Top-5 DeFi Protocols in 2025

·

The decentralized finance (DeFi) ecosystem continues to evolve rapidly, reshaping how users interact with digital assets through lending, staking, liquidity provision, and stablecoin innovation. As of 2025, several protocols have emerged as leaders in terms of total value locked (TVL), user adoption, and technological advancement. This article explores the top five DeFi protocols that are defining the future of blockchain-based finance.

Aave: The Pioneer of Decentralized Lending

Aave stands as one of the earliest and most influential DeFi protocols, maintaining its position as a market leader with over $18 billion in TVL as of April 2025. Originally launched in 2017 under the name ETHLend, the platform rebranded to Aave in 2018, transitioning from a peer-to-peer lending model to a more scalable system powered by liquidity pools and smart contracts.

Today, Aave operates as a non-custodial lending protocol where users can deposit supported cryptocurrencies into shared pools and earn interest—or borrow against their holdings by providing collateral. The platform supports a wide range of digital assets, including:

Interest rates on Aave’s credit pools vary based on supply and demand dynamics, ranging from 0.01% to 3.28% APY as of early 2025. These competitive returns, combined with robust security and cross-chain compatibility, make Aave a go-to platform for both retail and institutional participants.

The protocol is governed by its native AAVE token, introduced in October 2020. AAVE serves multiple functions: it enables governance through a decentralized autonomous organization (DAO), provides liquidity protection via a safety module, and rewards long-term stakeholders. With a market cap exceeding $2.03 billion, AAVE ranks among the top 40 cryptocurrencies globally.

Why Aave Stands Out

Lido: Leading the Liquid Staking Revolution

Launched in December 2020, Lido DAO—commonly known as Lido—has become the dominant force in liquid staking, particularly for Ethereum. As of April 2025, Lido secures nearly $15.2 billion in TVL, ranking second among all DeFi protocols.

Liquid staking addresses a key limitation of traditional staking: illiquidity. Instead of locking up ETH during the staking period, users deposit their ETH into Lido’s smart contract and receive stETH (staked ETH) tokens in return. These Lido-provided LP tokens represent ownership of staked assets and can be freely used across the DeFi ecosystem.

Use cases for stETH include:

Users earn an annualized yield of approximately 3.1% on their staked ETH through protocol-level rewards. This seamless integration of staking returns with DeFi composability has driven widespread adoption.

Lido’s governance is managed through its LDO token, distributed to early contributors and active participants. As of 2025, LDO holds a market capitalization of $609.5 million and ranks within the top 100 crypto assets.

“Liquid staking isn’t just about earning yield—it’s about unlocking capital efficiency across DeFi.”

Risks to Consider

While highly effective, liquid staking carries risks such as smart contract vulnerabilities and potential centralization concerns due to validator concentration. However, ongoing decentralization efforts aim to mitigate these issues over time.

EigenLayer: Powering the Re-Staking Economy

EigenLayer has emerged as the cornerstone of the re-staking movement, enabling users to extend the utility of already-staked assets. Built on Ethereum, EigenLayer allows holders of liquid staking tokens (LSTs)—like stETH or rETH—to re-stake them and secure additional networks, thereby earning extra yield.

With a TVL of $7.3 billion in April 2025, EigenLayer ranks third in the DeFi space. Its innovative approach introduces programmable trust, where Ethereum’s consensus security is reused to protect new protocols and middleware layers.

For example, a user who stakes ETH via Lido receives stETH. That stETH can then be deposited into EigenLayer to participate in node operation or validation for other services—earning around 4% APY in addition to base staking rewards.

The platform’s native token, EIGEN, launched in April 2024 and quickly gained traction. By April 2025, it reached a market cap of $186.2 million. EIGEN is used for governance, incentivizing node operators, and securing protocol upgrades.

EigenLayer is paving the way for modular blockchain architectures, where different components—data availability, execution, settlement—can leverage shared security infrastructure.

Sky Protocol: The Evolution of MakerDAO

Formerly known as MakerDAO, the platform rebranded to Sky Protocol in August 2024 following a major overhaul of its product suite and vision. The rebrand coincided with the launch of USDS, a new dollar-backed stablecoin designed for institutional-grade DeFi applications.

Sky Protocol’s TVL exceeds $6 billion, making it a critical pillar in the decentralized stablecoin landscape. Unlike centralized alternatives such as USDT or USDC, Sky issues Dai (DAI)—a decentralized stablecoin backed by a diversified basket of crypto and real-world asset (RWA) collateral.

DAI has consistently maintained its $1 USD peg, even during periods of extreme market volatility—a feat not achieved by failed projects like Terra’s UST or Waves’ USDN.

The ecosystem runs on two core tokens:

Sky’s integration of RWAs—such as treasury bonds and private credit—has enhanced collateral stability and attracted traditional finance players into DeFi.

Ethena: The New Era of Synthetic Yield

Ethena has rapidly ascended the DeFi rankings with nearly $5 billion in TVL by April 2025. Positioned as a next-generation stablecoin protocol, Ethena introduces USDe, a synthetically backed dollar-pegged token that does not rely on traditional reserves.

Instead, USDe uses delta-hedged ETH staking positions to generate yield while maintaining price stability. This innovative mechanism allows Ethena to offer users a sustainable 5% annualized yield on USDe holdings—significantly higher than most fiat-backed stablecoins.

USDe ranks as the fourth-largest stablecoin by market capitalization, trailing only USDT, USDC, and DAI. Its growth reflects increasing demand for yield-bearing digital dollars in DeFi.

The ecosystem also features the ENA token, launched in April 2024. ENA plays a dual role: enabling protocol governance and distributing bonus rewards to active users. With a market cap of $1.52 billion, ENA ranks among the top 50 cryptocurrencies.

Ethena exemplifies how DeFi innovation can combine capital efficiency, scalability, and user incentives in a single architecture.

Frequently Asked Questions (FAQ)

Q: What makes a DeFi protocol secure?
A: Security depends on audited smart contracts, decentralized governance, transparent codebases, and insurance mechanisms like liquidity buffers or bug bounties.

Q: Is liquid staking safe?
A: While convenient, liquid staking carries risks such as smart contract exploits and centralization of validators. Protocols like Lido are actively working to decentralize operations and improve resilience.

Q: How do I start using Aave or Lido?
A: Connect a Web3 wallet (e.g., MetaMask), deposit supported assets into the protocol via its official dApp, and begin earning yield or borrowing funds instantly.

Q: Can stablecoins like DAI or USDe lose their peg?
A: Yes, though well-designed systems include over-collateralization, arbitrage mechanisms, and emergency shutdowns to defend against de-pegging events.

Q: What is re-staking and why does it matter?
A: Re-staking allows users to reuse staked assets (like stETH) to provide security to other protocols. It amplifies capital efficiency but introduces new systemic risks if not properly managed.

Q: Are DeFi yields sustainable long-term?
A: Sustainable yields come from real economic activity—such as lending interest or staking rewards—not artificial inflation. Protocols like Aave and Ethena are designed with long-term yield models in mind.
