debug_* and trace_*

The debug_* and trace_* namespaces give you opcode-level visibility into transaction execution. They’re used by block explorers, security tools, MEV searchers, and indexers that need internal-call data. Both namespaces are served from https://rpc.goldrushdata.com/v1/{chain}.

Looking for a wallet’s internal transaction history? These methods are per-transaction and per-block primitives, not a wallet-history endpoint. Reconstructing one address’s internal transfers from raw traces means scanning a block range twice with trace_filter (once by fromAddress, once by toAddress) - and on chains where trace_filter isn’t available (e.g. OP-stack L2s) falling back to debug_traceBlockByNumber block-by-block. For decoded, wallet-level internal transfers across chains with no client-side call-tree walking, use the Foundational API’s with-internal param instead.

debug_* methods (Geth-style)

Method	Summary	Rate
`debug_traceTransaction`	Step-by-step EVM trace of a mined transaction.	0.015
`debug_traceCall`	Trace an `eth_call` without producing a transaction.	0.015
`debug_traceBlockByHash`	Trace every transaction in a block (by hash).	0.015
`debug_traceBlockByNumber`	Trace every transaction in a block (by number).	0.015

All four accept a tracer config:

{
  "tracer": "callTracer",
  "tracerConfig": { "withLog": true },
  "timeout": "30s"
}

Common tracer values: callTracer (call graph), prestateTracer (state diff), 4byteTracer (4-byte selector frequency), or omit for the default opcode-level trace.

trace_* methods (Parity-style)

Method	Summary	Rate
`trace_transaction`	Parity trace of a mined transaction.	0.015
`trace_block`	Parity traces of every transaction in a block.	0.015
`trace_filter`	Parity traces matching a filter (sender, recipient, range).	0.015
`trace_call`	Parity trace of an `eth_call`.	0.015
`trace_callMany`	Parity traces for a sequence of calls executed in order.	0.015
`trace_rawTransaction`	Parity trace of a signed, unmined raw transaction.	0.015
`trace_replayTransaction`	Replay a mined transaction and return traces, vmTrace, and state diff.	0.015
`trace_replayBlockTransactions`	Replay every transaction in a block with selectable trace outputs.	0.015
`trace_get`	Fetch a specific sub-trace from a mined transaction by index path.	0.015

trace_* is the canonical Erigon/Parity format. Prefer it when integrating with tooling that expects Erigon traces (e.g. block-explorer pipelines).

Per-chain availability

Trace and debug support depends on what the upstream node software exposes. Erigon and Reth both expose trace_* natively, while Geth-based upstreams expose debug_*. GoldRush surfaces whichever is available, and falls back to a normalized translation where one namespace is missing.

Chain	`debug_*`	`trace_*`	Archive depth
Ethereum (`eth-mainnet`)	✅	✅	Genesis
Polygon (`matic-mainnet`)	✅	✅	Genesis
BNB Smart Chain (`bsc-mainnet`)	✅	✅	Genesis
Arbitrum (`arbitrum-mainnet`)	✅	✅	Nitro genesis
Base (`base-mainnet`)	✅	✅	Genesis
HyperEVM (`hyperevm-mainnet`)	✅	✅	Genesis
MegaETH (`megaeth-mainnet`)	⚠️ rolling	⚠️ rolling	Last 30 days
Monad (`monad-mainnet`)	⚠️ rolling	⚠️ rolling	Last 30 days
Tempo (`tempo-mainnet`)	⚠️ rolling	⚠️ rolling	Last 7 days

⚠️ “Rolling” means the upstream archive window slides forward over time. For deeper history on these chains, contact GoldRush support to discuss dedicated archive nodes.

Solana

Solana does not expose the debug_* or trace_* namespaces; they are EVM-specific. For transaction introspection on Solana, use:

Goal	Solana method
Inspect a confirmed transaction’s logs, balances, and compute units	`getTransaction`
Dry-run a transaction and read its logs and state changes before sending	`simulateTransaction`
Stream logs for a program or account in real time	`logsSubscribe`

simulateTransaction is the closest analogue to debug_traceCall / trace_call: it returns the program logs, the error (if any), compute units consumed, and optionally post-simulation account state, without broadcasting the transaction.

debug_* and trace_* are heavier than standard eth_* reads. See pricing for full rates.
