EDX Markets announced on 5 November that it was introducing a CBTC/USD spot market for eligible institutional clients, linking its trading venue to BitSafe’s Bitcoin-backed asset on the Canton Network. The parties describe CBTC as backed one-for-one by Bitcoin and designed for use in Canton’s privacy-oriented financial ecosystem. Granite River Trading will provide two-sided liquidity in the new spot market. The important new feature is a specific centralised execution point for an instrument previously marketed principally through a token-network context, not proof that Bitcoin itself has moved onto an exchange or that all potential arbitrage problems are solved.[1]
BitSafe says the asset uses distributed reserve controls and Chainlink Proof of Reserve to increase transparency of backing. That description is an issuer representation about controls and monitoring; it is not the same as an independent audit establishing unrestricted, immediate redemption for every holder. A broker or liquidity provider must understand where underlying BTC is held, the rules governing issuance and redemption, which institutions can interact with the asset, and whether market-making inventory can be transferred or redeemed when spreads widen.[1]
Verified record, scope and limitations

| Promotions | Conditional fee and reward incentives, not zero total execution cost |
The difference between an announced pair and a liquid market
EDX’s announced initial trading pair is CBTC against US dollars. It has plans for CBTC perpetual contracts in the coming weeks and a CBTC/BTC spot pair later. Canton Coin is also contemplated as eligible collateral for prospective CBTC perpetuals. These are distinct future steps, not products or collateral rights that the 5 November announcement proves are already operational. Treating 'coming weeks' as a firm launch date would misstate execution and risk-management readiness.[1]
The release also mentions incentives including zero trading fees for eligible CBTC trades, coverage of certain withdrawal fees and Canton Coin rewards tied to eligible volume. Each promotion depends on programme terms and eligibility. Zero venue commission would not automatically mean zero spread, custody, financing, blockchain or redemption cost. In an institutional setting, the effective cost of exposure depends on order-book depth, slippage, inventory availability and the ability to move assets between venues.[1]
Granite River’s participation addresses an essential first-day question: who will quote the new market on both sides? A named liquidity partner is useful, but it does not constitute a public guarantee of fixed minimum depth or continuous narrow spreads. The editorial test for future progress is measurable live market quality and verified settlement or redemption performance, not a count of proposed market pairs. EDX’s step is relevant because it combines a cash-facing order book, a named market maker and a Bitcoin-backed Canton asset, while leaving derivatives approval, collateral treatment and economics explicitly conditional.[1]
