description: "Stablecoin payments vs traditional rails (SWIFT, wires, correspondent banking): compare speed, cost, settlement, and reach. How BlindPay's stablecoin API beats legacy cross-border payments."
faq:
  - q: How is a stablecoin API faster than traditional payment rails?
    a: Traditional cross-border payments via SWIFT and correspondent banking can take 1-5 business days. A stablecoin API like BlindPay settles in under 60 seconds by moving value as USDC or USDT and converting to local fiat at the destination.
  - q: Is a stablecoin API cheaper than wires?
    a: Usually. Traditional wires carry fixed fees plus intermediary and FX markups across correspondent banks. A stablecoin API uses transparent FX and per-transaction fees with no pre-funding, removing several intermediaries.
  - q: Do I still get bank settlement with a stablecoin API?
    a: Yes. BlindPay converts stablecoins to local fiat and settles to bank accounts over local rails: ACH, PIX, SPEI, SEPA, SWIFT, and more: so recipients receive money in their own currency and account.

# Stablecoin API vs Traditional Payment Rails

Cross-border money movement has two paths: **traditional rails** (SWIFT, wires, correspondent banking) and a **stablecoin API** that moves value as USDC/USDT and settles to local fiat. Here's how they compare.

## Comparison

| | Traditional rails | Stablecoin API (BlindPay) |
| --- | --- | --- |
| **Settlement time** | 1-5 business days | Under 60 seconds |
| **Intermediaries** | Multiple correspondent banks | Direct conversion + local rail |
| **FX** | Markups across hops | Transparent live quotes |
| **Pre-funding** | Often required | None |
| **Cutoff windows** | Bank hours / batch | 24/7 |
| **Reach** | Varies by correspondent network | USD, BRL, MXN, COP, ARS, EUR over local rails |
| **Developer access** | Limited / file-based | REST API, webhooks, CLI, MCP |

## Why it matters

- **Speed**: recipients get funds in seconds, not days.
- **Cost**: fewer intermediaries and transparent FX.
- **Capital efficiency**: no pre-funding local accounts.
- **Programmable**: integrate in code, or let AI agents move money via [agentic payments](/agentic-payments).

## When traditional rails still apply

Some flows (large institutional settlement, specific regulatory contexts) still use legacy rails. BlindPay also supports **SWIFT** where needed: so you can mix rails through one API.
