Introduction
When exploring decentralised finance (DeFi), you may come across a metric called Total Value Locked (TVL).
You might see headlines such as “DeFi TVL is increasing” or “A protocol has reached $1 billion in TVL.” But what does this number actually tell you?
TVL is one of the commonly used metrics for understanding activity within DeFi protocols. It measures the value of crypto assets deposited or locked in a protocol’s smart contracts.
However, a high TVL does not automatically mean a project is safe, profitable, or successful.
In this lesson, let’s understand what DeFi TVL means, how it is calculated, why it matters, and what its limitations are.
What is TVL in DeFi?
TVL stands for Total Value Locked.
It represents the estimated market value of crypto assets deposited in a decentralised finance protocol or application.
These assets may be deposited for activities such as:
- Lending and borrowing
- Providing liquidity to decentralised exchanges
- Staking or participating in protocol-specific mechanisms
- Yield farming
- Supporting other DeFi services
For example, imagine a lending protocol has the following deposits:
| Asset | Deposited Quantity | Assumed Price | Total Value |
|---|---|---|---|
| ETH | 500 ETH | $2,000 | $1,000,000 |
| USDT | 500,000 USDT | $1 | $500,000 |
| DAI | 300,000 DAI | $1 | $300,000 |
| Total | $1,800,000 |
The protocol’s TVL would be approximately $1.8 million based on these assumed prices and the assets counted.
In simple terms, TVL helps show how much value users have deposited into a DeFi protocol.
How is DeFi TVL calculated?
The basic calculation is:
TVL = Total quantity of deposited assets × Their current market prices
The value of each supported asset is calculated and then added together.
For example:
- 100 ETH × $2,000 = $200,000
- 200,000 USDT × $1 = $200,000
- 50 BTC × $40,000 = $2,000,000
The estimated TVL would be $2.4 million.
These prices are only illustrative.
In practice, TVL calculations depend on the protocol’s accounting methodology, supported assets, price sources, and which deposits are included.
Why is TVL important in DeFi?
TVL gives users and analysts a way to understand the scale of activity within a decentralised finance protocol.
Here are four reasons why people monitor it.
1. Understanding Protocol Adoption
A growing TVL may indicate that more assets are being deposited into a protocol.
For example, if a lending platform’s TVL increases over several months, it may suggest that more users are supplying assets to its markets.
However, TVL alone cannot confirm how many individual users are participating.
2. Comparing DeFi Protocols
TVL can help users compare the amount of value held across different DeFi platforms.
For example, you could compare two lending protocols to see which one holds more deposited assets.
However, a larger TVL does not automatically mean that one protocol offers better security, technology, or services.
3. Understanding Liquidity Availability
TVL can provide information about the amount of assets deposited in certain DeFi applications.
For example, a decentralised exchange may use TVL to show the value of assets deposited in its liquidity pools.
However, TVL is not the same as immediately available liquidity. Some deposited assets may be difficult to withdraw or may not be available at the price users expect.
4. Tracking Changes in DeFi Activity
Changes in TVL can help analysts observe how activity within DeFi protocols changes over time.
An increase may reflect new deposits, rising asset prices, or both.
Similarly, a decrease may result from withdrawals, falling asset prices, or changes in the assets included in the calculation.
Therefore, understanding why TVL changes is just as important as watching the number itself.
What does Rising or Falling TVL mean?
TVL movements can offer useful clues, but they should not be interpreted without context.
Rising TVL
An increase in TVL may happen because:
- Users deposit more assets.
- Existing users increase their deposits.
- The market prices of deposited assets rise.
- A protocol attracts liquidity through incentives.
Rising TVL may indicate growing activity, but it does not guarantee that a protocol is becoming safer or more successful.
Falling TVL
A decrease in TVL may happen because:
- Users withdraw their assets.
- Deposits move to competing protocols.
- The market prices of deposited assets fall.
- Liquidity incentives are reduced.
- A protocol experiences security or operational concerns.
A falling figure does not always mean users have lost confidence. Market-wide price declines can also reduce the reported value of deposits.
The Limitations of TVL: What beginners should know
TVL is useful, but it does not tell the complete story of a DeFi protocol.
