Best Practices for Locking Liquidity: 2025 Guide

Locking liquidity is a critical best practice for new crypto tokens, serving as a safeguard against scams and a signal of trustworthiness to investors. Whether you’re a general crypto enthusiast or a token developer, understanding liquidity locking can help you protect funds, prevent rug pulls, and build community confidence. This detailed guide covers everything from what liquidity locking means to how to do it effectively, including recommended lock durations, amounts, and top services to use.

What is Liquidity Locking?

Liquidity locking refers to the practice of restricting access to a project’s liquidity pool funds for a set period of time. When developers create a token and provide liquidity on a decentralized exchange (DEX) like Uniswap or PancakeSwap, they receive liquidity provider (LP) tokens in return. These LP tokens represent ownership of the liquidity pool (the paired funds in the DEX). Locking liquidity involves sending those LP tokens into a time-locked smart contract or third-party service, which revokes the developer’s ability to withdraw the liquidity until the lock expires​. In other words, the project team relinquishes control of the pool funds for a predetermined duration​.

By using a liquidity locker (a specialized smart contract or service that holds LP tokens securely), developers cannot pull out the liquidity on a whim. This mechanism ensures the funds in the pool remain available for trading and cannot be suddenly drained. Essentially, liquidity locking creates a public assurance that the token’s market won’t be sabotaged by the creators removing liquidity early, which is crucial for maintaining a stable market for the token​.

Recommended Lock Period (Duration)

One common question is how long liquidity should be locked. While lock periods can vary, best practices have emerged from industry experience:

• Minimum of 1 Year: To provide basic confidence to investors, a minimum lock duration of one year is recommended​. A one-year lock shows that the team doesn’t intend to pull liquidity in the short term, covering at least several market cycles and project development milestones.
• Ideally 3 to 5 Years: For even greater trust and stability, many advise locking liquidity for three to five years if possible​. A multi-year lock signals a long-term commitment – the developers plan to be around for years to come. It allows the project time to grow and gain adoption without investors worrying about a sudden rug pull by the owners. In fact, a three+ year lock is often seen as a strong positive sign that the project is serious and here to stay.

Locking for such extended periods might sound extreme, but it has become a norm for legitimate projects. Of course, teams should choose a lock period that makes sense for their roadmap (for example, aligning with major releases or planned upgrades), but longer locks generally equate to higher investor trust. Keep in mind that once the lock period expires, you should be prepared to either relock the liquidity or clearly communicate your next steps to the community to maintain confidence.

Recommended Lock Amount (Liquidity Percentage)

Besides duration, the amount of liquidity locked is another critical factor. Investors tend to scrutinize what percentage of the total liquidity pool is secured. Best practices for lock amount are:

• Lock the Majority (At Least 80%): It’s recommended to lock at least 80% of your liquidity pool tokens​. In fact, the ideal scenario is to lock 100% of the liquidity (or very close to it) for maximum transparency and trust​. Locking all or most liquidity shows you’re not holding back a large portion that could be pulled later. Many token analysis tools and scanners will flag a token if a significant chunk of liquidity is unlocked. Anything less than ~80% locked may raise red flags to potential investors, as it could indicate the team retained too much control over the liquidity.
• Avoid Tiny Unlocked Portions: If possible, lock all LP tokens received from the initial liquidity providing. Sometimes teams keep a small portion unlocked for flexibility or to add liquidity later, but be cautious – any noticeable unlocked liquidity can make investors uncomfortable​. The more you lock, the stronger the signal that you have no intent or ability to remove liquidity improperly. A token with, say, only 50% of liquidity locked will struggle to gain investor confidence compared to one with 80-100% locked.

In essence, the higher the percentage of liquidity locked, the better. It’s a simple way to demonstrate that the project’s success is tied to the token’s market, and that developers can’t easily undermine the token by draining liquidity.

