What is the minimum (lowest) amount of Ada needed to stake?

Could you have the delegation fee + 0.00001 Ada? Where is this referenced?

There is an initial 2.17 ADA fee when delegating a wallet for the first time.

Here's the breakdown of that: 2 ADA deposit goes towards registering your stake address on the blockchain and ~0.17 ADA is the transaction fee.

Note: the 2 ADA deposit is refundable upon unstaking

Happy staking!

The 2 ADA (current configuration of "keyDeposit") comes from the mainnet genesis file.

    This is great. Do you know the source of info for this, in the specs?

There is no staking minimum, but there is a UTXO minimum. With current protocol parameters, any UTXO on Cardano must have a minimum of 1 ADA (minUTXOvalue).

So while possible in principle, there is currently no way to create a UTXO, and thus to stake, anything less than 1 ADA.

  • Thanks. I helped onboard a friend to setup a Cardano wallet, had 2.83 Ada in there, had him setup staking. The .833 Ada delegation fee went thru, however the 2 Ada never appeared back in his wallet, although on the blockchain the transaction went thru. I opened up a ticket in ccvault wallet to perhaps fix this display or add a warning. github.com/ccwalletio/tracker/issues/68

  • Just to be clear - the staking certificate (delegation) fee is 2 ADA. Whatever is leftover in the wallet will then be staked, plus whatever you add to the wallet. If you'd like to receive the 2 ADA back you would have to de-register your staking key. Think of the 2 ADA as a deposit for staking that you will get back if you choose to unstake.
