# xAnchor Core

The xAnchor Core contract receives messages from the foreign chain (via the xAnchor Bridge), and forwards them to the AddressProxy contract. If needed, it will initialize a copy of the AddressProxy contract for any foreign address that doesn’t have a corresponding proxy contract already deployed.

### Config

| ----------------------- | -------- | ------------------------------------------------------- |
| `address_proxy_code_id` | `u64`    | The cosmwasm Code ID of the Address Proxy contract WASM |
| `owner`                 | `String` | Address of contract owner                               |
| `overseer_address`      | `String` | Address of Anchor Overseer Contract                     |
| `anc_gov_address`       | `String` | Address of Anchor Governance Contract                   |
