What it bears on
R3Do we know what this instrument is, legally, in every venue we operate?
needs design
ETH is a digital commodity in the United States and stablecoin law is in force. Market-structure legislation stalled, and jurisdictions are diverging.
R6Who is the counterparty when there is no counterparty?
needs design
