1. Can I add additional keys to the pool’s metadata? Will it become invalid if I add custom keys?

2. Are there any additional supported keys in addition to:

- name
- description
- ticker
- homepage

I saw that file. But are those additional keys official and can be used later i.e. in Daedalus or are they used for Adapools only?

</div>

in case you were still wondering, you need to add extended to the end of your pool metadata .json the created a new .json, the url should reference that new .json location

example  
{  
“name”: “Stakepool Name Here”,  
“description”: “ ~~~~~~ ”,  
“ticker”: “EXPL”,  
“homepage”: “[https://yoururl.com](https://yoururl.com)”,  
“extended”: “[https://yoururl.com](https://yoururl.com)”  
}

@KrakenStaking do we need to create new pool.cert after adding extended section to the poolMetaData.json?

you should not have to, mine setup has been fine since adding the extended data which was 4 days or so ago (at least it appears to be okay, haha).

Hi, could you update the metadata then without recreate the pool.cert? I have my metadata on github, so can i add there just the extended metadata Info?

Correct, you can just tack it on, as long as your pool cert was submitted with the main branch url and not the specific version of the .json on github

No need to recreate pool.cert. I can confirm that the @KrakenStaking way is working correctly.

I simplified; but question . Did u registered the pool after u added extended url inside metadata file?

```auto

I’m curious how this works without regenerating the cert - surely the hash of the file in the cert/on-chain no longer matches if you modify the file to add the extend URL afterwards?