How to Lock Liquidity Effectively (Step-by-Step Guide)

For crypto developers, locking liquidity is a straightforward process if you follow the right steps. Below is a step-by-step guide to locking liquidity safely using a reputable platform. This guide is useful whether you’re using dedicated liquidity locking services like Mudra Locker, Unilocker, or others:

1. Provide Liquidity on a DEX and Obtain LP Tokens: Before you can lock liquidity, you need to create a liquidity pool for your token on a decentralized exchange and get LP tokens in return. For example, you might add your token and an equivalent value of ETH (on Uniswap) or BNB (on PancakeSwap) to form a trading pair. Once you supply these funds, the DEX will mint LP tokens to your wallet, representing your share of the liquidity pool. Make sure those LP tokens are in your wallet, as those are what you will be locking​. (Tip: Only proceed with locking once you are certain you won’t need to withdraw that liquidity for the duration of the lock.)
2. Choose a Reputable Liquidity Locker Platform: Next, select a trusted third-party service to lock your LP tokens. Using a well-known liquidity locker is strongly recommended over trying to lock liquidity manually or with a custom contract​. Reputable locker platforms have publicly tested smart contracts (often audited) and a track record of security. Some popular options include Mudra Locker (great for BNB Chain projects), Unilocker (multi-chain support), Team.Finance, PinkLock, DxLock, and others​. Research the options and pick one that supports your blockchain (Ethereum, BSC, Polygon, etc.) and has a good reputation for security and transparency. Avoid unknown or unverified services, as the safety of your liquidity will depend on the locker you use.
3. Connect Your Wallet to the Locker Service: Once you’ve chosen a platform, go to its website and find the Liquidity Lock section or tool. Connect the wallet that holds your LP tokens (e.g., via MetaMask). Ensure your wallet is on the correct network for the liquidity you’re locking (for instance, switch to BSC network if using Mudra Locker for PancakeSwap LP tokens). After connecting, the platform will usually allow you to select the specific liquidity pool tokens you want to lock​. You may need to approve the LP token for the locker contract first (a one-time on-chain approval so the contract can interact with your tokens)​.
4. Configure the Lock (Amount and Duration): With your LP tokens recognized by the platform, input the details of your liquidity lock. Select the LP token pair from a dropdown or by pasting the LP token contract address, then enter the amount of LP tokens to lock. It’s best practice to lock 100% of the LP tokens you received to maximize investor trust (or at least the vast majority of them)​. Next, set the lock duration by choosing an unlock date/time. Many projects opt for at least a 1-year lock here, and you can choose longer (e.g. 2, 3, or 5 years) depending on your commitment and roadmap​. The interface typically lets you pick a date or a time period (like “1 year from now”). Double-check all details — for example, confirm that you are locking X number of LP tokens until the chosen date.
5. Confirm the Locking Transaction: Once you’re satisfied with the configuration, proceed to execute the lock. The platform will prompt you to confirm the transaction from your wallet. When you click the “Lock” or “Confirm” button, your wallet (MetaMask or others) will ask you to pay a small gas fee (in ETH, BNB, etc. depending on the chain) to finalize the transaction on the blockchain​. Approve the transaction and wait for it to be confirmed on-chain. After confirmation, your LP tokens will be transferred to the locker’s smart contract, effectively locking your liquidity until the set date. The platform should show a success message or details of the lock once complete.
6. Verify and Share Proof of Lock: After locking the liquidity, it’s important to verify that everything is correct and then share this information publicly to boost confidence. On the locker platform, check the lock details – you should see the amount of LP tokens locked and the unlock date. Most reputable services provide a public proof of lock, such as a shareable link or a certificate you can download, which indicates the token pair, amount locked, and unlock time​. Share this proof with your community: for example, post the lock certificate or link on your project’s website, in your Telegram/Discord groups, and on Twitter. This allows anyone to independently verify that the liquidity is indeed locked. Investors often look for these proofs, and seeing a known locker’s name (e.g. Mudra, Unicrypt) with a future unlock date instantly increases their confidence in the project​. Also, many listing sites like CoinMarketCap or CoinGecko ask for liquidity lock info during the listing process, so having that proof handy is beneficial.

Following these steps will ensure you’ve locked your token’s liquidity effectively and transparently. Always keep a record of when your liquidity will unlock as well (mark the date on your calendar!). When the lock period is close to expiring, plan to either extend the lock or clearly communicate your next steps to your community to avoid any panic when the unlock happens.

