Rain (official site: rain.xyz), a United States-based stablecoin payments platform, has launched Rain Wallets, an embedded wallet service that lets business partners offer stablecoin accounts directly inside their own applications. The rollout extends the company's payments infrastructure beyond card spending, giving users a single balance from which they can receive, hold, send, and spend stablecoins.

The new wallets run on the same integration layer that Rain partners already use for card issuance, rewards programs, and fund transfers. According to the company, the design is intended to simplify the development of stablecoin payment services by tying wallet balances directly into existing financial products, creating one unified account for storing digital assets, making card payments, and moving money.

Non-custodial wallets, in which users retain control of their own private keys, are available to partners immediately. Rain plans to follow with custodial wallets and features that allow users to earn returns on stablecoin balances before the end of 2026.

The Wallet as the Core of Rain's Payments Stack

Rain is positioning the wallet as the central account that connects its payments services. The company built its early business on making stablecoins spendable through payment cards and is now extending that model to cover the broader movement of funds.

Under the new setup, users can receive money through virtual accounts or payment onramps, hold the resulting stablecoin balances, and spend those funds on card purchases. They can also move money to bank accounts in local currencies through Rain's offramps and payout services, with the entire flow available inside a partner's application.

Wallet balances fund Rain-issued payment cards directly, and those cards are accepted at 175 million merchant locations worldwide. For businesses, the integrated stack means a single provider covering wallet management, card payments, and money movement, potentially reducing the complexity of coordinating multiple vendors.

Rain illustrated the model with the example of a freelancer in Mexico receiving a US dollar payment from a client in the United States. The funds arrive through a virtual account and are credited to the wallet in stablecoins without any manual conversion. The freelancer can then pay with a Rain-issued card or transfer Mexican pesos to a local bank account through the company's global payout network.

Support for 12 Blockchains and Multiple Digital Assets

Rain's non-custodial wallets currently support 12 blockchain networks: Arbitrum, Avalanche, Base, BNB Smart Chain, Celo, Ethereum, Monad, Plasma, Optimism, Polygon, Solana, and ZKsync. The wallets can hold USDC, USDT, other stablecoins, and additional cryptocurrency assets on the supported networks, although available functionality varies by blockchain.

The multi-chain structure gives partners the flexibility to support different networks and stablecoins rather than depending on a single blockchain. Users access the embedded wallets through passkeys or verification codes sent to their email address or phone number, removing the need to manage a traditional seed phrase during sign-in — a requirement that has historically been a stumbling block for people new to self-custody.

Announcing the launch on X on October , 2026, Rain wrote:

A wallet used to just be where stablecoins sat. Doing anything useful with them meant stitching together separate providers to onramp, spend, earn, send, and offramp. Rain partners can now offer their customers all of that from one wallet, with one integration.

Open Infrastructure for Existing Wallet Providers

The platform has also been designed to work with third-party infrastructure. Businesses that already use external wallet providers, including non-custodial wallet services, can connect those wallets to Rain's card issuance, rewards, onramp, and payout products without switching to Rain Wallets. Partners that adopt Rain's wallets, meanwhile, receive integrated card funding capabilities as part of the broader platform.

Pooja Shah, Rain's head of product, said businesses introducing stablecoins to their customers need to provide users with a place to store their digital assets. Integrating the wallets with the company's other services, she explained, makes balances available for spending and transfers as soon as funds arrive. Businesses can use Rain for their entire payments infrastructure or retain existing wallet providers while connecting to Rain's services.

Stablecoin Payments Move Beyond Card Spending

The launch reflects a broader effort to make stablecoins function more like conventional money within consumer and business applications. Rather than treating digital assets solely as instruments for storage or transfers, Rain is connecting them to everyday payment activities.

By combining wallet balances with card issuance, onramps, offramps, and payouts, Rain aims to support the full stablecoin payment lifecycle, from receiving funds to spending them or converting them into local currencies. The planned introduction of custodial wallets and earning features before the end of 2026 could further expand the options available to businesses building stablecoin-based financial products. How quickly those features arrive, and how functionality broadens across the 12 supported networks — where capabilities currently differ by chain — will indicate how much of the payments stack a business can ultimately consolidate with a single provider.

The company's strategy centers on giving partners flexible infrastructure while allowing users to manage digital funds through familiar application interfaces.
