Within the same week, SoFi launched bank-issued stablecoins to 14.7 million users, and Cash App gradually opened USDC payments to nearly 60 million users. Stablecoins are no longer just arbitrage tools for exchanges but are becoming the underlying channels for retail finance.

SoFi's SoFiUSD operates on Ethereum and Solana, backed by bank balance sheets, and users can use it directly within the app. Cash App's USDC supports four chains, allowing users to deposit USDC to top up fiat balances or withdraw. Both companies have millions of users and regulatory compliance frameworks, which means the competition among stablecoins has shifted from "who issues" to "who reaches."
The structural change behind this is: traditional financial institutions are reconstructing user access with stablecoins. As a regulated bank, SoFi's stablecoin is essentially an on-chain equivalent of deposits; as a payments giant, Cash App treats USDC as a supplement to fiat currency channels. Both are doing the same thing—enabling users to seamlessly switch between fiat and crypto assets without leaving the app.
But the risks are also obvious: bank-issued stablecoins may face stricter capital requirements and liquidity constraints. If SoFiUSD's reserve management encounters issues, or if regulatory authorities halt Cash App's USDC channel, user trust could collapse instantly. Additionally, retail users' understanding of stablecoins still remains at the "digital dollar" level; market volatility or de-pegging events could trigger panic withdrawals, impacting the entire system.
The retailization of stablecoins is an irreversible trend, but its fragility lies in this—when millions of users are using it simultaneously, any technical or compliance issues will be amplified.
