What is tvl?

The short answer

TVL adds up the value deposited in DeFi, in one protocol or across a whole ecosystem. It is a stock measure, a snapshot of what sits in contracts. It is not a flow of earnings. Data providers compute it from on-chain state and price feeds. That makes it a database figure, and every honest use of it carries a date.

The definition, sourced and dated

The common wording is the glossary entry read 11 September 2026. This site carries it as a competitor-claimed definition tier, medium confidence. Total Value Locked is a metric in crypto. It represents the total value of digital assets currently deposited or locked in a specific DeFi protocol, platform, or across an entire blockchain ecosystem ^[1]. Definitional content of this kind is uncontroversial. The number, wherever it appears, is the part that needs discipline.

The measurement side has a stated methodology. DefiLlama’s API series underlies the figure this site quotes, read 11 September 2026. The series holds 3,272 daily points, and its last point falls on that date ^[2]. For a third-party aggregate like TVL, the primary of record is the data provider, labeled database-reported. That is stated honestly rather than forced into a protocol-doc framing that does not exist for this metric.

The mechanism

TVL is computed, not reported by anyone in charge. The provider enumerates the contracts of each protocol. It reads the token balances those contracts hold on each chain, prices every token, and sums. The series then moves for three different reasons. Deposits move it. Prices move it, since the same holdings are repriced daily. And methodology moves it, when a contract list is revised or a pricing source changes.

That triple sensitivity is why this site’s usage rules exist. A TVL figure is quoted with its provider and its date. Never without. It is never blended across providers. And protocol-level figures are presented as scale examples, never as a ranking. The DeFi pages apply the same rules at full length. Their method notes cover what the aggregate counts.

The neighboring slice deserves its own line. L2Beat computes value secured for layer 2 networks. It is a related but distinct aggregate, and this site quotes it with its date. The layer 2 term carries that family.

Two dated examples

The headline figure. Total DeFi TVL across chains was 88.71 billion dollars at 11 September 2026. The source is the DefiLlama pull of that date ^[2]. A second same-day pull quoted on this site’s DeFi pages read 88.70 billion dollars. The two pulls differ by intraday drift. They are never averaged into one number. Each keeps its own date and its own capture.

The layer 2 slice. Ethereum layer 2 value secured was 42.86 billion dollars, up 27.2 percent over one year, in the L2Beat render of 11 September 2026. The same render counted 22 rollups, 6 validiums and optimiums, and 76 others ^[3]. For stablecoin-side scale, banked chain totals read 147.0 billion dollars on Ethereum and 93.75 billion on Tron. The date is 9 September 2026. These are different instruments, protocol deposits, rollup security, and stablecoin circulation. This site never sums them.

What TVL is not

Three refusals keep the term honest. TVL is not a safety measure. A large deposit base says nothing about a protocol’s risk profile. TVL is not a yield, despite the two being discussed together. Deposits can earn nothing or lose value. And TVL is not comparable across providers without method notes. The contract lists and pricing sources differ. The DeFi page’s methodology section carries the full version of these rules.

What is TVL?

A metric for the total value of digital assets deposited or locked in a specific DeFi protocol, platform, or across a whole blockchain ecosystem. Data providers compute it from on-chain balances and prices. It moves with deposits, prices, and methodology, so every use carries its provider and date.

What is an L2, or layer 2?

A network built on top of Ethereum that inherits its settlement. The security-relevant test is whether the network stores its data on the Ethereum main network. L2Beat’s value-secured aggregate is the TVL-adjacent slice for that family, quoted with its date. The layer 2 term page carries the full definition.

What is DeFi?

Short for decentralized finance, the application layer TVL was built to measure. Lending markets, exchanges, and issuance protocols hold deposits in contracts. TVL aggregates the value of those deposits across the ecosystem. The DeFi page covers the layer itself, with the same dating rules this page applies to its figures.

Where this term sits

The cryptocurrency hub frames the cluster. The sibling terms layer 2 and RWA mark the neighboring aggregates, rollup security and tokenized claims. Every figure above carries its source and date.
