Lido launched on Ethereum in December 2020 as a liquid staking protocol. Users deposited ETH, received stETH (a tokenized representation of their staked position), and could use stETH across DeFi while still earning staking rewards. The product was so obviously useful that it grew explosively. Within two years Lido controlled more than 30% of all staked ETH — a level that triggered serious concerns about validator centralization.

The centralization problem was real. Ethereum’s security model depends on no single entity controlling too large a share of validators. Lido’s growth raised legitimate questions about whether DeFi had accidentally created a new point of centralized control over Ethereum consensus. The Lido team responded by expanding its node-operator set, but the underlying tension between protocol scalability and decentralization never fully resolved.

stETH became one of the most-used collateral assets in DeFi. Aave accepted it, Compound eventually did too, and yield strategies built around stETH generated billions in flows. During the 2022 crisis, stETH briefly depegged from ETH as users panicked and tried to exit their staked positions, creating temporary arbitrage opportunities but also genuine systemic risk. Lido survived. The LDO token never fully captured value the way some hoped, but the protocol itself became load-bearing infrastructure for the Ethereum ecosystem.

Lido’s legacy is complicated. On one hand, it made staking accessible to retail users who couldn’t run their own validators, democratizing participation in Ethereum consensus. On the other hand, it created a concentration of stake that many Ethereum core developers still consider dangerous. The story is unresolved, and whether Lido is remembered as DeFi’s greatest success or its biggest centralization risk depends on how the next few years of Ethereum validator dynamics unfold.

Curve Finance launched in 2020, built by Michael Egorov, a Russian physicist and quant. Its innovation was the Stableswap algorithm — an AMM specifically optimized for assets that should trade near the same price, like USDC/USDT or different ETH variants. Before Curve, swapping stablecoins through Uniswap caused significant slippage. Curve eliminated that, and by 2021 it was processing billions in daily volume for stablecoin swaps alone.

Curve’s governance design (veCRV, vote-escrowed CRV) triggered the infamous “Curve Wars” of 2021-2022. Protocols including Convex, Yearn, and StakeDAO competed to accumulate CRV and direct emissions to their preferred pools. Convex won decisively, accumulating more CRV than any other entity and becoming a kind of meta-governance layer for Curve. The whole dynamic was dizzyingly complex and became a case study in token-based governance in DeFi.

The near-death experience came in July 2023 when a Vyper compiler bug caused multiple Curve pools to be drained for $70 million. The exploit exposed an existential risk: Curve’s founder had personally taken out loans against CRV collateral, and a cascading liquidation of his position threatened to send CRV to zero and potentially bankrupt much of DeFi. A coordinated OTC rescue operation saw whales purchase Egorov’s CRV directly, preventing the crash. It was one of the stranger moments in DeFi history — a founder’s personal leverage nearly destroying a major protocol.

Curve survived. By 2024 it was again one of the largest stablecoin swap venues, had launched crvUSD (its own stablecoin), and had expanded to multiple chains. The protocol’s durability through multiple existential threats — exploits, founder risk, Curve wars drama — is itself a testament to how important its core function is. Stablecoin swaps are boring infrastructure, but somebody has to do them, and Curve still does it better than almost anyone else.

Uniswap v1 launched in November 2018, built by Hayden Adams, a mechanical engineer who had just been laid off from Siemens and taught himself Solidity. The protocol implemented a simple constant-product AMM formula that Vitalik Buterin had casually described in a forum post. Adams’s contribution was turning that idea into working code. The result became the most important DeFi protocol ever built.

Uniswap v2 launched in May 2020 and kicked off DeFi Summer. Anyone could list a token without permission. Anyone could provide liquidity and earn fees. The design was so simple and so composable that it became the base layer for almost everything else in DeFi. YAM, SushiSwap, and countless forks tried to capture Uniswap’s liquidity during the fair-launch craze. Uniswap survived and dominated.

Uniswap v3 in 2021 introduced concentrated liquidity, letting LPs specify price ranges for their liquidity. It was a massive technical leap and completely changed LP economics. Uniswap v4, shipping in 2024, added “hooks” — programmable extensions that let developers customize pool behavior at the contract level. Each version pushed the state of the art forward, and each version was widely copied.

By 2025, Uniswap had done over $2 trillion in cumulative volume across all versions, was deployed on more than a dozen chains, and had launched Unichain, its own L2 on Optimism’s stack. The UNI token remained one of the largest governance tokens in DeFi despite lacking direct fee capture (a long-running community debate). Hayden Adams, the once-unemployed mechanical engineer, became one of the most important people in crypto. The entire category of AMM-based DEXs exists because he shipped a simple formula, and DeFi wouldn’t exist without him.

