MetaMask is an open-source wallet, active development happens on github. It is available as a browser extension and mobile app. But Portfolio MetaMask is not open source.
Given that even the MetaMask web site has a GitHub repository, it seems that the Portfolio is exceptional. Perhaps this should be flagged up much more clearly.
There are several reasons I wanted the source code.
As noted in Discover and display Aave debt tokens - #3 by rptb1 the Portfolio dapp doesn’t allow me to add an Aave debt token. In the Knowledge Base I found text saying that the Portfolio dapp has its own internal list of allowed tokens. Since the dapp is closed source, this list is effectively secret. I was interested in modifying the dapp to show Aave debt correctly and possibly submitting this back to the source.
(And of course all the usual reasons I want anything handling my money to be open source: auditing, public scrutiny, etc. etc.)
Submit a ticket through the contact button on the dapp. Please include these details you’ve shared, including the AAVE debt token not being able to be added, as well as the request for open source as well as anything else you want to include. This will be helpful for the team to discuss.
