The TrueUSD is an ERC-20 token (running on the Ethereum Blockchain) and created by the TrustToken platform. It was designed to compete with Tether (USDT) in a more transparent and reliable way.
The main difference from the USDT is the requirement for TrueUSD to use smart contracts to issue or redeem TUSDs. The dollar funds supposed to guarantee the value of the tokens are also kept in a blocked bank account, which allows greater confidence in price stability.
The balances of the bank account in question are verified by regular audits and published publicly to avoid an excessive emission of tokens compared to the available funds.
