Locking in liquidity does not mean token security

The truth about liquidity lock-in: It's no longer a security signal

Every relevant guide tells you the same thing: locking in liquidity means that teams cannot carry out carpe-pulling fraud on you, so tokens are safer. This statement does hold true when the only way out is to drain the pool. But on modern launch pads, lockdown has become the revenue engine of scams, and the checkmark you are looking for is exactly what is paid to the attacker.

Summary

Locking in liquidity means that tokens representing transaction pool assets are stored in a time-locked contract that cannot be extracted by the creator, preventing the classic "carpet-pulling" fraud-where a team drains the pool and disappears.

Almost all explanations regard this as a security signal, and it does in the narrow sense: the specific attack it prevents is real and was at one point the main way for memin buyers to lose money.

Modern launch pads combine lock-in liquidity with recoverable creator fees, so pools that cannot be drained will still pay creators a portion of each transaction indefinitely. This combination transforms one-time theft into a permanent revenue stream, which means an attacker has no reason to "pull the carpet" because it is more profitable not to pull the carpet than to pull the carpet.

Locking in liquidity also does not explain supply concentration, contract authority, team identity, or whether anyone will trade the token next week.

The check mark

On the token screening tool, the launch pad interface, and on every security list compiled for memein traders, there is a check box: Liquidity locked. Finding it is seen as one of the basic steps before buying an anonymous token, and the logic behind this suggestion is reasonable to some extent. Liquidity lock-ins do prevent one of the most damaging attacks in decentralized finance-carpet pulling, in which token creators remove assets that support trading pools, leaving holders with only what they cannot sell. Various guidelines agree that verification lock-in is not an option, but a must; another guide says it can assure investors that projects are safe and available to participate; and another guide says it gives investors a sense of security. All of this describes true protection, but none is complete, and this incompleteness has become costly. Because, on the launch pad where most new tokens are born today, the same lock that prevents creators from draining the pool also ensures that creators receive a share of each transaction that is permanent-changing the meaning of that checkmark.

What does liquidity locking actually do?

Let's start with the mechanism, because this protection is real, and an accurate understanding of it will let you see where the vulnerability lies.

When a token is launched on a decentralized exchange, someone must provide a pool for users to trade. This means depositing the new token into a pool contract along with something of value (usually a stablecoin or a native asset of the chain). In exchange, depositors receive liquidity provider tokens, which are a claim for the deposit. People holding provider tokens can redeem them and withdraw the contents of the pool.

This request for credentials is the entire loophole. The creator who holds it can wait for the buyer to arrive, watch as the pool is filled with real money, and then redeem the voucher, withdraw everything of value, leaving nothing behind the token. The price will drop to zero because there is nothing to sell. This is "carpet pulling" fraud, which has accounted for a huge share of memin losses over the years.

Liquidity locking is the sending of provider tokens into a separate time-locked contract rather than leaving them in the creator's wallet. The lockdown service will hold them for a specified period of time, publish the lockdown information on the chain for anyone to verify, and refuse to release these tokens before expiration. Creators cannot redeem what they no longer hold. The classic exit method is mechanically blocked.

There are two easily misunderstood clarifications. First, the locked pool is still traded normally; the lock restricts the extraction of pool content, not the sale and purchase of the pool. Second, liquidity lock-in is different from token lock-in, which limits the team's own supply through an unlocking program. A project can do only one item and ignore the other, and the checkbox you see usually only covers the former.

What's right about the guide

Before criticizing, give due recognition-because it would be wrong to completely deny locking.

The evidence of unlocked pools is indeed worrying. An analysis of a thousand memecoins on a major chain found that more than 90% had no locked liquidity, making them structurally vulnerable to such attacks. Industry estimates show that the loss of memo fraud in a single year is as high as hundreds of millions of dollars, of which draining the pool is the main means. Using this as a benchmark, a lock-in liquidity project does eliminate a real and common failure mode, and the difference between locked and unlocked pools is not superficial.

Locking also has a certain signaling function, which has its value. A team that is willing to give up the ability to withdraw a pool is a team that accepts constraints, and the constraints voluntarily accept are often associated with the intention to survive even when prices fall. This correlation is weak, but the weak correlation still carries information.

Therefore, the guidelines are not wrong about locking. They are wrong in locking in on what they imply, and the gap between the two is where the current generation of scams operates.

Inversion

The following are changes that have not been absorbed in the safety literature.

The launch pad of the Pump.fun pedigree-its underlying mechanism-automates token creation and structurally solves the carpet-pulling problem: When a token graduates from its launch curve and enters the trading pool, the platform permanently locks in liquidity and places it into a contract that no one can drain. This is a real improvement and the foundation of these platforms 'self-proclaimed "tensile carpet."

These platforms also pay creator fees. A locked pool will still incur transaction fees per transaction, which can be collected at the address where the token was created. This arrangement makes sense on the surface: it rewards builders whose tokens have real trading volume and gives creators a reason to continue supporting the project rather than dumping it out.

