The United Kingdom and the United States are in early talks to create a shared crypto testing space known as a “sandbox.” The goal is to help both countries align their approach to digital asset rules and licensing.
Lisa Cameron, founder of the UK-US Crypto Alliance and former British lawmaker, revealed that her organization believes discussions for a joint crypto sandbox are already underway. She shared the update during a meeting at the United Nations offices in Copenhagen.

According to Cameron, the sandbox could make it easier for companies to operate across both markets under one set of standards. This is a system known as “passporting.” It would allow licensed crypto firms in one country to serve customers in the other without applying for new permits.
Talks Build on Ongoing Cooperation
The idea of a shared sandbox comes as both governments step up cooperation on digital assets. Earlier this year, the UK and US treasury departments formed a transatlantic task force to study short-term joint projects in crypto regulation.
At the same time, the Bank of England proposed new rules for stablecoins tied to the British pound. The plan would give regulators more control over how these tokens are used in payments, mirroring moves seen in the US.

Cameron said that conversations with American senators and members of the US Securities and Exchange Commission’s crypto task force inspired optimism about closer ties between the two nations.
Pressure Builds for the UK to Act Fast
Despite progress, Cameron warned that the UK could fall behind if it delays. Many startups, she said, are leaving for countries with clearer rules and stronger government support.
She noted that the United States has shown firm direction on emerging technologies, while Britain is still debating its stance. “The window of opportunity will not stay open forever,” she said.
For both countries, a joint sandbox could mark a major step toward global crypto standards turning competition into cooperation in one of finance’s fastest-moving frontiers.
