An EVM-equivalent zkEVM Layer 2 testnet mirroring Scroll Mainnet, offering low-cost, fast transactions with Sepolia ETH and full Ethereum tooling for pre-deployment testing.
Scroll Sepolia is the public zkEVM test network that mirrors Scroll mainnet on Ethereum’s Sepolia, using ETH as the native token. It’s used to safely test smart contracts, cross-chain bridging, wallets, indexers, and EIP‑4844 blob flows before production; gas is paid with faucet Sepolia ETH and has no real-world value. Indicative testnet performance: ~2s L2 block times, negligible fees (fractions of a cent equivalent), and throughput in the tens to low hundreds of TPS depending on load.
Scroll Sepolia is unique for its bytecode-level EVM equivalence (deploy the exact Ethereum bytecode with no changes) and zk-rollup proofs that enable fast L2→L1 finality in minutes versus multi-day optimistic exits, plus native EIP‑4844 support to lower data costs. Compared to other testnets/L2s, it offers production-parity tooling (Geth-based stack, standard RPC) with a stable block cadence (~2s), very low gas costs, and active developer usage for bridge and contract testing. In practice this yields low fees, fast blocks, and scalable TPS under stress—ideal for benchmarking dApps prior to mainnet deployment.
Scroll 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 Scroll Sepolia Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Scroll Sepolia Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Scroll 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 Scroll 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 Scroll Sepolia Testnet, ensure your wallet is connected to the Scroll 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.
