Provider scope

The connector reads Spot account balances. It does not claim universal coverage of every Binance product, wallet or subaccount.

Credential boundary

Your server sends API key and secret when connecting the user's account. ChainsFlow encrypts the credential, while your onboarding must require read-only permissions and keep trading and withdrawals disabled.

Normalized application contract

After connection, your application uses ChainsFlow account IDs and normalized portfolio responses. Provider DTOs, signing rules and asset quirks stay inside the integration adapter.

Provider-specific behavior

The Binance adapter handles Spot-only scope and non-zero balance filtering. Synchronization errors are mapped to stable safe problem codes without exposing credentials or raw provider payloads.