Choosing the Right Liquidity Locking Service

Selecting a secure and transparent liquidity locking service is just as important as the act of locking itself. There are several factors crypto developers and teams should consider when picking a liquidity locker:

• Security and Audits: The locker will hold your project’s funds, so security is paramount. Use a platform with audited smart contracts or a long history of use without hacks. Reputable lockers often have their code publicly verified or have undergone independent security audits. If a service has been used by many projects over several years without incident, that’s a good sign its contracts are safe and reliable​. Avoid new or untested lockers that haven’t proven themselves, as they could contain vulnerabilities. A trusted third-party locker strikes a balance by keeping liquidity untouchable to everyone (including the dev team) until the timer ends​.
• Transparency: A good liquidity locking service provides public proof of locks. This includes lock certificates or links that anyone can view to see the details of your locked liquidity (how much is locked and until when)​. Transparency builds trust – it should be easy for an investor to verify your lock on the platform. Ensure the service you choose has a user interface or explorer where locks are listed publicly. This way, you can show evidence of your lock to the community, and the platform itself acts as a neutral proof source.
• Reputation and Track Record: Research how well-known and trusted the service is in the crypto community. Longevity matters – if a platform has been operational for years and used by hundreds or thousands of projects, it has earned a level of trust. For example, a service like Mudra Liquidity Locker launched in 2021 and by late 2023 had facilitated over 100,000 liquidity locks for 1,000+ projects, demonstrating its reliability over time​. Look for reviews or discussions about the service. A platform with a solid track record and no history of exploits or rug-pull incidents will inspire more confidence.
• Features and Flexibility: Different lockers offer various features. Consider what you might need: Can you extend the lock duration or add more liquidity to an existing lock? Can you transfer lock ownership if your team changes? Is there a way to lock in multiple tranches? These features can be useful as your project evolves​. Also, check if the platform provides a user-friendly interface. Locking should be a quick and straightforward process, not something overly complex or technical.
• Cost and Fees: Liquidity locking usually involves a fee to the service (aside from network gas fees). Compare the pricing of different services. Some platforms charge a flat fee in the network’s native coin (e.g., a fixed amount of BNB or ETH), while others charge a percentage of the LP tokens (or even require holding a specific token). Opt for a service with reasonable fees and no hidden conditions. For instance, newer services like Mudra and Unilocker are known for being cost-effective compared to older solutions that sometimes charged high fees or required you to buy their tokens as part of the process​. Make sure the fee structure is clear and acceptable for your budget.
• Chain Support: Ensure the locker supports the blockchain your project uses. Some liquidity lockers are Ethereum-only, others support BSC, Polygon, Avalanche, etc., or multiple chains. If your project might span multiple networks, you may prefer a multi-chain locker (like Unilocker) so you can manage all locks in one place​. Using one trusted service across all chains is more convenient than juggling different platforms for each network​.

By carefully evaluating services on these criteria, you’ll choose a liquidity locking platform that is secure, trusted, and fits your project’s needs. Next, let’s look at two of the best liquidity locking services available today and what makes them stand out.

Best Liquidity Locking Services

There are several liquidity locking services in the market, but a few consistently stand out for their reliability, security, and ease of use. Here are two top choices:

Mudra Locker (Best for BNB Chain)

Mudra Liquidity Locker has quickly become one of the most recommended liquidity lockers for Binance Smart Chain (BSC) projects. Launched in mid-2021, Mudra gained popularity by offering a secure, no-nonsense way to lock PancakeSwap liquidity pool tokens. It’s known for its affordability and user-friendly interface​. Mudra charges a low flat fee (about 0.1 BNB) or alternatively a 0.5% of the LP tokens as the fee for locking, which is incredibly cheap compared to many competitors​. Despite the low cost, the platform doesn’t compromise on security or features: its smart contracts have been battle-tested with thousands of locks, and it provides a public proof of lock for every token. In fact, Mudra is widely trusted — by late 2023 it had handled over 100k liquidity locks for 1000+ projects on BSC​, and it has been featured in industry news (e.g., Yahoo Finance) for its contributions to DeFi.

