USDJ is a fully collateral-backed currency whose value is kept stable relative to the US Dollar through a series of aligned financial incentives.
The currency lives completely on the blockchain; its stability is unmediated by any locality, and its solvency does not rely on any trusted counterparties. All circulating USDJ are backed by a surplus of collateral that has been escrowed into audited and publicly viewable TRON smart contracts.
Once generated, USDJ can be used in the same manner as any other cryptocurrency. It can be freely sent to others, used as payments for goods and services, or be held as a hedge against market volatility.
