Bitget has introduced an Open Custody Network (OCN) that connects external institutional custodians and banking partners to the exchange’s trading systems, aiming to let eligible users trade without placing all their underlying crypto assets directly in the exchange’s custody.
In its November 5 announcement, the cryptocurrency exchange said the service links custody arrangements with spot, margin and futures markets through asset mirroring. Access, supported markets and settlement terms depend on the selected custody solution and an institution’s eligibility.
Trading Access Without Moving Every Asset Onto the Exchange
The conventional exchange model often requires customers to deposit assets into wallets controlled by the venue before trading. That creates concentrated operational exposure if the exchange suffers a security, liquidity or governance failure.
The approach described by Bitget is different: a participating custodian holds eligible assets while a corresponding trading balance is made available on the exchange. Transactions can then be settled according to the relevant custody and settlement arrangement.
Asset mirroring should not be interpreted as the creation of risk-free collateral. The arrangement still depends on valuation, authorized settlement instructions, counterparty obligations and the infrastructure connecting the custodian with the venue.
Network Builds on Existing Custody Partnerships
Bitget’s earlier institutional support documentation identifies a range of custody options, including Copper ClearLoop, Fireblocks Off Exchange, Cactus Custody Oasis, OSL MirrorEX, Bitfire PrimeMirror and Sygnum Protect.
Those providers use different structures. Some enable custody accounts to support trading credit while others incorporate settlement cycles, collateral pledges or lending features. A customer should not assume every option offers identical protections.
Bitget describes the November 5 announcement as the launch of a broader network. Its October documentation also showed that substantial parts of the institutional custody infrastructure were already available, so the launch is an expansion and formal positioning rather than the invention of third-party custody.
Separating Custody and Execution Does Not Eliminate Trading Risk
The model may reduce the need to move every asset onto an exchange-controlled wallet, but other exposures remain. Derivatives traders can still incur margin losses or liquidations, and custodians can face operational incidents or legal restrictions.
A trading venue can also experience outages, market dislocations or disputes over settlement obligations even when underlying assets remain externally held. The details of who can freeze, pledge or move assets should be established in each contractual arrangement.
Bitget did not publish a consolidated independently audited figure showing how much customer capital had already moved through the newly branded network by November 5.
Institutional Crypto Market Structure Continues to Evolve
The launch fits a broader shift toward separating asset safekeeping from market execution. BlockBriefing recently reported on UstarPay’s custody arrangement with BitGo, which concerns payments rather than exchange trading.
The distinction is important: trading collateral, custody of payment assets and insured bank deposits represent different legal and financial relationships.
For prospective users, the practical questions are which entities hold the assets, what happens if the trading venue fails, how collateral is valued and when settlement occurs. Those terms will determine whether Bitget’s Open Custody Network delivers the intended reduction in custody concentration risk.
