What Is Gemini Dollar (GUSD)?

The Gemini Dollar (GUSD) is a stablecoin issued by Gemini Trust Company, LLC, a New York-regulated cryptocurrency exchange and custodian. 

It was introduced in 2018 to bridge the gap between traditional flat currencies and decentralized finance (DeFi):

• Fully backed by U.S. dollars: Every GUSD token corresponds to one U.S. dollar held in State Street Bank.

• Built on Ethereum: GUSD follows the ERC-20 token standard, ensuring compatibility with DeFi platforms, smart contracts, and decentralized applications (dApps).

• Regulated and audited: Gemini adheres to strict regulations under the New York Department of Financial Services (NYDFS) and provides monthly audits by BPM LLP, a leading accounting firm.

• Programmable and scalable: GUSD can be used in automated transactions, smart contracts, and financial applications, making it highly scalable for institutional and retail users.

How Does Gemini Dollar (GUSD) Work?

GUSD operates on a transparent and verifiable financial model where a real U.S. dollar backs each token in a trust account. 

The issuance and redemption process follows a simple mechanism:

• Issuance: When a user deposits U.S. dollars into their Gemini account and converts them into GUSD, an equal amount of GUSD is minted.

• Usage: GUSD can be transferred, traded, or spent like any other cryptocurrency but with the added benefit of price stability.

• Redemption: Users can convert GUSD back into U.S. dollars anytime by withdrawing their funds from Gemini.

Because GUSD transactions are recorded on the Ethereum blockchain, they remain public, transparent, and verifiable.

GUSD Use Cases: Where Can You Use Gemini Dollar?

GUSD has a growing number of use cases:

1. Instant Global Payments

GUSD enables borderless transactions, allowing users to send U.S. dollars anywhere in the world within minutes. Unlike traditional banking methods, which involve long processing times and high fees, GUSD transactions occur 24/7 on the blockchain with minimal costs.

2. Earning Interest on Gemini Dollar (GUSD)

By holding GUSD on crypto lending platforms, users can earn interest rates of up to 9% per year, significantly higher than traditional bank savings accounts. Rates vary by platform and are not guaranteed.

3. Retail Payments

Some businesses accept GUSD for everyday purchases. In these cases, customers can seamlessly pay with GUSD at these stores using crypto payment processors.

4. Large Transactions and Tokenization

GUSD is increasingly being used for high-value transactions and asset tokenization. A notable example is its use in real estate security tokens, where investors receive dividends through blockchain-based assets.

Example: A real estate company in Brazil created security tokens backed by real estate assets, allowing investors to trade tokenized property shares using GUSD.

5. Trading on Decentralized Exchanges (DEXs)

GUSD can be swapped for other tokens on decentralized exchanges (DEXs) such as:

• Uniswap

• Curve Finance

• Balancer

This provides liquidity to the DeFi ecosystem while helping to maintain price stability.

6. Cross-Border Remittances 

GUSD simplifies international remittances, allowing users to send funds faster and cheaper than traditional banking services like Western Union or MoneyGram.

The Gemini Dollar Approach: Proof of Solvency

Each GUSD in circulation is fully backed by an equivalent U.S. dollar held in a Gemini Trust account, ensuring financial integrity and solvency.

For Every GUSD in Existence, Gemini Holds One U.S. Dollar

The primary stability factor of GUSD stems from its full backing by U.S. dollar reserves. Every GUSD in circulation corresponds to an equal dollar value that Gemini maintains within its reserves. 

State Street Bank operates as the financial institution that maintains U.S. dollar reserves — backing GUSD while being recognized for its strict regulatory compliance and strong security measures. The implemented structure helps GUSD maintain its role as a trustworthy, transparent digital asset.

A Public, Transparent Guarantee of Collateralization 

Gemini conducts third-party monthly audits to validate the U.S. dollar reserves that support GUSD. The BPM LLP, an independent accounting firm, conducts monthly audits of GUSD reserves and publishes public reports to verify full collateralization. 

The audits conducted by third parties verify that GUSD token supply aligns with the U.S dollar reserve holdings of Gemini. These examinations use standards created by the Official Attestation Standards from the American Institute of Certified Public Accountants (AICPA) to enhance Gemini's dedication to financial transparency.

