# 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.

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 applies to Robinhood Chain Mainnet and Testnet on Global Nodes. The default native tracers — `callTracer`, `prestateTracer`, `4byteTracer`, and `noopTracer` — and the struct/opcode logger are supported on [`debug_traceTransaction`](/reference/robinhood-debug-tracetransaction), [`debug_traceBlockByNumber`](/reference/robinhood-debug-traceblockbynumber), [`debug_traceBlockByHash`](/reference/robinhood-debug-traceblockbyhash), and [`debug_traceCall`](/reference/robinhood-debug-tracecall). `flatCallTracer`, `muxTracer`, and `erc7562Tracer` are not enabled — see [Available native tracers](/docs/limits#available-native-tracers). The Parity-style `arbtrace_*` and `trace_*` namespaces are not exposed — use the `debug_*` tracers instead.
