# Known Issues

> Persistent, known data caveats — usually upstream — affecting specific chains or tables, tracked separately from live operational status.

This page lists persistent, known data caveats — usually upstream. They're tracked here rather than as a perpetually-degraded component so the [Status Page](https://status.dune.com/) reflects only current operational health.

<Info>
  Live outages and short-lived degradations show on the [Status Page](https://status.dune.com/), not here. An item stays on this list until it's actually resolved.

## Current known issues

* **Fantom** — \~900k historical `fantom.traces` are inconsistent due to a bug in the legacy go-opera client: error messages and `success = false` on successful transactions, and missing `from`, `value`, and `input`. Historical data only; current data is unaffected.
* **Near** — `near.balances` and `near.circulating_supply` have received no new data since 2026-04-17; other NEAR tables update normally. Queries depending on them return outdated results until ingestion is restored.
* **zkSync** — a client issue leaves trace coverage incomplete, affecting `zksync.traces`, `zksync.creation_traces`, and all decoded tables for function calls. Waiting on zkSync.
