The rise of stablecoins has been nothing short of meteoric. Far from mere speculative instruments, stablecoins represent one of the few cryptocurrency products with a clear product-market fit (PMF). Industry forecasts predict trillions in stablecoin issuance could flood traditional financial systems (TradFi) within the next five years, signaling a seismic shift in digital finance.
Yet, not all that glitters is gold.
Behind the growth lies a quiet but critical retreat from one of crypto’s founding principles: decentralization. As scalability demands intensify and regulatory pressures mount, the original stablecoin trilemma—balancing price stability, decentralization, and capital efficiency—is being quietly rewritten.
The Evolving Stablecoin Trilemma
The foundational concept of the stablecoin trilemma once revolved around three core pillars:
- Price stability: Maintaining a consistent 1:1 peg, typically to the US dollar.
- Decentralization: No single point of control, enabling censorship resistance and trustlessness.
- Capital efficiency: Achieving stablecoin issuance without over-collateralization.
Historically, projects aimed to optimize all three. But in practice, trade-offs have become unavoidable. Today, many leading stablecoins have shifted focus—prioritizing scalability and regulatory compliance at the expense of full decentralization.

Modern iterations of the trilemma often replace "decentralization" with censorship resistance—a narrower, though still valuable, attribute. While censorship resistance ensures transactions can’t be blocked, it doesn’t guarantee full decentralization of governance, collateral management, or monetary policy.
Most newer stablecoins—even those built on decentralized exchanges (DEXs)—rely on centralized teams to manage yield strategies, collateral portfolios, and distribution. This central oversight resembles traditional corporate structures more than peer-to-peer networks. As a result, scalability stems from revenue generation rather than composability within DeFi ecosystems.
True decentralization remains elusive.
Why Decentralization Is Fading
The dream of a fully decentralized financial system has collided with harsh realities.
On March 12, 2020, amid global pandemic panic, cryptocurrency markets crashed. DAI, one of the most decentralized stablecoins at the time, broke its peg significantly. In response, MakerDAO gradually shifted its collateral base from volatile crypto assets to regulated fiat-backed stablecoins like USDC—effectively acknowledging the limits of pure decentralization under stress.
This pivot reflected a broader trend: institutional trust now favors regulated entities like Circle (USDC) and Tether (USDT). Their centralized operations allow faster intervention during crises, reinforcing market confidence—even if it undermines decentralization.
Meanwhile, algorithmic stablecoins like UST (Terra) and rebase models like Ampleforth failed to deliver sustainable stability. Regulatory scrutiny has only deepened since these collapses, making it harder for experimental models to gain traction.
Despite these setbacks, one project stands out for its commitment to decentralization: Liquity.
Built on Ethereum, Liquity uses immutable smart contracts and crypto-only collateral (ETH) to issue its stablecoin LUSD. With no governance tokens or admin keys, it represents one of the purest forms of decentralized stablecoin architecture.
Recently, Liquity launched V2, enhancing peg stability and introducing flexible interest rates for minting its new token, BOLD. These upgrades aim to improve capital efficiency and risk management.
However, Liquity faces structural challenges:
- Its loan-to-value (LTV) ratio caps at ~90%, lower than competitors offering 100% LTV.
- Rivals like Ethena (USDe), Usual (USDO), and Resolv (USR) offer higher yields via delta-neutral strategies and broader distribution.
- Limited distribution mechanisms restrict adoption beyond early Ethereum adopters.
- Minimal focus on DEX integration or retail use cases hampers mainstream scalability.
Despite a relatively modest total value locked (TVL), Liquity—and its forks—hold a combined TVL of $370 million, underscoring strong community trust in its model.
Regulatory Pressures and Institutional Shifts
Regulatory developments are accelerating the centralization trend.
Upcoming legislation in the U.S. and EU is expected to recognize only licensed, fiat-backed stablecoins issued by regulated entities. This effectively sidelines decentralized, crypto-collateralized, or algorithmic models—pushing them into regulatory gray zones or outright exclusion.
As a result, institutional-grade stablecoins like BlackRock’s BUIDL and World Liberty Financial’s USD1 are gaining momentum. These hybrid models aim to bridge TradFi and DeFi by tokenizing real-world assets (RWA), offering yield while maintaining compliance.
Similarly, Web2 giants like PayPal (PYUSD) are entering the space, leveraging their massive user bases to expand the total addressable market (TAM). However, their lack of deep DeFi integration limits composability and innovation potential.

