Introduction

Gemini dollar (GUSD) is a fiat-backed stablecoin that brings the stability of the U.S. dollar onto the Ethereum blockchain. It was designed to combine dollar-level price certainty with the speed, transparency, and programmability of crypto.

GUSD holds the distinction of being one of the world's first stablecoins to receive approval from a U.S. regulatory body, setting a benchmark for compliance in the stablecoin space.

History & Background

Gemini Trust Company was founded in 2014 by Cameron and Tyler Winklevoss as a licensed digital currency exchange and custodian. In September 2018, Gemini received approval from the New York State Department of Financial Services (NYDFS) to launch GUSD, making it one of the earliest regulated stablecoins in the world.

Since launch, GUSD has expanded its presence across DeFi protocols, exchanges, and payment platforms.

How Gemini dollar Works

GUSD operates as an ERC-20 token on Ethereum. Its smart contract architecture uses a three-layer separation model — Proxy, Impl (implementation), and Store — which enhances security and upgradability without disrupting user balances.

When a user deposits U.S. dollars on the Gemini platform, an equivalent amount of GUSD is minted. When GUSD is returned to Gemini, it is burned and the corresponding dollars are redeemed. This minting-and-burning mechanism keeps the peg intact at all times.

Smart contracts are audited by Trail of Bits, a reputable blockchain security firm.

Tokenomics

GUSD follows a fully collateralized issuance model. Every token in circulation is backed 1:1 by U.S. dollar reserves held in segregated accounts at regulated institutions including State Street Bank, Goldman Sachs, and Fidelity.

Reserves are held in cash, money market funds, and U.S. Treasury obligations. Because the token supply expands and contracts with user demand, GUSD has no fixed issuance schedule — it is purely demand-driven.
