Paxos Standard (PAX) vs Gemini USD (GUSD)

By zoplaska | learncrypto | 17 Dec 2019

While researching different stablecoins, I came across two stablecoins Paxos Standard (PAX) and Gemini USD (GUSD).  The purpose of the post is to look into similarity and differences between these two.


  • Both stablecoins are built by companies that registered in New York and approved and regulated by the New York Department of Finance (NYDFS).
  • As a regulated virtual currency by NYDFS, both are subject to the requirements as imposed by the New York Department of Finance.  These requirements states that:
    • Ensure that authorized stablecoins are fully exchangeable for a U.S. dollar.
    • Implement, monitor and update effective risk-based controls and appropriate BSA/AML and OFAC controls.
    • Implement, monitor and update effective risk-based controls to prevent and respond to any potential or actual wrongful use of stablecoin.
    • Maintain policies and procedures for consumer protection and to promptly address and resolve customer complaints.
  • Both companies have been issued a limited purpose charted by NYDFS.
  • Both companies have their holdings audited by a third party audit firm to confirm that the tokens in circulation are backed by equivalent US Dollar amount.
  • Both companies have their dollar holdings in a FDIC insured US financial organizations.
  • Both have their contract source code available online for public view.  PAX source code is available here and GUSD source code is available here.
  • Both are ERC-20 token based on Ethereum blockchain.

There are few differences that I would like to point out.


  • GUSD have their USD deposits at State Street Bank whereas PAX have their USD deposits in four various US financial organizations.
  • Total circulating supply for PAX is 237,866,083 PAX, whereas for GUSD it is only 4,029,624 GUSD.*
  • PAX is ranked 32 in terms of market cap.  GUSD is ranked 456.*
  • GUSD is audited by BPM LLP which is headquartered in San Francisco, CA.  PAX is audited by Withum LLP which is headquartered in Princeton, NJ.
