# FAQs and Troubleshooting

#### **FAQs and Troubleshooting**

This section addresses common questions and issues encountered when developing on the **XSPACE Protocol**, along with solutions to ensure a seamless development experience.

***

### **Frequently Asked Questions (FAQs)**

#### **General Questions**

**1. What is XSPACE Protocol?**

The XSPACE Protocol is a scalable, interoperable blockchain designed for real-world asset (RWA) tokenization, decentralized finance (DeFi), and smart city integration. It combines sharding and Delegated Proof-of-Stake 2.0 (DPoS 2.0) to achieve high performance and low fees.

**2. How can I interact with the XSPACE blockchain?**

You can interact with XSPACE using:

* **REST APIs** for querying the blockchain.
* **Web3.js** or **Ethers.js** for building dApps.
* The **XSPACE SDK** for streamlined development.

**3. What is GLXYC?**

GLXYC is the native token of the XSPACE Protocol, used for:

* Transaction fees.
* Staking and delegating in the DPoS mechanism.
* Payments and governance in applications like Galaxy City.

#### **Developer FAQs**

**1. How do I connect to the XSPACE Testnet?**

Use the following Testnet details:

* **RPC URL:** `https://testnet.xspace.io/rpc`
* **Chain ID:** `80001`
* **Symbol:** `GLXYC`

Add these settings to your wallet (e.g., Metamask) or development environment.

**2. How can I deploy smart contracts on XSPACE?**

Use tools like **Hardhat** or **Truffle** to write, compile, and deploy contracts. Update your configuration to include the Testnet or Mainnet RPC URL.

**3. Can I use Ethereum-based tools and contracts?**

Yes, XSPACE is EVM-compatible. You can deploy Ethereum smart contracts with minimal changes and use tools like Remix, Hardhat, and Truffle.

**4. What is XATS?**

The **XSPACE Asset Tokenization Standard (XATS)** is a framework for creating and managing tokenized real-world assets like real estate, commodities, and infrastructure.

**5. How do I get Testnet GLXYC tokens?**

Visit the **XSPACE Testnet Faucet**:\
[https://testnet-faucet.xspace.io](https://testnet-faucet.xspace.io/)\
Enter your wallet address to receive free tokens for testing.

#### **Troubleshooting Common Issues**

**1. I’m unable to connect to the Testnet.**

* **Possible Causes**:
  * Incorrect RPC URL or Chain ID.
  * Network latency or downtime.
* **Solutions**:
  * Verify Testnet details:
    * RPC URL: `https://testnet.xspace.io/rpc`
    * Chain ID: `80001`
  * Check [XSPACE Status](https://status.xspaceprotocol.io/) for network updates.

***

**2. My smart contract deployment fails.**

* **Possible Causes**:
  * Insufficient GLXYC balance for deployment.
  * Syntax errors in the contract.
* **Solutions**:
  * Ensure your wallet has enough Testnet GLXYC.
  * Compile your contract to check for errors before deployment.

    ```bash
    npx hardhat compile
    ```

***

**3. Transactions are not being confirmed.**

* **Possible Causes**:
  * Low gas fees.
  * Network congestion.
* **Solutions**:
  * Increase gas fees in your transaction settings.
  * Verify the network status via the XSPACE Explorer:\
    [https://explorer.xspaceprotocol.io](https://explorer.xspaceprotocol.io/)

***

**4. I can’t interact with my deployed contract.**

* **Possible Causes**:
  * Incorrect ABI or contract address.
  * Network mismatch (Mainnet vs. Testnet).
* **Solutions**:
  * Confirm the ABI matches the deployed contract.
  * Verify the contract address in the XSPACE Explorer.
  * Ensure your dApp connects to the correct network.

***

**5. Validator node setup fails.**

* **Possible Causes**:
  * Missing dependencies (e.g., Docker).
  * Incorrect configuration file.
* **Solutions**:
  * Verify that Docker is installed and running:

    ```bash
    docker --version
    ```
  * Check your `config.yaml` file for accuracy.

***

**6. Cross-chain transactions are delayed.**

* **Possible Causes**:
  * Insufficient liquidity in the bridge.
  * Network congestion on the destination chain.
* **Solutions**:
  * Monitor bridge liquidity using the XSPACE Explorer.
  * Ensure the destination blockchain is operational and not congested.
