Some would like to describe 2025 as a very unusual year in the world of cryptocurrencies. In 2025, capital piled into DeFi, but user attention only stayed concentrated on a smaller set of ecosystems. Cointelegraph, citing DappRadar reported that DeFi TVL hit a record $237B in Q3 2025, even as daily unique active wallets averaged 18.7M which is down 22.4% quarter over quarter.

This gap between TVL and active wallets showed that there is money in the system but fewer people are actively using apps. This is a matter of concern when you zoom into individual Layer s. While some chains are still alive producing blocks, explorers working and transfers happening, their economic traffic is very thin. They have low trading volumes, low fee generations and shallow liquidity. Many Layer 1s still benefit from what CoinDesk has termed infrastructure premium. That is having a high valuation based on technological promise rather than actual usage. Let's look at data backed critiques of blockchains that, despite past hype, have become digital ghost towns of 2025.

Defining a Zombie chain

A zombie chain or a ghost chain is a blockchain that is technically operational but suffers from severe lack of user adoption and developer engagement. In normal terms such a blockchain would be like a city with very nice roads and amenities but lacking cars, shops and people. Such blockchains have clear characteristics that include negligible transaction volumes, stagnant development, razor thin liquidity on exchanges and a declining number of active applications.

Now, zombie chains are different from scam chains. They simply refer to blockchains that are in a state of low economic vitality. This means that their on-chain activity does not justify the network’s valuation. To identify such chains, I analysed data from DeFiLlama as of December 16, 2025, focusing on the following metrics.

• DeFi TVL which is the total capital deposited in the chain’s finance apps.
• 24 hr chain fees which directly measure the demand for block space.
• 24 hr DEX volume which is the amount of money being traded, indicating active markets.
• Stablecoin market cap which is the amount of spendable cash in the ecosystem.

Using these metrics, we came up with a list of the top 5 zombie or ghost chains in the crypto markets.

Top zombie chains in 2025

Harmony (ONE)

Harmony has a market cap of over $53 million and it is far from being worthless. However, a look at its on-chain vitals tells a different story altogether. Its DeFi ecosystem holds a meager $549K in TVL and in the last 24 hrs, the entire network generated  just $3 in fees from about $1000 in DEX volume. As much as you may like this zombie chain, these numbers suggest an extremely small user base. And in such a scenario, even minor trades could face significant price slippage due to lack of liquidity.

If  such a chain is not a zombie blockchain I don’t know what else isn’t!

NEO (NEO)

This chain was often called the Ethereum of China in some  spaces in its heyday. Even today NEO maintains a recognizable brand and a market cap exceeding $265 million. However, with all this market cap, its DeFi footprint is vanishingly small. NEO only has $5.4 million in TVL and a paltry some of $170 in daily fees, this just shows very little economic energy. As if this is not enough, its stablecoin market is almost entirely reliant on a single  asset (USDT). This signals a fragile and shallow ecosystem. If this keeps going on, this zombie chain will actually cease to exist!

IOTA (IOTA)

IOTA is one of the leading zombie chains in 2025, despite  commanding a significant valuation of over $386 million. This blockchain is largely built on its unique Tangle technology narrative. However, when it comes to on-chain capital, the story changes and the glitters turn to ash. Its DeFi ecosystem has attracted just $9.87 million in TVL. This is a classic example of a project where the technological hype and market valuation have become disconnected from real world financial usage. 

Yes, the tech is good, but no one wants it!

Tezos (XTZ)

Tezos has a market cap of nearly half a billion dollars and a respectable $54.3 million in stablecoins on its network. However, its DEXs processed only a miniscule $377 in volume in the last 24 hours. The network did generate over $1000 in fees, but this activity appears heavily subsidised with $108k in token incentives distributed during the same period. This suggests that much of the existing  activity may be artificially propped up rather than being organic. 

Much like vote buying to me, the Tezos team needs to do something fast or their zombie will disappear!

Algorand (ALGO)

When you look at the massive over $1 billion, Algorand market cap, you would think it's a big giant! Algorand is the most highly valued chain on the list. It does show some signs of life with over 29000 active addresses, which means you may think that it's not yet fully zombified. However, its DeFi footprint of $45.46 million in TVL looks good on paper but is very misaligned with the billion-dollar valuation. In the past 24 hours the network generated only $19 in fees from $1.88 million in DEX volume. This is a crucial reminder that  metrics like  active addresses can be very misleading. This is because they may be influenced by airdrops, incentives or automated bot activity.

How you can avoid the zombies

As an investor or builder, how do you spot a potential ghost town before it's deserted? Look for a confluence of positive signals, not just one. A healthy chain must have a deep TVL and a robust stablecoin market, indicating capital is present. It must also generate significant fees from high DEX volume, proving that people are actively using it. Finally, the success of an active chain must not be reliant on a single "lonely" dApp. In addition its developer community must consistently ship new updates and products. Anything that does not tick all the boxes is probably a zombie.

Final thoughts and conclusion

Ultimately, a blockchain can be fast, cheap and have brilliant technology but if no one shows up it's just empty code. In 2025, it's clearer than ever that traction is a product, not a promise. I have seen many chains entice users with airdrops and then ditch them at TGE. I have news for the founders, zombification will find you one way or the other. Just be prepared!
