase's new virtual accounts. The rollout starts in the US. Separately, Citi Token Services went live in Japan and the UAE, bringing it to seven markets.
