Biggest DeFi Protocols by TVL and What Each One Does

These are the nine largest DeFi protocols by total value locked, ranked largest first, on a day when DefiLlama counted $93.9 billion across the whole of DeFi (September 21, 2026). Lido alone held $25.998 billion of it. Where DefiLlama's own reading for a protocol was not available, the order follows Thrive's reproduction of the same table dated September 25, and every figure carries its date, because the ranking moves from week to week.

The conclusion is less flattering than the headline sum. Most of this list is staked ether in one wrapper or another, or loans secured by it, and some of the same coins are counted more than once. Binance's staked ETH product, fifth at $10.0 billion, is left out because it belongs to a centralized exchange, not a protocol. Uniswap, the best-known exchange in DeFi, does not make the top ten at all.

First, at $20 billion according to DefiLlama. Lido is a liquid staking protocol: it stakes ETH and returns stETH, which earns staking rewards and can still be traded or used elsewhere. The yield is Ethereum's own staking reward, put at roughly 4% by Thrive on September 25, and Token Metrics estimates Lido's annualized protocol revenue at $53.4 million.

The risk is concentration. Estimates of Lido's share of all staked ETH run from 24.2% (Dwellir) to more than 30% (Thrive), and Token Metrics names validator concentration as its main concern. One market report notes that Lido V3 positions stETH as the layer underneath restaking rather than as a rival to it. That is how the same ether turns up again further down this list. The sources used here do not say what the LDO token governs.

Second, at $14.7 billion, the largest lending protocol, deployed on more than 20 chains. Depositors earn what borrowers pay. Estimates of what the protocol keeps range from $73.4 million a year (Token Metrics) to more than $500 million (Thrive), a spread that says more about the estimators than about Aave. Dwellir reports a fee switch linking staker rewards to protocol revenue.

Much of Aave's governance never reaches a token vote. LlamaRisk, the Risk Steward, adjusts caps and rates through an automated process and posted changes on seven separate dates in September 2026. On September 22 it doubled the wstETH borrow cap on V3 Core from 14,000 to 28,000, after utilization reached 99.8% and the median health factor among top borrowers stood at 1.11.

The problem in September was GHO, Aave's own stablecoin, which traded as much as 13.6 basis points below $1.00 over the 30 days to mid-September. Redemptions cut the Ethereum USDT stability module's reserves from 40.8 million to 18.6 million. TokenLogic's September 15 proposal proposed raising the Horizon borrow rate from 3.00% to 3.25%, on the reasoning that "every loop opened at that rate is GHO minted at 3.00% and sold into the market."

Third on DefiLlama's full protocol list, at $14.13 billion in late September. SSV Network is Ethereum-only staking pool infrastructure. DefiLlama's top-protocols view nonetheless places EigenLayer third, at $7.6 billion, with Morpho fourth, so the order at this rung depends on which DefiLlama view is being read.

The sources used here say nothing about SSV Network's yield, its governance or its incident record. It is on the list for its size alone, and size alone describes very little. A depositor needs those other three answers from SSV Network's own documentation before any of its $14 billion should be taken as reassurance.

Fourth, at $7.4 billion according to DefiLlama, spread across more than 40 chains. PANews describes it as the leading lender on Base. Token Metrics records $0 in annualized protocol revenue and describes Morpho as working "more like lending rails than a classic fee-hungry protocol". The practical meaning is that Morpho supplies the market structure and lenders' returns come from borrowers, with little taken in between. The sources used here do not set out what MORPHO holders control, and they record no incident.

Sixth at $7.0 billion per Thrive on September 25, and now at $7.6 billion per DefiLlama. A report drawing on DefiLlama data for September 20, which counted restaked assets in full, put the same protocol at $18.37 billion. That gap is the double count in miniature.

The mechanism, as Coin Bureau describes it, works in stages. Users commit ETH or liquid staking tokens and delegate them to operators. The operators then choose Actively Validated Services, such as the data availability layer EigenDA, which pay rewards and set the conditions under which stake is slashed. Slashing went live on April 17, 2025. Thrive quotes yields of 5 to 15%, while Token Metrics records the protocol's own revenue as $0. The EIGEN token exists to settle "intersubjective" faults that cannot be proven purely on-chain. Coin Bureau lists the risks as slashing, operator quality, contagion if a liquid restaking token loses its peg, and phishing through the several wallet approvals restaking requires. Dwellir puts EigenLayer's share of restaking above 85%.

Seventh, with Sky at $6 billion. Sky issues stablecoins against collateral, and CoinGabbar credits it with $174.9 million in annualized revenue, the highest among the protocols it ranked.

Its governance is the most legible on this list. The September 24 executive vote had 4,600,799,152 SKY in support in mid-September, before it had passed. It bundles the activation of cBEAM for Osero, a resolution on the real-world asset RWA009-A, and the whitelisting of Prime Agent spells for Spark, Grove and Osero. An executive of this type waits out a 48-hour delay once passed and expires if it has not passed within 30 days, and vault changes execute only between 14:00 and 21:00 UTC on weekdays. An earlier change cut the ALLOCATOR-PRYSM-A debt ceiling from 10 million to 5 million USDS, and it was approved by a Core Council Risk Advisor rather than a full poll.

Eighth on this list. Spark is one of the sub-protocols whose Prime Agent proxy spells were slated for whitelisting in Sky's September 24 executive. SparkLend's rules are therefore set partly through Sky's executive process, and anyone assessing SparkLend is also assessing Sky's governance. The sources used here give no separate yield figures or incident history.

Ninth, at $5.2 billion as liquid staking. The September 20 report puts ether.fi at $11.29 billion in total, of which $10.08 billion is liquid restaking, meaning stake that has been wrapped and then restaked. The risk Coin Bureau attaches to that structure is a liquid restaking token losing its peg and taking positions built on top of it down with it. Tenth place, Ethena's USDe at $4.9 billion, shows the same pattern of borrowing at the edge. On Aave's Plasma market, its top five suppliers held 94.8% of reserves, and six of the top eight carried debt with health factors between 1.01 and 1.05.

Taken together, the top of DeFi is one large holding of ether, measured from several angles: staked in one protocol, restaked in another, and posted as collateral in a third. Lending and staking fill most of the slots. The DEX category, which PANews reports earns $5.9 million a day in fees, holds only about $18 billion in total.

The strongest objection is that TVL is too unreliable to rank anything, and it deserves a full concession. The September 20 report gave Lido $33.92 billion and Aave $33.66 billion, which together come to more than 70% of a $92.04 billion total, a result only possible if the same assets are counted twice. Dwellir, using a wider methodology, puts total DeFi at $130 to $149 billion. The figures are soft. The ranking survives that, because it still shows where deposits sit and whose risk settings govern them, and the double counting is itself the finding. For how lending and staking protocols fit together in general, the wider guide covers the mechanics. The useful question before depositing in any of these nine is not how large the protocol is, but how many of the other eight sit underneath the asset being deposited.
