# Bridge

**Bridge** is a cross-chain asset bridging tool provided by the TaskOn platform, designed to help users transfer tokens across multiple blockchains. Its goal is to enable users to quickly move their assets to the correct chain when participating in tasks, airdrops, or OnChain interactions.

#### 1. Functional Positioning

* **Cross-Chain Transfers**: Transfer tokens from Chain A to Chain B (e.g., Ethereum → BNB Chain).
* **Multi-Chain Support**: Supports major chains such as Ethereum, BNB Chain, Arbitrum, Optimism, Polygon, Base, and more.
* **Facilitate Task Interactions**: Many TaskOn tasks require interactions on a specific chain. If your wallet lacks tokens on that chain, you can use Bridge to quickly transfer them.

#### 2. Preparation Before Use

1. **Install a Wallet**
   * Recommended wallets such as \[MetaMask] or \[OKX Wallet] that support multiple chains.
2. **Prepare Tokens**
   * Ensure you have sufficient tokens (e.g., ETH, USDT) in your source chain (From chain) wallet.
   * You will also need a small amount of the source chain’s native token (e.g., ETH, BNB) to cover Gas fees.

#### 3. Operational Workflow

1. **Access the Bridge Page**
   * Find the Bridge entry on the TaskOn homepage or navigation bar.
2. **Select Cross-Chain Direction**
   * Configure the following in the interface:
     * **From**: Select the chain you want to transfer from (e.g., Ethereum).
     * **To**: Select the target chain (e.g., Arbitrum).
3. **Choose Token and Amount**
   * Click the Token dropdown menu to select the token you want to transfer (e.g., USDT, ETH).
   * Enter the transfer amount.
4. **Confirm the Transaction**
   * Click "Connect Wallet" to connect your wallet.
   * Click "Swap."
   * A transaction confirmation window will pop up. Click "Confirm."
5. **Wait for Cross-Chain Completion**
   * The cross-chain transfer may take some time (typically a few minutes, depending on the network and bridging protocol).
   * Once completed, you will receive the corresponding tokens in your wallet on the target chain.

#### 4. Additional Notes

* Always verify the network and token addresses before confirming transactions to avoid losses.
* For first-time users, it is recommended to test with a small amount first to ensure a smooth process.
* If you encounter any issues during the process, refer to the TaskOn help documentation or contact customer support.
