Hyperliquid has struck a deal with Coinbase that will let it keep roughly 90% of the reserve income on the roughly $6 billion in USDC sitting on its platform — about 8% of the total USDC float. The arrangement, which Coinbase will treat as on-platform USDC, effectively redirects the bulk of stablecoin seigniorage away from the issuer and toward the venue that aggregates users and trades. JPMorgan analysts called it a negative shift for Circle and Coinbase's historical USDC economics.
Coinbase cuts Hyperliquid in on reserve income
Under the new terms, Coinbase collects reserve income on the USDC held on Hyperliquid and then pays roughly 90% of that income back to Hyperliquid. Historically, interest on reserves funded the issuer's business model. Now a venue captures the bulk of it. JPMorgan analysts framed this as a negative shift for Circle and Coinbase's historical USDC economics, as less interest stays with the issuer side. The deal underscores how exchanges with large stablecoin pools can negotiate a slice of the yield that used to flow entirely to issuers.
SEC engagement on derivatives
The SEC's Crypto Task Force held a formal meeting with Hyperliquid-linked representatives on July 14, 2026, to discuss on-chain derivatives and market structure. The meeting suggests regulators are paying close attention to how venues like Hyperliquid handle leveraged trading and settlement. No public statement followed the meeting, but the fact that it happened at all signals the agency is moving beyond enforcement-only mode into active dialogue with on-chain platforms.
USDH officially retired
Hyperliquid completed the operational sunset of its native unit USDH on June 20, 2026, and normalized to USDC rails. For stragglers, Across Protocol provided a fee-free, one-to-one path to convert USDH to USDC on HyperEVM. The migration removes a layer of complexity for users and aligns Hyperliquid fully with the dominant stablecoin. With the Coinbase deal now in place and the SEC meeting on the books, the next question is whether other exchanges will try to negotiate similar reserve-sharing arrangements — and whether regulators will let them.
