I want to get the staking balance and reward in Cardano. I am using the Blockfrost API and I can get the staking and reward amount using the stake address.
However, what I don't understand is that the staking address is not unique for each address. One staking address is associated with several wallet addresses. So, I can't get the exact stake and reward amount for a selected wallet. I can only get them for the selected stake address.
Could anyone explain this to me?
