# AbiConstructor.encode

ABI-encodes the provided constructor input (`inputs`).

## Imports

:::code-group
```ts [Named]
import { AbiConstructor } from 'ox'
```

```ts [Entrypoint]
import * as AbiConstructor from 'ox/AbiConstructor'
```
:::

## Examples

```ts twoslash
import { AbiConstructor } from 'ox'

const constructor = AbiConstructor.from(
  'constructor(address, uint256)'
)

const data = AbiConstructor.encode(constructor, {
  bytecode: '0x...',
  args: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045', 123n]
})
```

### ABI-shorthand

You can also specify an entire ABI object as a parameter to `AbiConstructor.encode`.

```ts twoslash
// @noErrors
import { Abi, AbiConstructor } from 'ox'

const abi = Abi.from([...])

const data = AbiConstructor.encode(abi, { // [!code focus]
  bytecode: '0x...', // [!code focus]
  args: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045', 123n], // [!code focus]
}) // [!code focus]
```

### End-to-end

Below is an end-to-end example of using `AbiConstructor.encode` to encode the constructor of a contract and deploy it.

```ts twoslash
import 'ox/window'
import { AbiConstructor, Hex } from 'ox'

// 1. Instantiate the ABI Constructor.
const constructor = AbiConstructor.from(
  'constructor(address owner, uint256 amount)'
)

// 2. Encode the ABI Constructor.
const data = AbiConstructor.encode(constructor, {
  bytecode: '0x...',
  args: ['0xd8da6bf26964af9d7eed9e03e53415d37aa96045', 123n]
})

// 3. Deploy the contract.
const hash = await window.ethereum!.request({
  method: 'eth_sendTransaction',
  params: [{ data }]
})
```

:::note
For simplicity, the above example uses `window.ethereum.request`, but you can use any type of JSON-RPC interface.
