The U.S. Senate's discussions on the cryptocurrency market structure bill have hit several contentious points, including official ethics, stablecoin yield relationships, SEC powers, and DeFi treatment. As a result, a breakthrough is unlikely before the holiday recess, pushing the bill's progress into January. Ethereum developers have proposed the ERC-8092 standard to link blockchain accounts across chains. This proposal allows two blockchain addresses to formally declare a relationship, verify it with a cryptographic signature, and dissolve it at any time. The standard supports various signature types, including EIP-712, enabling functionality beyond Ethereum. The Office of the Comptroller of the Currency (OCC) has issued Interpretive Letter 1188, allowing U.S. national banks to conduct "riskless principal" crypto transactions. This involves buying from one client and immediately selling to another without holding token inventories. The OCC also indicated that digital asset custody could fit within standard banking frameworks, and national trust charters remain a possibility for some crypto firms.
