Cyber Testnet is the public EVM-compatible test network for Cyber, an Ethereum Layer 2 (OP Stack) that uses ETH as the native gas token and targets social and consumer dApps. It’s used to safely test bridges, ERC-4337 account abstraction wallets, sponsored gas/paymasters, session keys, social graph and content primitives, NFTs, and high-frequency microtransactions before mainnet. Typical performance: average gas cost under $0.01 for simple calls, ~2s block time, roughly 10–100+ TPS in load tests, and bursty developer-driven activity—substantially cheaper and faster than Ethereum mainnet (check cyber.co for live stats).
Cyber Testnet is unique for its social-first design: native account abstraction (ERC‑4337) with session keys and gas sponsorship, ETH-denominated fees for familiar UX, and full OP Stack/EVM tooling compatibility. This combination enables consumer-grade flows (likes, follows, mints, tips) at low cost with fast confirmations while retaining standard Ethereum developer tools and bridge integrations. Compared with general-purpose L1s and many L2s, it prioritizes creator-economy and social use cases, optimizing for high-volume, low-value interactions.
Cyber 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 Cyber Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Cyber Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Cyber 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 Cyber 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 Cyber Testnet, ensure your wallet is connected to the Cyber 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.
