#### **Bridge User Guide: PhionAI, PHRToken, WrappedSOL, and SOL** <a href="#bridge-user-guide-phronai-phrtoken-wrappedeth-and-eth" id="bridge-user-guide-phronai-phrtoken-wrappedeth-and-eth"></a>

#### This guide will walk you through the steps to bridge tokens between the PhionAI and Sepolia networks, converting PhionAI tokens to PHRToken (and vice versa) as well as WrappedETH on PhionAI to ETH on Sepolia (and vice versa). <a href="#bridge-user-guide-phronai-phrtoken-wrappedeth-and-eth" id="bridge-user-guide-phronai-phrtoken-wrappedeth-and-eth"></a>

**1. Connecting to the Bridge Platform**

* **Open the Bridge Interface**: Access the bridge platform and connect your multi-network wallet, such as MetaMask.
* **Select the Network**: Choose either **Sepolia** (for PHRToken/ETH) or **PhionAI** (for PhionAI/WrappedETH), depending on the direction of your transfer.

**2. Approve Token Transfers for Bridging**

1. **Choose Your Token**:
   * For **PhionAI to PHRToken**, select the PhionAI token on the PhionAI network.
   * For **WrappedETH to ETH**, select WrappedETH on the PhionAI network.
2. **Approve the Bridge Contract**:
   * You must allow the bridge contract to access your tokens for transfer. This approval only needs to be done once per token type. Confirm the approval request in your wallet.

**3. Converting Tokens (Bridging Transactions)**

1. **Enter the Amount**: Specify the amount of the token you wish to bridge.
2. **Initiate the Transfer**:
   * *For PhionAI to Sepolia*: Select “Transfer” to move PhionAI (or WrappedETH) to the Sepolia network. This locks the original tokens on PhionAI and mints PHRToken (or ETH) on Sepolia.
   * *For Sepolia to PhionAI*: Select “Transfer” to move PHRToken (or ETH) to the PhionAI network. The bridge contract locks the tokens on Sepolia and releases the equivalent amount on PhionAI as PhionAI or WrappedETH.

**4. Monitoring the Transaction**

1. **Transaction History**: Check the “Transaction History” section on the bridge interface for updates on your transfer status.
2. **Claim Tokens**:
   * For some transfers, you may need to click “Claim” once the transaction is confirmed on the destination network to complete the bridge process.
   * Tokens will appear in your wallet once finality is achieved.

**5. Withdrawing Tokens (Optional)**

* You can reverse the process if you wish to return PHRToken to PhionAI or WrappedETH to ETH. Follow the same steps, choosing the correct token and network for the direction of transfer.

**Conversion Rates and Fees**

* **Conversion Rates**: All bridge conversions are 1:1, meaning that PhionAI always converts to an equivalent amount of PHRToken, and WrappedETH always converts to an equivalent amount of ETH.
* **Fees**: Gas fees and potential bridge fees apply depending on network congestion and platform requirements. Confirm fees in the bridge interface before transferring.

This guide covers all steps for securely converting tokens between PhionAI and Sepolia networks. For further assistance, refer to the bridge’s support documentation or explore transaction history via the Sepolia and PhionAI blockchain explorers.
