USDJ is a meta-collateralized stablecoin. Meaning 1 USDJ is guaranteed by 1 unit of a different stablecoin, like USDC.
USDJ is pegged soely by USDC as of today, yet the infrastructure to expand the peg basket is already under development. More info on how the pegging is done and why meta-collateralization is a powerful point can be found on USDJ's Telegram channel.
Created by the team behind Tonic, USDJ's core deeply understands the needs of the crypto users and TON community in particular. USDJ is here to support further infrastructure development and provide builders with a stable, fast, and TON-native token.
