An EVM-compatible testnet for Horizen, Gobi offers low-cost dApp testing with Ethereum tooling on the Zendoo-based EON sidechain secured by zero-knowledge proofs.
Horizen Gobi Testnet is the public EVM-compatible test network for Horizen EON (chain ID 1663) that uses tZEN as the gas token. It’s built for testing Solidity dApps, cross-chain bridge integrations, wallets, oracles, and indexers in a low-cost environment before deploying to mainnet. Live performance metrics (avg gas price, block time, TPS, and network activity) typically show seconds-level blocks and very low gas compared to Ethereum L1, and can be monitored via the Gobi explorer.
Horizen Gobi Testnet is unique because it combines full EVM compatibility with Horizen’s Zendoo cross-chain protocol, enabling trust-minimized interoperability between the Horizen mainchain and EON sidechains. Versus other testnets, it offers predictable low fees, rapid finality, and horizontal scalability while retaining simple MetaMask setup (tZEN gas, chain ID 1663) and production-grade bridge tooling—yielding faster blocks, low average gas cost, and high sustained TPS under load.
Horizen Gobi Testnet uses tZEN as the gas token for transaction fees. You can obtain tZEN by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge tZEN to Horizen Gobi Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Horizen Gobi Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Horizen Gobi 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 Horizen Gobi 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 tZEN on Horizen Gobi Testnet, ensure your wallet is connected to the Horizen Gobi Testnet network, enter the recipient's address, specify the amount of tZEN to send, review the gas fee, and confirm the transaction in your wallet.
