If you attended ETH Denver and wanted to claim 50 GoerliETH but couldn't do it so far, you should be able to do it now. We updated the Merkle Proof to include all participants' addresses. Thanks to Olly from SimpleHash for helping me with their API 👊 https://goerlinator.xyz/
cc: @jessepollak IIRC some people from the Base team couldn't claim, they should be able to do it now :)
