ALTZ refunds you the fixed fee

Lifetime ROA (ALTZ):  %  (including fixed fee refund)
LIfetime ROA:   (according to Adapool data)

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.

Announcement: Continuing with our monthly returns of the fixed fee, the next refund will be sent on January, 26th. 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.

ALTZ commitment
  1. We are in Cardano since the beginning of 2018 and started our pool in the end of first month of ITN where we participated actively and supported the community of SPOs.
  2. Our pool is run and maintained by IT professional with more than 25 years of experience.
  3. We are small single pool and member of Cardano Single Pool Alliance (CSPA) that try to help decentralization and strengthen the health of Cardano network.
  4. ALTZ was one of the pools that produced block in the first epoch of Shelley mainnet.
  5. Our Pledge ratio is 1.9 and represent that we really have skin in the game and how much we are compromised with the project.
  6. We helped create awareness of Cardano and ADA adoption in the early days. One of the winners of Cardanopizza.
  7. 100% performance, we have never missed assigned blocks.
  8. As a small pool we have plenty of room for new delegators and there will be no danger of oversaturation.
  9. We have been one of the first pools (maybe the first one, epoch 253) giving back the 340 Fixed fee to delegators, so they have been getting the same ROA as in a big pool.
  10. We are donating 10% of our profit to Bulgarian organization which provides medical services to Street and abandoned dogs, shelters and feeds them and helps some of them to be adopted in Germany.
