tevmCall

tevmCall(client, params): Promise<CallResult<TevmCallError>>

A tree-shakeable version of the tevmCall action for viem. Executes a call against the VM. It is similar to eth_call but provides more options for controlling the execution environment.

By default, it does not modify the state after the call is complete, but this can be configured with the createTransaction option.

Parameters

• client: Client<TevmTransport<string>, undefined | Chain, undefined | Account, undefined, undefined | object>

The viem client configured with TEVM transport.

• params: CallParams<boolean>

Parameters for the call, including the target address, call data, sender address, gas limit, gas price, and other options.

Returns

Promise<CallResult<TevmCallError>>

The result of the call.

Example

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

const client = createClient({
  transport: createTevmTransport({
    fork: { transport: http('https://mainnet.optimism.io')({}) }
  }),
  chain: optimism,
})

async function example() {
  const res = await tevmCall(client, {
    to: '0x123...',
    data: '0x123...',
    from: '0x123...',
    gas: 1000000,
    gasPrice: 1n,
    skipBalance: true,
  })
  console.log(res)
}
