Custody Services

Last Modified: October 27, 2016

In addition to being a next-generation digital asset exchange, Gemini is also a fully-licensed digital asset custodian and fiduciary. The New York State Department of Financial Services (NYSDFS) has chartered Gemini as a limited-purpose trust company and holds us to specific capital reserve requirements and banking compliance standards.

The vast majority of our customers’ digital assets are secured in our proprietary offline (i.e., air-gapped) storage system which we call “Cold Storage.” High-level technical details of Gemini’s Cold Storage system are described on our Security page.

We believe that Gemini is uniquely positioned to safeguard digital assets because of our attention to cryptographic and cyber security in addition to our oversight by one of the world’s premier banking regulators. Gemini now offers two state-of-the-art solutions for custodying digital assets:

Fees are charged on the last business day of every month and deducted from an account’s U.S. dollar or digital asset balance based on daily Gemini exchange rates.
