An EVM-compatible Ethereum Layer 2 testnet on Sepolia for Metis, featuring a decentralized sequencer and ultra-low fees, using tMETIS for fast, low-cost dApp validation.
Metis Sepolia Testnet is the EVM-equivalent Layer 2 test network for Metis on Ethereum Sepolia, using tMETIS for gas and mirroring mainnet features such as the decentralized sequencer and canonical bridge. It’s used to deploy and debug smart contracts, test cross-chain bridging/messaging, and run end-to-end QA for DeFi, NFTs, gaming, and wallet/oracle integrations before mainnet. Expect seconds-level block confirmations and near-zero fees suitable for high-frequency CI; consult the Sepolia explorer for live block speed, TPS, gas cost, and activity metrics.
Metis Sepolia is unique in that it reflects Metis’s production-grade decentralized sequencer architecture, allowing teams to validate liveness and transaction ordering beyond single-sequencer L2 testnets. It provides full Ethereum tooling parity (Solidity/Vyper, Hardhat/Foundry) with predictable low tMETIS gas fees and seconds-level blocks, enabling L2-scale load tests (tens to hundreds of TPS) without cost risk. This combination of decentralized sequencing plus low-cost, high-throughput EVM execution makes it a performant staging ground for cross-chain apps compared to other testnets.
Metis Sepolia Testnet uses tMETIS as the gas token for transaction fees. You can obtain tMETIS by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge tMETIS to Metis Sepolia Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Metis Sepolia Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Metis 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 Metis 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 tMETIS on Metis Sepolia Testnet, ensure your wallet is connected to the Metis Sepolia Testnet network, enter the recipient's address, specify the amount of tMETIS to send, review the gas fee, and confirm the transaction in your wallet.
