All 1PCT Pools Are Identical In Fees And Performance. – Over Time

Verify Our Performance

Staking your ADA is about securing the Cardano network, and earning rewards for doing so. We charge the smallest fee of 1% to “keep the pools producing at the highest performance” and then pass 99% of the rewards onto you.

With our 6.3 million ADA pledge, stakers know we have “skin-in-the-game” and are operating at scale to pass the savings on to you.

Join the holders of 1.1 Billion ADA who trust us with their rewards.

We look forward to rewarding the most ADA into
your wallet.

OK, How Do I Stake With You ?

1 Step


Install Application

In order to stake your ADA, you first need a wallet. The official wallets are Daedalus and Yoroi. Daedalus is the most secure of the two, and it’s a full node wallet. This means that it downloads the whole chain, and validates every block. Yoroi is available as a browser plugin, and as a mobile app. It’s a light wallet, which means it relies on a third-party to validate the chain.

We look forward to rewarding the most ADA into your wallet.

2 Step

Create Wallet

Create Your Wallet

Once you have Daedalus or Yoroi installed, you need to create your wallet. You will be guided through this inside the program. Remember to write down your 24 recovery words and keep them safe! If you’re using Daedalus, it will now download and verify the blockchain. You should now send all your ADA to your wallet. You should look for the receiving addresses associated with your wallet, and simply select one of them. When your ADA is transferred, you click the following symbol to go to the Delegation Center (Daedalus).

You then need to click on the Stake Pools Tabs, and
write "I percent pool" in the search field.

All 1PCT pools will now be shown simply click on The one with the lowest saturation (latest filled bar ) and then click "Delegate to this pool".

Simply follow the on-screen guide, that will take you through the rest of the delegation

Our Advantages

Quick Facts About Staking In 1 Percent Pool
  1. Your ADA is never locked. You can always send it somewhere else.
  2. Your ADA stays in your wallet, fully under your own control.
  3. You do not risk your ADA by staking it.
  4. The protocol charges a 2 ADA stake key deposit the first time you delegate your ADA. This is the same for all pools.
  5. It takes 3-4 epochs for your first rewards to show up. That is 15-20 days. This is the same for all pools.
  6. After the initial 3-4 epochs, you will receive your rewards every epoch (5 days).

7. You can freely change your delegation to another 1PCT pool. You will still get rewards every epoch if you change the pool.

8. Your rewards are automatically staked as well. There is no need to withdraw rewards every epoch.

9. You can simply add more ada to your wallet, and it will automatically be staked as well.

10. Rewards amount will naturally fluctuate from epoch to epoch. It’s part of how the protocol is built, and it’s the same for all pools.

Our Pools

 Select the 1PCT pool with the lowest saturation. This way you avoid getting oversaturated. Pools staked with up to 64M ADA are good, but going above will slightly decrease your rewards. All our pools have identical fees and performance – over time.

When Do I Get My Rewards ?

 An example of the ADA Rewards schedule  :

Epoch 270:
Epoch 271:
Epoch 272:
Epoch 273:
Epoch 274:

In this example, you should see the first rewards in the beginning of Epoch 274. The payment schedule is the same for all pools on Cardano, as the payment of rewards is handled 100% by the protocol itself. Pool operators have zero influence on the payments – we simply make the blocks, and the protocol does the rest.In this example, you should see the first rewards in the beginning of Epoch 274.

Pool Parameters


Cardano implemented a minimum pool cost of 340 ADA. There is no way around this for any stake pool. This amount is subtracted from the total pool rewards after each epoch (5 days on mainnet), and then the rewards are divided between the delegators.

All the 1PCT pools have 225,000 ADA pledged to them.


If the total pool rewards for an epoch is 50.000 ADA, we first subtract 340 ADA as the pool cost. That leaves 49.660 ADA as rewards. Based on these 49.660 ADA, the pool takes 1% (496,6 ADA) and the rest of the rewards (49.163,4 ADA) are then distributed to the delegators. The total pool rewards for an epoch depends on the saturation level of the pool.

What Is Saturation

Currently, each pool has a ~64M delegation limit or “saturation”.   Once a pool is fully saturated, you can still delegate to it, but it will not earn more rewards for it. The rewards will simply be shared between more delegators, hence giving you less rewards. Always delegate to the 1PCT pool with the lowest saturation.

