# Choose validator

In order to choose validators, delegators have to access KardiaChain explorer. Information about the validator that delegators should care includes:

* Commission rate: the commission rate on revenue charged to any delegator by the validator. 
* Commission max change rate: the maximum daily increase of the validator  commission.
* Maximum commission: the maximum commission rate this validator can charge. This parameter can not be changed by the validator.
* Minimum self-delegation: the minimum amount of KAI the validator needs to have bonded all time. If the validator’s self-delegation is below this limit, their stake pool will be unbound.

Additionally, delegators should care about the reputation of the validator, access the validator’s website, and validator's description to stake a validator candidate that they trust to help them earn rewards.
