Why Stablecoins for Cross-Border Payments
Traditional international wire transfers rely on a chain of correspondent banks, each introducing fees, delays, and operating-hours constraints. Stablecoins eliminate most of this friction. When you initiate a cross-border payment through RemitFlex, the value moves on-chain — settling on a blockchain ledger rather than traversing the SWIFT network. The practical benefits for your business are significant:- Speed — On-chain settlement completes in seconds to minutes, compared to 1–5 business days for traditional wires.
- Cost — Blockchain transaction fees are a fraction of correspondent banking charges. RemitFlex passes these savings directly to you.
- 24/7 availability — Blockchains don’t observe weekends or bank holidays. Your payments can move any time, any day.
- Transparency — Every transaction has an immutable on-chain record you can verify independently.
- No correspondent delays — Value moves peer-to-peer on the ledger, removing the need for intermediary banks to batch, reconcile, and forward funds.
Supported Stablecoins
RemitFlex supports four stablecoins across its payment corridors. Each has different issuers, network availability, and use cases — the right choice depends on your target corridor and recipient requirements.- USDC
- USDT
- PYUSD
- EURC
USD Coin (USDC) is a fully reserved, USD-pegged stablecoin issued by Circle and governed under the Centre Consortium standards. It is the primary stablecoin in the RemitFlex ecosystem.
| Property | Details |
|---|---|
| Peg | 1:1 USD |
| Issuer | Circle Internet Financial |
| Token Standard | ERC-20 (Ethereum), also available on Solana, Base, Avalanche |
| Reserves | 100% cash and short-duration US Treasuries, attested monthly |
| Best For | Most RemitFlex corridors; default for USD-source payments |
How RemitFlex Abstracts Blockchain Complexity
You never need to manage wallets, gas fees, private keys, or blockchain nodes to use RemitFlex. The platform handles all on-chain operations internally. From your perspective, sending a cross-border payment looks exactly like calling a REST API endpoint — because that’s all you need to do. Here’s what RemitFlex manages on your behalf:Wallet Infrastructure
RemitFlex maintains a network of custodial wallets and liquidity pools across supported chains. You interact with logical payment objects, not raw blockchain addresses.
Gas Fee Optimisation
On-chain transaction fees (gas) are calculated and paid automatically. Your pricing is based on RemitFlex’s flat or corridor-based fee schedule, not fluctuating gas markets.
Chain Selection
RemitFlex routes transactions across the optimal blockchain network for each corridor — choosing between Ethereum, Solana, Base, or others based on speed, cost, and liquidity.
On-Chain Confirmation
The platform monitors confirmation depth for each transaction and only marks a payment as
settled once it meets the minimum block confirmations required for that network.Settlement and Your Integration
RemitFlex processes all on-chain settlement asynchronously in the background. When you create a payment via the API, you receive an immediate response with a payment object and apending status. As the payment progresses through the stablecoin rails, RemitFlex emits webhook events to your configured endpoint so your system stays in sync without polling.
Your API integration never references blockchain transaction hashes, wallet addresses, or token contracts unless you explicitly request on-chain metadata for audit purposes. The
/payments/{id} endpoint exposes an optional onchain_details field for that use case.