Pledged 6.3M ADA

July 2021: We have 1.1B ADA staked by the community. Join the thousands of ADA holders that trust us for max rewards

1 Percent Pool was started in the beginning of the ITN, and has always been a top performing pool. We have over 18 months of proven reliability, and our team is located on 3 continents in order to provide max performance. 1PCT is a bit different. We maintain an enterprise-grade system that stakes +2 Billion USD. The concept is very simple: We provide best-in-class stake pool performance at a very good price point. Alternatively, if you choose a bad pool, many things can go wrong. The pool could fail, blocks be missed or it could completely go out of business. This means missing out on your staking rewards. The operator could increase the fees without you noticing, which means less rewards for you. The best rewards are found when selecting a pool that has strong pledge, top performance data and the smallest fee on PoolTool.io. With 1 Percent Pool you can just set-it-and-forget-it. When you come back 12 months from now, all your rewards will be there waiting for you

Part of the security setup of 1 Percent Pool is staying anonymous. It’s much harder to attack someone, when you don’t know who they are.

Verify our pledge of 6.3M ADA. This keeps 1PCT honest, incentivized and producing rewards for you.

We believe in free markets, decentralization and meritocracy. Ie: trusting the code — and not our identity.

Moreover, with a global team distributed on 3 continents, our ability to ensure uptime 24/7 sets us apart from smaller pools.

Ever since 2017, we’ve had an immense love for Cardano. What the project is achieving is very inspiring and worth building for.

In support of : “decentralization parameter D=0”, you can expect our releases of education and tools via the Why Cardano Show (YouTube) starting April 2021.

ITN stands for Incenticized Test Net. It was 6 months of test net for Shelley, that was designed to test the game theory and incentive scheme. It started in December 2019. Many pools operators gained valuable experience in running a pool there, and established a reputation. The rewards from the test net were transferred to the main net, which made the test net incentivized – you earned real money from staking on the test net.

Pledge is the amount of ADA a stake pool has guaranteed to keep in its account. It’s a way of proving to the delegators that the stake pool is serious and has ‘skin in the game’. High ADA pledge helps keep stake pool operators honest. The average stake pool has ~22,000 ADA pledged.

All 1PCT Pools have a pledge of 225.000 ADA each. (*10X greater than the average pool operator)

It sounds tempting to go for the lowest possible fee, but just like very cheap items on eBay, it’s rarely worth it.

In order for a stake pool to generate the maximum rewards over time, you need a professional and sophisticated setup. You need to make sure that the pools are highly connected to the network, that the hardware is adequate, that the internet connection is optimal, that the software is configured correctly and that the pool software is updated frequently. You need to build redundancy and automation, to have multiple internet connections, to have UPS backup power for the hardware and protect against attacks. You need a high level of automation and monitoring, to always keep the pools running perfectly, and in case of any breakdown, have a backup server standing by, that will automatically take over.

The income from a 0% pool is simply not enough to cover the expense of the above mentioned setup. For this reason, the 0% pools do not have this kind of setup, but instead run a much simpler operation. This means that they will perform worse over time, and hence pay less rewards. If you do the math, a 0% pool will give you worse rewards, even though it looks better on paper.

You risk having the pool operator raise the fees after they’ve attracted enough stake, or having the pool simply shut down because it’s not profitable. You don’t want to constantly have to check if the pool is still at 0% fee and still running, and risk staking to a dead pool or suddenly paying a much higher fee.

Pools with 0% fee are furthermore not incentivised to perform their best. The operator only makes money from the first block each epoch, and he then has no incentive to keep the pools performing well. There is no reason for him to make sure the rewards are at the absolute max, since it means extra costs for him, but no extra income. A pool with 1% fee has a great incentive to make sure the pools are always at their very max performance, and is willing to invest in it.

1 Percent Pool is operating 28 pools in total. The tickers are 1PCT, 1PCT0, 1PCT1, 1PCT2, 1PCT3, 1PCT4, 1PCT5, 1PCT6, 1PCT7, 1PCT8 and 1PCT9.

There are a v1, v2 and v3 of each of these tickers.

Since you cannot own a ticker in a decentralised network, it’s possible for anyone to try and imitate the 1PCT brand. These attempts are usually quickly filtered in the metadata services. You can verify that the pools are authentic 1 Percent Pools by comparing the pool id from our pool list with the pool id inside Daedalus / Yoroi / AdaLite. Currently, if using PoolTool.io: If a pool has 1PCT + green check mark this is a valid 1PCT pool

Cardano does so many things right, and is built on a solid foundation of research and scientific rigor. It’s fantastic when it comes to hard science, but it’s different when it comes to soft science. You can not create a mathematical proof when it comes to the game theory that shapes the human incentives for actions. Since Cardano is highly dependent on delegators acting rationally, this becomes one of the key risk areas for the survival of Cardano.

