Documentation

Build on Arc without relearning Arc.

Standard EVM tooling works unchanged. These pages cover what is not standard: two USDC decimal interfaces, a closed mempool, deterministic finality, the arc_* namespace and a base fee floor that drops transactions silently.

Start with the quickstart for an endpoint in two minutes. Read the Arc differences page before shipping anything that moves money. The method matrix is regenerated from probes against production nodes every six hours, last run 2026-09-16 04:00 UTC.

JSON-RPC

Arc-native APIs

Realtime and tooling

Nothing here is required to use the service. Every feature is reachable over plain JSON-RPC and REST, and the SDKs only wrap what the endpoint already returns. If a page contradicts the endpoint, the endpoint is right and the page is a bug: tell us.
