v3.2Mar 3, 2026Reconstructed

Event-time USD valuation for flow amounts

Flow USD amounts moved from run-time spot pricing to event-time historical price attribution when available.

Impact snapshot

  • Event valuation now prefers daily historical prices from `supply_history` at event day
  • Price provenance persisted per event (`price_used`, `price_timestamp`, `price_source`)
  • Row-drop accounting added for malformed/dust logs to improve data quality observability

Alchemy migration and chain-aware scan controls

Mint/burn ingestion migrated to Alchemy JSON-RPC with chain-specific scan behavior and stronger timestamp resolution guarantees.

  • Replaced Etherscan log ingestion with Alchemy `eth_getLogs`
  • Block timestamps now resolved in batch via `eth_getBlockByNumber`, with retry-on-missing semantics
  • Scan ranges and safety margins calibrated per chain (including Optimism support)

v3.0Mar 2, 2026Reconstructed

reUSD multi-chain coverage and per-coin dedup correction

Coverage expanded to Re Protocol reUSD across four chains, then corrected aggregate dedup logic to avoid multi-contract over-weighting.

  • Added reUSD mint and redemption event tracking on Ethereum, Arbitrum, Base, and Avalanche
  • Added nth-data-slot amount decoding for non-standard event payload layouts
  • Aggregate flow loop now deduplicates by stablecoin ID to prevent duplicated rows and weighted overcounts
