BEST COMPANIES · RANKINGS
Blockchain and tokenization company rankings (2026)
Guides for choosing a tokenization, crypto custody or blockchain development provider, with each company's registration checked in an official source.
THE RANKINGS
How we build these rankings
Each ranking only names companies whose activity is described on their own website and whose registration, authorization or company record we checked in an official source: the CNMV, ESMA, BaFin, the SEC, FINRA BrokerCheck or a company register. Each ranking gives the date of that check and links to the source.
We do not use market-share figures, third-party rankings or volumes reported by the companies themselves. A registration shows that an entity exists or is authorized for a specific role; it is not an endorsement by any regulator and does not certify quality or solvency.
Unknown Gravity publishes these pages and appears first in each one, as a technology provider with no regulated status. The numbering is not a quality ranking.
