Episode notes
Stablecoin Yield Ban Helps Issuers More Than It Hurts
- The CLARITY Act compromise effectively bans stablecoin-native yield, shifting economics toward distributors and product creativity.
- Nic Carter and Matt Walsh argue this likely helps issuers like Circle by preserving economics while pushing yield delivery into broker-dealer or tokenized money-market structures.
Tether Hires Big Four For First Audit
- Tether retained a Big Four firm to perform its first independent financial audit, a notable institutional step for USDT.
- Nic notes it's unclear which firm and doubts it will be 'Genius compliant' given Tether's Bitcoin backing detail.

- Nic suggests Coinbase may regret rejecting a bill while the current administration and Congress are aligned to pass industry-facing legislation.
