Use Cases
The New Era of Digital Banking: A Finance World Aligned with Crypto
The banking sector is no longer limited to managing fiat currencies.
Users now want to view their traditional accounts alongside their crypto holdings, connect their investments with digital wallets, and track real-time asset values.
atWallets is the technological bridge behind this transformation.
We do not provide direct crypto services to banks — instead, we deliver the secure, scalable, and compliance-ready integration and data management layer that connects digital banks to the crypto ecosystem.
What We Provide for Digital Banks
atWallets integrates banks’ existing financial systems with the blockchain world. This allows digital banks to offer customers crypto asset visibility, price tracking, and historical data — all within their own banking interface.
Integration Layer
- Multi-exchange connectivity (Binance, Coinbase, Kraken, Bitstamp, OKX, KuCoin, etc.)
- Real-time price and balance synchronization
