This project seems to have been abandoned for a long time. The SLT currency is a token based on the ERC20 network, and based on the block explorer of this contract, the low transaction activity of this network can be noticed (check the screenshots below the review).
The main project website is not available and the website is one of the most important features whose activity is very important for the survival of a project.
The sociallending Twitter page has not been active since 2018, and according to the chart of changes in the price of SLT currency, it can be seen that it was released a long time ago, because the price has been at the lowest prices for a long time and will decrease over time.
