No 340 fixed fee!!!

Cardano decentralization is a value, a necessity and must be a reality.
Start staking with us and we will give you back the part of the 340 fixed fee that correspond to your stake's percentage in ALTZ
Fixed fee is a barrier for delegating in SMALL SINGLE POOLS (the ones which fully represent decentralization).
ALTZ wants to contribute to decentralization getting rid of this fix fee and you'll have the same ROS as in a big stake pool. We will send your part to your reward address when it accumulates at least 5 ₳. Please, give it a try, help decentralization and contribute to the health of the Cardano network.

'No 340 fixed fee' is a reality with ALTZ. So far, we have refunded more than 750 ₳ to our delegators, automatically increasing their rentability with our pool.

Please if you have any questions do not hesitate to contact us.

You can find your rewards, including the fixed fee refunds at Delegator Area.

Current Alonzo mainnet epoch   290

Remaining time in this epoch (according our BP node),


-  Lifetime minted blocks:
-  Epoch Blocks: 
-  ROA (lifetime): 
-  ROA (ALTZ)* 2.196 %


(*)ROA includes refund of fixed fee for epoch 288

Pledge, 1 million ₳

Until Q3 of 2021 the benefits of higher 'pledge' amount are not crucial for our delegators. So we have decided to keep a pledging of 1 million ₳.


We are among stake pools minting blocks at the first epoch (211) when decentralization begun to work. We are really proud of our delegators and, thanks them,  we minted our first Shelley mainnet block and all the rest of following blocks.

CardanoTM stake pool ALTZ

We are excited to participate in Cardano, a Cutting-edge technology Project, by supporting its network from the beginning of ITN with our Stake Pools. Our goal is to help Cardano community grows and provide it with our Excellent, Stable and Secure Staking Services:

  • High return to our delegators (no saturation)
  • 100% Performance (minted blocks vs. assigned)
  • 24/7/365 site monitoring


An adequate cloud infrastructure, 24/7 monitoring systems and our high performance platform establish an important base for the professional staking task at the new decentralized cardano environment.
Our network topology allow us to get optimum propagation times. <500ms of average propagation delay producer and receiver time.
100% of assigned blocks are currently minted because our delegators investment is our main worry, focussing all our efforts.
