Supported account scope
Bybit is read from its Unified Account; Kraken is read from its account balance. The distinction matters because assets held in unrelated products are not guaranteed to appear in either portfolio total.
Credential setup
Bybit uses API key and secret. Kraken uses API key and private key. In both cases the credential should be dedicated to portfolio tracking and limited to the minimum account-reading permissions.
Normalization differences
The Bybit connector handles unified wallet balance details, while the Kraken connector handles provider-specific asset codes and suffixes. Both outputs become the same normalized asset-position model before aggregation.
Using both together
A multi-exchange view is most useful when connection identity remains visible. ChainsFlow keeps per-exchange synchronization state and does not hide a provider error behind an apparently complete combined total.
