Etherscan is pulling free access to its Gnosis Chain API. Starting soon, only paid Pro tier subscribers will be able to query Gnosis Chain data through the platform. The company also confirmed that Gnosisscan, the dedicated block explorer for Gnosis Chain, will be deprecated in August 2026.
What the API change means for developers
Developers who've been using Etherscan's free API to pull transaction data, token balances, or contract information from Gnosis Chain will need to upgrade to a Pro plan. Etherscan hasn't released specific pricing yet, but the move effectively ends free public access to Gnosis Chain data through its service. That could push some projects to switch to alternative explorers or run their own nodes.
Why Gnosisscan is being deprecated
Gnosisscan launched as a separate explorer tailored to Gnosis Chain. Now Etherscan is folding that functionality into its main platform. The deprecation date — August 2026 — gives users more than a year to adjust. After that, Gnosisscan will stop working, and all Gnosis Chain data will live on Etherscan's site.
Timeline and next steps
Etherscan hasn't said exactly when the API tier change takes effect. But the Gnosisscan shutdown is set for August 2026. Developers should start planning their migration now. That means either subscribing to Etherscan's Pro tier or finding another data source. The affected users include dApp developers, data analysts, and anyone who relies on the free API for Gnosis Chain queries.
It's unclear whether Etherscan will offer a discounted rate for existing Gnosis Chain users or provide any grace period. The company hasn't responded to requests for comment.
