# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
