What is XR Sepolia?

XR Sepolia 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 XR Sepolia once you add the network configuration.

Why do you need to add XR Sepolia to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on XR Sepolia, 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 XR Sepolia 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 XR Sepolia network.

  2. 2

    Confirm in your wallet

    Your wallet shows the XR Sepolia network details: Chain ID 2730, native token tXR. 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 XR Sepolia. You can start transacting right away — you will need tXR to pay gas fees.

Important notice

  • •Always verify Chain ID 2730 before confirming — attackers sometimes create fake networks with similar names but different Chain IDs
  • •You need tXR tokens in your wallet to pay gas fees for transactions on XR Sepolia
  • •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 XR Sepolia 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 XR Sepolia Chain ID?▾
The Chain ID of XR Sepolia is 2730. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need tXR tokens to use XR Sepolia?▾
Yes. Every transaction on XR Sepolia requires tXR to pay gas fees. You can purchase tXR on exchanges and bridge it to XR Sepolia, or use a faucet if this is a testnet.
What is the XR Sepolia RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the XR Sepolia blockchain — sending transactions, reading balances, and checking state. One popular XR Sepolia RPC is https://xr-sepolia-testnet.rpc.caldera.xyz/http. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says XR Sepolia already exists when I click Add — what do I do?▾
That's completely normal. If XR Sepolia is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added XR Sepolia 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.
