The Double-Spending & FX Risk Challenge
Cross-border payments between international buyers and suppliers suffer from high transaction delays (2-5 business days), foreign exchange volatility risks, and vulnerable single-entry ledger systems open to race conditions during multi-currency conversions.
We designed an immutable double-entry escrow engine capable of locking funds in multi-currency vaults, executing automated milestone releases upon verification, and maintaining cryptographic audit trails for compliance authorities.
