Regulatory expertise for digital and crypto asset firms

We provide specialist digital assets compliance support for crypto and digital asset firms navigating the UK’s evolving regulatory landscape. With the FCA expanding its oversight of cryptoassets beyond anti-money laundering registration to a full authorisation regime, firms face increasingly demanding compliance requirements.

Drawing on direct experience at leading digital asset firms including OKX and Copper Technologies, we understand the operational complexity and regulatory challenges facing exchanges, custodians, and staking providers.

Sector Overview

Digital asset firms in the UK now operate under multiple overlapping regulatory frameworks. The cryptoasset financial promotions regime requires clear, fair and not misleading communications, while current AML registration and forthcoming authorisation requirements demand robust systems and controls. In addition, firms holding client assets must prepare for the application of CASS-style safeguarding requirements.

Whether you operate an exchange, custody provider, staking service, or tokenisation platform, our digital assets compliance expertise helps you meet regulatory expectations while building for growth.

Sector-Specific Challenges

Investment platforms we work with commonly face:

  • Preparing for the new FCA cryptoasset authorisation regime
  • Meeting financial promotions requirements for cryptoasset marketing
  • Implementing robust AML systems, controls and governance
  • Developing safeguarding arrangements for client cryptoassets
  • Building operational resilience for critical business services
  • Applying Consumer Duty principles to retail crypto customers
  • Managing regulatory change as the UK framework evolves

We help firms tackle these challenges proactively, so that compliance supports rather than hinders business development.