Now combine these two properties and follow the excitation. A creator who cannot drain the pool loses a source of income. A creator who charges a fee on every transaction gets another income, and the second income doesn't require tokens to succeed, it just needs to be traded. Panic selling generates volume as good as enthusiastic buying. The transaction volume generated by holders trying to exit coins they now consider worthless is just as good as the former.

Lock removal is the exit method. What it doesn't remove is the extraction behavior, and it transforms the extraction from an event to a subscription mode.

This is not a theoretical concern. When an attacker hacked into the social account of a well-known executive and launched tokens on a platform whose design eroded credibility, the operation was based on this design: liquidity was permanently locked, transaction fees were repeatedly collected in the first few hours, and no carpet was pulled throughout the entire process-because pulling the carpet would interrupt the cash flow that an attacker had every reason to continue to collect. The token cannot be drained, but it does not need to be drained. For reports surrounding this argument, the $VLAD case documents the complete extraction process.

Why that checkmark is now misleading

The actual harm is not that lockouts are useless, but that they play a supporting role in a mental model that no longer describes current risks.

A trader executing a standard list sees "Liquidity locked", checks the box, and then considers a type of hazard as resolved. This is correct. But the same traders would typically view this checkmark as a broader legitimacy signal-because every guide states it this way-and on a platform where lock-in is automatic and common, it does not carry any information about the project itself at all. When every token on a platform locks liquidity by default, the existence of the lock cannot distinguish anything. It is not a filter, but a floor.

What's worse, it subverts the usual scam detection heuristic. Historically, a suspicious token seems suspicious: no lockdown, anonymous team, contracts with casting capabilities, and supplies concentrated in a few wallets. And a launch pad token created to collect fees looks clean on the most-cited metric because the platform automatically makes it clean. The design that makes attacks profitable is precisely the design that makes attacks pass inspection.

Things locking can't tell you

There are five things that are completely outside the coverage of liquidity locking, and each of them has caused more damage in recent cycles than draining the pool.

Supply concentration. Locks cover the pool, not tokens held by insiders. Creators who hold large supplies can continue to sell to the pool, which is a slower carpet pulling that produces the same results for the holder. Please check the distribution of top holders separately.

Contract permissions. Coining functions, transfer restrictions, blacklists, and modifiable fee parameters are all present in the token contract, not in the pool. If a locked pool is attached to a contract that the owner can forge indefinitely, it has no practical protection.

Lock in terms and terms. Lock will expire. A token advertised as a long-term project is locked for only thirty days, which tells you when the risk will return. Please read the expiration time and read whether the locker allows early withdrawals under any conditions.

Creator fee arrangements. This is the theme of this guide. If the platform pays a fee to the token creator, understand this: A marked, publicly known scam continues to earn revenue for its operator every time someone trades it-including when you sell it.

Whether anyone will trade it tomorrow. The most common way to lose money on new tokens is not pulling carpet at all. Instead, buy a pool that becomes illiquid within a few days, leaving a position that can only be exited at a catastrophic price. No locking can solve this problem.

Blind spots in screening tools

Most traders never read locked contracts. They read a screening tool that condenses all of the above into icons. Understanding what screening tools can and cannot see is more practical than understanding the underlying mechanisms.

Screening tools are good at observing what is verifiable and easy to check along the chain: whether the liquidity provider token is in a known lock-in contract, when the lock-up expires, whether ownership of the token contract has been waived, whether a casting function exists, how supply is distributed among the largest holders, and how much liquidity is behind the pool. These are facts with clear answers, and the screening tool to accurately report these facts has done its job.

What screening tools cannot see are intentions and arrangements. It cannot tell you whether the creator is still collecting transaction fees because it is a normal contract call that is indistinguishable from other calls in the overview view. It cannot tell you whether the wallet in which the tokens are deployed belongs to someone who has done the same operation eleven times before, unless the addresses are associated and tagged. It cannot tell you that the name and image of the token were stolen from a stolen account an hour ago because the fact exists completely offline.

This gap is important because the current generation's extraction behavior is based on this gap. Everything the screening tool checks appears clean because the launch pad makes it clean by default; and everything that identifies the problem-transaction history, social background, fee collection patterns-has no icon to summarize. A trader who treats a clean screening tool as safe for everything, effectively outsources judgment to tasks for which the tool was never designed.

The actual adjustment is small. Use screening tools for what it is good at measuring-namely contract authority and supply distribution-and treat liquidity lock icons as background information rather than final conclusions. Then spend thirty seconds looking at what it can't see: where the token comes from, who is promoting it, and whether anyone has marked the contract.

How to correctly evaluate a token

Replace the single check box with a short sequence. None of this takes a few minutes, and it handles design changes that break old heuristics.

Look at the holder distribution first, not lockdown. If a few wallets hold most of the supply, lock-in is irrelevant because you don't need to go through the pool to exit.

Check the permissions of the contract. The screening tool flags casting rights, ownership status, and transfer restrictions. A contract that has not relinquished ownership and has active casting functions has greater risk than an unlocked pool.

Suppose a lock exists and ask what it costs you. For launch pad tokens, lockdown is standard. The relevant question is not whether liquidity is locked up, but who is collecting transaction fees and whether the creators are still collecting them.

