Frequently asked questions

XR Sepolia is the public EVM-compatible testnet for the XR One network, using the valueless tXR token to pay gas. It lets teams safely test smart contracts, wallets, and cross-chain bridge flows end‑to‑end with faucets and test assets before mainnet deployment. Developers use it to validate fees, confirmations, and interoperability without financial risk or impacting production state.

XR Sepolia is unique for its tXR-based gas model (not ETH), bridge-first tooling, and parity with popular EVM tooling, making cross-chain testing straightforward. Public explorers surface practical performance metrics—average gas cost in fractions of tXR, seconds-level block speed, sustained testnet throughput in the double‑digit TPS range, and visible activity (tx/day, active addresses)—to benchmark against Ethereum Sepolia’s ~12 s blocks and lower TPS. This combination of negligible fees, rapid confirmations, and purpose-built bridging support accelerates iterative testing for dApps and bridge integrations.

XR Sepolia uses tXR as the gas token for transaction fees. You can obtain tXR by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).

To bridge tXR to XR Sepolia, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select XR Sepolia as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on XR Sepolia you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.

To add XR Sepolia to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.

To send tXR on XR Sepolia, ensure your wallet is connected to the XR Sepolia network, enter the recipient's address, specify the amount of tXR to send, review the gas fee, and confirm the transaction in your wallet.
