An EVM-compatible testnet using ETH, HPP Sepolia enables low-cost smart contract development with full Ethereum tooling support and seamless deployment via thirdweb.
HPP Sepolia is an Ethereum-compatible (EVM) testnet for the HPP ecosystem that uses ETH as the native gas token. It is used for deploying and validating HPP smart contracts, running cross-chain bridge dry runs, and end-to-end dApp testing before mainnet. It mirrors Sepolia-style performance for quick iteration: ~12s block time, ~15 TPS, and testnet gas prices typically near 1 gwei.
HPP Sepolia stands out for predictable, low-congestion conditions and ETH-denominated gas, making performance and cost profiling straightforward versus mainnet and busier testnets. Typical metrics are ~12s blocks, ~15 TPS, and ~1 gwei gas, enabling fast confirmations with faucet-funded ETH and minimal real cost. Tight thirdweb integration (chain 181228) ensures seamless use of standard Ethereum tooling across RPCs, wallets, and explorers.
HPP 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 HPP Sepolia, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select HPP Sepolia as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on HPP Sepolia 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 HPP Sepolia 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 HPP Sepolia, ensure your wallet is connected to the HPP Sepolia network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
