Let us start with understanding what is liquidity for cryptocurrency and why you may want to lock it. Liquidity, simply put, is a pool of funds that crypto token developers need to create to enable their investors to buy and sell instantly. Without this pool, the investors will have to wait for someone to match their buy or sell order and there is no guarantee that the trade will be completed at all. Liquidity is created by pooling in the new token along with another token of established value (e.g., ETH or BNB or stablecoin like Tether) in an exchange like Uniswap or PancakeSwap. This pool of funds gets deposited in the exchange and liquidity provider receives liquidity pool (LP) tokens in return, which can be used at a later point to withdraw the pool funds.

Why should liquidity be locked? If liquidity is unlocked, then the token developers can do what is infamously known as “rugpull”. Once investors start buying token from the exchange, the liquidity pool will accumulate more and more of coins of established value (e.g., ETH or BNB or Tether). This is because investors are sending these tokens of value to the pool in the exchange, to get the new token. Developers can withdraw this liquidity from the exchange, cash in all the value from the pool and run off with it. Liquidity is locked by renouncing the ownership of liquidity pool (LP) tokens for a fixed time period, by sending them to a time-lock smart contract. Without ownership of LP tokens, developers cannot get liquidity pool funds back. This provides the confidence to the investors that the token developers will not run away with the liquidity money. It is now a standard practice that all token developers follow, and this is what really differentiates a scam coin from a real one.

What to keep in mind while locking liquidity

Alright, so locking liquidity is important, we get it. But as developer, how do we go about it. Let us talk about some of the questions you might have on your mind:

1. How long should I lock my liquidity pool tokens for? To provide necessary confidence to the investors, a minimum of one year and ideally a three- or five-year lock period is recommended. This would also allow ample time for your coin to grow to a scale where investors will pool in liquidity, and nobody would be really worried about a rug pull by the owners.

2. How much liquidity I should lock? Liquidity is the first thing that your investors check for and anything which stands out might make them uncomfortable. Ideally you should lock all your liquidity, and at minimum 80%. Otherwise, many token scan tools like Mudra Research and poocoin will start flagging your token.

3. Will locking liquidity hamper trading of my token? Not at all, you are locking your liquidity tokens and not your original tokens. Investors can freely exchange your token and even more so with confidence.

How do I lock liquidity?

Liquidity is locked by depositing the liquidity pool (LP) tokens in a time-lock smart contract. Some token owners deploy their own time-lock contract, however since it is custom contract, this practice is not well trusted. The ideal way is to use a reputed third-party locker.
