Object
- The transaction call object with the following:
from
(optional): the address the transaction is sent from.
to
(required): the address the transaction is sent to.
gas
(optional): Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
gasPrice
(optional): Integer of the gasPrice used for each paid gas.
value
(optional): Integer of the value sent with this transaction.
data
(optional): Hash of the method signature and encoded parameters. For details see .
Quantity
or tag
- choose 1 of the following options:
A hexadecimal block number.
"earliest"
- the earliest/genesis block.
"latest"
- the latest mined block.
"finalized"
- the latest finalized block.
"pending"
- the pending state/transactions.
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.
