This is a Bisq Network proposal. Please familiarize yourself with the submission and review process.

Grin has been used in Bisq from the day when it started but had been deactivated due technical problems and the missing tool for verify the transaction (similar to Monero tx key tool).

Those problems have been fixed in the meantime and the tools are available since long.
The Grin community has reached out several times requesting Bisq to re-enable it again. Due lack of dev resources on Bisq side that has not been taken care of.
Now there is another approach to resolve that old hanging issue.
Here is the actual discussions about it:
bisq-network/growth#205

There has been brought up the point that Bisq had stopped adding Altcoins and it requires a DAO vote to make an exception from that. It is a unclear situation here as Grin was already added, so its not a new listing but to avoid wasting time about that ambiguity I propose here to re-activation of Grin and the get required work done as defined here: bisq-network/growth#205 (comment)

If you support that proposal please upvote the DAO proposal, otherwise downvote it.
