I think strategically it is better to start by asking to Kusama Treasury as suggested by Julien Eluard, a parity engineer based in Toulouse. The w3 grant must be asked when we are ready to accelerate a lot. We might want to do it on september 2023 and combine it with ADEME funding.
[edit] @davidbp845 can you dig on Funding Duniter with Kusama with me?