For Cardano to stay secure, we need:

– Informed delegators who knows about the concepts of fee, saturation, rewards, pledge and so forth.

– Rational delegators whose actions you can mostly predict, based on human nature. You can only have this, if they are informed.

– Protocol parameters that favour true decentralisation, and helps protect against Sybil attacks.

Since 2017, I have personally been most worried about the game theory around the decentralisation of the protocol. What would stop an entity from creating 1000 pools, get a majority of the stake by having no fees at all, and then start censoring the network? Since this, in my eyes, was the greatest threat to the project, it had to be given more focus.

When the ITN launched, I set out to test how delegators would react to an entity that openly created a large number of pools with very low fees. Since it was a test net, there would be no major harm to the network, but there would be immense learnings and opportunities to adjust the game theory model to secure the network properly. In the beginning, I simply acted like any smart Sybil attacker would do, if they tried to gain a majority of the stake. The first 11 pools were filled within weeks.

At the time, the Cardano Foundation was the gate keepers of the tickers, and had to approve a ticker in order for it to show up in Daedalus. When I tried to further test the vulnerability of the network, I was made aware of that the ITN was not tuned for Sybil attack resistance at all, which defeated the whole purpose of trying. I couldn’t perform an accurate test, because none of it was implemented. Hence I dropped the idea of trying to accumulate more stake, and focused on the performance of the pools instead.

The experiment did show how delegators could easily be attracted by low fees, but there is another major factor to look at, before judging the experiment. At the beginning of the ITN, the software was very shaky, and often failed. It was being built as a whole separate codebase, that allowed for quick iterations and development, so we could test the incentive schemes before main net. This meant that it was far from a level playing field for the operators. The first weeks and months were all about writing smart scripts to restart the software at the right times, to make sure it could actually make a block once it was time. 1 Percent Pool had a huge edge here, as I had figured out a number of rules that would make it perform very well, despite all the bugs. It involved a lot of monitoring, restarting each node 15 minutes before a block, a “private” bootstrap cluster to make the software start quickly and much, much more.

Since 1 Percent Pool was one of the very few great performing pools in the beginning, it was very natural that delegators rushed into the pools. The same would have happened if the fees were at 5%. For this reason, the test was not really accurate at all. Thankfully, the software we have on main net now is very stable and it’s (almost) a completely level playing field. It didn’t make sense to share the restart scripts with the community at the time, since it would work against the Sybil experiment, and once the experiment was dropped, many of the bugs had been ironed out. I did however share an article about how to improve the bootstrap time for the nodes and optimise the performance, which can be found here.

1 Percent Pool is now no longer an experiment, but an active protector of the protocol. It makes it much harder for a bad actor to try and perform a Sybil attack, and in these early days, we make sure that a lot of the stake is secure with a good actor. Once we see a higher number of reputable pools in the months and years to come, the network will be less at risk.

The focus of the pool, apart from best-in-class performance and low fees, is to study and prevent the possibility of Sybil attacks. We’re actively working with IOG/IOHK on this issue and sharing ideas, in order to further harden the resistance of such attacks. This is our way of contributing to the community and protocol.

Yes! We are fortunate to have the largest public stake delegated to us and respond by having an enterprise-grade solution located in 3 countries.

When working with large financial institutions staking ADA, having an Amazon Web Services setup for $99/month is simply not an option.

Every 7 days we produce ~1 million ADA for our stakers.
In order to guarantee this reward output, we provide the most fault-resistant staking in Cardano. We only use dedicated servers in Tier 4 data centers.

These servers are the fastest on the market. Unfortunately, the economics of a small stake pool, do not allow for this infrastructure expense.

Lastly, we also run secondary and tertiary systems in different continents to serve as backup, in case of a primary data center failure.

This is how we are able to produce more blocks than any other pool group. This is why +1B ADA stakes with us.

We don’t use socials. The contact form at the bottom of this page is the fastest way to get in touch for staking-related matters. 

Yes! There are many good actors in the space, with different models and participation efforts. If you are not into the 1 Percent Pool concept, you should take a look at WEQNT, FROG, ATADA, LOVE, ANP, CRDNS, DIGI, SCAR, BCSH and PEGA (just to name a few). There are many other great operators out there.
There are many factors you should look out for, that indicates that a pool isn’t the best choice. Among these are: -Pools with 0% fee (discussed in “Why should I not select a 0% pool” above) -Pools with pledge below 50k ADA (Signals that without real-capital-at-stake, they might not be serious about their operation, or have confidence in themselves.). -Pools that haven’t produced blocks yet (They might simply be new, but this can be a sign of poor performance). -Pools without a website or option to contact them (Signals they might not run a serious operation)
