Since staking became very popular after the public sale I collected a few connected topics:
(1) To see the staking rewards use the blockchain explorer https://centrifuge.subscan.io/ and enter your Centrifuge address. The rewards are shown in the category “Reward&slash”.
Note: the value of the rewards and the frequency are not always the same and vary from validator to validator. Staking rewards are not paid out immediately (it takes about 24 hrs)
(2) The staking APY for different validators can be found at
https://portal.chain.centrifuge.io/#/staking/targets
(3) Here is an interesting article about “oversubscribed validators”, how to identify them and why it is important to avoid them (if possible):
