Mellow Protocol

The Problem: LRT Monoculture

By early 2024, liquid restaking had become one of the largest sectors in DeFi, with EigenLayer enabling ETH stakers to "restake" their stake to secure additional protocols. However, most liquid restaking protocols offer a single LRT product with opinionated risk settings. This creates a one-size-fits-all dynamic that doesn't work for institutions with specific risk mandates or protocols building atop restaking.

Mellow Protocol solves this by providing the primitives, the vault infrastructure, risk parameters, and operator coordination layer, that let any entity create their own LRT. Rather than competing with EtherFi or Renzo, Mellow is the infrastructure layer underneath them.

How It Works

Protocols using Mellow deploy a "vault" that accepts ETH deposits, selects which EigenLayer operators to delegate to, and sets risk parameters (maximum slashing exposure, operator diversification requirements). This vault then issues an LRT representing the restaked position. The vault creator controls the risk profile; Mellow provides the smart contract infrastructure.

Symbiosis with EigenLayer

Mellow launched with backing from EigenLayer's ecosystem and integrated tightly with EigenLayer's architecture. The modular design means Mellow vaults can support not just EigenLayer but other restaking platforms as the ecosystem evolves, including Symbiotic, which emerged as a competitor in mid-2024.

Risks

Restaking is inherently complex and carries novel slashing risks that are not yet fully stress-tested. The modular LRT model means vault quality varies, poor operator selection by a vault creator could expose depositors to slashing. Mellow's role as infrastructure means it depends on the broader restaking ecosystem's success. If EigenLayer adoption plateaus, Mellow's TVL growth stalls.
