CallResult<ErrorType>: object

Result of a TEVM VM Call method.

Example

import { createClient } from 'viem'
import { createTevmTransport, tevmCall } from 'tevm'
import { optimism } from 'tevm/common'
import { CallResult } from 'tevm/actions'


const client = createClient({
  transport: createTevmTransport({}),
  chain: optimism,
})


const callParams = {
  data: '0x...',
  bytecode: '0x...',
  gasLimit: 420n,
}


const result: CallResult = await tevmCall(client, callParams)
console.log(result)

Type Parameters

• ErrorType = TevmCallError

Type declaration

accessList?

optional accessList: Record<Address, Set<Hex>>

The access list if enabled on call. Mapping of addresses to storage slots.

Example

const accessList = result.accessList
console.log(accessList) // { "0x...": Set(["0x..."]) }

amountSpent?

optional amountSpent: bigint

The amount of ether used by this transaction. Does not include L1 fees.

baseFee?

optional baseFee: bigint

The base fee of the transaction.

blobGasUsed?

optional blobGasUsed: bigint

Amount of blob gas consumed by the transaction.

createdAddress?

optional createdAddress: Address

Address of created account during the transaction, if any.

createdAddresses?

optional createdAddresses: Set<Address>

Map of addresses which were created (used in EIP 6780). Note the addresses are not actually created until the transaction is mined.

errors?

optional errors: ErrorType[]

Description of the exception, if any occurred.

executionGasUsed

executionGasUsed: bigint

Amount of gas the code used to run within the EVM. This only includes gas spent on the EVM execution itself and doesn’t account for gas spent on other factors such as data storage.

gas?

optional gas: bigint

Amount of gas left after execution.

gasRefund?

optional gasRefund: bigint

The gas refund counter as a uint256.

l1BaseFee?

optional l1BaseFee: bigint

Latest known L1 base fee known by the L2 chain. Only included when an OP-Stack common is provided.

See

OP-Stack docs

l1BlobFee?

optional l1BlobFee: bigint

Current blob base fee known by the L2 chain.

See

OP-Stack docs

l1Fee?

optional l1Fee: bigint

L1 fee that should be paid for the transaction. Only included when an OP-Stack common is provided.

See

OP-Stack docs

l1GasUsed?

optional l1GasUsed: bigint

Amount of L1 gas used to publish the transaction. Only included when an OP-Stack common is provided.

See

OP-Stack docs

logs?

optional logs: Log[]

Array of logs that the contract emitted.

Example

const logs = result.logs
logs?.forEach(log => console.log(log))

minerValue?

optional minerValue: bigint

The value that accrues to the miner by this transaction.

preimages?

optional preimages: Record<Hex, Hex>

Preimages mapping of the touched accounts from the transaction (see reportPreimages option).

priorityFee?

optional priorityFee: bigint

Priority fee set by the transaction.

rawData

rawData: Hex

Encoded return value from the contract as a hex string.

Example

const rawData = result.rawData
console.log(`Raw data returned: ${rawData}`)

selfdestruct?

optional selfdestruct: Set<Address>

A set of accounts to selfdestruct.

totalGasSpent?

optional totalGasSpent: bigint

The amount of gas used in this transaction, which is paid for. This contains the gas units that have been used on execution, plus the upfront cost, which consists of calldata cost, intrinsic cost, and optionally the access list costs. This is analogous to what eth_estimateGas would return. Does not include L1 fees.

trace?

optional trace: DebugTraceCallResult

The call trace if tracing is enabled on call.

Example

const trace = result.trace
trace.structLogs.forEach(console.log)

txHash?

optional txHash: Hex

The returned transaction hash if the call was included in the chain. Will not be defined if the call was not included in the chain. Whether a call is included in the chain depends on the createTransaction option and the result of the call.

Example

const txHash = result.txHash
if (txHash) {
  console.log(`Transaction included in the chain with hash: ${txHash}`)
}
