Update delegation to a staking pool or passive delegation

You can change the delegation amount, target, and preferences on an account. You do not have to change all selections. For example, you might only want to change if rewards are restaked or not.

If you change the delegation, the new amount will be applied at the start of the next pay day. There is one pay day approximately every 24 hours. Note that if you decrease or remove the delegation, there is a cool-down period before the amount you’ve decreased the delegation by is returned to your disposable balance.

Before delegating stake to a staking pool, it is important to research the pool using CCDScan. You can only have one delegation per account.

Note

Any changes made in the last epoch before the upcoming pay day are applied not in the upcoming pay day but the pay day after that.

Note

All transfers and transactions cost a fee, including staking and unstaking transactions. The fee is based on the set NRG for that transaction and the current exchange rate. The cost of transaction fees is stable in Euros, and therefore the price in CCD varies depending on the CCD to EUR exchange rate. The fee will always be deducted from the Balance of the account, so it is important to have some available CCDs to cover fees. A locked-for-staking balance cannot be used to pay for these transactions. You can see the fee in the transaction log.

Warning

Make sure you have enough funds in your disposable balance to cover transaction fees.
