# ContractAddress

Utility functions for computing Contract Addresses.

## Examples

Below are some examples demonstrating common usages of the `ContractAddress` module:

* [Computing Contract Addresses (CREATE)](#computing-contract-addresses-\(create\))

* [Computing Contract Addresses (CREATE2)](#computing-contract-addresses-\(create2\))

### Computing Contract Addresses (CREATE)

A Contract Address that was instantiated using the `CREATE` opcode can be computed using [`ContractAddress.fromCreate`](/api/ContractAddress/fromCreate):

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

ContractAddress.fromCreate({
  from: '0x1a1e021a302c237453d3d45c7b82b19ceeb7e2e6',
  nonce: 0n
})
// @log: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2'
```

### Computing Contract Addresses (CREATE2)

A Contract Address that was instantiated using the `CREATE2` opcode can be computed using [`ContractAddress.fromCreate2`](/api/ContractAddress/fromCreate2):

```ts twoslash
import { Bytes, ContractAddress, Hex } from 'ox'

ContractAddress.fromCreate2({
  from: '0x1a1e021a302c237453d3d45c7b82b19ceeb7e2e6',
  bytecode: Bytes.from(
    '0x6394198df16000526103ff60206004601c335afa6040516060f3'
  ),
  salt: Hex.fromString('hello world')
})
// @log: '0x59fbB593ABe27Cb193b6ee5C5DC7bbde312290aB'
```
