Project Overview


$12,500 (twelve thousand five hundred USDC) to fund the efforts to build a non-transferable token (NTT) primitive as a public good that helps solve many coordination problems faced by Radicle as a whole, the Radicle Distribution of Influence workstream, and DAOs more generally. The effort is led by the Otterspace team which aims to build this as public good infrastructure for the Ethereum community. We ask for $5,000 (five thousand USDC) now, for the scope covered in Milestone-1, with the intention of setting ourselves up for success in a long-term partnership and to show our commitment.

The implementation is broadly inspired by what is popularly known as “Soulbound Tokens”, as coined by Vitalik Buterin in a blog post and recent paper co-authored with Glen Weyl and Puja Ohlhaver. Otterspace is building a Badges Protocol with NTTs as the underlying primitive. We propose to provide Radicle with a model using Soulbound contributor badges, aligned with the RadicleDAO’s workstream objective i.e., designing and implementing a strategy for distributing non-financialized governance power within the Radicle ecosystem. Additional context on our thesis is hosted here.

We recently published the EIP-4973 which is actively collecting peer feedback in its “draft” state. We already released the first version of this with the “Otter Soul Minter” app. This token model, along with Otterspace’s Badges Protocol, would improve the membership management challenges faced by DAOs such as Radicle, in particular by enabling an additional governance mechanism that allows for a non-financialized form of participation that can be distributed and earned.

Note: we intend to raise public goods funding only to fund the public good infrastructure i.e., all the efforts towards building the EIP(s) and the work focused on Radicle integration. All the work pertaining to Otterspace’s core platform or application building is out of scope for this funding request. Part of this request is also to fund some of the efforts retroactively. We are also considering raising additional funds from the wider ecosystem in due time.

Project Details

Problem statement

The current coordination primitives for DAOs are insufficient for them to be able to realize their potential. In most cases, DAOs coordinate internally with the help of a fungible or non-fungible token. Tokens bestow ownership, governance power, contribution power, and access to DAO spaces, events, and other resources. Many challenges to this single-token model have emerged:

  • The current token model does not reflect the diverse & multifaceted nature of membership
  • Rewards and incentives are entirely financial, reputation is not captured
  • DAOs are not as autonomous and permissionless as they could be
  • Coin voting is vulnerable to vote-buying and other challenges
  • Tendency towards “aristocracy bias” within token distributions, whereby token holdings are concentrated among a few early individuals that may not be actively contributing to the community

In the case of Radicle, challenges have emerged with low voter engagement, the concentration of ownership, and centralized influence. By financializing governance in the DAO, early investors and supporters of the DAO hold disproportionate governance power. In March, the workstream around the distribution of influence was introduced to address this problem head-on. In the next section, we will describe how Otterspace will address this challenge.


Our vision is to give DAOs the tools to better represent the diverse nature of membership and improve member engagement, coordination, and distribution of power and permission. By doing so, we also aim to progressively improve their autonomy and enable them to be more permissionless, while surfacing clear paths and incentives for individual members to deepen their participation.

We believe that a new primitive is needed for better incentives, membership, and coordination within DAOs - through NTTs i.e., Account Bound Tokens or Soul Bound Tokens. A full blog post about how the Otter Badges address these challenges can be found here: part 1, part 2.

Some of the work in progress can be found here (in addition to code repos shared above), which we hope underlines our approach to building in public and with the broader community:

Radicle Solution
In the case of Radicle, we will support the Distribution of Influence workstream by providing the team with a tool that allows Radicle to mint and distribute NTT badges to community members. After a badge is designed, vouchers are issued to eligible members, who are able to claim and mint their badge. In later iterations (not covered by this proposal), badges will be able to be claimed permissionlessly when specific criteria apply. These criteria are defined by the badge designer and may include on and off-chain activities. The revocation and reassignment of badges are also planned for a later release.

Once badges are minted and held by members, they can be used to distribute governance power or bestow social capital within the DAO. They may also be used to unlock access to DAO tools via token-gating. Otterspace is working on integrations with all major DAO tools to support this new primitive, including (but not limited to) Wonderverse, Snapshot, Discourse, DeWork, Coordinape, Utopia Labs and Clarity.

