If you're looking to join a nomination pool on Polkadot or Kusama, this article may help you choose the pool that's right for you.


Nomination pools are designed to permissionlessly allow members to pool their funds together and act as a single nominator account. The minimum to join a nomination pool and earn rewards is low: just 1 DOT on Polkadot or 0.00166666665 KSM on Kusama. You can read more about nomination pools in this article.


It is important to do your own research before joining a nomination pool. When you join a pool, your funds remain in your custody; however, you trust the pool administration to use them to nominate in your interest. If the pool is not managed effectively, you may not be earning the rewards you expected. The pool administration's choice of validators can lead to slashing, and you and other pool members may lose funds.


‼️ IMPORTANT

Please remember that to switch a nomination pool, you need to unbond first. The unbonding period is 28 days on Polkadot and 7 days on Kusama. During the unbonding period, you are not earning rewards. So, make sure to choose a nomination pool you'll be happy with.


If you want to have more control of your nominations and monitor them yourself, you can stake solo, but remember that the minimum stake to earn rewards in much higher in that case:

What You Can Learn About a Pool On-Chain


The following information about a nomination pool can be found on the Staking Dashboard and block explorers.


Pool Commission


Nomination pools can charge a commission. It is applied to the staking rewards the pool earned after the validators took their commission. On Polkadot and Kusama, a pool commission can be anywhere between 0% and 10%. If a pool has a non-zero percent commission, you will see it on the Staking Dashboard:


Pool administration can change this commission over time. You can read more about pool commissions here.


Current Pool Nominations


To see all the validators the nomination pool currently nominates, click on the menu button next to the pool, and choose "View Pool Nominations":


Make sure you agree with the choice the pool administration made. It's recommended to avoid nominating validators with 100% commission. You can check other points to consider in this article.


Total Stake


You can see the pool's total stake under its name. Make sure it's well above the current minimum amount required to earn rewards. You can see the minimum on the Nominate page:


Please note that this minimum is dynamic and will change over time, as well as the pool's total stake.


Pool Administration Accounts


You can copy the nomination pool's address from the Staking Dashboard:



Then you can use block explorers to see which accounts manage the pool. There are several roles in a nomination pool administration; you can learn more about them here.


Here are a few things to consider about the accounts that manage the pool:

  • Is the same personal account playing all roles, or are there different accounts in the pool administration? Having one personal account for every role may be convenient for the owner, but it also creates a single point of failure. If the only pool manager loses access to their account or just loses their interest, the pool will be left unattended.
  • Is it a personal account that manages the pool, or a multi-signature one? Multi-signature accounts are controlled by several key owners, not just one, and are a good solution for teams that want to manage a pool collectively.
  • Do the management accounts have on-chain identities with contact information? You may want to talk to the pool manager, e.g., to ask some questions about the pool. Having their contact information will be very helpful in this case.


Pool's Contact Information


Nomination pools don't have on-chain identities with contact information. However, you can sometimes find the pool's website or social media account information in its name. You may need to check the pool on a block explorer to see its full name. On the pool's website or social media, you may find answers to your "off-chain" questions, which we will cover below, or get in touch with the pool management.


What You Can Learn About a Pool Off-Chain


Some questions about how a nomination pool is managed can't be answered from the on-chain information alone. You may need to talk to the pool management or check the pool's website or social media.


Permissionless Rewards Claiming


Pool members can allow permissionless claiming of their rewards (to their account, to their stake in the pool, or both). Some nomination pools claim rewards for their members as part of their services, allowing members to compound the rewards without paying transaction fees or monitoring the situation. The more often your rewards are compounded, the more effect it has on your total rewards earned.


Nomination Adjustment


Nomination pools nominate validators for all members of the pool based on some criteria, like the ones described in this article. Over time, the selected validators can raise their commission, make significant changes to their infrastructure, or even stop validating. The pool administration should review the pool's nominations and adjust them from time to time. You may want to see how often the nominations are changed and on what criteria.


Community Reputation


Nomination pool administrators can be active on their social media and in the ecosystem channels to answer potential questions, attract new members, and boost their reputation. You can join the Polkadot community on social media to see what reputation a nomination pool has.
