Meet Matt
I am a leading figure and highly experienced specialist litigator in complex and multi‑jurisdictional disputes involving blockchain technology and digital assets. My practice includes crypto asset recovery for individuals and businesses following a hack, scam or misappropriation, including matters where wrongdoers are unknown or outside the jurisdiction, as well as contractual disputes with digital assets at their core.
I have extensive experience obtaining urgent, bespoke injunctions, including worldwide freezing orders, search orders (such as Anton Piller orders) and specific disclosure orders, and I have advised in some of the leading cases in this sector. By developing clear legal strategies informed by the underlying technology, I have recovered millions of pounds’ worth of digital assets for clients.
My expertise has been recognised in the leading legal directories, most recently in the Crypto‑Asset Disputes section of Chambers and Partners’ FinTech Guide 2026.
My practice also includes commercial litigation and disputes concerning technology and intellectual property matters, including trade mark and copyright infringement relating to digital, artistic and technology‑focused works.
My active involvement in the industry includes a number of high‑profile external appointments:
Experience highlights
- AA v Persons Unknown [2019] EWHC 3556 (Comm) (Comm) (13 December 2019) where, following a ransomware attack, an insurer paid Bitcoin in return for a Canadian hospital’s access to its customers’ data. This case confirmed that Bitcoin and crypto assets broadly were ‘property’ at common law and helped shape much of the law surrounding the status and strategies in freezing and recovering crypto assets around the world. It is highly cited in academic papers and judgments globally.
- Advising a London hedge fund following the loss of c.2 million USDC, obtaining a worldwide freezing injunction and an Anton Piller order, and recovering funds in nine working days (Matt Green on Recovering $1.5M in USDC in Under Two Weeks: Legal “Nuclear Options” and Peer-to-Peer Strategy - Lawrence Stephens).
