Ankr is a decentralized infrastructure provider helping users stake assets to secure different blockchains.
Ankr allows users to earn staking rewards without locking assets or maintaining staking infrastructure. Users deposit their PoS assets into Ankr's smart contracts and receive reward-earning or reward-bearing tokens in return, representing the value of the user's staked assets along with any staking rewards accrued or penalties inflicted on the validators. Reward earning tokens (aka rebase tokens) represent the underlying staked assets. These tokens have an elastic supply as rewards occur through the rebasing process where more tokens are continuously issued to the staker's wallet, which serves to increase the number of tokens without changing the price. Reward-bearing tokens represent the staked asset plus all accrued staking rewards. These tokens accrue value rather than increasing the token supply. Users can withdraw or redeem their liquid staking assets back for their original PoS assets at any time, following an unbonding period.
Ankr generates revenue by charging a 2-10% fee on the staking rewards earned by depositors. This fee varies depending on each PoS network. For example, AVAX staking incurs a 2% fee, BNB staking incurs a 5% fee, and ETH staking charges a 10% fee (earned by Ankr's validator node).
Passive holders can generate additional yield by participating in the PoS validation mechanism to earn block rewards. The unlocked liquidity with reward-bearing or reward-earning tokens can also be used on a number of popular DeFi protocols to generate additional yield.
