Ankr’s Validator Hub is a module on the Ethereum Network that simplifies delegated staking. This comprehensive guide delves into the core components of Ankr’s staking ecosystem, such as its innovative staking modes, the roles of node providers and validators, and the streamlined rewards and unstaking processes.


  • Ankr provides two staking modes: node staking for direct Ethereum delegating and vNFT staking for added flexibility using non-fungible tokens to represent validator membership
  • Rewards are distributed on a regular basis, and the unstaking process is straightforward, allowing for quick access to funds and accumulated rewards
  • Registered legal entities on Ankr's platform offer reliable staking services, including multiple validators and customizable insurance policies
  • Ankr's Validator Hub caters to both experienced and new stakers, making Ethereum staking easy and rewarding

Validator Hub: How does it work?

The Validator Hub is built on a robust architecture comprising smart contracts, a backend, and a frontend. These components collectively manage staking, validator selection, MEV & tip distribution, and more. Users are required to stake a minimum of 32 ETH per validator, choosing from the listed node providers. Several smart contracts govern various aspects, including staking, unstaking, rewards, and the creation of vNFTs.

Once users choose a node provider and stake their ETH, Ankr then deposits the funds into a validator associated with that provider, initiating the activation process and subsequent reward generation for the user.

Staking Modes

Ankr provides users with two distinct staking modes:

  • Node Staking: Users can directly stake their Ethereum with a chosen node provider, participating in the staking process and earning rewards. Node Staking rewards are sent to the user's withdrawal address approximately every seven days.

  • vNFT Staking: Users opting for this mode receive a non-fungible token (vNFT) as proof of validator ownership. The vNFT can be used in decentralized finance (DeFi) activities, offering transferability without an unbounding period. Once users decide to unstake, the tokens will be available immediately.

vNFT Staking offers the same staking benefits as Node Staking but with added flexibility. It involves attestation rewards and a portion of the MEV (Maximal Extractable Value) & tips accumulating in the vStaker contract.

Unstaking Process

For Node Staking, the unstaked amount and rewards are released to the withdrawal address after an average unbonding period of 5 days, with MEV & tips released instantly. Similarly, vNFT Unstaking is akin to Node Unstaking, with the assets claimed from the vStaker contract associated with the vNFT.

Claiming rewards, including MEV & tips and attestation rewards, is facilitated through specific mechanisms for both staking methods.

Node Providers and Validators

Within the Validator Hub, Node Providers and Validators play a pivotal role. These legal entities registered on the platform offer users staking services. Node Providers can host multiple validators, set their own insurance policies, and earn fees derived from Maximal Extractable Value (MEV) and tips, serving as financial incentives for their services.

Bringing Versatile and Robust Staking to the Masses

Ankr's Validator Hub presents a compelling solution for those looking to engage in delegated staking on the Ethereum network. With its diverse staking modes, unique rewards structure, and robust architecture, Ankr continues to solidify its position as a leading player in the Web3 infrastructure space.

Whether you're a seasoned staker or a newcomer to the blockchain scene, Ankr's staking hubs offer a user-friendly and rewarding experience worth exploring.
