Excerpt

Chainscan — Etherscan V2 unified explorer skill

Query any major EVM chain's block explorer via the Etherscan V2 unified API, with Foundry cast as a fallback for paid-tier endpoints. One Etherscan.io API key works across every supported chain through V2 — BscScan/PolygonScan/etc. keys do not work and are no longer needed.

Etherscan V1 was deprecated 2025-08-15. V2 is the only API path going forward.

Configuration

Base URL:        https://api.etherscan.io/v2/api
API key:         {{vault:ETHERSCAN_API_KEY}}
Auth pattern:    &apikey={{vault:ETHERSCAN_API_KEY}}
Chain selector:  &chainid=<id>   (REQUIRED on every call — no default)
Free tier:       3 req/sec, 100k req/day