Tokens that have been marked are considered permanent. If a browser flags a contract as a suspected scam, trading it is not just risking your funds; on a paid platform, it is paying the operator. No form of participation is neutral.

Assess the risk of insufficient liquidity. Ask yourself what it would cost to exit a position if trading volume fell 90 percent tomorrow-because for most new tokens, this is likely to happen.

The disturbing summary: The industry has been extremely successful in solving an attack, and the attacker has moved. Locking in liquidity remains the true protection against the specific threats it targets, but treating it as a universal security signal is now exactly the mistake it was meant to prevent.

The rule that this model fits

Beyond the token itself, this case illustrates a recurring phenomenon in the field of cryptographic security that is worth mentioning because it will happen again.

Security engineering in this industry is often hostile and specific. When a particular attack causes enough damage to become notorious, its builders design a mechanism to precisely stop it, that mechanism becomes the standard, and the ecosystem regards its existence as evidence of universal security. Then the attackers--who had read the same documentation--designed around it. The mechanism continues to work as expected, but the security inference no longer holds true.

The same sequence produces audit badges-which prove that specific code has been reviewed but is interpreted as proving that the project is legal. It creates a waiver of ownership-it removes the administrator's ability to modify contracts, but is interpreted as eliminating risk, while making no statement about contracts that were originally written in bad faith. It creates multi-signature escrow-which prevents a single compromised key from draining funds, but is interpreted as institution-level security without saying who holds the key. In each case, the mechanism was real and valuable, universally adopted, but ultimately became uninformative-a pattern of mechanism design meeting enemies that has emerged repeatedly in the industry, precisely because it was once successful: once everyone had it, having it made no distinction between anyone.

The corollary is practical. Any security signal that becomes a check box counts down, starting from the moment the signal becomes standard, not the moment the attack defeats it. The check box for every item in a category is no longer a filter, no matter what it still prevents. The useful question is never whether tokens have standard protections, but what risks those protections have never been designed to touch-and that list is always longer than the list.

Concluding remarks on how to view locking from now on

Because this mechanism will not disappear, nor will the design built on it.

The correct mental model is a lock on a store door. It prevents one specific thing-someone removes inventory at night-and is really worth having. But it doesn't tell you whether what the store sells is useful, whether the owner is honest, whether the price is fair, or whether the store will still exist next month. No one walks into a strange store, observes a lock on the door, and concludes that the product is good. That's roughly the inference encouraged by the standard token list, and the launch pad made the situation worse by automatically attaching the same lock to every door.

The key to changing assessments is knowing who benefits from your entry into the store. On a platform, if the token creator collects a fee from every transaction in the store-including transactions where you sell something you regret buying-then the lock on the door is not there for you. It exists because it makes the arrangement last, and persistence is what the operator needs. Interpreting it this way costs no cost, but prevents the specific errors described in this guide.

FAQs

What does locking in liquidity mean?

Liquidity provider tokens representing deposited assets in the trading pool are deposited in a time-locked contract that cannot be withdrawn by the creator within a specified period. This prevents carpet fraud-where creators redeem these tokens, remove valuable assets from the pool, and expose holders to unsaleable tokens. Lockdown can be verified on-chain through a lockdown platform.

Does locking in liquidity mean that tokens are safe?

No. It means that a specific attack has been prevented. It doesn't say how supply is distributed among holders, what rights the token contract grants to its owners, how long the lock-up lasts, who receives the pool's transaction fees, or whether the token will have enough liquidity for you to exit at a reasonable price next week.

Can liquidity-locked tokens still be a scam?

Yes, and more and more designs are built around locking in rather than ignoring it. On launch pads where transaction fees are paid to token creators, a permanently locked pool provides a continuous revenue stream for the token creator-even if the token has been publicly marked as fraud and the holder is selling. The creators had no incentive to pull the carpet because it was more cost-effective to charge.

Why does the launch pad automatically lock in liquidity?

Because it removes the most damaging and common failure modes, it helps the reputation of the platform and reduces a category of fear when traders engage. This has its value. The consequence is that locks on launch pad tokens do not carry any information about that specific project, because every token on the platform has locks.

What is the difference between locking in liquidity and locking in tokens?

Locking in liquidity limits is the withdrawal of assets that support the trading pool. Locked tokens use an unlocking program to limit the amount the team holds themselves and limit how quickly insiders can sell them. They target different risks, and well-functioning projects usually do both, while the security check box usually refers to only the former.

Can I still buy and sell liquidity-locked tokens?

Energy. Locks apply to withdrawing the underlying assets of the pool rather than trading against the pool. Buying and selling proceed normally, and each of these transactions incurs a fee that can be collected by the token creator on some platforms.

What should I check?

Concentration of holding of top wallets, permissions of token contracts (including minting permissions and ownership status), expiration dates and terms of lock-in, who receives transaction fees, and realistic exit liquidity. The screening tool can display most content in five minutes, and any of these will eliminate more bad tokens than a lock-in check. This is educational information, not financial advice.
