CoinStats is a third-party provider that allows you to sync cryptocurrency wallet balances and transactions into Sure. This integration uses the CoinStats OpenAPI to fetch data from multiple blockchain networks.

​
How it works

When you connect a crypto wallet through CoinStats, Sure syncs:
  • Wallet balances across multiple tokens
  • Transaction history
  • Real-time price data
The integration supports multiple blockchain networks including Ethereum, Bitcoin, and many others available through CoinStats.

​
Currency storage approach

All CoinStats accounts are stored in USD and will remain in USD. This design decision ensures data consistency and prevents exchange rate drift.

​
Why USD storage?

There are two possible approaches for storing cryptocurrency values: Option 1: Store in USD (current implementation)
  • CoinStats data is stored in USD
  • Values are converted to your family currency when displayed
  • Works the same way as multi-currency accounts already do in Sure
  • If you update exchange rates, values automatically update correctly without requiring a sync
  • Original USD values are always preserved
Option 2: Store in family currency
  • Convert cryptocurrency values to family currency during sync
  • Problem: If currency provider is not set up or conversion fails, data is saved with a 1:1 exchange rate
  • Once saved incorrectly, you lose the original value and cannot fix it later
  • Creates data integrity issues

​
Benefits of USD storage

The USD storage approach provides several advantages:
  1. No forex drift: Values are converted only once, preventing cumulative exchange rate errors
  2. Data integrity: Original values are always preserved
  3. Automatic updates: When you fix or update exchange rates, all cryptocurrency values update correctly without re-syncing
  4. Consistency: Works the same way as other multi-currency accounts in Sure
  5. Reliability: No dependency on currency provider being available during sync
This is why USD storage is the preferred approach and will remain the standard for CoinStats integration.

​
