The United Kingdom concentrates institutional custody, chain analytics and liquidity firms, leaning on its existing financial infrastructure. Mandatory registration with the regulator for cryptoasset activity has been notably selective, and a number of applications were rejected or withdrawn.
What to compare: Entries here tend to be financial services businesses rather than protocol teams, with the compliance obligations that implies.
