An EVM-compatible blockchain testnet (Chain ID 89138) for Spheron Network using ETH gas, enabling low-cost transactions and direct integration with decentralized compute and storage tooling.
Spheron Testnet is an Ethereum-compatible test network where gas is paid in ETH test tokens, built for safely validating smart contracts and app workflows before mainnet. Primary use cases include rapid prototyping with Hardhat/Foundry, end-to-end testing of Spheron Compute and decentralized storage integrations, and dry-running cross-chain bridge flows under realistic network conditions.
Spheron Testnet is unique for its native integration with Spheron’s stack—Compute, IPFS/Arweave storage, and global hosting/CDN—so teams can test on-chain logic alongside off-chain infrastructure within one CI/CD-driven environment. It also maintains Ethereum-tooling parity and public faucets while surfacing real-time performance metrics (average gas cost, block speed, TPS, and network activity) via its explorer/monitors for benchmarking against Sepolia and other EVM testnets.
Spheron 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 Spheron Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Spheron Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Spheron 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 Spheron 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 Spheron Testnet, ensure your wallet is connected to the Spheron 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.
