# What is the purpose of $SSL?

When developers list their tokens on decentralized exchanges and start a pool, they receive LP tokens. These LP tokens can be moved around just like any other tokens on the blockchain where they were created, or even transferred to a different blockchain. Using a $SSL, the developer can place these LP tokens into a smart contract. This action temporarily removes their ability to transfer the LP tokens from a specified start date until an end date. Liquidity lockers are common for most of the well-known blockchain networks, except for the Solana chain. This is precisely where $SSL comes into play, filling that gap and providing a crucial service that was missing for projects on Solana.
