The greater part of DeFi capital sits in three categories: lending, decentralised exchanges, and liquid staking. Evaluating any onchain position depends on understanding what each category does, how the capital within it is measured, and why some categories come to be led by a single protocol while others remain divided among many.

The aim of this article is descriptive: it defines the three categories and the role each plays, it sets out the two measures used to read concentration, and it explains the structural forces that cause capital to cluster in some places and spread in others, all while staying neutral on which protocols are the right ones to use. 

What it offers is the map an allocator consults before deciding where to stand.

The Three Categories

Each of the three plays a distinct role, and those roles account for much of how each behaves. 

Lending forms the credit and leverage base layer, where depositors supply capital to a market and borrowers draw loans against collateral at a rate set by how much of the available capital is in use. Holding roughly half of all DeFi capital, lending sits at the base of the stack because the rest of the system runs on the credit it provides, and demand to borrow persists across conditions since leverage, hedging, working capital, and yield strategies all depend on it.

Decentralised exchanges form the execution and liquidity layer, allowing one asset to be swapped for another against a pool of capital supplied by liquidity providers in place of a traditional order book. The capital in the pool serves as the inventory that makes swaps possible, while the activity that matters is the trading itself, measured in volume, and the revenue it produces, measured in fees. The locked capital enables the product without being the product itself.

Liquid staking forms the yield-bearing collateral base. A holder stakes an asset to help secure a proof-of-stake network and earns the network's staking reward, receiving in return a token that represents the staked position along with its accruing reward. That token stays liquid and usable across the rest of DeFi while the original asset remains staked, which lets liquid staking convert capital that would otherwise sit idle into collateral that works in two places at once.

How These Categories Connect

The three categories operate as a single system rather than as separate markets. 

  • Liquid staking produces collateral that lending markets accept and that exchanges trade. 

  • Lending supplies the leverage that drives much of the trading volume on exchanges.

  • Exchanges price the assets that lending markets rely on to value collateral and to determine when a loan must be liquidated. 

Capital and risk move among the three continuously, which is why concentration in one category does not stay confined to it, and why a dominant staking token is at the same time a lending collateral and an exchange pair while a dominant lender is also the source of leverage for traders across venues. 

Any honest map has to show these connections, because risk travels along them.

Two Ways to Measure Concentration

Two measures carry most of the weight in reading the data, and keeping them apart is the first step toward reading it well. 

Top-five dominance is the share of a category's capital held by its five largest protocols, and it indicates how heavily a category leans on its leaders, with a reading near three quarters describing a category that depends on a few names and a reading closer to sixty percent describing one that depends on them less. Single-name share is the portion held by the single largest protocol, and it indicates how much rests on one venue.

The distance between the two describes the shape of a category's leadership. A category whose leader holds close to half, with the next four dividing the remainder of the top five, is led by one name, while a category whose top five sit closer together in size is led by a group. Lido at 47.47% illustrates the first shape, and the exchange top five, where no single name reaches a quarter, illustrates the second.

Size and Concentration Are Separate Questions

Dominance describes a category from the inside, while category share describes it from the outside as a portion of all DeFi capital, and the two vary independently, so a category can be large or small and concentrated or fragmented in any combination.

Category

Role in the stack

Category size

Internal concentration

Lending

Credit and leverage base

Largest, about half

High, about 73%

Liquid staking

Yield-bearing collateral

Smaller

Highest, about 76%

Exchange

Execution and liquidity

Smallest of the three

Lowest, about 62%

The combination matters because the same risk carries different consequences depending on where a category falls. A failure in a small and fragmented category stays largely contained, whereas a failure in a large and concentrated one does not, which places lending in the most consequential position of all, since it is at once the largest category and one of the most concentrated, putting more of the system's weight on its leaders than anywhere else in the stack.

Why Some Categories Concentrate and Others Fragment

Concentration follows the kind of advantage a category rewards, and two kinds appear plainly in the data, pulling in opposite directions. 

Where the advantage is liquidity depth, capital concentrates, as it does in lending and liquid staking. Deeper lending markets absorb large positions with less disruption, carry more thoroughly tested risk parameters, and attract the integrations that bring further deposits, so each quality makes the deepest market more attractive and therefore deeper still. 

In liquid staking, the same loop runs through the acceptance of the staking token, because the more venues that accept a token as collateral and trade against it, the more useful it becomes, and the more capital flows to the provider whose token is most widely accepted. Depth of this kind compounds into a lead that is difficult to challenge, which is why both categories show a single clear leader and a high top-five share.

Where the advantage is chain-local execution, capital fragments, as it does among decentralised exchanges. An exchange's liquidity lives on the chain it runs on, and liquidity on one chain cannot fill an order on another, so each major chain develops its own dominant exchange serving the assets and users native to it. No single exchange leads everywhere, because leadership is won chain by chain, which is the structural reason exchange concentration sits below lending and staking. The category remains every bit as competitive, divided into separate contests in place of a single one.

Tvl Means Different Things in Different Categories

Total value locked is the standard gauge of size in DeFi, yet it does not carry the same meaning in every category, and treating it as though it did is among the most common errors in reading the data.

In lending and liquid staking, locked capital is the product itself, since the deposits are the thing being supplied and used, so when total value locked rises or falls in these categories, their core activity rises or falls with it, and the figure measures their size fairly.

In decentralised exchanges, locked capital serves as collateral for the product instead of being the product, because the product per se is trading and the revenue is fees. An exchange can watch its locked capital decline while its volume and fee income hold, since the two are driven by different forces, with locked capital following the value of the assets in the pools and volume following market activity. Reading exchange health from locked capital therefore measures the inventory in place of the business and gives a misleading impression of both, which is what it means to choose the right denominator for each category.

The Vocabulary in Brief

A small set of terms makes the rest of this analysis precise. 

  • Top-five dominance is the share held by a category's five largest protocols.

  • Single-name share is the share held by its single largest, and category share is a category's portion of total DeFi capital. 

  • Chain-local fragmentation describes the way a category divides across chains because liquidity is bound to the chain it sits on.

  • Denominator refers to the choice of the right measure for each category, which is locked capital for some and volume or fees for others.

With the categories, the measures, and the forces behind them in view, the structure of onchain capital becomes legible. Lending sits at the base and concentrates around depth, liquid staking concentrates around how widely its token is accepted, and exchanges fragment because liquidity is bound to the chain beneath them. 

Reading any individual protocol against that backdrop, and against the right denominator for its category, is the difference between knowing a position's headline number and understanding what the position actually carries.