Pendle launched in 2021 as a yield-trading protocol — a niche product for sophisticated DeFi users who wanted to separate the yield stream from the principal of an asset. Deposit stETH, receive PT-stETH (the principal) and YT-stETH (the yield). Trade them separately. Speculate on future yields. Lock in fixed rates. It was clever, technically sophisticated, and for its first two years, extremely niche.

Then 2024 happened. The EigenLayer restaking craze created an environment where users wanted to speculate on future points airdrops. Pendle became the default venue for this: by tokenizing yield streams from eETH, ezETH, rsETH, and other liquid restaking tokens, Pendle let users get leveraged exposure to points programs without directly providing the underlying capital. TVL exploded from under $500M to over $5B in months. The PENDLE token, which had been trading in the low cents for years, rallied to over $7.

Pendle’s founders, TN Lee and a small team originally based in Vietnam, had spent years waiting for the right market conditions. Their patience paid off. By mid-2024 Pendle was one of the most-mentioned protocols in Crypto Twitter, with entire yield farming strategies built around its markets. The team shipped constantly, adding new asset types, better UX, and expanded chain support.

The lesson of Pendle is about timing and persistence. Yield trading as a concept had existed in TradFi for decades. The DeFi version was clear but underused until the right catalyst — points programs — made it suddenly essential. The Pendle team could have pivoted or shut down during the years when TVL was flat. Instead they kept building, and when the wave came they were the only ones positioned to ride it. In crypto, that kind of quiet durability is rare, and when it’s rewarded, the rewards are enormous.

Hyperliquid launched in 2023 as a perpetual futures DEX built on its own custom L1, designed from the ground up for sub-second orderbook execution. The founders — Jeff Yan and iliensinc, both Harvard grads with HFT backgrounds — had worked at Hudson River Trading and understood what real execution quality looked like. Their bet: everyone else building perps had accepted bad UX because decentralized orderbooks were hard. They would just build the hard thing.

The bet worked. By mid-2024, Hyperliquid was processing more than $1 billion in daily perpetual volume, competing directly with centralized exchanges like Binance for serious derivatives traders. Its points program, which ran for more than a year without any token, became the single most-discussed airdrop campaign in crypto. Users deposited hundreds of millions chasing Hyperliquid points with no certainty the token would ever exist.

On November 29, 2024, Hyperliquid finally airdropped the HYPE token. The allocation was unprecedented: 31% of total supply, with no VC allocation, no team lockup for early users, and no exchange listing fees paid. Over 94,000 wallets received tokens. HYPE opened around $3 and ran to over $35 within weeks, briefly making Hyperliquid’s fully diluted value exceed $30 billion — a number that put it among the top ten crypto assets by FDV.

What makes Hyperliquid historically significant is that it proved the no-VC, product-first, community-owned model could actually win. The team turned down multiple funding rounds during the bear market. They kept shipping. They aligned incentives with users instead of investors. And they built a better product than anyone else had managed to build in the perp DEX category. The industry noticed. Every protocol launching in 2025 was suddenly trying to copy the Hyperliquid playbook, and most of them were failing to do so.

GMX launched on Arbitrum in September 2021, introducing the GLP pool model that would influence every subsequent perp DEX design. Instead of an orderbook, traders traded against a shared liquidity pool (GLP) composed of ETH, BTC, and stablecoins. Liquidity providers earned trading fees, funding rates, and a share of liquidations. It was elegant, capital-efficient, and novel.

At its peak in late 2022, GMX was the largest source of revenue on Arbitrum and one of the top-earning protocols in all of DeFi, generating $200M+ in annualized fees. The GMX token accrued 30% of fees directly to stakers in ETH, creating one of the first real-yield models in DeFi. Analysts called it “the Berkshire Hathaway of perps.” For about a year, that comparison felt earned.

Then the problems started. The GLP model worked beautifully in trending markets but created toxic flow problems when traders consistently won against the pool. Hyperliquid, dYdX, and other orderbook-based competitors ate into GMX’s market share. An exploit in 2024 drained tens of millions from a GMX v1 pool. The v2 upgrade addressed some issues but never recaptured the momentum. By late 2024, GMX was a respected but shrinking player.

GMX’s historical importance isn’t its current state — it’s that it pioneered real-yield DeFi tokenomics and the pool-based perp design. Dozens of forks and imitators followed: Gains Network on Polygon, Vertex, Kwenta, Level Finance, and others. The concept that LPs could be the counterparty to traders, and that tokens could accrue direct fee revenue without inflation games, traces back to GMX. Even as competitors surpassed it, GMX’s ideas became the foundation for much of modern DeFi thinking about tokenomics.

dYdX launched in 2017 as one of the earliest DeFi protocols, founded by Antonio Juliano, a former Coinbase engineer. It started as a margin trading protocol on Ethereum, then pivoted to perpetual futures, and by 2021 was the largest decentralized derivatives venue in crypto. At its peak during the 2021 bull market, dYdX was doing billions in daily volume, rivaling centralized exchanges.

