debug_traceCall - Manta RPC Method
Trace a call without executing on Manta Pacific. Requires archive node for debugging ZK-enabled DeFi, private identity verification, and modular ZK applications via Universal Circuits.
Traces a call without creating a transaction on Manta Pacific.
Archive Node Required
This method requires an archive node. It is not available on full nodes.
Use Cases
- Transaction simulation - Debug before sending
- Gas analysis - Analyze gas usage per opcode
- Contract debugging - Step through execution for ZK-enabled DeFi, private identity verification, and modular ZK applications via Universal Circuits
Request Parameters
Call object (same as eth_call)
Block number or tag
Tracer configuration