The Ethereum Blockchain Distributed Ledger as a Verifiable Record

Through Ethereum blockchain integration, Gemini operates a decentralized system that publishes transaction data for all GUSD holdings. The Ethereum blockchain also operates a distributed ledger that publicly authenticates the total number of Gemini dollars issued. 

Users, regulators, and auditors can independently track the circulation of GUSD supply because the Ethereum ledger remains both immutable and transparent in real time. Through BPM verification, GUSD demonstrates fact-based accuracy, ranking it among the most reliable stablecoins in the market.

How Does GUSD Compare to Other Stablecoins?

Not all stablecoins offer the same level of transparency, security, and regulatory compliance. While Tether (USDT), USD Coin (USDC), and DAI are widely used, GUSD stands out as one of the most trusted stablecoins due to its strict oversight and financial integrity.

Regulations and Compliance 

Unlike USDT and DAI, which are not subject to the same degree of supervision, GUSD is fully regulated under the NYDFS, ensuring strict compliance with financial laws. USDC follows some regulations, but GUSD’s higher transparency and legal framework make it more secure.

Transparency and Audits

GUSD undergoes monthly third-party audits by BPM LLP, confirming that each token is fully backed by U.S. dollar reserves held at State Street Bank. USDT has faced legal scrutiny over undisclosed reserves, while USDC offers some transparency but lacks GUSD’s frequent audits.

Use Cases and Adoption

While USDT dominates trading volume, GUSD is accepted as a form of payment for several major retailers(AMC Theaters, Nordstrom), DeFi lending, and institutional trading. USDC is commonly used in DeFi, and DAI remains popular in crypto-backed lending, though less stable than fiat-backed alternatives.

Security and Stability 

GUSD employs a three-layer contract separation model for enhanced security and transaction efficiency. USDT has no verifiable security framework, USDC lacks GUSD’s level of contract security, and DAI is subject to crypto market fluctuations, making it less predictable.

GUSD is one of the few stablecoins with monthly third-party attestations and NYDFS oversight, offering a high level of transparency and regulatory compliance for both institutional and retail use.

How Does GUSD Maintain Security?

Security is a critical aspect of any cryptocurrency. Gemini has implemented multiple layers of protection to ensure GUSD remains secure and tamper-proof.

• Smart Contract Security: GUSD’s smart contracts undergo rigorous third-party audits before deployment. The contract includes fail-safes that allow for rapid response to vulnerabilities.

• Regulatory Oversight: Gemini Trust Company is regulated under the NYDFS, ensuring strict compliance with U.S. financial laws. GUSD follows the highest industry standards for fraud prevention and compliance.

The Gemini Dollar Contract Separation Model

Security, operational efficiency, and transparency within the Gemini Dollar (GUSD) protocol arise from its three independent but united operational layers. 

The contract separation model allows each layer to exercise specific operational roles, which prevents system failures and enables maximum performance. 

Proxy Layer: Governance and Transaction Authorization

The Proxy layer is designed to create and transfer GUSD using smart contracts. It also serves as a governance layer, overseeing transaction approvals and execution. In cases of security concerns or legal considerations, this layer provides a mechanism to stop GUSD minting and transfers, ensuring compliance and network integrity. 

The Proxy layer communicates with the implementation layer to determine which transactions should be executed.

Implement Layer: Smart contract Execution

The Implement layer (also referred to as “Impl”) is where the underlying programmatic logic and smart contract data are stored. Unlike the Proxy layer, which governs transactions, the Implement layer only executes pre-defined smart contract operations. Actions within this layer are only executed when instructions are received from the Proxy layer, maintaining a structured and secure process.

Store Layer: Distributed Ledger and Public Verification

The Store layer contains a distributed ledger and keeps track of specific balances held by each GUSD user. It acts as the final record-keeping layer, ensuring all transactions are published on the Ethereum blockchain. By leveraging Ethereum’s immutable and transparent ledger, this layer guarantees that GUSD transactions are permanently recorded and verifiable by anyone in the network.

These three layers work together to create a unique system that allows the Gemini Dollar to be efficient, transparent and equitable for all users on the Gemini platform. Each plays a critical role in ensuring GUSD’s accountability, security, ease of use, and ongoing technical innovation as the Gemini platform and Gemini Dollar usage continues to grow.
