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.

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,
}

await tevmCall(client, callParams)

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)
