Tzero

tZero emerged from Overstock.com's blockchain ambitions as a regulated alternative trading system (ATS) for digital securities. The company positioned itself at the intersection of traditional capital markets infrastructure and blockchain-based tokenized assets, offering trading and settlement rails for security tokens. Over time, tZero expanded into NFT liquidity infrastructure and launched a payments platform (tZero Payments, operated by Niobe Payment Services LLC), signaling a broader ambition to become a payments and digital-asset settlement layer.
