HUSD token is a stablecoin that was created by a Hong Kong based company called Stable Universal. HUSD is backed by US Dollars in a 1:1 ratio that are held in a trust company. The HUSD stablecoin is designed to have a governance structure that will increase security, liquidity, and transparency. Monthly audits of HUSD's reserves are conducted by an independent accounting firm to ensure that the 1:1 backing is maintained.

TrueUSD is a stablecoin backed by USD. It was created by TrustToken, a company that specializes in creating asset-backed tokens on the Ethereum blockchain. TrueUSD is fully collateralized and is transparently verified by third-party attestations.
TrueUSD was created within a legal framework that enables users to exchange USD directly with an escrow account. The platform is powered by smart contracts that ensure a 1:1 parity between USD and TrueUSD. Escrow accounts and regulatory compliance practices enable auditing and more legal protection for token holders.
Users wire funds to these third-party escrow accounts, and an equivalent amount of TUSD is generated to their ethereum addresses. Each TUSD can be redeemed for one US Dollar, that is held in escrow.
