Installation
To add a badge to a page include the following script and html tag in your page.
TIP: you can include more than one html tag to embed multiple tokens.
<script src="https://funyproof.com/badge.js" />
<fungy-proof-badge contract="0x2352525..." token-id="12" network-id="4" />Display
The badge displays the token and it's grade by default.
Grade
Clicking on the tokens grade displays the results of the grade and each category. An option to bounce to Offsetra to purchase carbon offsets for the NFT is available under the Eco Impact results.
Verification
To certify ownership of a token. Connect a wallet (Metamask only for now) and sign a message. The wallet/address must be the owner of the NFT and the certification will only be valid for the current domain.
Once a token is verified, future views of the badge will display the tokens verified owner.
