ht.digital

HT Digital is a London-based professional services firm for digital assets, carved out in 2023 from Harris and Trotter, which was founded in 1940. It covers audit and assurance, tax and bookkeeping, independent management of foundations and DAOs, and on-chain reserve verification. It built a reconciliation system for validating market-maker revenue, automated proof-of-reserve tooling and reporting dashboards for DAOs, replacing audit sampling with recomputable on-chain reconciliation.

Clients include exchanges, market makers, custodians and token foundations, with coverage across the United Kingdom, the United States, the European Union, Switzerland and the Cayman Islands. In November 2025 Bridgepoint acquired a majority stake. As three crypto-asset tax reporting frameworks take effect, the firm has made digital asset tax compliance a standalone line, helping platforms complete data mapping and evidence retention before the first reporting cycle.
