If you’ve ever used Etherscan to check a transaction, verify a contract, or build a dApp that pulls on-chain data, you’ve relied on infrastructure that most people treat like tap water: always available, always free. That assumption is starting to crack.
Etherscan has moved Gnosis Chain out of its free API tier, pushing developers who need full indexing and API functionality toward paid plans. And by August 11, 2026, the dedicated Gnosisscan platform itself faces deprecation, meaning the shift to Pro-tier access isn’t a temporary inconvenience. It’s the new default.
What changed and why it matters
As of November 22, 2025, Etherscan reduced its free API tier coverage to roughly 90% of previously supported chains. The reason is straightforward: higher transaction speeds, growing TPS rates, and sheer transaction volume across networks have pushed operational costs to a point where free universal coverage is no longer sustainable.
Gnosis Chain, identified as chain ID 100, is one of the networks that fell outside that 90% cutoff. Developers and applications that previously queried Gnosis data through Etherscan’s free endpoints now need to upgrade to a paid tier for continued access.
Verified contract endpoints, including source code and ABI data, remain free across all chains, Gnosis included. But if your application relies on transaction history, token transfers, event logs, or any of the heavier indexing work, that’s now behind a paywall.
To soften the blow, Etherscan introduced a new Lite plan priced at approximately 25% of the cost of its previous lowest paid tier.
The Gnosisscan deprecation timeline
Etherscan plans to deprecate Gnosisscan entirely on August 11, 2026. After that date, any remaining free-tier access points specific to Gnosis will redirect users toward Pro-tier subscriptions.
This creates a clear decision point for any project built on Gnosis Chain. Either budget for Etherscan’s paid plans, or migrate to an alternative indexer before the deadline arrives.
Alternatives and the competitive landscape
Blockscout, an open-source blockchain explorer, has been positioning itself as an alternative for multichain indexing. It already supports a wide range of EVM-compatible networks, and the Gnosis community has historically maintained its own Blockscout instance.
What this means for developers and investors
For developers, the immediate action item is auditing any application that calls Etherscan’s API for Gnosis Chain data. If your dApp, dashboard, or analytics tool relies on those endpoints, you need to either subscribe to the Lite or Pro plan, or begin integrating with an alternative indexer like Blockscout before the deprecation deadline.
The Lite plan at 25% of the prior lowest tier’s cost offers a middle ground, but teams should evaluate whether that tier includes the specific endpoints and rate limits their applications require.
