Mellow Protocol

Mellow Protocol receives a B- risk grade (29/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — permissionless vault creation and untested slashing mechanics introduce meaningful uncertainty despite solid architecture A restaking platform that lets anyone create vaults where users deposit ETH to earn extra yield from securing other networks through Symbiotic. It manages $310M in deposits. Its B- grade reflects a solid design with meaningful risks from untested slashing penalties and the fact that anyone can create vaults, with only curators standing between you and a bad one.

The key risks identified for Mellow Protocol are: (1) If a service secured by Symbiotic fails, multiple Mellow vaults could be penalized simultaneously. Users in all affected vaults lose 10-30% of their deposit, not just those directly exposed. (2) Anyone can create a vault. Curators are supposed to filter out bad ones, but curators could be bribed, negligent, or socially manipulated into approving a trap vault. (3) Withdrawing your ETH takes 7 days. During a crisis, early exiters get out while later ones face growing losses as the secondary market price crashes below the actual value.
