About SPA
Sperax USD protocol mints USDs, a 100% collateralized stablecoin. USDs is backed by on-chain collateral and generates organic yield for its holders. USDs is a stablecoin that generates auto-yield natively. Currently, USDs is live on Arbitrum, the largest Layer-2 Ecosystem of Ethereum. Eventually, Sperax will build a system of interoperability so that USDs will be natively deployed to all major blockchain platforms.
SPA holders can stake SPA tokens on either Arbitrum or Ethereum and receive veSPA tokens which are nontransferable. veSPA balance is proportional to the lockup period, meaning if user locks up for a higher duration they receive proportionally more veSPA tokens. veSPA balance determines the share of staking reward and voting power.
What is Automated Market Making (AMM)?
Automated market making (AMM) can calculate the buying and selling price according to the formula, so as to provide a continuous quotation for the market. CoinEx combines AMM with the order book, which means the liquidity pool will be automatically converted into the order book. With the "constant product market maker formula" algorithm in AMM, no matter how large the order book is or how small the liquidity pool is, firm liquidity provision to the market can be guaranteed.
