Blockhash - the hash of the block to be traced.
Tracer - choose from one of these options:
4byteTracer - Solidity contract functions are using the first four byte of the Keccak-256 hash of their signature. This tracer monitors and analyzes the usage of specific function signatures within smart contracts by capturing their unique first four bytes.
callTracer - collects data about all call frames executed within a transaction, creating a hierarchical list of call frames structured mirroring the EVM's operations. This is useful for debugging and analytical purposes.
prestateTracer - captures and analyzes the state of the blockchain before the execution of a specific transaction. It helps in understanding the state changes and effects that a transaction will have on the blockchain's data and accounts before the transaction is actually executed.
noopTracer - returns empty results. This is used for testing purpose.
opcountTracer - count and track the number of operations (or opcodes) executed during a specific transaction.
unigramTracer - counts the frequency of occurrence of each opcode.
bigramTracer - a bigram refers to a sequence of two bytes or characters. This tracer is designed to observe and provide insights into the patterns and occurrences of these two-byte sequences as they appear within the data of executed transactions.
trigramTracer - a trigram refers to a sequence of three bytes or characters. This tracer is designed to observe and provide insights into the patterns and occurrences of these three-byte sequences as they appear within the data of executed transactions.
evmdisTracer - generates the bytecode disassembly of executed transactions, providing developers with insights into how smart contracts operate at a low-level bytecode level for debugging, security audits, and performance optimization purposes.
