Token & asset index
Built from your selected RPC: successful contract deployments (parseable new account id in receipt return data) plus token accounts from native DEX register_pair logs. Each network + block window snapshot is written to disk (default .cache/token-index, TTL TOKEN_INDEX_CACHE_TTL_SEC, default 600s) so repeat loads do not re-walk the chain until expiry or Rescan. That is still not OBS-1: use a dedicated indexer for reorg-safe, planet-scale history.
Scan depth
The observer walks blocks with receipts and merges native DEX register_pair logs for the same heights. Matching snapshots are reused from disk for a TTL (default 10 minutes) so repeat visits are fast. Use Rescan to bypass cache and hit RPC again.
