Set up Cardano staking with the API

To set up staking on a Cardano ledger, you need to do the following:

Register a staking address.
Delegate staking to a stake pool.

You can also do the following:

Unregister a staking address.
Withdraw staking rewards: The accumulated rewards are automatically delegated. You can withdraw the rewards without affecting your staking amount, which still stays in the stake pool. However, you cannot withdraw rewards if the address does not have a minimum amount of non-rewarded currency.

System change process

All new requests to change the system state follow the same process. To familiarize yourself with this process first, see Manage intents and approvals.

To perform staking tasks on Cardano, follow the steps in Manage intents and approvals, with a payload similar to one of the following examples.
