Stablecoin cards · Card funding
Rain powers stablecoin card programs on both Visa and Mastercard — the world's two largest card networks — for the enterprises, neobanks, and platforms that offer the cards to their own customers. The hardest part of any card, though, is the part before the swipe: getting value onto it. Rain works with Mesh so those programs can let a cardholder fund from the crypto they already hold — across 300+ wallets and exchanges and almost any token — in a single step, with Mesh's SmartFunding™ orchestration layer converting it to the card program's preferred stablecoin. No copying wallet addresses by hand, no switching between external tools, no multi-step process. On the Avalanche Card — a card program of the Avalanche Foundation, built on Rain and funded through Mesh — bridged routes now comprise the majority of all deposit transactions. Rain powers the spend; Mesh removes the funding friction.
Deposit and bridging figures per Mesh transfer data, June–July 2026. Network figure (300+ wallets and exchanges) per meshpay.com, June 2026. Merchant figure per Rain; Rain also issues on Mastercard as of May 2026.
Funding has been the friction-heaviest step for users. A holder's crypto is scattered across exchanges, self-custody wallets, chains, and tokens, almost never sitting as the exact stablecoin on the exact chain a card settles in. Conventional funding makes the user do the reconciliation: withdraw, pick a network, convert or bridge, fund gas, copy a long address between apps.
Every step is a place to drop off — and in the emerging markets these card programs serve, where the value proposition is turning crypto into spendable dollars, that drop-off is the difference between a card that gets used and one that doesn't.
Rain provides the card infrastructure end to end for the platforms that run the programs. As a principal member of both Visa and Mastercard, Rain can issue directly for its clients' programs — without stacking bank partners — which is how new programs stand up quickly.
Through one integration, SmartFunding™ connects the cardholder's existing wallets and exchanges, reads what they hold, routes and converts it, and delivers a single settled deposit in the card program's preferred stablecoin — combining up to five funding sources from a connected account into one transaction. Two paths run through the same integration: direct wallet/exchange connection, and a manual QR deposit that supports bridged assets including BTC. Because the routing lives in Mesh's orchestration layer, Rain's programs inherit new chains, tokens, and exchanges as Mesh adds them, with no new engineering. Mesh provides orchestration, identity, and execution — never custody — so the cardholder's assets stay with them and the platforms they've connected.
The first program to run it at scale is the Avalanche Card — a program of the Avalanche Foundation, powered by Rain and live across many U.S. states, Latin America, and the Caribbean. The card's deposit experience is powered by Mesh, multi-chain funding included: cardholders fund from Solana, BSC, Tron, Polygon, Arbitrum, Base, Ethereum, Optimism, Bitcoin, and more, with everything settling on Avalanche C-Chain behind the scenes.
Within weeks of the routes being available, bridged deposits were carrying nearly half of the card's deposit transactions and a majority of its deposit volume, according to Mesh transfer data. Bridged transactions soon crossed the majority line — and have held it week after week. The card's biggest total deposit week since launch came with multi-chain funding in place, in a week where native C-Chain deposits set their own record too. Both sides grew at once — multi-chain funding added activity rather than shifting it.
The cardholders it reaches are exactly the ones who couldn't participate before: BSC leads bridged deposits on both count and dollars, driven by stablecoin holders in the Binance ecosystem; Solana is the high-ticket network, averaging roughly ten times the deposit size of BSC; and Tron has accelerated into a clear third on USDT-native users.
The majority share is the point. Most of the card's deposit activity arrives through routes that would not exist without orchestration in the flow — every one of those deposits began as an asset that, to a card settling on Avalanche, was effectively stranded. SmartFunding™ makes those holdings fungible in practice: it meets cardholders where their assets already live, handles routing, conversion, and settlement invisibly, and turns "the wrong token on the wrong chain" from a dead end into a deposit. That is the difference an orchestration layer makes: funding built on Mesh converts where conventional flows leak.
"We just think that the best infrastructure solutions are invisible."
