What is X1 Fastnet?

X1 Fastnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on X1 Fastnet once you add the network configuration.

Why do you need to add X1 Fastnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on X1 Fastnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

How to add X1 Fastnet to your wallet

  1. 1

    Click Add to wallet

    Press the "Add to wallet" button above. MetaMask, OKX Wallet, Rabby Wallet or Trust Wallet will show a popup asking you to confirm adding the X1 Fastnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the X1 Fastnet network details: Chain ID 4003, native token XN. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

    Switch to the new network

    After confirming, your wallet automatically switches to X1 Fastnet. You can start transacting right away — you will need XN to pay gas fees.

Important notice

  • •Always verify Chain ID 4003 before confirming — attackers sometimes create fake networks with similar names but different Chain IDs
  • •You need XN tokens in your wallet to pay gas fees for transactions on X1 Fastnet
  • •Data on this page is sourced from chainid.network — the community-verified Ethereum chain registry
  • •If the "Add to wallet" button doesn't work, your wallet may not support wallet_addEthereumChain — add the network manually using the details below

Frequently asked questions

Is it safe to add X1 Fastnet to MetaMask?▾
Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.
What is X1 Fastnet Chain ID?▾
The Chain ID of X1 Fastnet is 4003. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need XN tokens to use X1 Fastnet?▾
Yes. Every transaction on X1 Fastnet requires XN to pay gas fees. You can purchase XN on exchanges and bridge it to X1 Fastnet, or use a faucet if this is a testnet.
What is the X1 Fastnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the X1 Fastnet blockchain — sending transactions, reading balances, and checking state. One popular X1 Fastnet RPC is https://x1-fastnet.xen.network. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says X1 Fastnet already exists when I click Add — what do I do?▾
That's completely normal. If X1 Fastnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added X1 Fastnet but the network won't load — what's wrong?▾
The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
