Simple, low cost staking for your Cardano Ada

A very low margin of 0.9%.

The stake pool infrastructure is deployed in the Amazon cloud to assist with high levels of reliability.

Supported by an experienced UK based team.

The Iron Pool has been successfully producing blocks and delivering rewards. The next rewards are due on the 28th of August.


Above is an example of our monitoring system for the pool, captured when Iron Pool first went live on the network.

We keep a detailed watch on our system as well as receiving automated notifications of potential problems.

It is critically important that any stake pool you delegate to has excellent up-time. The reason for this is if the stake pool is down at the random time it is chosen to produce the next block in the blockchain, all of the delegators to that pool will miss out on the Ada rewards for producing that block.


Simple, low fees.

A low margin of 0.9%. This means you keep 99.1% of the rewards. There are no plans to raise this.

The fixed fee of 340 Ada is the lowest level allowed by the network. This is charged every epoch (5 days), and is split across all of the members of the pool.


Is my delegated Ada safe in your pool?
Yes, due to the power of Cardano, when you delegate your Ada using Daedalus, it never actually leaves your wallet so it it not possible for you to lose your Ada to a stake pool.

Can I still spend my Ada once it has been delegated to your pool?
Yes, the Ada is still in your wallet and you can spend it as normal.

What is an epoch?
The Cardano network works in cycles of 5 days, each 5 day cycle is called an epoch.

What is cost per epoch?
This is not an upfront cost that you pay, it is a shared cost that comes out of the rewards of everyone in the pool.

At the end of an epoch, when the rewards for a whole pool are calculated, the cost per epoch is taken out of the pool's total combined rewards, and given to the pool operator.

This means that the larger the total Ada delegated to a pool (the controlled stake), the less that will be taken from your share of the rewards. Whereas if you were the only person in a pool, it would all come out of your rewards.

The Cardano network has set a minimum value for cost per epoch of 340 Ada, and this is the value most pools have chosen.

What is the margin?
Once the cost per epoch has been taken from the pool's combined rewards, a percentage of the pool's total rewards are then taken and given to the pool operator. This is the margin.

There is a large range in the margin values chosen across the different pools.

What is the pledge?
This acts as a boost factor for the rewards a pool receives/gives out.

e.g. if two pools have the exact same amount of total Ada delegated to them, with the exact same cost per epoch and margin, then the pool with the higher pledge will return slightly higher rewards.

Exactly how much more is complicated, and will in fact change over time. At the moment it makes surprisingly little difference how large a pledge is, but the Cardano network has declared that it will increase its impact over the longer term

What is the controlled stake?
This is the total Ada delegated to the pool. This is often expressed as a percentage of the total delegated stake across the whole Cardano network. This can be important as it effects how much of an impact the cost per epoch will have on your rewards.

The Daedalus wallet is currently showing 0 for all pools controlled stake. I assume this will be updated with correct values when the epoch ends shortly.
