# Cross-Chain Access

**Overview**

ASK is deployed as an **OFT (Omnichain Fungible Token)** via [LayerZero](https://layerzeroscan.com/oft/ASK/Permission), the leading cross-chain interoperability protocol. This architecture allows ASK to move natively across supported blockchain networks without wrapping or re-minting, preserving a single unified token supply across all chains.

ASK is currently live on **Base** and **Polygon**, with additional EVM-compatible networks planned in step with ecosystem demand.

**Why LayerZero**

LayerZero enables ASK to be truly omnichain by providing:

* **Native cross-chain movement** — ASK moves between supported networks without asset swaps, wrapping, or re-minting
* **Unified supply** — Token supply remains consistent across all chains at all times
* **Decentralized security** — Lightweight messaging architecture with no central point of failure
* **Scalability** — ASK can expand to additional networks with minimal friction as the ecosystem grows
* **On-chain transparency** — Every permission and reward interaction is immutably recorded and auditable

**Supported Networks**

| Network | Status   | Contract Address                             |
| ------- | -------- | -------------------------------------------- |
| Base    | ✅ Active | `0xBB146326778227A8498b105a18f84E0987A684b4` |
| Polygon | ✅ Active | `0xaA3717090CDDc9B227e49d0D84A28aC0a996e6Ff` |

Always confirm you are using the official contract address before interacting with ASK on any network. See [Contract Addresses](https://docs.permission.ai/ask-token/contract-addresses) for full details.

**Compatible Wallets and Applications**

ASK is EVM-compatible and works with most standard Ethereum wallets. Confirmed compatible platforms include:

* **Coinbase Wallet**
* **MetaMask**
* **Stargate** (bridging)
* **Aerodrome Finance** (DEX on Base)

**Moving ASK Between Networks**

ASK can be bridged between Base and Polygon via **Stargate**, powered by LayerZero infrastructure.

For step-by-step bridging instructions, see How to Bridge ASK.

**A Note for Holders of Legacy Wormhole-Bridged ASK**

Prior to the LayerZero integration, some users bridged ASK to Base via Wormhole. That wrapped token contract (`0x79322CEE6C90735b967d2396b9ADc392915aeBB6`) has been deprecated and is no longer supported.

If you still hold Wormhole-bridged ASK, see How to Bridge ASK for migration instructions, or contact <support@permission.ai> for assistance.

**Security Reminders**

* **Always verify contract addresses** before interacting with ASK on any network
* Permission will never DM you asking for wallet credentials or private keys
* Use only official Permission channels for support: <support@permission.ai>