Projects focused on yield generation—such as USDY (Ondo Finance) and USDe (Ethena)—use strategies like RWA staking or delta-neutral trading to generate returns. While effective, these models still rely on centralized teams for risk management and execution.
Even in DeFi-native projects, full decentralization remains theoretical. Most are better classified as on-chain derivatives than true stablecoins—controlled by core teams despite blockchain deployment.
Emerging Ecosystems and Future Hopes
New ecosystems like MegaETH and HyperEVM are revitalizing innovation.
Take CapMoney, for example: it begins with centralized decision-making but plans to transition toward decentralization using EigenLayer’s restaking mechanism for economic security. This phased approach balances control with long-term autonomy.
Forks of Liquity—like Felix Protocol—are also gaining traction. By targeting emerging blockchain networks and leveraging “novelty effects,” these projects achieve rapid growth and establish themselves as native-chain stablecoins.
Their success highlights a key insight: distribution strategy now outweighs pure decentralization in driving adoption.
The Core Challenge: Value Proposition vs. Distribution
Stablecoins are no longer just digital dollars—they’re financial instruments with embedded yield models, regulatory positioning, and ecosystem-specific utility.
But they share a common trait: centralized control.
Whether issuing against Treasuries (USDC), RWAs (USDY), or synthetic hedges (USDe), human teams make critical decisions. This centralization enables responsiveness and compliance but sacrifices censorship resistance and user sovereignty.
So what guarantees that a stablecoin is truly trustless?

Only fully decentralized models—like Liquity—can claim this. Yet their limited scalability keeps them niche.
Conclusion: Reaffirming the Original Trilemma
Centralization isn’t inherently bad. It brings simplicity, control, scalability, and regulatory alignment—critical for mainstream adoption.
But it diverges from crypto’s original ethos: user ownership, permissionless access, and resistance to censorship.
No centralized stablecoin can promise true asset sovereignty. Users hold digital claims—not direct ownership—on tokens controlled by third parties.
As we embrace innovation, we must not forget the foundational goals of the stablecoin trilemma:
- Price stability
- Decentralization
- Capital efficiency
The challenge ahead isn’t choosing two out of three—it’s finding ways to achieve all three without compromise.
Frequently Asked Questions (FAQ)
Q: What is the stablecoin trilemma?
A: The stablecoin trilemma refers to the challenge of simultaneously achieving price stability, decentralization, and capital efficiency in a single stablecoin design. Most projects optimize for two at the expense of the third.
Q: Why are most stablecoins becoming more centralized?
A: Centralization improves scalability, regulatory compliance, and crisis response. In volatile markets or legal environments, centralized control offers stability that decentralized systems often lack.
Q: Can a stablecoin be both scalable and decentralized?
A: It’s difficult but not impossible. Projects like Liquity show promise with immutable contracts and crypto collateral. However, achieving mass adoption without sacrificing decentralization remains an open challenge.
Q: Are algorithmic stablecoins dead after UST’s collapse?
A: Pure algorithmic models face skepticism post-UST. However, hybrid designs combining algorithms with over-collateralization or RWA backing are being explored as safer alternatives.
Q: What role do real-world assets (RWA) play in modern stablecoins?
A: RWAs like Treasury bonds provide yield and stability, making them attractive backing for institutional stablecoins. However, they introduce counterparty and regulatory risks that challenge full decentralization.
Q: Is USDC decentralized?
A: No. USDC is issued by Circle, a regulated financial entity. It’s backed by fiat reserves and subject to government oversight, making it centralized but highly trusted in traditional finance circles.
