Hemi Sepolia is the ETH-denominated public testnet for the Hemi network, providing an Ethereum-compatible environment to safely deploy and validate smart contracts, cross-chain bridge flows, and dApp infrastructure before mainnet. It supports standard Ethereum tooling (wallets, RPCs, Hardhat/Foundry) and faucet-funded accounts for end-to-end testing, load generation, and monitoring.
Hemi Sepolia emphasizes production-parity for bridging and interoperability—ETH-native gas, familiar Ethereum tooling, and fast confirmations—so teams can replicate fee market and finality behavior early in development. As of Sep 2025, Hemi has not published canonical averages for gas cost, block speed, TPS, or activity; these metrics vary on testnets, so use the Hemi explorer to compare live gas prices, block times, throughput, and network activity against other networks.
Hemi Sepolia 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 Hemi Sepolia, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Hemi Sepolia as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
