📌 Rain launches stablecoin wallets for fintech apps. Rain launched embedded stablecoin wallets for partner apps. One balance lets users get paid, spend with a Rain card at 175M merchants and send money in 50+ currencies. Each user gets a non-custodial wallet inside the partner's app through Rain's SDKs, with passkey sign-in, no seed phrase and sponsored gas. Neither Rain nor the partner can access the keys. Wallets run on 12 chains and hold USDC, USDT and other stablecoins. Custodial wallets and yield on balances are planned by the end of 2026. Rain, valued at $1.95B in January, also runs Western Union's Stablecard program.
