Non-transferable Badge
The MetoBadge protocol allows communities to create, issue and manage their SoulBound Tokens.


  • Minting: Communities and authorized signers can generate an EIP712 voucher which will trigger the mint process once claimed by the member.
  • On-Chain Data: The functions of the MetoBadge allows it to be updatable on-chain. For example, if a contributor spends more time on a project, the metadata is able to be updated by the community- saving on gas fees to mint a new MetoBadge.
  • Non-Transferable: The function of non-transferability comes from the idea of a SoulBound Token, therefore creating a more transparent ecosystem as MetoBadges are not purchasable. It is earned through collaborating, participating and building.
Some common examples of the MetoBadge use-cases for communities:
  • Proof of Membership
  • Proof of Contribution
  • Proof of Partnership
  • Governance Role and Voting
