Not really convinced.
You have only integrated Uniswapv3 on Arbitrum currently, so your proven collaboration with the ecosystem is as little as it can be. You say you will integrate with more, but likely this is only a comment to help foster greater alignment with your grant request.
Numbers to justify the grant have been shared, but to be honest there seems little reason for the DAO to provide a grant here. This could be put towards an existing, well established bridge that users know and trust.
