Buterin's donations also included about $4M in ETH to MIRI and two much larger donations to what might be considered EA-adjacent organizations/funds: $330M to the Methuselah Foundation, an anti-aging nonprofit, and $1B to the India Crypto-Covid Relief Fund. Those last two donations were mostly in the form of more novel cryptocurrencies whose value immediately dropped precipitously once news of the transaction spread, though, so it's not clear to me what the final value to the charities will end up being (although it will still be massive).

For perspective, $1 billion is almost double what the Lilly Endowment (the US's second-largest private grantmaking foundation) gives away each year.
