The term STO stands for:
Security token offering
STO or Security token offering is similar to an IPO, an STO aims to issue security tokens that are subject to regulation. Compared to utility tokens, security tokens are thus considered investment instruments. Many of these tokens are based on Ethereum’s ERC-20 standard, which is enhanced by KYC and compliance functions (e.g., ERC-1404, ERC-1410).
