Introduction to Restaking

Restaking has gained traction as a significant innovation in the realm of decentralized finance, largely due to the pioneering efforts of EigenLayer. Staking involves locking up a specific cryptocurrency to secure its own network, such as staking Ether (ETH) to secure Ethereum. Restaking, however, extends this concept by allowing a cryptocurrency to secure decentralized projects outside its native network. For instance, using ETH to secure project X. This approach aims to create a common security reserve that can enhance the security of various projects utilizing restaking protocols.

The primary advantage of restaking lies in its ability to leverage a single token to contribute to the security of multiple projects. However, this also increases the token's exposure to slashing risks, which are financial penalties imposed on "bad" actors in the staking and restaking processes. Restaking addresses a critical challenge: the high cost of economic security for decentralized projects, especially during their nascent stages. Projects that rely solely on staking their native tokens can be vulnerable to attacks, particularly if the token's value is low. High staking rewards to mitigate these risks often lead to significant inflation. By restaking a token like ETH, projects can depend on a high-capitalization asset and reduce the token emissions related to network security.

This concept of shared economic security is not entirely new, having been explored with "Parachains" in the Polkadot ecosystem and "Interchain Security" in the Cosmos ecosystem. Restaking offers more flexibility to projects, allowing them to use this security without facing penalties if they choose to discontinue it after some time.

The Rise of Restaking Protocols

The perceived potential of restaking has spurred the rapid emergence of various protocols, each striving to connect supply with demand. The supply side involves accumulating substantial value locked within their protocol, while the demand side consists of projects seeking the security provided by restaking protocols. Differentiation among these protocols often hinges on the type of collateral accepted. The inherent value of a restaked token is crucial, but other factors such as volatility and dependencies also play significant roles. For example, native ETH has greater value than a liquid staking token like Lido's stETH, which depends on the issuing protocol.

Key Restaking Protocols

EigenLayer

As the first restaking protocol to launch, EigenLayer has a head start and has quickly attracted significant locked-in value, thanks in part to numerous projects announcing their intention to launch on it early. EigenLayer has introduced the EIGEN token, which enhances security by facilitating consensus on data not directly verifiable on the staking network but validated through intersubjective agreement among human observers. Currently, EigenLayer supports native ETH staking, offering a pure form of collateral without relying on liquid staking tokens.

EigenLayer secures Actively Validated Services (AVS), the technical term for projects utilizing its security. CEO Sreeram Kannan envisions EigenLayer as a foundation for developing numerous applications providing specialized services to both Web3 and Web2 participants. EigenLayer's centralization around Eigen Labs allows for controlled development, with the startup building its own AVS and maintaining the ability to modify smart contracts.

Karak

Karak, the second publicly announced restaking protocol, differentiates itself by accepting a wide variety of tokens, including exotic options like the USDe stablecoin from Ethena and derivative tokens from Pendle. Despite this diversity, Karak lags behind EigenLayer in traction, having taken several months to reach $1 billion in immobilized value. Recently, Karak announced a partnership with Wormhole and its plans to build an AVS aggregating data availability networks like Celestia and EigenDA.

Symbiotic

Launched in June 2024, Symbiotic positions itself as a direct competitor to EigenLayer, backed by Lido's co-founders Konstantin Lomashuk and Vasiliy Shapovalov. Symbiotic aims to extend the use of Lido's liquid staking token, stETH, in restaking activities. Unlike EigenLayer, Symbiotic uses a vault system allowing users to choose the AVS they wish to secure, rather than delegating this choice to operators. Symbiotic's strategic approach emphasizes neutrality, with immutable smart contracts and no AVS built by its own team.

Babylon

Distinct from the protocols above, Babylon operates on the Bitcoin network, aiming to enable the restaking of native bitcoins. This innovation could significantly enhance Bitcoin's utility, currently limited to mere possession. Babylon has reportedly integrated a slashing system on the Bitcoin network, although it remains in the testnet phase.

Other Protocols and Market Dynamics

Other restaking protocols like Picasso and Solayer target different ecosystems, such as Cosmos and Solana, but have yet to achieve the same traction as Ethereum-based protocols. Restaking is predominantly rooted in the Ethereum ecosystem, with Bitcoin also showing potential through projects like Babylon.

Currently, EigenLayer remains the leader in restaking, bolstered by native ETH staking support and the introduction of the EIGEN token. Symbiotic emerges as a strong contender, emphasizing neutrality and direct AVS selection. Karak, while offering broad token support, has yet to match EigenLayer's traction. Babylon holds promise by expanding Bitcoin's utility, though it is still in early development stages.

The theoretical potential of shared security protocols is vast. On the supply side, they tap into the substantial market caps of Bitcoin and Ethereum. On the demand side, they target a wide array of infrastructure projects, including alternative Layer-1s, Layer-2s, oracles, and decentralized physical infrastructure networks (DePINs). This dual-market approach positions shared security protocols to capture a significant portion of the cryptocurrency market.

By integrating various infrastructure projects under the security umbrella of BTC and ETH, these protocols add a critical use case to the top two crypto assets, thereby enhancing their value proposition. The substantial buy-in from prominent asset holders underscores the high stakes and significant potential for success.

However, these protocols are still in their early stages, and their tokens are not yet publicly tradable. Although there is currently no pressure from token unlocks, there will likely be an overhang once the tokens are launched. EigenLayer, for example, plans to airdrop 15% of its initial supply to the community, with 30% reserved for the treasury and 55% for insiders and investors. This distribution strategy could influence market dynamics upon launch.

Current Challenges

The initial enthusiasm for the launch of these protocols has waned. User fatigue has set in for infrastructure protocols, and investor fatigue is noticeable for low-float tokens. Even EIGEN’s launch received a lukewarm response from the community. While these protocols have proven capable of generating security capital, there are concerns regarding the sustainable demand for their services.

The primary tailwind for these protocols is the anticipated full launches and associated token airdrops. Significant community involvement during the launch phases can generate substantial attention and traction. High token valuations during the launch could create a wealth effect, bolstering the ecosystem.

There is considerable investor appetite for infrastructure projects. EigenLayer, Babylon, and Karak have raised $100 million, $70 million, and $48 million, respectively, in their most recent private rounds. These large fundraises enable these projects to invest in growth and partnerships, anchoring public market prices for eventual token launches. High token valuations can incentivize usage and adoption.

A major challenge for shared security protocols is ensuring high demand to provide worthwhile yields to security suppliers. The long-term success hinges on attracting high-quality infrastructure protocols that are willing to pay for enhanced security.

Users have become more transactional and opportunistic, leading to a decline in usage after the conclusion of incentives for multiple large infrastructure protocols. Shared security protocols must build strong moats to retain users and prevent a rapid decline post-launch.

Conclusion

Restaking and shared security protocols hold the potential to revolutionize the DeFi landscape by providing enhanced security and additional yield opportunities. While these protocols face significant challenges, their innovative approach and the backing of major investors provide a solid foundation for future growth. The upcoming launches and token airdrops are crucial events that will shape the trajectory of these protocols, determining their ability to sustain user interest and demand. As the space evolves, continuous adaptation and robust user retention strategies will be essential for long-term success.
