JSON-RPC

Method matrix

Generated from probes against production Arc nodes, not copied from an Ethereum reference. Last run 2026-09-16 04:00 UTC.

Four states. Live returns data. Returns null means the client registers the method but answers null, which fails quietly and is worse than an error. Blocked by Arc means the protocol refuses it. Not exposed means we do not serve the namespace, following Arc operator guidance for public nodes.

Restricted namespaces

admin_* and ots_* are not exposed on any ArcRPC endpoint. Arc operator guidance restricts a public relay to eth, net, web3 and rpc; we serve debug, trace and txpool from our own authenticated pools rather than from a public relay, which is why they are available here and absent from the network public endpoint.
