CallParams

CallParams<TThrowOnFail>: BaseCallParams<TThrowOnFail> & object

TEVM parameters to execute a call on the VM. Call is the lowest level method to interact with the VM, and other methods such as contract and script use call under the hood.

Type declaration

code?

readonly optional code: Hex

The encoded code to deploy with for a deployless call. Code is encoded with constructor arguments, unlike deployedBytecode.

Examples

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

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

const callParams = {
  createTransaction: true,
  data: encodeDeployData({
    bytecode: '0x...',
    data: '0x...',
    abi: [{...}],
    args: [1, 2, 3],
  })
}

await tevmCall(client, callParams)

Code is also automatically created if using TEVM contracts via the script method.

import { createClient } from 'viem'
import { createTevmTransport, tevmContract } from 'tevm'
import { optimism } from 'tevm/common'
import { SimpleContract } from 'tevm/contracts'

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

const script = SimpleContract.script({ constructorArgs: [420n] })

await tevmContract(client, script.read.get()) // 420n

data?

readonly optional data: Hex

The input data for the call.

deployedBytecode?

readonly optional deployedBytecode: Hex

The code to put into the state before executing the call. If you wish to call the constructor, use code instead.

Example

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

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

const callParams = {
  data: '0x...',
  deployedBytecode: '0x...',
}

await tevmCall(client, callParams)

salt?

readonly optional salt: Hex

An optional CREATE2 salt.

Example

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

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

const callParams = {
  data: '0x...',
  bytecode: '0x...',
  gasLimit: 420n,
  salt: '0x1234...',
}

await tevmCall(client, callParams)
