What is the main difference between Fyatu and Rain for card issuing?

The fundamental difference is the funding model. Rain is built around a USDC prefunding model — capital is deposited into the platform before any card can transact. Fyatu's JIT model keeps card balances at $0 and fires a real-time webhook to your backend at every authorization. You approve or decline the transaction and funds are settled — no prefunding, no blockchain, no capital sitting idle in a stablecoin pool.

Does Fyatu support crypto-funded cards like Rain?

Yes. Fyatu supports crypto-funded card programs without requiring blockchain integration. You hold your users' USDT, USDC, or any crypto balance in your own ledger system. When a card transaction fires, Fyatu sends a webhook to your backend — you check the ledger balance, approve the transaction, and Fyatu settles in fiat. The blockchain never enters the card network path. Rain routes USDC through smart contracts; Fyatu keeps it off-chain entirely.

Can I use Fyatu in markets where Rain isn't available?

Yes. Rain's stablecoin-prefunding model is optimized for crypto-friendly markets. Fyatu operates in 180+ countries without requiring blockchain access, making it viable in LATAM, MENA, Eastern Europe, and other regions that suit fiat-based card infrastructure.

How does stablecoin exposure differ between Rain and Fyatu?

With Rain, your card program is backed by USDC balances held in the platform, so stablecoin conditions directly affect your program's funding. With Fyatu, there is no stablecoin balance at the card infrastructure level. Your backend manages balances in whatever denomination you choose; Fyatu settles in fiat through the card network. Stablecoin risk stays in your application layer where you can manage it explicitly.

How long does it take to go live with Fyatu vs Rain?

Fyatu sandbox access is available immediately after registration — you can issue test cards and fire authorization webhooks within minutes. Production onboarding takes days, not weeks. Rain requires USDC pool setup, smart contract configuration, and compliance review, which extends the onboarding timeline. Fyatu's pure REST + webhook model means the integration is a standard backend development task with no Web3 expertise required.

WHAT MAKES FYATU DIFFERENT

Fyatu and Rain: different architectures

What distinguishes Fyatu's infrastructure for modern card programs.

Zero capital lock-up

Rain's model is built around prefunded USDC — capital is deposited into the platform before cardholders can spend. With Fyatu JIT, your cardholders can carry a $0 balance until the exact moment of authorization: funds are pulled from your backend in real time. No idle capital, no opportunity cost.

No blockchain integration required

Rain's stablecoin approach uses on-chain USDC token transfers for funding — a natural fit for Web3-native architectures. Fyatu takes a different path: a pure REST API and HTTPS webhook stack, with no wallet, no smart contracts, and no chain dependency. For card programs that want infrastructure that stays entirely off-chain, Fyatu is purpose-built for that use case.

Global-first coverage

Rain's on-chain funding model is optimized for crypto-friendly markets. Fyatu operates across 180+ countries including LATAM, MENA, Eastern Europe, and other regions where card programs benefit from fiat-based infrastructure — without requiring blockchain access. One API, one contract, global coverage.

Real-time authorization control

Fyatu fires an HTTPS webhook to your backend at every authorization before it settles. You can approve, decline, or modify the amount based on live KYC status, custom balance logic, MCC restrictions, or any business rule — in under 100ms. Rain's model offers configurable rule-based spend controls, which works well for simpler authorization logic but doesn't support a real-time backend callback per transaction.
