Explorer: adding a network
Reviewed September 6, 2026.
The Signet explorer and the related Open Explorer variant have different supported behaviors. The first includes protocol-specific discovery and action flows. The configurable variant documents OP Stack testnet support.
Configuration to inspect
Start with the chain ID, native currency, RPC and explorer endpoints in src/lib/chains.ts. Check the canonical token registry separately. Confirm the data expected from Blockscout rather than assuming every explorer API has the same contract.
Verify before exposing actions
Requests and caches must be scoped to the selected network. Wallet actions also need matching chain requirements. The inspected Open Explorer README disables protocol actions and builder, filler and order telemetry until a network’s data contract is verified.
A network selector alone does not establish support for an arbitrary chain.
Revision context
The public Signet artifact identified Gouda when reviewed on September 6, 2026. The local README still named Parmigiana. Align the deployed revision before using the article as a reproducible transaction guide.
