WHAT MAKES FYATU DIFFERENT
Fyatu and Interlace: different architectures
What distinguishes Fyatu's infrastructure for modern card programs.
Truly global — not just Asia-Pacific
Interlace is built for Singapore and Hong Kong fintech ecosystems — a strength for programs in those markets. Fyatu operates in 180+ countries including LATAM, MENA, Eastern Europe, and other high-growth regions where card issuing infrastructure has historically been limited. For card programs that need global coverage beyond Asia-Pacific, Fyatu provides a single API and one contract.
Zero prefunding, zero capital tied up
Interlace uses a USDC prefunding model for card programs. For a $1M program, that means $1M+ in stablecoin committed ahead of spending. Fyatu JIT means the only capital you commit is what your cardholders actively authorize at the moment of the transaction — nothing sits idle in a pool.
No blockchain integration required
Interlace's funding model is built around USDC on-chain flows — a natural choice for crypto-native fintechs. Fyatu takes a different path: HTTPS webhooks and REST with no wallet, no chain, and no smart contract. For card programs that don't want to build or maintain a blockchain integration, Fyatu removes that dependency entirely.
Faster time to market
Interlace is enterprise-oriented, with onboarding aligned to that structure. Fyatu provides immediate sandbox access, a documented REST API, and a webhook-based integration that backend developers can complete without specialized Web3 expertise — reducing time to first card from weeks to days.
