Think again if you didnt get a new seedphrase (maybe when you started using a Shelley wallet but didnt migrate your funds).
I think this is probably the most likely situation what happened.
If you dont have another seedphrase, im pretty out of ideas but wait for @HeptaSean , maybe he got another angle to tackle.
Much appreciated. It wasn’t a great sum that’s missing by any stretch ($500 CAN) but I’m sure I’d feel different if Ada ever spikes.
This somehow all doesn’t add up:
The one address you gave us doesn’t really look like an end user wallet address at all:
https://adastat.net/addresses/DdzFFzCqrhsxenNi511A45a4fq1WxeBJVzzJmoHLWr8BcJsdqnjEUQ2riVCmy1ssskaJo23tpi2NxpXiFimZS2o5WMPiyf3ckxJvKEdZ
It received ADA four times and every time exactly the same value was forwarded a (more or less) short time later to https://adastat.net/addresses/Ae2tdPwUPEZ6xYrxCgRDM2NQFM5oajHEoJN3i9ZVV2AbsbvxoJBjVu3yP7W (the three transactions already linked above and one two weeks earlier). And those transactions also collected ADA from a lot of other addresses. This is not about 500 CAD, these are tens of thousands of ADA.
So, to me it looks like that Ddz… address was the deposit address of an exchange – Coinbase or other – and that Ae2… address has been one of their main addresses for some time where the ADA from all the deposit addresses were collected.
Which leaves the question open: Do you have addresses of your wallet somewhere?
Here’s some screenshots of my original transactions (purchased on Coinbase and then sent them to external wallets based on advice from a coworker), plus two shots of wallets I sent them to. I believe I was using Guarda but the same coworker recommended a different wallet at some point.
The only place I have my wallet addresses was in the wallets I was using (copied and pasted directly from one wallet into another to send and receive and never shared them otherwise.)
This one went to a Shelley wallet that hasn’t been touched since that day – 2021-09-02:
https://adastat.net/accounts/c4d3b5e70a535e815094d03e450f2244c7a6cd346e9228084592d209
This could be a Daedalus wallet with 24 word seed phrase or a Yoroi wallet with 15 word seed phrase. Try all seed phrases that you have! You can try in any wallet app – Eternl, Typhon, Lace, … – they can all manage this wallet if you find the correct seed phrase.
This could be a chance to retrieve at least a part of your ADA.

This one did obviously go to the address you gave us. Seems to be this transaction:
https://adastat.net/transactions/b6cbc7381f1bc412e619de3ec110db3a35f204ea1e71d3e5be98c9e33e0fb617#outputs
(The difference between the 20.045603 ADA reported by Coinbase and the 19.865582 ADA arriving on the address can well be Coinbase’s fees.)
And also the third withdrawal on this list – 39.16 ADA on 2021-06-16 – fits well with this transaction:
https://adastat.net/transactions/3f30867ecd1cbc289db7448a0040580ad02d2537078f99b842cd526cf45c5ac6#outputs
38.983635 ADA arriving on that date.
As said: This is very surely not a Daedalus or Yoroi wallet.
What we can surely and without a doubt see on-chain is that whoever had the key to that address also had the keys to 70 other addresses to move >40k ADA elsewhere in this transaction:
https://adastat.net/transactions/d612af3e0e57fc5f8d1bb70adda67defcd6747eacb7723c14c06c654ccf4a99e
(And more addresses and even more ADA in other transactions.)
So, unless you had 40k ADA that we have never talked about in this thread, this address is not from your Daedalus or Yoroi wallets.
The address it all was consolidated on – https://adastat.net/addresses/Ae2tdPwUPEZ6xYrxCgRDM2NQFM5oajHEoJN3i9ZVV2AbsbvxoJBjVu3yP7W – does come up in some discussions:
This doesn’t have to mean that the address owner themselves has to be a scammer or so. It would also fit my guess that it is the address of an exchange where scammers had cashed out in those cases and where you have sent the ADA back then by accident.
Hard to find out after more than three years, but is there any chance you copied an address from somewhere else? The deposit address of Coinbase or another exchange you were using?
That one that hasn’t been touched since Sept of 2021 would be the one I’d most like to find then. I’ve been through all my recovery phrases and checked every wallet I’ve used in the past though and still coming up empty. I’ll keep searching and see if I find anything.
I’ve never owned 40k of ADA at any point so that wouldn’t be mine at all.
Thanks for all your help trying to assist me, you’re a true gentleman!
Did you ever use a hardware wallet? That would also be a possibility.
Just had a look here Address addr1q9jjr9axqxmm4a57pf6nyc6v402ggs9324yrdclke6wcezwy6w67wzjnt6q4p9xs8ezs7gjyc7nv6drwjg5qs3vj6gysj6me6g - Cardanoscan
There’s total of 405.949059 ADA under the Stake Key in two addresses Addresses - Cardanoscan
Does that look about right?
Give your seed phrase (mnemonic) a try in https://typhonwallet.io/
This wallet interface will show the total balance of all UTXOs (addresses) in the accounts under this seed phrase. It’s easier to understand, too.
Yep, that’s the one we were talking about:
Thanks, @HeptaSean 
I personally find cardanoscan.io the easier of our explorers to understand.
I use a hardware wallet (Ledger) for my XRP which is all safe and sound. My ADA I can’t find anywhere.
Did you at some point also use the Ledger for Cardano?
Have you tried if your ADA are maybe on the wallet connected with the Ledger?
I’ve attempted to restore any wallet I had that held ADA from the seed phrases that I copied down and still coming up empty.
No I never used it for ADA
Great work Sean and Fabian. Hope you guys can find the ADA.
