According to the source, SoFi Technologies said it will soon offer its own stablecoin on Ethereum, following the company’s re-entry into crypto last month. According to the source, the issuance on Ethereum means the token will operate as an ERC-20 asset with on-chain settlement on the ETH network. According to the source, this positioning makes Ethereum-based venues the primary rails for initial liquidity and pricing once the stablecoin goes live, a focal point for traders monitoring ETH pairs and stablecoin order books.

According to @StockMKTNewz, SoFi announced the launch of SoFiUSD, a fully reserved U.S. dollar stablecoin issued by SoFi Bank, N.A. (source: @StockMKTNewz on X).
