contractHandler

contractHandler(client, options?): ContractHandler

Creates a tree-shakable instance of contractHandler for handling contract interactions with the Ethereumjs EVM. This function uses callHandler under the hood to execute contract calls.

Note: This is the internal logic used by higher-level APIs such as tevmContract.

Parameters

• client: TevmNode<"fork" | "normal", object>

The TEVM base client instance.

• options? = {}

Optional parameters.

• options.throwOnFail?: undefined | boolean = true

Whether to throw an error on failure.

Returns

ContractHandler

The contract handler function.

Throws

If throwOnFail is true, returns TevmCallError as value.

Example

import { createTevmNode } from 'tevm/node'
import { contractHandler } from 'tevm/actions'

const client = createTevmNode()

const contract = contractHandler(client)

const res = await contract({
  to: `0x${'69'.repeat(20)}`,
  abi: [{...}], // ABI array
  functionName: 'myFunction',
  args: [1, 2, 3],
})
