Yes — there is a user guide (opens in a new tab).
No, you can stake at your discretion, unlimited.
You receive the unstaked DOT after the unbonding period of up to 28 days.
aDOTb is a rebasing token. When holding aDOTb, your balance will increase in proportion to your DOT staking rewards. A rebase runs daily, and rewards occur each time this runs. So each day, you will see the quantity of your aDOTb increase by a small amount.
aDOTb will increase with every rebase; rebasing occurs daily.
Ankr takes a 2% technical service fee from the staking reward to cover for the provided services and operations.
Staking rewards depend mostly on the voting power of the validator node that your stake is delegated to. Ankr aims to spread delegations to only the most trustworthy and reliable nodes to increase staking rewards.
Your stake immediately stops accumulating rewards once you clicked Unstake.
The only risk for stakers is missing out on rewards during any time a validator they staked with is slashed. Slashing is a protocol-level penalty associated with a validator failure if it validates an invalid transaction, attacks the network, or goes offline. The delegated staked DOT is not slashed — slashing impacts only the self-stake of the validator. Ankr only delegates to trusted and reputable validator nodes to avoid any validator that would act maliciously.

Rewards accumulate in aDOTb. As it is a rebasing token, its quantity grows each day in your wallet to reflect the amount of DOT you will get when you unstake. For example, you have staked 100 DOT and claimed 100 aDOTb for it. Your aDOTb balance grows overtime and at a certain point reaches 110 aDOTb — you will get 110 DOT if you unstake then.
