First, download the Metamask Chrome extension (https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn?hl=en) and follow their setup instructions to generate a new wallet. You do not need to own any cryptocurrency to sign this Declaration. After you have a Metamask wallet, click sign. Please note that the public address of your wallet will be displayed upon signing - we recommend you create a brand new wallet.

Metamask will now pop up in a separate modal.  You will see the document that you are signing in the box; click "Sign".

After you've signed, you can tweet to prove you own this Twitter address and verify your signature. We encourage you to verify on Twitter! We are prioritizing verified signatures in the list order to mitigate any Sybil attacks / identity theft.

That's it! Thank you so much for being part of this web of interdependence.