The defining moment came in 2022 when Juliano announced dYdX v4 — a complete rebuild on its own Cosmos-based L1 chain. The move was controversial. Many users were happy with the StarkEx L2 solution dYdX had been using. Moving to a new chain meant new infrastructure, new wallets, and a migration process that would inevitably lose some users. Juliano argued it was necessary for true decentralization: the orderbook would move fully onchain, validators would become essential infrastructure, and dYdX would stop being reliant on centralized order matching.

The migration to dYdX v4 happened in late 2023. Volumes dropped significantly during the transition as Hyperliquid and GMX absorbed some of the flow. But dYdX has steadily climbed back, and by 2025 it was again one of the top three decentralized perpetual venues by volume. The DYDX token saw significant changes — fees now accrue to stakers directly, and the token has more direct value capture than the original Ethereum-based version.

dYdX’s lesson is about the cost and value of decentralization. Centralized-enough DeFi protocols can be faster and more capital-efficient, but they compromise on the original crypto values. Fully decentralized protocols have worse UX and need to bootstrap infrastructure from scratch. Juliano bet that the long-term right answer was full decentralization — and that the short-term pain of the migration would be worth it. The jury is still out, but dYdX is one of the few protocols that actually walked the decentralization talk instead of just tweeting about it.

Aave started as ETHLend in 2017, a peer-to-peer crypto lending platform founded by Stani Kulechov in Finland. After a 2018 rebrand to Aave (Finnish for “ghost”), it launched its pool-based lending protocol in January 2020. Within a year it was the largest DeFi lending protocol by TVL, surpassing the incumbent Compound. A decade later, it’s still the biggest money market in crypto.

Aave’s innovations defined how DeFi lending works. Flash loans — uncollateralized loans that must be repaid in the same transaction — were a novel primitive that launched an entire category of arbitrage and liquidation bots. aTokens, receipts that automatically accrued interest, became a standard DeFi pattern. Credit delegation, rate switching, and eventually isolated markets in Aave v3 all pushed the state of the art forward. Other protocols copied nearly every Aave feature.

By 2024 Aave had over $20 billion in deposits across Ethereum, Arbitrum, Optimism, Base, Polygon, Avalanche, and several other chains. It had launched GHO, its native stablecoin, and had a governance token (AAVE) that appreciated meaningfully during bull markets. Stani Kulechov had become one of DeFi’s most respected founders, balancing protocol leadership with broader ecosystem work including the Lens Protocol social network.

Aave’s durability is the lesson. While dozens of lending competitors — MakerDAO, Compound, Morpho, Spark, Euler, Kamino, Radiant — each had their moment, Aave kept shipping, kept adding chains, kept adding features, and kept its risk frameworks conservative enough to avoid the catastrophic exploits that took down other lending protocols. In a space where most protocols peak quickly and decline, Aave is one of the few that’s stayed at the top for multiple cycles, largely through boring, relentless execution.

Morpho launched in 2022 with a clever observation: pool-based lending protocols like Aave and Compound were inefficient because borrower rates and lender rates had a big spread between them. Morpho built a matching layer that sat on top of Aave and Compound, matching borrowers and lenders peer-to-peer when possible, and falling back to the underlying pool when not. For matched users, both sides got better rates than the base pool offered.

The Morpho matching model was an incremental improvement on existing infrastructure. It wasn’t a replacement — it was a layer that made existing protocols more efficient. This positioning let Morpho scale fast without needing to bootstrap its own liquidity. By late 2023 Morpho had over $1 billion in assets matched through its system. The MORPHO token launched in 2024 and immediately became one of the most watched DeFi governance tokens of the cycle.

Morpho’s bigger play came with Morpho Blue in 2024 — a minimalist new lending primitive that let anyone create an isolated lending market with custom parameters. Each market was a single collateral-loan pair with configurable liquidation thresholds and oracle choices. Instead of Aave’s monolithic governance approving every asset, Morpho Blue let risk curators and individual users create markets on demand. It was a completely different architectural philosophy, and by 2025 it was capturing significant TVL from Aave for users who wanted more flexibility.

Morpho represents a shift in DeFi lending thinking: from heavyweight governance-controlled protocols to minimalist primitives with configurable risk. The core insight is that risk assessment, not liquidity bootstrapping, is the real hard problem — and that problem is better solved by specialized curators than by slow-moving DAOs. Whether Morpho’s architecture becomes the long-term winner or just one option among several, it has forced everyone in the lending category to rethink how the stack should be layered.
