TL;DR
-
ION Protocol was founded by two former employees of Blockchain Capital, who previously participated in investment research for Eigenlayer and have received backing from Blockchain Capital and angel investors within the Restake ecosystem.
-
Compared to LST assets, LRT assets exhibit higher variance in rewards and penalties, making liquidity provision and DeFi composability significantly more challenging.
-
LRT assets benefit from ION’s collateralized lending model, which enables trustless liquidations via consensus-layer node monitoring—eliminating the need for oracles—while allowing LRT holders to achieve "one-click, four-way yield farming."
-
ION’s ZKML-based node monitoring solution is built on Eigenlayer’s consensus layer, with a risk management framework capable of supporting the broader Eigenlayer DeFi ecosystem.
-
The emerging narrative combining ZKML and restaking positions ION as an innovator in Eigenlayer’s ecosystem; furthermore, ION’s ZKML solution can serve other protocols and blockchains utilizing restaking architectures.

The restaking sector is booming, with projects like Swell, Renzo, EtherFi, and Eigenpie launching rapidly—echoing the excitement of the previous LSD summer. Meanwhile, many projects from last year’s LSD summer, such as Lybra and AGI, are already fading. Will Restake Summer repeat the story of LSD summer—merely repackaging old ideas, swapping mining tokens for Points, enabling large holders to farm, dump, and exit, while leaving project teams, retail users, exchanges, and investors to do the heavy lifting?
This time, however, things are different. Recent developments such as ION Protocol’s proposal for a ZKML-powered node risk infrastructure around Eigenlayer reveal meaningful innovation and differentiation within the restaking ecosystem.
First, the underlying assets differ fundamentally. Though differing by just one letter—LST vs. LRT—the implications are enormous. ION Protocol was founded by two former Blockchain Capital employees, one of whom led early investment research into Eigenlayer and helped drive Blockchain Capital’s lead investment in the project. Leveraging their deep understanding of Eigenlayer, they defined LRTs (liquid restaked tokens) as NFT-like assets from day one, recognizing that each LRT carries unique risk and return profiles.
How do LRT assets (e.g., ezETH, rswETH, rsETH, eETH) differ from traditional LSTs like stETH, swETH, or rETH? The key differences lie in liquidity and yield characteristics.
LRTs represent restaked positions, where restaking introduces new risks and rewards, enabling a single asset to perform double duty—one stake securing Ethereum, another securing AVSs (Actively Validated Services).
Divergent Rewards: LSTs earn consistent ETH staking yields. In contrast, LRTs earn variable market-driven yields depending on the AVS they support—AltLayer clients, Lagrange, Mantle, etc.—each offering vastly different reward structures. As a result, LRT returns are far less uniform than those of LSTs, exhibiting high variance.
Divergent Risks: On Eigenlayer, nodes run AVS instances—essentially validator groups providing security services to Trust Networks. If these nodes misbehave, slashing penalties apply. Different AVSs carry distinct slashing conditions and risk levels, directly impacting the net returns of restakers.
In short, this "second job" performed by restakers differs significantly from uniform POS staking rewards and risks. It involves two distinct matching markets: one for usage-based rewards and another for AVS selection. These dual dynamics mean that as the LRT landscape expands, each token becomes increasingly customized—precisely why ION’s founders initially conceptualized them as NFT-like assets.
The greater uniqueness of LRTs makes it harder to aggregate them into unified liquidity pools compared to standardized LSTs, complicating trading and integration into DeFi ecosystems.
To address this challenge, ION introduced a ZKML-based AVS monitoring solution that evaluates each validator’s balance and penalty exposure to assess the intrinsic value of individual LRT assets. This consensus-layer monitoring approach allows ION’s lending protocol to operate without relying on CEX/DEX price feeds. Consequently, LRT projects can avoid costly liquidity mining initiatives and reduce overhead associated with bootstrapping liquidity.
Collateralized lending is a foundational DeFi primitive. For this reason, nearly all LRT projects are integrating with ION Protocol at launch. LRT holders depositing into ION gain access to “one-click, four-way farming”: earning Eigenlayer Points + AVS Airdrops + LRT Airdrops + ION Airdrops. Moreover, leveraged borrowers can generate interest income, delivering up to 3x staking yields (excluding ION airdrops) for ETH/stETH depositors.
For Eigenlayer, ION’s solution plays a critical role. Prior to ION’s emergence, Vitalik raised concerns about over-reliance on Ethereum’s consensus-layer trust through restaking. Eigenlayer’s founder engaged in a notable public debate with Vitalik on this topic [1]. Later, Vitalik proposed the concept of “home stakers” [2], aligning closely with Eigenlayer’s vision of Heterogeneous Stakers [3]. ION’s ZKML-powered node monitoring provides a consensus-layer-native risk control mechanism—tracking validator balances and slashing events. The safer the consensus-layer nodes, the lower the liquidation risk for corresponding LRT assets, thereby strengthening the trust linkage from lending protocols back to the base layer.
ZKML itself represents a major emerging narrative—merging zero-knowledge proofs with AI. Modulus Labs, backed by 1kx and Variant Fund, has collaborated with the ION team over several months to develop this ZKML solution, further validating its practical feasibility and demonstrating how ZK and AI capabilities can be applied directly at the consensus layer. This framework isn’t limited to Eigenlayer—it can be adopted by any blockchain or protocol leveraging staking and restaking mechanisms (@babylon_chain, @Picasso_Network, @CelestiaOrg), opening broad applicability across the modular stack.
