EDX Markets said in a November 5 announcement that it had partnered with BitSafe to introduce spot trading in CBTC, a Bitcoin-backed token built for the Canton Network. The companies described it as CBTC’s first centralized-exchange listing, with trading against US dollars for eligible institutional clients; the announcement does not establish trading volume or access for every Canton participant.
EDX and BitSafe say each CBTC is backed one-for-one by Bitcoin, but CBTC is a separate token, not native Bitcoin. The cited proof-of-reserve feed is not necessarily a complete audit of liabilities, ownership or redemption processes, and one-for-one backing does not guarantee that CBTC will always trade at parity.
