An EVM-compatible Layer 2 on Ethereum, Karak powers restaking-native applications with multi-asset security and low-cost, fast transactions using ETH for gas.
Karak is an Ethereum‑aligned universal restaking protocol and L2 Mainnet where gas is paid in ETH, designed to secure on‑chain services (AVSs) and appchains via risk‑isolated slashing vaults. Primary use cases include restaking ETH/LSTs and other assets to secure oracles, DA layers, rollups, and coprocessors, plus deploying dApps to a restaked L2 with shared security. For bridging and UX, fees are typically sub‑$0.05 with ~2‑second blocks and double‑digit TPS; check the Karak explorer for live activity as metrics fluctuate with demand.
Karak is unique for universal, multi‑asset restaking with per‑service risk isolation (vaults) and programmable slashing, which caps risk while letting builders buy exactly the security they need. It runs a permissionless marketplace that matches node operators with services and can export restaked security to external rollups, improving capital efficiency and rewards. Performance is L2‑class—ETH gas, seconds‑level block times, and low‑cent fees—while the differentiator versus other networks is its restaked security model rather than raw TPS; compare live TPS, block speed, and active addresses on its explorer.
Karak uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge.
To bridge ETH to Karak, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Karak as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Karak 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 Karak 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 Karak, ensure your wallet is connected to the Karak network, enter the recipient's address, specify the amount of ETH to send, review the gas fee, and confirm the transaction in your wallet.
