US Senators are approaching a critical vote on crypto market structure legislation, scheduled for January 15, as divisions persist over protections for DeFi developers. The legislation aims to resolve jurisdictional disputes between the SEC and CFTC, with the SEC overseeing ancillary assets and the CFTC taking charge once distribution is decentralized. However, unresolved issues include ethics provisions and protections for software developers, highlighted by recent prosecutions of crypto developers under money transmission laws. The Blockchain Regulatory Certainty Act, which seeks to clarify that crypto developers are not money transmitters, remains a point of contention. Meanwhile, internal Republican disagreements have surfaced over stablecoin yields, with some senators aligning with the banking sector's concerns about potential impacts on bank deposits. The American Bankers Association has warned that stablecoin rewards could divert significant funds from traditional banks, affecting their lending capabilities.
