# Upgrade to Cross Chain Address Activity API

*Published May 21, 2025*

![Upgrade to Cross Chain Address Activity API](https://www.datocms-assets.com/86369/1750368404-address-activity-improvement.jpg)

The Cross Chain Address Activity API has undergone a major performance improvement to significantly reduce the number of timeouts or `503` network error responses. The improvement stems from optimizing the unified query conducted over multiple shards.

The Cross Chain Address Activity API does a deep crawl across all supported blockchains to identify which chains a wallet is active on along with a `last_seen_at` timestamp with one API call.