Here are some important limitations.
1. TVL Changes With Cryptocurrency Prices
TVL is usually measured in a common currency, such as US dollars.
Therefore, changes in asset prices can affect the reported value even when the number of deposited tokens remains unchanged.
For example, if a protocol holds 1,000 ETH and ETH’s price increases, its TVL may rise without receiving any additional deposits.
2. High TVL Does Not Guarantee Security
A protocol may have billions of dollars in deposits but still contain smart contract vulnerabilities.
Security depends on several factors, including code quality, audits, access controls, and the protocol’s overall design.
A large TVL should never be treated as proof that funds are safe.
3. TVL Does Not Always Represent Unique Deposits
The same underlying assets can sometimes be counted across multiple DeFi protocols.
For example, a user may deposit ETH into one protocol, receive a token representing that deposit, and use that token in another DeFi application.
Depending on the tracking methodology, this can create double counting.
As a result, adding together the TVL figures of multiple protocols may overstate the amount of unique capital in DeFi.
4. TVL Does Not Measure Profitability
A protocol with high TVL is not necessarily generating strong revenue.
TVL measures the estimated value of deposited assets, not how much money the protocol earns.
To understand financial performance, users should examine other metrics, such as fees, revenue, expenses, and token incentives.
5. Incentives Can Temporarily Increase TVL
Some DeFi protocols offer rewards to encourage users to deposit assets.
These incentives can attract temporary liquidity.
When rewards decrease or end, users may withdraw their deposits.
Therefore, a sudden increase in TVL should be examined alongside the protocol’s incentive structure.
TVL vs Market Capitalisation: What’s the difference?
Beginners sometimes confuse TVL with market capitalisation, but they measure different things.
| Feature | TVL | Market Capitalisation |
|---|---|---|
| Full form | Total Value Locked | Market Capitalisation |
| Measures | Value of assets deposited in a DeFi protocol | Market value of a cryptocurrency |
| Basic calculation | Deposited assets × their prices | Token price × circulating supply |
| Main purpose | Understand deposited value and protocol activity | Understand the relative market value of a cryptocurrency |
| Common use | Comparing DeFi protocols | Comparing cryptocurrencies |
For example, a DeFi protocol may have $500 million in TVL while its native token has a market capitalisation of $100 million.
These figures measure different things and should not be compared as if they represent the same type of value.
How should beginners use TVL when researching a DeFi project?
TVL can be a useful starting point when researching a DeFi platform.
However, do not rely on it alone.
Consider these five checks:
1. Check the TVL trend: Look at how the figure has changed over weeks or months rather than focusing on one day.
2. Understand the protocol’s purpose: A lending platform, decentralised exchange, and liquid staking protocol have different functions. Compare similar platforms where possible.
3. Examine the assets deposited: Check which cryptocurrencies contribute most to the reported value.
4. Research security: Review available audits, security disclosures, known vulnerabilities, and the protocol’s risk controls.
5. Check other performance metrics: Consider fees, revenue, active users, liquidity, and incentive programmes for a broader understanding.
Remember, TVL is one research metric, not a complete measure of a project’s quality.
Frequently Asked Questions (FAQs)
1. What does TVL stand for in DeFi?
TVL stands for Total Value Locked. It represents the estimated market value of crypto assets deposited in a decentralised finance protocol.
2. Is higher TVL always better?
No. Higher TVL indicates that a protocol holds more deposited value, but it does not guarantee security, profitability, or better performance.
3. Can TVL decrease without users withdrawing their assets?
Yes. If the market prices of deposited cryptocurrencies fall, the reported TVL can decrease even when users do not withdraw their tokens.
4. What is the difference between TVL and liquidity?
TVL measures the value of deposited assets. Liquidity refers to how easily assets can be traded, withdrawn, or converted without significantly affecting their price. A high TVL does not automatically mean high usable liquidity.
5. Where can I check DeFi TVL?
You can explore DeFi analytics platforms such as DefiLlama and individual protocol dashboards. Always check their methodology and the date of the reported figures.
6. Does TVL measure the number of DeFi users?
No. TVL measures deposited value, not unique users. A protocol can have high TVL with a relatively small number of large depositors.
