Parameters

​
chainId
string
default:"137"
required
Unique identifier for a blockchain network.
​
id
number
default:1
required
Request identifier used to match responses.
​
jsonrpc
string
default:"2.0"
required
JSON-RPC version.
​
method
string
default:"debug_traceCallMany"
required
JSON-RPC method name.
​
params
object
required
Parameters for debug_traceCallMany. 1. Bundles (required): an array of bundles. Each bundle is an object with: - transactions: an array of transaction objects (each with fields such as from, to, value, data), - blockOverride (optional): an object with overrides (blockNumber, blockHash mapping, coinbase, timestamp, difficulty, gasLimit, baseFee). 2. Simulation context (required): an object with blockIdentifier (a hex block number or one of “latest”, “earliest”, “pending”, “safe”, “finalized”) and transactionIndex (integer, default -1). 3. State overrides (optional): an object mapping addresses to state override objects (here, at least a balance override as a hex string). 4. Timeout (optional): integer timeout in milliseconds (default 5000). 5. Trace type (optional): an object with tracer (string, enum: callTracer, prestateTracer), tracerConfig (object), and onlyTopCall (boolean).Positional parameters for debug_traceCallMany:
  • params[0]: List of bundles. Each bundle is an object with transactions and an optional blockOverride.
  • params[1]: Simulation context. Contains blockIdentifier (a hex block number or tag) and transactionIndex (default -1).
  • params[2]: Optional state overrides: a mapping from address to an override object (e.g. balance).
  • params[3]: Simulation timeout in milliseconds.
  • params[4]: Tracer configuration (optional). Contains tracer type, optional tracerConfig, and onlyTopCall flag.

​
Returns

​
result
array
Array of trace responses corresponding to each simulated bundle. Each trace response is one of: callTracer response, prestateTracer response, or opcode (struct) response.
