KeyExpired

Error Removed v361 → v385 (removed) 30.5

The encryption key epoch for this submission has expired.

Encountered by: developerswalletsstakers

Why This Error Exists

Keys rotate every block. If you encrypt with block N's NextKey but submit at block N+2, the key has rotated twice and your encryption uses an expired epoch.

From Chain Metadata

The MEV‑Shield key epoch for this submission has expired and is no longer accepted.

What This Means

The encryption key epoch for this submission has expired.

Common Causes

  • Too much time passed between encryption and submission
  • Used old cached NextKey instead of fetching fresh
  • Block time advanced faster than expected

How to Fix

  • Fetch fresh NextKey immediately before encrypting
  • Submit encrypted transaction promptly
  • Don't cache encryption keys across blocks
