Circle vs Tether: What the Heka Funds Dispute Reveals

If you move size in stablecoins, you probably care less about the drama and more about the rails. Can I redeem on time? Who can shut the door on me, and under what rules? The Circle vs Tether backdrop to the Heka Funds dispute puts those questions front and center.

This isn’t abstract. Newly public filings show how one fund sat between two rival issuers, how limits got yanked during stress, and how a legal fight ended. For treasuries, market makers, and crypto funds, the lesson is simple: operational sovereignty beats brand loyalties.
