    We've identified an issue causing some external Base Sepolia (Testnet) nodes to periodically fall out of sync with the tip of the chain. This issue is isolated to our test network — Base mainnet is unaffected, and all funds remain safe. We're actively investigating the root cause and will provide updates as we learn more. If you're operating a Sepolia testnet node, no action is needed at this time. We'll keep you informed as we make progress toward a resolution.
