+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Safe Transaction Service API was returning 429 errors when checking all 7 chains in parallel. Added retry with exponential backoff (up to 4 retries, 1s/2s/4s/8s delays) and staggered chain detection (150ms gaps) and data fetching (200ms gaps) to avoid rate limits.
