Rapid Addition and TradingStack Partner to Deliver Institutional-grade Connectivity to Global Digital Asset Markets

• Partnership with Rapid Addition enables TradingStack.io to extend its digital connectivity solution to high–performance FIX infrastructure.
• Rapid Addition partnership with TradingStack.io platform enables its customers to seamlessly integrate with key digital asset markets.

London, July 29, 2025 – Rapid Addition, a leading FIX connectivity solutions provider, today announces a partnership with TradingStack.io, experts in digital asset trading technology solutions to deliver institutional-grade connectivity to global digital asset markets.

Rapid Addition’s scalable trading workflow platform is capable of handling thousands of client connections and offers support for all versions of the FIX protocol, including custom tags and unique rules of engagement. The partnership will enable TradingStack to deliver high-performance FIX connectivity as part of its trading platform solutions to customers seeking access to global digital markets.

Capital markets institutions are increasingly exploring new opportunities presented by digital assets and tokenisation, primarily focused on unlocking efficiencies, improving asset liquidity, and future-proofing their trading infrastructure. Through issuing, managing, and trading tokenised versions of real-world assets—such as bonds, equities and funds—on distributed ledger platforms, firms can take advantage of faster settlement, enhanced transparency and fractional ownership.

This often requires integration with existing front-to-back trading workflows to avoid disruption of core systems or compliance processes. More specifically, firms need to bridge between established trading protocols such as FIX and new crypto venue interfaces, ensuring regulatory alignment, and maintaining enterprise-grade performance, security, and interoperability across traditional and digital asset systems.

The partnership is made possible as Rapid Addition’s and TradingStack’s platforms are both built on common high-performance, low-latency building blocks, such as the Aeron transport layer, enabling them to deliver high-throughput, institutional-grade connectivity to leading liquidity providers around the globe.

Mike Powell, CEO, Rapid Addition, said: “As traditional capital markets firms increasingly look to new trading and investment opportunities offered by cryptocurrencies and other digital assets, integration with existing infrastructure and systems is paramount to cost optimisation and operational efficiencies. We are therefore delighted to work with TradingStack.io to integrate our asset class agnostic platform with their digital asset trading solutions, providing our mutual customers with faster time to market and seamless connectivity to digital markets.”

Tim Connolly, MD, TradingStack, said: “As traditional buy-side and sell-side firms look to extend their offering to digital assets, they can avoid the operational burden of managing multiple fragmented systems, connections, and integrations across exchanges, custodians and service providers. TradingStack enables them to trade digital assets with the same efficiency, compliance, and control as traditional assets, reducing internal development costs and accelerating time to market.
