Understanding a stake transaction

[Matti7887]

Hello Everyone,

can someone please help me to understand a staking transaction?

If i look at this transaction:
https://explorer.cardano.org/en/transaction?id=348060a79ad1db439937c3d6af8705ea71da5e87cc6854a0cf48e483d4fb3766

There is 282.534747 ADA input and 280.36049 ADA output but only 0.174257 ADA as fee.
Where did the 2 ADA go?

Best regards,

Matti

Haven’t checked the math but there’s a 2 ADA refundable registration fee.

[Matti7887]

For what is that registration fee? For staking to a pool? And what means refundable?
Could you please explain that a bit more?

Thanks and best regards,
Matti

For delegation, yes, and you get it back if/when delegation ends (in most cases it will be reused when you change delegation to a different pool).

Thanks for your help RobJF.
With your hint i found that post and now i understand:

Output and Transaction Fee

I staked or delegated my ADA and when I look at the transaction ID it says all of my larger amount of ADA as output, and the smaller amount is 0.174433 ADA transaction fee. When I look at Daedalus it says that I sent 2.17443 ADA. I just wanted to make sure I didn’t send all of my ADA to the guy at the address. I guess I’m confused about all of this. Can anyone reassure me I didn’t make a big mistake? Thanks!

In fact its 2 ADA what iam missing in that transaction and thats the KeyDeposit. Didnt got the math right in the first post.

Thanks a lot!

Best regards,
Matti
