I think this is a bad idea. Once a grant has been negotiated, executing the payment can take time. If ETH suddenly drops 20% during that period, it helps no one. The way to support the Ethereum ecosystem would be to use an ETH-based stablecoin, like RAI used to be.
Starting June 10, ETH will become the default payment method for all newly approved grants. 🦄
This brings our grant-making closer to the Ethereum ecosystem we support.
This change applies to new applications submitted on or after June 10.
