rpc_modules - Gnosis RPC Method
Inspect which JSON-RPC namespaces are enabled on your Gnosis endpoint. Useful for capability checks, client diagnostics, and RPC feature discovery.
Returns the enabled JSON-RPC namespaces exposed by the connected Gnosis endpoint together with their version strings.
Non-standard method.
rpc_modulesis a client-introspection RPC that is commonly available on Geth-compatible stacks, but it is not part of the core Ethereum Execution API method set. Availability varies by client and operator policy.
Why Gnosis? Build on the prediction market pioneer with $260M+ TVL and xDAI stablecoin-based gas fees with stablecoin gas fees for predictable costs, Shutter MEV protection, 150K+ Safe wallets, and Circles decentralized UBI protocol.
When to Use This Method
rpc_modules is useful for prediction market builders, DAO tooling developers, and teams building MEV-protected applications:
- Capability Discovery — Detect whether namespaces like
debug,trace,txpool, orerigonare exposed before attempting those calls - Client Diagnostics — Verify what the serving node has enabled when debugging environment-specific issues
- Infrastructure Audits — Compare public and private endpoints to confirm which RPC surfaces are intentionally exposed
- Runtime Feature Gating — Adjust tooling behavior dynamically based on the actual namespaces available on a node
Request Parameters
This method accepts no parameters.
Response Body
Object whose keys are enabled namespaces and whose values are version strings
