Binance, a blockchain company that runs a large digital asset exchange, launches zero-commission tradable stock tokens in a move that combines traditional capital markets with cryptocurrency-based transactions.The company is working with CM-Equity AG, a licensed investment firm in Germany, and Swiss-based Digital Assets AG, an asset tokenization platform.Each digital token represents one share of equity stock and is fully backed by a depository portfolio of underlying securities that represents the outstanding tokens. Users will be able to trade fractional tokens.The first stock tokens announced will be of Tesla (TSLA), and the minimum trade size is one-hundredth of a stock token, representing the same fraction of a Tesla share.Stock tokens are priced and settled in Binance USD (BNB-USD), a regulated stablecoin pegged to the U.S. dollar and issued by Paxos Trust Company.