Key features of Mudra Locker include an easy step-by-step locking process (just a few clicks to lock your LP tokens), the ability to extend locks or add more tokens to an existing lock, and shareable lock certificates (with QR codes) that you can show to your investors as proof of locked liquidity​. Mudra focuses solely on BSC, which is why it’s often dubbed the best for BNB Chain – it’s optimized for the BSC ecosystem and PancakeSwap liquidity. There are no extra hoops to jump through (such as needing to hold a specific token); you simply pay the nominal fee and lock your liquidity. For BSC token developers looking for a trusted, low-cost liquidity locker, Mudra is an excellent choice that balances cost, security, and convenience.

Unilocker (Best Overall Multi-Chain Locker)

Unilocker is a long-standing liquidity locking platform that is highly regarded across multiple blockchain communities. It originally launched supporting Ethereum (hence the “Uni” in the name, as in Uniswap), and over time it expanded to support multiple chains including BSC, Polygon, and others​. Unilocker is often credited as one of the pioneers of third-party liquidity locking, introducing user-friendly features that have since become industry standards. For example, it offers a quick-lock interface with one-click functions and provides lock certificates (including QR-code based verification) so anyone can validate a token’s locked liquidity easily​.

What makes Unilocker stand out is its combination of broad support and cost-effectiveness. It gives a consistent, straightforward experience whether you’re locking Uniswap LP tokens on Ethereum or PancakeSwap LP tokens on BSC. The platform has a strong reputation for security and has been used by countless projects since the early days of DeFi locks. Unilocker also gained a following for its competitive (sometimes even zero) fee model – for instance, it has at times offered very low or negligible fees for locking, making it attractive to budget-conscious developers​. On Ethereum, its flat fee has been significantly lower than some rivals that charged much more, and on cheaper chains it remains one of the most affordable options. Importantly, Unilocker does not require you to hold any specific token or meet extraneous requirements; its goal is to be a no-nonsense, dependable liquidity locker focusing on security and simplicity​.

Given its multi-chain support and proven track record, Unilocker is often considered the best overall choice, especially if you need to lock liquidity on different networks. It has maintained a dependable service with no major security issues, which is crucial. By choosing Unilocker, developers can reassure investors that liquidity on whichever chain they operate is safely locked away. Its ease of use and transparent proof system means both developers and investors can quickly check and trust the status of the locked liquidity.

(Other notable services include Team.Finance by TrustSwap, Unicrypt (UNCX), and PinkLock (for projects launching via PinkSale), among others. Each has its own fee structures and features, but they often come with higher costs or specific requirements. Mudra and Unilocker are highlighted here because they offer an excellent mix of security, affordability, and user experience that suits most projects.)

Conclusion

Locking liquidity is a fundamental best practice for any new cryptocurrency project. It ensures that the project creators cannot misappropriate the liquidity pool funds, thereby protecting investors and establishing trust from day one. By following the recommended guidelines — locking a significant portion (ideally ~80% or more) of your liquidity for a substantial period (at least 1 year, preferably several years) — and by using reputable locking services, you greatly improve your project’s credibility and stability. Both general crypto enthusiasts and developers should pay attention to liquidity locks: investors should always check if a token’s liquidity is locked before investing, and developers should prioritize locking liquidity to meet the community’s expectations and security standards.

In practice, implementing a liquidity lock is straightforward with the help of platforms like Mudra Locker, Unilocker, and other trusted services. These tools make it easy to secure your LP tokens and provide public proof of the lock, which you can share to boost investor confidence. The costs are usually small compared to the immense benefits in terms of reputation and risk mitigation. Ultimately, a locked liquidity pool means you as a developer are committing to your project’s long-term success, and you’re giving your community the peace of mind to join you on that journey without fear of sudden scams or liquidity shocks.

By adhering to these best practices for liquidity locking, crypto developers set their projects on a stronger foundation, and investors can engage with more peace of mind. In the ever-evolving world of crypto, transparency and trust are invaluable — and a solid liquidity lock is one of the best ways to achieve them.​​
