• Demonstrable experience working with blockchain analytics and forensic tools, with a sound understanding of their application to AML/CFT obligations, transaction monitoring programmes and on-chain investigations within a regulated financial services context.
• Strong track record evaluating risks associated with third-party blockchain infrastructure, cross-chain interoperability protocols (bridges) and smart contract audit processes, including the assessment of automated on-chain settlement workflows such as Delivery versus Payment (DvP) and Payment versus Payment (PvP).
