An Ethereum-compatible zero-knowledge testnet leveraging Sepolia and ETH gas, with Chain ID 555271, for low-cost, secure, scalable dApp development and integration testing.
Xsolla ZK Sepolia Testnet is an Ethereum Sepolia–anchored zk-rollup environment used by the Xsolla cross-chain bridge to simulate mainnet-grade transfers and on-chain payment flows with ETH as the native gas. It lets developers safely test contract deployments, bridging, fee estimation, and wallet UX for games and dApps without risking real assets. Key performance metrics (average gas cost, block speed, TPS, and network activity) are not officially published and fluctuate on testnets; benchmark them via a public explorer or by querying eth_gasPrice and recent block timestamps for comparison with other Sepolia-based ZK L2s.
It pairs ZK validity proofs for fast, confidence-worthy finality with full EVM compatibility and ETH-native fees, making it drop-in for standard tooling (e.g., MetaMask, Hardhat) while mirroring the Xsolla bridge’s production flow end-to-end. Unlike generic testnets, it is purpose-built around cross-chain payment and asset-settlement scenarios common to gaming, enabling realistic testing of bridge latency, retry logic, and fee behavior. For apples-to-apples comparison against other networks, track median block time, effective TPS under your workload, average gas in gwei, and active addresses, noting these metrics vary widely on testnets and may not be publicly posted for this network.
Xsolla ZK Sepolia Testnet uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ETH to Xsolla ZK Sepolia Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Xsolla ZK Sepolia Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Xsolla ZK Sepolia 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 Xsolla ZK Sepolia 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 ETH on Xsolla ZK Sepolia Testnet, ensure your wallet is connected to the Xsolla ZK Sepolia Testnet network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
