The CLARITY Act's Section 404 officially bans passive yield on stablecoins — the kind that pays interest like a savings account — but it allows rewards tied to what customers actually do, like trading or transacting. That carve-out is now driving real product moves. This week, Coinbase announced a partnership with Ethena, a synthetic dollar protocol, to let stablecoin holders earn returns through delta-neutral basis trades. The idea: short perpetual futures while holding spot assets, generating yield that counts as activity-based, not passive.
What Section 404 Actually Does
The law, still in draft, draws a hard line. You can’t just park stablecoins and collect interest. But you can earn rewards for taking action — executing trades, providing liquidity, or using the platform. Traditional US banks lobbied hard for this language, arguing that unregulated yield products on crypto exchanges could pull deposits away from the banking system and create systemic risk without FDIC-style protections. The result is a regulatory environment that forces innovation on the yield side.
Coinbase and Ethena's Workaround
Coinbase turned to Ethena, which operates a synthetic dollar protocol that generates returns through active trading strategies — not passive holding. That model fits neatly under Section 404's permission structure. Coinbase serves as Ethena's primary custodian, wallet provider, and perpetuals trading venue. Coinbase Ventures has invested, and together they support over $5 billion in assets. For users, it means yield that looks and feels like interest but is technically earned through ongoing market activity.
Dimon Pushes Back
JPMorgan CEO Jamie Dimon isn't buying it. He criticized the CLARITY Act draft, saying it lets crypto platforms pay what amount to interest-like returns without the regulatory safeguards banks are held to. In his view, the current form would create an uneven playing field, and he warned that banks would not accept it. That sets up a political fight as the bill moves toward final language.
The Stakes for Coinbase
Coinbase reported $305.4 million in stablecoin revenue last quarter — 52% of its subscription and services revenue. The exchange holds an average of $19 billion in USDC, representing more than a quarter of all USDC in circulation. Losing the ability to offer any kind of yield on that base would hit the bottom line hard. The Ethena deal is a hedge against that risk, but it also tests how far activity-based rewards can stretch before regulators call them what they really are.
The CLARITY Act is still in draft. Dimon's objection signals that the banking lobby isn't done shaping it. For now, Coinbase is betting that a protocol designed around active trading can thread the needle — and that the revenue is too big to leave on the table.
