# How to Bridge ASK
## **Overview**
ASK is an **OFT (Omnichain Fungible Token)** powered by LayerZero, currently live on both **Base** and **Polygon**. You can move ASK between these networks using **Stargate**, LayerZero's official bridging interface.
⚠️ **Important:** Always verify contract addresses before initiating any bridge transaction. See [Contract Addresses](https://docs.permission.ai/ask-token/contract-addresses) for official details.

⚠️ **Important:** The bridging instructions on this page are provided for informational purposes only. Bridging transactions are executed directly on third-party protocols (Stargate, LayerZero, Portal Bridge) and are not controlled by Permission. Permission is not responsible for failed transactions, lost funds, delays, or errors arising from user error, wallet misconfiguration, network congestion, or third-party platform issues. Blockchain transactions are irreversible. Always verify contract addresses and transaction details carefully before confirming. When in doubt, contact before proceeding.
#### **Bridging ASK from Polygon to Base**
**Prerequisites:**
* A compatible EVM wallet (MetaMask, Coinbase Wallet, etc.)
* ASK tokens on Polygon
* MATIC (POL) on Polygon for gas fees
**Steps:**
1. Visit [Stargate Finance](https://stargate.finance/bridge) and connect your wallet
2. Select **Polygon** as the source chain and **Base** as the destination chain
3. Select ASK as the token and enter the amount to bridge
4. Confirm the contract address on Base is `0xBB146326778227A8498b105a18f84E0987A684b4`
5. Review the transaction details and confirm in your wallet
6. Wait for the transaction to complete — bridging typically takes a few minutes
#### **Bridging ASK from Base to Polygon**
**Prerequisites:**
* A compatible EVM wallet
* ASK tokens on Base
* ETH on Base for gas fees
**Steps:**
1. Visit [Stargate Finance](https://stargate.finance/bridge) and connect your wallet
2. Select **Base** as the source chain and **Polygon** as the destination chain
3. Select ASK as the token and enter the amount to bridge
4. Confirm the contract address on Base is `0xBB146326778227A8498b105a18f84E0987A684b4`
5. Review the transaction details and confirm in your wallet
6. Wait for the transaction to complete
#### **Legacy Wormhole Migration**
Prior to the LayerZero integration, some users bridged ASK to Base via Wormhole. That wrapped token contract has been deprecated and is no longer supported or tradable.
**Deprecated contract (do not use):** `0x79322CEE6C90735b967d2396b9ADc392915aeBB6`
If you still hold Wormhole-bridged ASK, follow these steps to migrate:
**Step 1 — Bridge from Base back to Polygon via Wormhole**
1. Visit [Portal Bridge](https://portalbridge.com) and connect your wallet
2. Ensure you have ETH on Base for gas fees
3. Select **Base** as the source chain and **Polygon** as the destination
4. Enter the deprecated contract address: `0x79322CEE6C90735b967d2396b9ADc392915aeBB6`
5. Bridge your ASK back to Polygon and confirm in your wallet
**Step 2 — Bridge from Polygon to Base via Stargate**
1. Follow the Polygon to Base bridging steps above
2. Confirm you are using the current Base contract address: `0xBB146326778227A8498b105a18f84E0987A684b4`
**Security Reminders**
* **Never use the deprecated Wormhole contract address** for new transactions
* **Always verify contract addresses** against the official list in [Contract Addresses](https://docs.permission.ai/ask-token/contract-addresses) before bridging
* Permission will never DM you with bridging instructions or ask for your private key
* If you need help, contact
