# AccountConfig

Configurable account configuration utilities (TIP-1107).

Configurable accounts have weighted owners and an approval threshold that
can change without changing the account address. Derives the stable account
address from the initial configuration, computes configuration commitments,
and computes the owner approval digest that owners sign.

## Examples

```ts twoslash
import { AccountConfig } from 'ox/tempo'

const initialConfig = AccountConfig.from({
  threshold: 2,
  owners: [
    {
      owner: '0x1111111111111111111111111111111111111111',
      weight: 1
    },
    {
      owner: '0x2222222222222222222222222222222222222222',
      weight: 1
    }
  ]
})

const account = AccountConfig.getAddress(initialConfig, {
  factory: '0x7171717171717171717171717171717171717171'
})
```
