TP ICAP’s institutional crypto venue Fusion Digital Assets has added a new direct route for market makers to stream spot-crypto liquidity into its order book, as the platform expands beyond Bitcoin and Ether and moves closer to weekend trading.
Connectivity provider 4OTC said on October 5 that its Libre Liquidity Bridge has been integrated with Fusion Digital Assets, allowing liquidity providers to distribute prices and route orders to the venue without having to develop their own dedicated exchange API connection.
The integration is designed to make it easier and faster for professional market makers to connect to Fusion, potentially lowering one of the technical barriers involved in adding new institutional liquidity to an electronic venue.
4OTC specializes in low-latency infrastructure across digital assets and foreign exchange. Its Libre service sits between liquidity providers and trading venues, handling connectivity, price distribution and order routing rather than requiring every firm to build and maintain a separate connection.
For TP ICAP, the significance goes beyond a technology integration. Fusion Digital Assets is simultaneously broadening the assets it plans to support and extending the trading schedule of a venue originally designed around the operational conventions of traditional wholesale markets.
Liquidity Providers Can Connect Without Building a Fusion API
The immediate benefit of the 4OTC connection is relatively straightforward.
A market maker that already uses Libre can connect its pricing infrastructure to Fusion Digital Assets through the bridge instead of undertaking a separate exchange-integration project.
Chay Pollard, TP ICAP’s Director of Digital Assets Electronic Broking, said the service allows liquidity providers to access Fusion without doing exchange API development work, making connectivity faster and more scalable.
That matters because institutional liquidity is partly a technology problem. A venue can attract interested trading firms, but every additional API, market-data feed, order protocol, certification process and operational workflow creates integration costs.
Reducing those costs can make it easier to add more market makers, which in turn can improve depth and competition inside the order book.
Fusion already supports its own FIX connectivity and integrations with institutional trading systems including Talos, Wyden, FlexTrade and others. 4OTC adds another route aimed specifically at firms distributing liquidity across multiple FX and digital-asset venues.
TP ICAP Sits Between Both Sides of Every Trade
The more important structural change at Fusion happened earlier this year when TP ICAP shifted the venue to a matched-principal model.
Under that structure, buyers and sellers do not directly face each other for settlement. TP ICAP becomes the counterparty to both sides of the transaction.
Institutional clients trade within assigned credit limits rather than having to deposit crypto or cash onto the venue before every transaction. Execution and settlement are separated, with clients able to settle from their preferred custody provider through a delivery-versus-payment process managed by TP ICAP.
That is a meaningful difference from the prefunded model that became standard across much of the crypto-exchange industry.
Prefunding reduces an exchange’s credit exposure because customers put assets on the platform before trading. But for banks, hedge funds and large market makers, it can also leave capital fragmented across multiple venues and create additional exchange-custody exposure.
TP ICAP is effectively trying to import a familiar wholesale-market framework into spot crypto: establish a credit relationship, trade first and settle afterward through institutional infrastructure.
The group said the same matched-principal framework processed more than $200 trillion of notional activity across its traditional markets in 2025. That figure relates to TP ICAP’s broader matched-principal operations rather than Fusion itself, but it explains why the company views the structure as established infrastructure rather than a crypto experiment.
SOL, USDC and More Fiat Pairs Are Next
Fusion’s product range is also widening.
The venue currently lists Bitcoin and Ether as live spot assets. TP ICAP says Solana, XRP and Circle’s USDC are coming next, alongside additional fiat and on-chain FX support.
USDC is particularly relevant because stablecoins are increasingly becoming financial infrastructure rather than simply settlement tokens used by crypto traders.
Adding a major regulated dollar stablecoin gives institutional users another potential settlement and trading asset while moving Fusion closer to the intersection between conventional FX and blockchain-native money.
The longer-term roadmap goes further. TP ICAP says the platform is being built to support tokenized real-world assets as those markets develop.
