XTZ Black – Terms and Conditions

Tezos disclaimer

The Tezos network is experimental software. It should not be used for high value or important transactions.

Disclaimer of warranties and limitation of liability

The XTZ Black services and all information, content and materials included on or otherwise made available to you through XTZ Black are provided by XTZ Black on an “as is” and “as available” basis. XTZ Black makes no representations or warranties of any kind, express or implied, as to the operation of XTZ Black services, or the information, content and materials included on or otherwise made available to you through XTZ Black. You expressly agree that your use of XTZ Black services is at your sole risk.


  • In order to delegate to XTZ Black, first check that our delegation status is set to ‘open’ on our homepage, then simply set your delegate to our baking address:


  • The minimum delegation amount is currently 2,500 XTZ, no rewards will be paid to delegations below this threshold
  • You will not be allocated /paid any rewards if you delegate to us whilst our status is set to ‘Closed’.


  • XTZ Black will deduct a 5% baking fee from the gross baking rewards (including endorsements, etc) allocated to us by the Tezos network.
  • There is currently no transaction fee for reward payments made to delegates, however if transaction fees become necessary due to network congestion these will be deducted from the delegate reward payment.

Calculation of baking rewards

  • The rewards payment will be calculated in line with TzScan (minimum delegation threshold still applies).
  • A Snapshot of delegate balances will be taken at a random point within each cycle for the purposes of calculating rewards share. If you increase your delegation amount in a given cycle, this may not be captured until the next cycle.
  • Baking rights are backdated by 7 cycles, meaning if you delegated to us in cycle 0, we would receive your baking rights in cycle 7.
  • Baking rewards are locked by the Tezos network for 5 cycles after being earnt.
  • Baking rewards are accumulated 13 cycles in arrears, meaning if you delegated in cycle 0, you start accumulating baking rewards in cycle 13.

Payment of baking rewards

Baking rewards will be paid automatically to all delegates every five cycles starting from cycle 10.

Reward re-investment

We do not offer the facility to ‘re-invest’ baking rewards. If you wish to do this, you should increase your delegation amount. Baking rewards will accumulate only on delegated balances, not pending rewards payments.

Changing delegation amount

You may increase or decrease the amount of XTZ you delegate to XTZ Black at any time. The minimum delegation threshold still applies, if your delegation amount drops below the minimum threshold, you will not accumulate rewards until your balance is increased above the threshold.

Over delegation

In the event of the service becoming over delegated (i.e. XTZ Black does not have enough security bonds to cover the requirements for the XTZ delegated to us) we will endeavour to mitigate this. However we can not guarantee that rewards will not be diluted due to the surplus delegated balances.

Leaving us

If you delegate to another provider, we will pay rewards accumulated by you until your baking rights transfer from us.

Variation of terms

XTZ Black may modify these terms and conditions at any time. Notice will be given via the service update page.

Service updates

It is your responsibility to check the website regularly for service updates including updates to terms and conditions, announcement of reward payouts and any other relevant publications.
