Sperax, also known as SPA, is an open-source development team that was established in late 2019. The team is dedicated to creating software products based on the Sperax protocol. At the heart of Sperax is the Sperax token ($SPA), which is used to power a suite of DeFi applications and the first auto-yield stablecoin, $USDs. Sperax aims to address the volatility issue that has been a hurdle for cryptocurrency adoption. By creating a stablecoin, Sperax strives to provide a solution that can be used as a medium of exchange without the high volatility associated with most cryptocurrencies.

Sperax operates by using the Sperax token ($SPA) as the core of its system. Users can mint new USDs by locking eligible collateral within the system. The protocol then mints an additional stablecoin. If the price of USDs drops below the peg, interest rates will decline, encouraging more users to burn their existing USDs and buy USDs from exchanges to burn them. This reduces the supply of USDs, pushing the price upwards. Sperax also employs a dynamic transition between algorithmic and collateralized mechanisms, adjusting the fraction of the money supply that is algorithmically determined versus the fraction that is collateralized.

Sperax aims to provide a stablecoin that can be used as a medium of exchange without the high volatility associated with most cryptocurrencies. This makes it potentially useful for a wide range of applications in the DeFi space. For instance, depositing stablecoins in a savings account can now generate positive yields for users who do not need to fear that changes in the price of the currency could offset any interest gain. Sperax also aims to implement a dual token system with a stablecoin (USDs), as well as a governance/value accrual token (SPA), providing more flexibility and potential use cases for its users.

Sperax was founded in late 2019 with the goal of addressing the volatility issue that has been a hurdle for cryptocurrency adoption. The team behind Sperax has focused on building software products based on the Sperax protocol, with the Sperax token ($SPA) at its core. Since its inception, Sperax has built the first auto-yield stablecoin, $USDs, and a suite of DeFi apps. Over time, Sperax has strived to combine elements of existing different designs, by being an algorithmic, scalable, trustless, and decentralized stablecoin protocol that operates on-chain.