That puts Fusion into the same broader shift already visible in tokenized securities and other real-world assets, where blockchain infrastructure is increasingly being used for products that historically traded entirely within conventional financial systems.
Weekend Trading Is the More Important Next Step
The operating-hours roadmap may ultimately matter more than adding another cryptocurrency.
4OTC’s announcement says Fusion is extending its schedule from 23 hours a day, five days a week to continuous weekday trading, with weekend coverage expected afterward as client demand grows.
TP ICAP’s current product page already describes Fusion as operating 24/5, suggesting the continuous-weekday rollout is either underway or has been reflected in the venue’s latest public product information.
The remaining structural gap is therefore the weekend.
Closing that gap would move Fusion closer to the native rhythm of crypto itself. Bitcoin, Ether and Solana do not stop trading because London or New York has reached Friday evening. Crypto-native exchanges operate continuously, while much of the institutional infrastructure surrounding them still carries working-week conventions inherited from traditional finance.
That tension is appearing elsewhere. DaveFinances recently examined how Robinhood is pushing toward weekend trading in U.S. equities, while crypto exchanges are moving in the opposite direction by importing traditional assets into always-open environments.
Even Binance is using blockchain rails to offer 24/7 tokenized stock trading outside conventional market hours.
Institutional Crypto Is Starting to Look Less Like a Crypto Exchange
This is where the 4OTC announcement becomes more interesting than the integration itself.
Fusion increasingly looks less like an attempt to build another centralized crypto exchange and more like an effort to make digital assets fit into institutional market plumbing.
The distinction matters.
Crypto-native exchanges historically solved liquidity by asking participants to send assets to the exchange, maintain balances there and trade continuously inside a vertically integrated platform that often handled execution, custody and settlement together.
TP ICAP is taking almost the opposite approach.
Execution sits on an institutional central-limit order book. Clients can keep custody relationships elsewhere. TP ICAP intermediates the trades using credit limits. Settlement is handled separately. External technology vendors connect liquidity providers into the venue.
That architecture will look familiar to firms already trading FX, fixed income or other wholesale products.
And that familiarity may be more valuable to institutional adoption than adding hundreds of tokens.
24/7 Trading Creates Costs as Well as Opportunities
Moving from 23/5 to 24/5 sounds like a minor operational change. Moving from weekdays to seven-day trading is not.
A genuinely continuous institutional venue needs market makers, settlement processes, custody infrastructure, compliance monitoring, risk staff and technical support available when traditional financial institutions are normally least staffed.
Liquidity quality matters too.
Being open on Saturday does not automatically mean there will be deep institutional markets on Saturday. If fewer market makers are active, spreads can widen and order books can become easier to move.
TP ICAP therefore has a reason to expand gradually. The technology can operate continuously, but the surrounding ecosystem must be able to support the same standard of execution and settlement throughout the additional hours.
The 4OTC integration helps with one piece of that puzzle by reducing the work required for liquidity providers to participate.
The Real Competition Is Becoming Infrastructure, Not Token Count
For years, crypto exchanges competed visibly on listings, leverage and fees.
Institutional competition is moving somewhere less flashy.
The differentiators are increasingly credit efficiency, counterparty quality, custody choice, liquidity connectivity, settlement reliability and how easily a trading desk can plug the venue into infrastructure it already uses.
Fusion surpassed $1 billion in monthly notional trading volume across its Bitcoin and Ether books in 2025. That is still modest beside the largest global crypto exchanges, but raw volume is not necessarily the best metric for what TP ICAP is building.
The stronger test will be whether additional market makers connect, whether SOL and USDC attract meaningful flow, and whether the matched-principal structure persuades institutions that previously disliked prefunding crypto exchanges to participate.
Then comes the weekend.
If Fusion eventually provides institutional credit, traditional counterparty protections and deep liquidity seven days a week, it will represent something more significant than another crypto venue extending its opening hours.
It would show traditional wholesale market infrastructure adapting to a market that never learned how to close.
