Decentralized Finance is no longer a niche experiment. These protocols collectively secure hundreds of billions in user assets and process more daily volume than many mid-tier stock exchanges. Here are the top 10 DeFi protocols shaping Web3 in 2025, ranked by total value locked (TVL):
1. Lido Finance — Liquid Staking Dominance
TVL: ~$35B. Lido allows Ethereum holders to stake ETH and receive stETH (staked ETH) — a yield-bearing token that earns staking rewards (~3.5% APY) while remaining fully liquid. Lido controls over 28% of all staked ETH, making it systemically important to Ethereum’s security model.
2. Aave — Money Market Protocol
TVL: ~$12B. Aave is the largest decentralized lending protocol. Depositors earn yield; borrowers post over-collateralized positions. Aave v3 introduced cross-chain capabilities and Gas Mode (credit delegation). Supports 15+ chains including Ethereum, Avalanche, Polygon, Arbitrum, and Base.
3. EigenLayer — Restaking Infrastructure
TVL: ~$14B. EigenLayer pioneered “restaking” — allowing ETH stakers to simultaneously secure other protocols using the same staked ETH. This creates shared security for new blockchain services (called Actively Validated Services, or AVSs) without each needing their own validator set.
4. Uniswap — The DEX that Changed Everything
TVL: ~$6B. Uniswap invented the Automated Market Maker model that virtually every DEX now copies. Uniswap v4 (2024) introduced “hooks” — custom logic that fires before/after swaps, opens/closes, enabling unlimited customization by developers.
5. MakerDAO / Sky — The DAI Stablecoin Engine
TVL: ~$8B. The Maker protocol allows users to lock crypto collateral to mint DAI, a decentralized dollar-pegged stablecoin. In 2024, MakerDAO rebranded to Sky, introducing USDS (a successor to DAI) and SKY tokens. DAI remains the most trusted decentralized stablecoin with over $5B in circulation.
6. Curve Finance — Stablecoin Liquidity King
TVL: ~$2B. Curve is optimized for swapping assets that should trade at near-equal value — stablecoins, liquid staking tokens (ETH/stETH), and tokenized real-world assets. Its specialized AMM formula minimizes slippage for these asset types, making it essential DeFi infrastructure.
7. Pendle Finance — Yield Trading
TVL: ~$3B. Pendle allows users to split yield-bearing assets into principal tokens (PT) and yield tokens (YT), enabling fixed-yield strategies or leveraged yield speculation. It became the fastest-growing DeFi protocol in 2024 as LRT (liquid restaking token) yields exploded in popularity.
8. Compound — The OG Money Market
TVL: ~$1.5B. Compound was Aave’s main competitor and pioneered algorithmic interest rates. It also started the “yield farming” era by distributing COMP governance tokens to liquidity providers in June 2020. Though Aave has since surpassed it, Compound v3 remains a key protocol on Ethereum mainnet and several L2s.
9. dYdX — Decentralized Perpetuals
TVL: ~$0.4B (protocol) + ~$400M in open interest. dYdX pioneered decentralized perpetual futures trading with up to 20x leverage. Its v4 migration to a dedicated Cosmos-based blockchain enabled full decentralization — no reliance on Ethereum gas, no centralized sequencer.
10. Balancer — Programmable Liquidity
TVL: ~$0.9B. Balancer extends Uniswap’s concept to allow liquidity pools with up to 8 tokens and custom weighting. Its Weighted Pools allow a pool of 80% BTC / 20% ETH, for example. Balancer also underlies many other DeFi protocols through its boosted pool infrastructure.
Conclusion
These 10 protocols form the backbone of DeFi in 2025. Each represents a fundamental building block — lending, trading, stablecoin issuance, liquid staking, and yield trading. As with all DeFi, engage with these protocols carefully, understand the smart contract risks, and start with audited, well-established projects.
