I would also go with the first one [defiGa.me] due to having more potential [sounds fun] but the main issue isn't the 3 main ideas, instead is how you're going to show everyone the charity part in a transparent manner...
- Over the years, I've seen more than a few projects of this nature failed in doing that. How are you planning to do that part?
Transparency. All donations are converted to ETH and forwarded to our "incoming ERC20 Address" (IEA) that is publicly displayed.
100% of IEA is put to protocols (ie Balancer, Uniswap, etc) to earn. For that reason, the ERC20 interest payments (UNI, BAL, MTA, etc) go back to the IEA and will be consolidated for distribution per our governance.
From there, it is a matter of handling... Say the community governors decide that 50% goes to reinvestment, 30% as payouts to donors, and 20% to charity...
I will send 20% to theWaterProject crypto address and get a reciept, and publish it.
I am working with 3 enablers to automate the whole thing on chain, but not there yet.
