An EVM-compatible blockchain testnet (Chain ID 4157), CrossFi Testnet enables fast, low-cost payments and DeFi development with XFI gas, offering rapid finality.
CrossFi Testnet is the public testing network for the CrossFi blockchain (native currency: XFI) where teams validate cross‑chain dApps, wallets, and bridge integrations before mainnet. It enables end‑to‑end simulations of liquidity movement, payments, and DeFi flows to test contracts, fees, and finality without risking real funds. For benchmarking, track average gas cost (in XFI), median block time, throughput (TPS), and transaction/activity via the official resources on https://crossfi.org, as these metrics vary by release and load.
CrossFi Testnet is distinguished by its focus on interoperability and bridge‑centric workflows—routing, fee estimation, and multi‑chain message passing are first‑class testing targets with faucet‑funded XFI and ready RPC/SDK tooling. Unlike general‑purpose testnets, it is designed to help you benchmark cross‑chain transfers by surfacing live metrics for comparison—average gas cost (XFI), block speed, TPS, and network activity. For current numbers, reference the live explorer/telemetry linked from https://crossfi.org.
CrossFi Testnet uses XFI as the gas token for transaction fees. You can obtain XFI by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge XFI to CrossFi Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select CrossFi Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on CrossFi Testnet 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 CrossFi Testnet 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 XFI on CrossFi Testnet, ensure your wallet is connected to the CrossFi Testnet network, enter the recipient's address, specify the amount of XFI to send, review the gas fee, and confirm the transaction in your wallet.
