How Many Stablecoins Are There?

·

The stablecoin landscape has evolved dramatically since its inception, growing from a niche experiment into a cornerstone of the digital asset economy. With 213 stablecoin projects announced since 2014, the space has seen waves of innovation, speculation, and consolidation. As of 2019’s first quarter, momentum continues—albeit at a more measured pace—with 20 new projects emerging. This article explores the current state of stablecoins, their types, viability, and future potential, offering a comprehensive overview for investors, developers, and crypto enthusiasts.

Stablecoin Ecosystem Overview

Of the 213 tracked stablecoin projects:

This distribution highlights both the promise and peril in the stablecoin space. While demand remains strong—hovering around $3 billion since mid-2018—many projects fail to launch or sustain operations. The most resilient models are those backed by transparent, real-world assets.

Collateralized Stablecoins: Off-Chain Models

The majority of stablecoins rely on off-chain collateral—real-world assets held by centralized entities. These are further categorized by asset type.

Fiat-Collateralized Stablecoins (63 Projects, 32 Live)

Fiat-backed stablecoins dominate the market due to their simplicity and ease of understanding. Each token is typically backed 1:1 by USD or another major currency held in reserve. Redemption works like an IOU: users deposit cash, receive tokens; when they redeem, tokens are burned.

Transparency is critical. Regular audits and attestations help build trust—but aren’t foolproof. Past incidents involving Tether underscore the risks of opaque reserves.

Notable live projects include:

Interest is rising in non-USD pegs. While Euro-backed options were once limited to STASIS and BitShares, new entrants like TrustToken and Universal Protocol are expanding access to EUR-pegged digital assets.

Gold-Collateralized Stablecoins (47 Projects, 9 Live)

Gold-backed stablecoins aim to merge precious metal value with blockchain efficiency. Each coin represents ownership of physical gold stored in vaults, ideally at a 1:1 ratio.

However, this sector is riddled with red flags:

Live examples:

Given the speculative nature and high operational costs, these tokens struggle as practical mediums of exchange.

Commodity-Backed Stablecoins (12 Projects, 3 Live)

Beyond gold, some ventures use silver, oil, or even diamonds as collateral. ARG3NTUM, for instance, is backed by silver reserves.

Diamond-backed models face particular challenges:

These assets lack the fungibility needed for reliable price stability.

Multi-Collateral & Hybrid Models (5 Projects, 1 Live)

Some stablecoins are backed by diversified baskets of currencies and commodities. Globcoin, the only live project in this category, pegs its value to a composite index, offering flexibility and reduced exposure to single-asset volatility.

Another approach uses the IMF’s Special Drawing Right (SDR), a reserve asset based on a basket of major currencies. Such models could appeal to institutions seeking macroeconomic resilience.

Projects With Unclear Collateral (4 Projects, 1 Live)

A small group of projects lacks public documentation on their backing mechanism. Dukascoins by Dukascopy Bank is live but offers limited transparency—assumed to be fiat-backed due to its banking origin.

Without clear disclosures, these projects pose higher risk and hinder market trust.

On-Chain Collateralized Stablecoins (33 Projects, 15 Live)

This category represents a shift toward decentralization. Instead of trusting third-party custodians, these stablecoins use blockchain-based collateral—primarily crypto assets like ETH or BTS.

Key Examples:

These models eliminate counterparty risk but introduce volatility risk—if the underlying crypto asset crashes, the peg may break unless over-collateralized.

Algorithmic Stablecoins (26 Projects, 2 “Not Dead Yet”)

Algorithmic stablecoins attempt to maintain price stability without any collateral—using smart contracts that expand or contract supply like a central bank.

Despite theoretical appeal, real-world results have been poor:

Challenges include:

Still, at least 19 teams continue research in this space—indicating belief in long-term potential.

Market Demand and Peg Preferences

Total market capitalization for stablecoins has remained relatively stable at $3 billion since mid-2018. Of the 62 live projects:

The USD’s dominance reflects its global reserve status—even in decentralized ecosystems. There’s no sign of anti-dollar sentiment; instead, competition centers on who can best replicate dollar stability with greater transparency and efficiency.

Tether (USDT) remains the market leader—but faces increasing pressure from regulated alternatives like USDC and GUSD.

Governments and Central Bank Digital Currencies (CBDCs)

While private stablecoins grow, governments are advancing their own digital currencies. According to the Bank for International Settlements (BIS), 70% of 63 central banks surveyed are exploring blockchain-based money.

Potential government-backed coins include:

These could disrupt private stablecoins by offering state-guaranteed stability and broader acceptance. However, they also raise concerns about privacy and financial control.

Public sector involvement validates the importance of digital money—but also intensifies competition.

Frequently Asked Questions

What is a stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value relative to a real-world asset, usually a fiat currency like the US dollar or euro.

Which stablecoin is the most widely used?
Tether (USDT) is currently the most traded stablecoin by volume and market cap.

Are all stablecoins backed by real assets?
No. While many are backed by fiat or commodities, algorithmic stablecoins use code-based mechanisms instead of collateral.

Why do most stablecoins peg to the US dollar?
The USD is the world’s primary reserve currency, making it a natural benchmark for stability and international trade.

Can stablecoins lose their peg?
Yes. Even well-designed stablecoins can de-peg during extreme market stress or loss of confidence—especially if reserves are insufficient or opaque.

What role do stablecoins play in DeFi?
They provide liquidity, act as pricing oracles, and enable leveraged trading without exposure to crypto volatility.

Stablecoins are foundational to the future of digital finance. Whether backed by fiat, crypto, or algorithms, their success hinges on transparency, reliability, and trust. As innovation continues—and competition intensifies—the path forward will favor those who prioritize accountability and user protection.
