ether.fi Stake vs Variational

Ether.fi offers non‑custodial liquid staking where users mint eETH while retaining full control of validator withdrawal credentials via a smart‑contract escrow. Validators are run by a professional operator marketplace, and any user can migrate their keys or exit to the beacon chain 1:1. Launched in March 2023, ether.fi holds over 800 k ETH and shares validator bribe rewards with stakers through the ETHfi governance token.