In addition to the creation and distribution of these contributor badges, the scope of this proposal also includes an integration with the Drips Protocol, which will require some collaboration with the Radicle team. The purpose of the integration is to allow drips to be directed at all holders of a badge, such that badge holders receive a regular payment for as long as the badge is valid. For example, any holder of a core contributor badge could receive a weekly stream of tokens so long as the badge is valid.

Measuring Success

We will primarily measure success with adoption by members - “number of badges minted”.

We intend to build this closely with Radicle first and a few other DAOs as pilot users, with whom we will collect qualitative and quantitative feedback on impact & usability.

Budget & Funding

A lot of this work is an effort towards building this as public good infrastructure and our motivation is to support this via public good funding.

Additionally, we want to work with Radicle DAO closely to build around their needs before generalizing the protocol for more use cases. This also involves integration with Drips.

Note: We haven’t applied for previous grants or additional sources yet.

Thanks a bunch for dropping this application in.

I’ve sat in 2 meetings with you all, so don’t have much else to say here.

I’ll start gathering votes for this (it’s a “yes” from me).


Hey Otters! Thanks so much for the detailed application! :seedling:

I have a conflict of interest in this so I’ll have to sit out on voting (I advise the Otter team), but @bordumb I wanted to ask you how you see these milestones playing out with our Distribution of Influence work that we’re kicking off next week? If Milestone 2 is to distribute otter badges to Radicle contributors via the Otterspace app, then we probably need to know how we want to distribute influence to contributors by then. Do you think we can align timelines by then?

Also, seems like there might need to be some slight re-evaluation of the milestone timelines @rsquare!

I’m amending the timeline on behalf of @rsquare since some time has passed since we submitted this grant application. We have been working on the first part (MS1), so the funding request for that is retroactive.

Milestone 1 - April - June 2022
Working implementation of soul-bound tokens on a test network

  • Draft EIP 4973: Soul Bound Tokens & collect peer reviews
  • User interviews with DAOs on membership models using NTTs
  • Compatibility coverage & testing for Wallets, APIs, NFT Marketplaces, etc
  • Backward compatibility testing with ERC721
  • Build Otterspace Badges Protocol on top of EIP 4973
  • Write a light paper on Badges protocol
  • Launch “Otter Soul Minter” app on Testnet

Milestone 2 - July - August 2022

  • Launch a proof-of-concept app for Otter badges with Radicle
  • Launch the app for self-service options for DAO members i.e., design, distribute & claim badges
  • Host a publicly accessible subgraph documentation for badges
  • Build a publicly accessible dashboard on Dune
  • Plan the integration with Drips via collaboration with the Radicle team to scope integration requirements and approach

August and beyond
MS-X: Future plans

  • Build integration with Drips protocol
  • Extend protocol for L2 compatibility, starting with Optimism first & Polygon later
  • User testing with more DAOs
  • SDK Development & integrations with DAO tools (snapshot, dework, clarity, etc)
  • Progressively decentralize maintenance of the Otter Protocol to the community
  • Research additional models for designing NTTs

Hey @abbey : yes, that sounds good. Let’s do a public meeting on Discord to discuss

@emily Thanks for the update. Regarding the vote/pay-out process for the 2 milestones listed above:

  • Milestone 1: if passed, 20% of funds will be dispersed immediately (1,000 USDC). Once completed/approved, the remaining 80% will be dispersed upon approval (4,000 USDC)
  • Milestone 2: will only start once Milestone 1 is fully completed. The voting funding process will follow a similar schedule as Milestone 1.

Hi @emily

Thanks a bunch for dropping the notes on Milestone 1 delivery.

I’ve skimmed through all the docs you’ve laid out.
And I’ve gone through the entire process of allocating badges to members of the Grants Committee.

So from perspective, everyone looks good to me.
It was very seamless on test net :slight_smile:

I’ve started the payment for this on our multi-sig.
You can find it on Nonce 34 below:
