# Robinhood Chain methods

> Complete reference of Robinhood Chain JSON-RPC methods supported on Chainstack, with per-method availability for the eth, debug, net, web3, and arb namespaces. Live-tested against Chainstack Robinhood Chain nodes.

Our pricing is simple: 1 RU per full request, 2 RUs per archive. For which EVM methods are full vs archive, see [Request units — EVM methods affected by block age](/docs/request-units#evm-methods-affected-by-block-age).

See also [interactive Robinhood Chain API call examples](/reference/robinhood-getting-started).

Robinhood Chain runs the Arbitrum Nitro client. The availability below is verified against Chainstack Robinhood Chain nodes. All standard Geth `debug_*` tracers — `callTracer`, `flatCallTracer`, `prestateTracer`, `4byteTracer`, and the struct/opcode logger — are supported on `debug_traceTransaction`, `debug_traceBlockByNumber`, `debug_traceBlockByHash`, and `debug_traceCall`. The Parity-style `arbtrace_*` and `trace_*` namespaces are not exposed — use the `debug_*` tracers instead.
