ContractCallLocal

ContractCallLocalQuery

Call a function of the given smart contract instance, giving it functionParameters as its inputs. It will consume the entire given amount of gas.

Field
Type
Description

header

Standard info sent from client to node, including the signed payment, and what kind of response is requested (cost, state proof, both, or neither). The payment must cover the fees and all of the gas offered.

contractID

The contract to make a static call against

gas

int64

The amount of gas to use for the call. All of the gas offered will be charged for.

functionParameters

bytes

Which function to call, and the parameters to pass to the function

maxResultSize

int64

Max number of bytes that the result might include. The run will fail if it would have returned more than this number of bytes. [deprecated 0.20.0]

ContractCallLocalResponse

Response when the client sends the node ContractCallLocalQuery

Field
Type
Description

header

standard response from node to client, including the requested fields: cost, or state proof, or both, or neither

functionResult

ContractFunctionResult

the value returned by the function (if it completed and didn't fail)

ContractFunctionResult

The result returned by a call to a smart contract function. This is part of the response to a ContractCallLocal query, and is in the record for a ContractCall or ContractCreateInstance transaction. The ContractCreateInstance transaction record has the results of the call to the constructor.

Field
Type
Description

contractID

The smart contract instance whose function was called

contractCallResult

bytes

The result returned by the function

errorMessage

string

The message in case there was an error during smart contract execution

bloom

bytes

Bloom filter for record

gasUsed

uint64

Units of gas used to execute contract

logInfo

The log info for events returned by the function

createdContractIDs

The list of smart contracts that were created by the function call [deprecated]

stateChanges

The list of state reads and changes caused by this function call

evm_address

bytes

gas

int64

The amount of gas available for the call, aka the gasLimit. This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.

amount

int64

Number of tinybars sent (the function must be payable if this is nonzero). This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.

functionParameters

bytes

The parameters passed into the contract call. This field should only be populated when the paired TransactionBody in the record stream is not a ContractCreateTransactionBody or a ContractCallTransactionBody.

signerNonce

int64

The value of the signer account nonce. This value can be null.

ContractLoginfo

The log information for an event returned by a smart contract function call. One function call may return several such events.

Field
Type
Description

contractID

Address of a contract that emitted the event

bloom

bytes

Bloom filter for a particular log

topic

repeated bytes

Topics of a particular event

data

bytes

Event data

ContractStateChange

The storage changes to a smart contract's storage as a side effect of the function call.

Field
Type
Description

contractID

The contract to which the storage changes apply to

storageChanges

The list of storage changes

StorageChange

A storage slot change description.

Field
Type
Description

slot

bytes

The storage slot changed. Up to 32 bytes, big-endian, zero bytes left trimmed

valueRead

bytes

The value read from the storage slot. Up to 32 bytes, big-endian, zero bytes left trimmed. Because of the way SSTORE operations are charged the slot is always read before being written to

valueWritten

google.protobuf.BytesValue

The new value written to the slot. Up to 32 bytes, big-endian, zero bytes left trimmed. If a value of zero is written the valueWritten will be present but the inner value will be absent. If a value was read and not written this value will not be present.

repeated

repeated

The 20-byte EVM address of the contract to call. Only populated after release 0.23, where each created contract will have its own record. There will be seperate chld record for each created contract. Every contract has an EVM address determined by its shard.realm.num id. This address is as follows: The first 4 bytes are the big-endian representation of the shard. The next 8 bytes are the big-endian representation of the realm. The final 8 bytes are the big-endian representation of the number. Contracts created via CREATE2 have an additional, primary address that is derived from the specification, and does not have a simple relation to a shard.realm.num id. (Please do note that CREATE2 contracts can also be referenced by the three-part EVM address described above.)
