Rain wallets make stablecoin balances central to payment stack

Key takeaways
In an Oct. 13, 2026 New York release distributed by PRNewswire and first appearing on BitcoinWorld, Rain, the global stablecoin payments platform, announced Rain wallets: embedded stablecoin wallets partners can offer inside their own apps. The account is the center of Rain’s full-stack platform, connecting a stablecoin balance to cards, virtual accounts, rewards, onramps, offramps and payouts.
Partners can offer non-custodial Rain wallets today, where users hold their own keys. Custodial wallets and earning features for stablecoin balances are planned before the end of the year. Rain wallets support twelve blockchains and can hold USDC, USDT, other stablecoins and crypto assets, with functionality that may vary by network.

What happened
Rain said companies bringing stablecoins to users want them to work like any other money, so a balance must connect to every action a user wants to take. The wallet is accessible through the same integration that issues cards, powers rewards and supports money movement, letting users get paid, save, earn, spend and send from one stablecoin balance, covering the full life cycle from the moment money arrives to the moment it is spent or sent. Balances natively back Rain-issued cards, accepted at any merchant that accepts Visa or Mastercard, enabling spending at 175 million merchant locations worldwide. Partners can embed the wallet and let users sign in with a passkey or a code sent to email or phone instead of a seed phrase.
Rain described a freelancer in Mexico paid by a US client. Her dollars arrive in a virtual account and land in a Rain wallet as stablecoins without manual conversion. She can spend that afternoon with a Rain card at 175 million merchant locations, access earning options in the app, or send pesos to a local bank account through Rain’s global payouts. The experience stays inside the partner app and is powered by Rain’s infrastructure.
Pooja Shah, Head of Product at Rain, said users first need a place to hold stablecoins, and Rain wallets are that place. She said every balance is ready to use the moment it arrives because the wallet is integrated into the broader Rain stack, and partners can either use all of Rain or keep an existing wallet and connect it to the rest of the platform.

Market context
Rain started by making stablecoins spendable through cards and is now powering all onchain experiences through the wallet. A balance can arrive through a virtual account or onramp, fund a card, be put to work and be sent to a bank account in local currency without leaving the partner app. For enterprises, that means one vendor integrating the full flow of funds, with each product working alongside products already in use.
The platform is also open. Partners already working with a wallet provider can connect it to Rain’s cards, rewards, onramps and payouts. Rain wallets support multiple stablecoins and other crypto assets across major blockchains: Arbitrum, Avalanche, Base, BNB Smart Chain, Celo, Ethereum, Monad, Plasma, Optimism, Polygon, Solana and ZKsync. If partners choose Rain wallets, card funding is built in; if they keep third-party non-custodial wallets, Rain cards and the rest of the stack still work with existing infrastructure.
Rain says its technology lets partners move, store and use stablecoins instantly and compliantly through global payment cards, rewards, on/offramps, wallets and cross-border rails. As a Visa and Mastercard Principal Member, Rain issues cards accepted at more than 175 million merchant locations in over 220 countries and territories. It is built natively for stablecoins and trusted by more than 100 organizations worldwide, delivering secure, scalable infrastructure that makes money move freely and instantly around the world.

Why it matters
The shift from a payment rail to an account layer changes how stablecoin products are packaged. Instead of users holding a balance in one tool, funding a card from another and converting currency through a separate service, Rain is trying to make one stablecoin balance the base layer for saving, spending, earning and sending. That may reduce friction for businesses offering stablecoin payouts, cards or cross-border services.
It also gives users a familiar entry point: passkey or email/phone sign-in rather than a seed phrase, while non-custodial wallets still let users hold their own keys. The open integration keeps existing wallet providers in play, lowering switching costs for partners that already have custody infrastructure.
There are limits. Rain is a financial technology company, not a bank, and banking services for virtual accounts are provided by Rain’s partner banks. Card issuance availability varies by market. Wallet, virtual account and future earning capabilities vary by jurisdiction. The ability to earn additional value is provided by third-party providers and is not guaranteed.

What to watch
The near-term question is whether Rain can move from non-custodial embedded wallets today to custodial wallets and earning features before the end of the year without access uneven across jurisdictions. Partners need to know which of the twelve blockchains provide full functionality and which stablecoin assets work on each network.
Another signal will be how quickly existing partners add Rain wallets while keeping third-party wallets connected. Because Rain cards already work at 175 million merchant locations, the wallet’s value depends on whether the balance becomes the default account for payouts, spending, saving and cross-border transfers in partner apps. Rain presents the account as the center of its platform, while earnings remain future-facing and subject to jurisdictional conditions.
