Ticker change

Hi Friends,

I have the ticker name ADAPT.

ADAPT on pooltool.io

Back then, when I registered the pool with that ticker, I wasn’t aware that another pool already had the same name. For some reason it wasn’t showing in pools list even thought it was created before mine.

Now I’d like to change my ticker name by probably using one ₳ instead of a A.
Are unicode characters accepted?
I can see well performing pools with unicode characters (HODL₳) but I also read that ticker names must be made with [A-Z] [0-9] only.

Finally, can you please confirm that changing ticker name is as easy as modifying the pledge and won’t have impact on my very few delegators?

Appreciate your help!


should be accepted; But will be hard to find the pool in wallets by ticker…

Hi Stef, it is nearly as easy as changing your pledge or operator fee’s. It will just cost you only transaction fees. I have done it, changing my poolname from BR03K to SOON. Just adjust your metadatafile, recalculate the hash and submit your adjusted certificate(s) to the ledger. Like Alex said: just find a unique name between the about 1200 other pools! :sweat_smile: Unicode you just have to find out, got no experience with that.


Thanks @Alexd1985 @BR03K
I finally decided to change the ticker to a brand new one.

Enjoy the day!




I expereinced that the ticker does not change if you provide the same url.
Please prove me wrong!


How’s that?

After signing the transaction it did show up in
cardano-cli query ledger-state --testnet-magic 1097911063 --allegra-era | less
but then it was removed because I had already registered a different hass number with the same url.
Changing the url worked imediately.

To answer your question I do not know. I checked all possible errors I could have made, but I always can reproduce this error. Changing the url helps immediately.


I think u had another issue; I changed metadata manytimes without any problems

Yea metadata was never the problem only the ticker.
I think the issue is more subtle and could be some other issue. Maybe there is a chain of consecutive errors, which lead to this behavior. That is why I hope someone proofs me wrong. So you say when you have changed just your ticker everything was fine?
I have a test pool running as well so I might investigate it later again and report.

Hi @Johann_ADAholycs

Just to confirm I was able to successfully change the ticker using the same url.
Then, after my new website was up, I pushed again a new transaction to change the url only and it worked perfectly.
Where did you check if your new ticker was changed? on daedalus, the ledger.json and pooltool it is instant. On adapools, it can take up to 4 hours to observe the change. I know it can lead to confusions…
Enjoy the night!

Could some one please state the steps to change the ticker? Or correct my steps:

  1. Create the metadata.json file
  2. Hash the metadata.json file
  3. Create a tinyurl for the metadata.json file
  4. Re-create the registration certificate (? - not sure about it) with the new metadata.json
  5. Find balance & fees (but exclude the deposit fee - or? )
  6. Build, sign and send transaction



Create the metadata, upload it and sign the new registration certificate (without paying again 500ADA)

First tell me ur setup… coincashew or cntools?

thanks for responding.its coincashew

There’s a section about updating pool details on the Coincashew website: Updating Stake Pool Information - CoinCashew

Then create a new certificate using the step from coincashew provided by @mcrio

@Alexd1985 @mcrio thank you my friends . i checked it out. please correct me if i am wrong. so the only thing which is deleted from the commands of this section to reregister the stake pool with new data is ${stakePoolDeposit})) , this ${stakePoolDeposit})) is what we dont pay (that 500 adas) when reregistering the pool data?

Yes, you deposit 500ADA just once. The commands on the page above do not include any deposit data related parameters. You just need to cover the transacion fee when submitting the new certificate.
