[Phase-2] HIP-83 Invest in Yubiai

Simple Summary

Yubiai is a marketplace developed by ProofOfHumanity community members, where you can buy & sell services, digital products and physical ones using crypto deploying on mainnet eth, gnosis and bnb, this will allow:

  1. Extreme low fees in commissions & gas in every transaction.
  2. People have the possibility to use their crypto to buy and sell in a secure and transparent way.
  3. People offer their services, physical and digital products globally.

To support the development of the Yubiai Dapp, we would like to ask the PoH for funding in return for Yubiai Tokens & an increase in PoH Dapps and user adoption.


Yubiai is a project born from the Proof of Humanity community that came together online to develop a web3 marketplace where you can buy everything with crypto. What was done so far?

At the core of Yubiai there are some protocols that give life to the platform:

  1. Gnosis Chain/BNB/ETH builds new market mechanisms for decentralized finance. Their three interoperable product lines allow you to securely create, trade, and hold digital assets on Ethereum at very cheap gas fees. Yubiai deploying on those chains is a must, enjoy the p2p transactions of everything there is on our platform at the cheapest gas prices.
  2. ProofOfHumanity a sybil resistance protocol on the blockchain, a mechanism for social identity on ethereum.
  3. Kleros Escrow, and the Dispute Resolver.
  4. Kleros Curate. “ Is this item following the marketplace rules?” By creating a list, defining guidelines and putting curation in the hands of the community you make a marketplace to operate according to our own systems of rules.
  5. TalentLayer 1 is the interoperability layer for work reputation. When you complete a job on Yubiai, you and the person you transacted with will give each other a review; growing your reputation over time. TalentLayer IDs allow freelancers on Yubiai to own your reputation as a soul-bound NFT. TalentLayer IDs are interoperable: your reputation can work on any integrated marketplaces. If you lose access to your wallet, your TalentLayer ID can be recovered to a new wallet via an emergency recovery process.

To support the team, we are asking for funding as a form of invest for future tokens from PoH over 10 ETH.


  1. Increase adoption of PoH. This will benefit PoH ecosystem and Yubiai users due to the low gas fees.
  2. Attract users and sellers to Yubiai.
  3. Add fee for every transaction (optional) to send to the PoH treasury.

Our goal is to provide a platform where buyers & sellers meet to transact in a secure, cheap & fast way. We will build a DAO in order to have project participants be in control over the project.

We believe that bringing together PoH and YubiaiDAO would be mutually beneficial to the community. By supporting the YubiaiDAO community in technical matters, such as Gnosis Chain deployment and Zodiac integration, the launch of YubiaiDAO could be facilitated.

To enable the YubiaiDAO launch team to keep developing pre-launch, we propose a token swap in which PoH would transfer 10 ETH to support the project. The majority of the funding will go towards the development of the Yubiai Marketplace and marketing.

More information about YubiaiDAO can be found in a dedicated write-up at Lite Paper 5.


  • PoH will invest 10 ETH.
  • Received funds will be managed within the DAO multisig at yubiai.eth.
  • The signers consist of core YubiaiDAO members. If interested, a representative from PoH can join the signatories.
  • yubiai.eth will hold the minter role for YBI tokens.
  • A portion of the revenues, including but not limited to transaction fees generated on the Yubiai Marketplace, will flow back to YubiaiDAO.
  • Deployment of the Yubiai Marketplace on Gnosis/BNB &ETH.


Yubiai tackles peer to peer transactions of services, physical & digital goods, NFTs using crypto as currency. We believe that this use case hasn’t been developed enough (most projects focusing on financial applications). Others projects attempting to create marketplaces, do not have the protocols that we are leveraging in order to provide the best and safest UX as well as all the incentives that are in place, such as the lowest fees from each transaction, leveraging the Proof Of Humanity community and being able to get the most out of their offerings for the seller and get their needs met by the buyers. The marketplace business has huge adoption of the total crypto population.


Once this HIP gets approved, the first release of 2.5 ETH requested for development and marketing will be sent to the Yubiai’s multisig, which will administer the funds: 0x17d79CF96896c4d2aa4d4a19a2c8dD08DaFd163D.

Divided in 4 stages:

_1st & 2nd release: would go for team salaries of dev and marketing, We will start with the implementation of the fee to the poh treasury.(at the end of the second stage the deploy of Yubiai on mainnet and gnosis will be live)

_3erd and 4th release: will be for the final steps of the implementation(testing and auditing) of the fee to the poh treasury for each transaction.(would be optional)

_ $YBI airdrop will be given to PoH users that buy or sell something on Yubiai.

_10 ETH worth in DAI equally to 1:1 $YBI. i.e if at the moment of the first stage of the release eth worth 1550, then 1550 $YBI will be sent back to the PoH treasury. Capping at max 10 eth of worth i.e if 10 eth worth 15500 dai then 15500$YBI will be sent to the poh treasury at then end of the final stage.

Funds Allocation Details

Team salaries



3 ETH (focusing 50% on the weeks before and during the launch). The rest to maintain a stable {but less intensive} (marketing effort for the rest of the year). This rest would be locked and would be unlocked progressively on time.

Our plan to acquire users and get traction consists in an elaborate marketing plan to raise awareness of the project. This will consist of several ways to increase visibility and grow usage of the platform, such as through paid campaigns like Search Engine Marketing and Display Ads, collaborating with influential content creators and bloggers, promoting the product on social networks, implementing referral and affiliate programs, and hosting offline events such as meetups and workshops to build community and introduce new features to attendees.

The marketing plan will feature a timeframe of 4 weeks, which will consist of conveying the message about the project and building hype around it. This will be accomplished through live demos, Q&A sessions, and Twitter Spaces over the first 2 weeks. The following weeks will focus on having a strong presence throughout all social media platforms. Once we receive funding from investors and grants, we plan on further expanding our marketing push through collaborations with influencers and KOLs.

All in all, we want to ensure that there is no possibility of failure by simplifying the setup process so that it is easy for anyone to follow and execute. Let me know if you would like to see the latest version of the marketing plan.
