Open
https://app.unicrypt.network/ and select the blockchain in question in the "Browser" menu. Then select the "Tokens" tab instead of "Pairs" and insert the token’s contract address into the search line. Select the token in question. Then go down to the block listing the token’s trading pairs. In case the pair with the biggest liquidity is locked, then choose "Yes".
Otherwise, it’s possible that you’ll find the link to the timelock smart contract or you can also put the question in the token’s community chat and mention community manager or send directly to him the following message: "Hello! I am the Hacken Scout community member. Our project is developing the biggest database containing detailed information regarding the security of cryptoprojects that will be used by CER live, our resource that is the partner of Coingecko. Now I am collecting data about %name of the project% and I have a question: Are your LP tokens locked?". If tokens are not locked, then choose "No".
