What It Is

4OTC is a London-based fintech company serving institutional clients worldwide. Its core business is not traditional payment acquiring, but low-latency connectivity infrastructure for FX and digital asset trading. Its services cover use cases such as exchanges, ECNs, OTC dealers, single-dealer banks, and more. Target customers include banks, market makers, buy-side trading firms, brokers, and liquidity providers.

Core Capabilities

Its main product lines include 1API, Libre, and TicketLounge. 1API provides a single interface for products including FX spot, forwards, NDFs, as well as digital asset spot, perpetuals, and futures, with integration via FIX or SBE API. Libre is a bridging tool for FX liquidity providers, designed to deliver Spot, Forwards, and NDF liquidity to exchanges with low latency. TicketLounge focuses more on post-trade processing, offering redundant, highly reliable STP services and supporting FX Spot, Forwards, Swaps, NDFs, NDF Swaps, as well as digital asset spot, perpetual swaps, and futures.

Pricing and Compliance

The website does not disclose specific pricing, rates, fees, or SLA details. It only mentions that users can contact sales and request a free trial of 1API. On the compliance side, the main text only explicitly states that TicketLounge supports MiFID2 and regulatory fields. It does not disclose any financial licenses or regulatory registrations for the company, so it should not be treated as a provider with specific payment or brokerage licenses.

Pros and Cons

Its strengths are its highly specialized positioning and strong low-latency capabilities, supported by co-location deployment, a global network backbone, and internal timestamping, making it easier for institutions to measure performance. The company claims clients can reduce latency by 30%-50% compared with building their own systems. A single API can also reduce the cost of connecting to multiple venues. The downside is limited disclosure: there is no detailed list of venues, pricing, regulatory licenses, SLAs, or implementation case studies, which makes cost assessment more difficult for smaller teams.

Best Fit and Access from China

4OTC is best suited to institutions that already have trading systems and technical teams, for use cases such as multi-venue access for FX and digital assets, market data/execution connectivity, liquidity distribution, and post-trade STP. It is not suitable for ordinary merchants looking for bank card, wallet, or local payment acquiring services. The main text does not state how well it works from mainland China. Actual network connectivity, compliance availability, and digital-asset-related restrictions need to be verified separately. Comparable alternatives include LMAX, Currenex, Integral, oneZero, Talos, and other institutional connectivity providers.
