Karak is a multi-asset restaking protocol launched in 2024 that aims to expand the restaking landscape beyond ETH and LSTs. It supports a diverse collateral set—ETH, LSTs, LRTs, BTC derivatives, and stablecoins—and introduces K2, a restaking-secured Layer-2 network for Distributed Secure Services (DSS). While still smaller than leader EigenLayer EigenLayer, Karak has carved a niche with cross-chain support and a distinctive security model. This review examines its design, numbers, risks, and competitive standing as of 2026.
What it is
Karak is a restaking protocol built to allow users to deposit multiple asset types—not just ETH or liquid staking tokens—to secure additional decentralized services. Founded in 2024, it extends the restaking primitive popularized by EigenLayer EigenLayer, aiming to be more inclusive by accepting BTC derivatives, stablecoins, and various yield-bearing tokens. The protocol comprises two main components: the restaking layer on Ethereum and partner chains, and K2, a custom Layer-2 built on Arbitrum Nitro that uses restaked assets for its own security. Karak’s governance is handled by the Karak Foundation, and it has no native token as of 2026. The platform targets developers seeking to launch DSSs that can draw on a broad security pool.
How it works
Users deposit supported collateral—ETH, LSTs like stETH, LRTs, wrapped BTC such as WBTC, and stablecoins like USDC—into Karak vaults deployed on Ethereum and connected L2s (Arbitrum, Mantle, BNB). These assets are then pooled and delegated to operators who run Distributed Secure Services (DSS). A DSS can be any application requiring cryptoeconomic security, such as oracle networks, cross-chain bridges, data availability layers, or even rollup sequencers. Operators must stake a minimum amount (which varies by DSS) and are subject to slashing if they misbehave, as validated by the service’s specific rules enforced onchain. The reward model is bilateral: users who deposit earn a share of the fees or tokens paid by the DSS, while operators earn additional compensation for their work. K2 is Karak’s flagship DSS: a universal restaking-secured L2 built with Arbitrum Nitro technology. Assets restaked through Karak on Ethereum are used to secure K2’s validator set, and the L2 in turn hosts more DSSs, creating a flywheel. Smart contracts are organized around a hub-and-spoke model: the core EigenLayer-like contract on Ethereum manages restaking, while spoke contracts on other chains handle multi-chain delegation. The system is upgradable via a multisig, with the Karak Foundation as the current administrator.
Key numbers
As of 2026-07-15, Karak reports a total value locked of approximately ~$6.7 million across its restaking pools — a steep collapse from prior peaks above $700 million as the restaking sector consolidated. The protocol supports five blockchain networks: Ethereum, Arbitrum, Mantle, BNB Chain, and its own K2 L2. It has undergone three independent smart-contract audits from Sigma Prime, Cantina, and Spearbit. The platform launched in 2024 and does not yet have a native governance or utility token. K2, its restaking-secured Layer-2, went live in 2025 and processes a modest but growing number of transactions.
Security and audits
Karak’s smart contracts have been audited by three well-regarded firms: Sigma Prime, Cantina, and Spearbit. No public incidents or exploits have been reported since launch, though the protocol is relatively young (2024). The system is likely governed by a multisig controlled by the Karak Foundation, which holds upgrade authority—a common but centralized measure. The K2 L2 introduces additional attack surface as a new blockchain; its security depends on the proper functioning of the restaking mechanism and the fidelity of the bridging layer between Ethereum and K2. There is no public bug bounty program detailed, and the codebase’s complexity (multi-chain, multi-asset) raises the potential for undetected edge-case vulnerabilities. Slashing conditions are defined per DSS and enforced by the protocol’s contracts, but a flaw in a DSS’s slashing logic could lead to unfair penalization or insufficient protection. Additionally, the Karak Foundation’s multisig control creates a central point of trust. The immutability of restaked assets on K2 relies on the underlying Arbitrum Nitro stack and fraud proofs, which have their own security considerations. Users should note that while audits reduce risk, they do not guarantee safety.
Strengths
Multi-asset restaking differentiates Karak from ETH-only protocols, supporting BTC and stablecoins, which diversifies the security base beyond the ~$6.7 million TVL. Cross-chain support across five networks (Ethereum, Arbitrum, Mantle, BNB, K2) gives operators and DSSs flexibility, compared to EigenLayer’s EigenLayer Ethereum-only focus. Three separate audit firms (Sigma Prime, Cantina, Spearbit) provide a solid security review foundation for a protocol of its age.
Weaknesses and risks
A collapsed TVL of ~$6.7 million versus roughly $12 billion for EigenLayer EigenLayer means less economic security to absorb slashing events, making it riskier for large DSSs. Governance centralization under the Karak Foundation and lack of a token remove community oversight and could lead to decisions that don’t align with user interests. K2 is a new L2 with limited adoption; if it fails to gain traction, the value proposition of restaking for its own security is diminished, and bridges to K2 could be an attack vector.
How it compares
EigenLayer EigenLayer dominates restaking with $12 billion TVL and an Ethereum-only model launched in 2023, carrying audits from Sigma Prime, Consensys Diligence, and Cantina. Karak’s ~$6.7 million TVL is now a tiny fraction of EigenLayer’s, but it offers multi-chain and multi-asset support that EigenLayer lacks. Symbiotic Symbiotic, another competitor at $2 billion TVL, also accepts any ERC-20 collateral but remains Ethereum-only. Karak’s audit coverage (3 firms) is comparable to EigenLayer’s and stronger than Symbiotic’s 2. Karak’s K2 L2 is unique—neither competitor has a dedicated L2 secured by restaking. However, EigenLayer’s broader ecosystem of 10+ AVSs in production gives it a network effect edge. Overall, Karak is a credible alternative for those wanting risk diversification and cross-chain operations, but it trails in total security budget and maturity.
Verdict
Karak brings meaningful innovation to restaking through multi-asset and multi-chain support, and its K2 L2 could become a model for restaking-secured execution environments. However, the protocol has contracted dramatically, with only ~$6.7 million in TVL and no major incidents to validate its security promises. The centralized governance and lack of a token also raise concerns about long-term alignment. For users comfortable with higher risk and interested in diversifying their restaking exposure beyond EigenLayer EigenLayer, Karak is worth monitoring, but it’s not a bluechip and its user base has largely evaporated. Rating 4.0/10.
