Single Dog Swap Token, abbreviated as SDST, is the sole governance token of the decentralized exchange SingleSwap, and also a sub-cryptocurrency of Single Dog (SGDOG). The total supply of SDST is 21,000 tokens, with no private placements, no airdrops, and no additional issuances ever, all minted through mining. The daily output decreases by half each year to ensure scarcity. SDST is produced through a "dual mining mechanism" involving liquidity mining and trading mining by adding SGDOG/HT and SDST/HT pools. SDST can participate in pool mining, allowing multi-mining with one token to mine various mainstream cryptocurrencies.
