FX

Foreign exchange in multi-currency fintech and stablecoin corridors

FX in tokenised stacks

Even when users hold a regional asset like XOFC, treasury often holds USDC or EURC for global liquidity. FX appears at on-ramp (user pays USD, receives euro or CFA-pegged balance), swap (USDC ↔ XOFC), and off-ramp (convert balance, pay local fiat).

Quote vs execute

Good FX integration separates quote from execute:

  1. Quote returns rate, fees, expiry timestamp
  2. User accepts within window
  3. Execute locks rate and initiates conversion

Stale quotes cause revenue leakage or user disputes. PayLink Swap and AutoRouter follow this pattern for cross-asset moves.

Hedging treasury

If you hold multi-currency float across USDC, EURC, and regional assets, define hedging policy—natural offset via flows vs explicit forward contracts. LP partners may offer inventory; monitor concentration risk.
