Secured Ledger token was released in 2018 (SLRT), with the goal of creating a platform supporting a multi-faceted auditing process to take place in a public forum made up of both smart contract developers and security assessors.  The primary market gaps Secured Ledger was set to address were providing a decentralized process for smart contract security audits and making the identification and resolution of security flaws a more publicly visible exercise, helping build trust in the overall system.  Secured Ledger was ultimately wound down because of the shifting regulatory ecosystem around cryptocurrency.
