Mint Your Limited Edition rhino.fi Power User ZK Badge (Soulbound Token) – Become a ZK OG

NOTE – this post is being used as supporting material for the Sismo Governance vote (moving the Rhino.Fi ZK Badge from the Playground to Currated section of the app) and will be announced & published more widely if the Governance vote passes

Regular rhino.fi power users can now mint a limited edition Sismo Protocol Zero-Knowledge Badge to show proof-of-OG-rollup status to the world, without having to DOX your wallet. 

The rhino.fi ZK Badge is open to both new and existing rhino.fi users. Join the ranks of the select few ZK Badge holders and flex your OG ZK status – mint your badge now! 

What is Sismo?

Sismo Protocol uses zero-knowledge proofs to generate zero knowledge attestations in the form of non-transferable badge (a.k.a Soulbound Tokens) NFTs. The protocol can be used to aggregate reputation from a number of different source wallets without publically linking them to each other or a destination. Users can mint badges on completely separate destination wallets to avoid having to publically DOX their wallet. They also threw a great zk masquerade party at EthCC this year 🎭

Why is rhino.fi so Excited About Sismo?

As the first rollup to be deployed on the Ethereum mainnet in 2021 rhino.fi is passionate about all things ZK. As rhino.fi is a Validium rollup, user data is held off-chain, meaning activity on the platform is known only to the rhino.fi operator and the individual users. As activity is not published on-chain, users of fhino.fi benefit from casual privacy, but have no easy way to show the world how they are both early adopters of ZK rollups. Until now… 

The rhino.fi Power User ZK Badge is the first Sismo ZK Badge that has been approved by the Sismo DAO governance process, joining the ranks of small number prestigious projects to have zk badges, including POAP, GitCoin and ENS. 

It’s time to flex your OG status, and prove you were among the first in the space to use ZK. We hope that other projects will utilize the Rhino.Fi badge for new and exciting use cases going forward. 

Power User Badge Criteria 

Regular rhino.fi users are already eligible to mint the Power User badge. Regular usage includes swapping or trading on the rhino.fi platform over a period of several weeks. 

The exact criteria is top secret, but if you have swapped or traded on rhino.fi over a period of several weeks then you will likely be eligible. You can check the list of the initial c.5000 list of eligible users here.

How to mint your Rhino.Fi ZK Badge?

Before you can mint the rhino.fi Power user badge, you first need to setup your Sismo Vault – 

Your Sismo vault is your badge minting control center on the Sismo Protocol. Your vault connects any number of your source addresses (different addresses that may be eligible for badges based on a set of criteria) to the destination address (an address where you wish to eventually mint badges to). Don’t worry, you can change all of your source and destination wallets at any time 

Go to app.sismo.io/rhinofi-power-user and connect your wallet using the “Sign-in to Sismo” button in the top right hand corner of the screen.

Supported Wallets:

• Metamask
• Wallet Connect 

Not Supported Wallets: 

Follow the vault creation flow and sign with your wallet to create your vault.

Specify any number of source addresses that you think may be eligible for a rhino.fi badge by adding them to your Sismo vault using the top right hand corner menu.

Specify the destination address where you wish to mint your rhino.fi badge. This can be the same as one of your source addresses or a completely new address that you have just created.

Once your vault is deployed and setup with source addresses, you can now check your eligibility for a badge. Click the rhino.fi Sismo badge link here.

If you are eligible then you will be allowed to mint your badge. If you are not eligible, then keep trading & swapping on rhino.fi and check back monthly to see if you are eligible. 

Follow the steps to mint your badge, by specifying a destination address.

Your badge will be minted on the Polygon network and should be visible in your rhino.fi portfolio as well as your Sismo Protocol vault within a few minutes. 

You can also view your badges on Opensea, but you may have to unhide them

What is a source account?

A source account is the account that must meet the badge requirements. If eligible, a source account will be used to generate an eligibility proof used in the Badge minting process.

ZK Badges – Your sources are private

When minting a ZK Badge, you will NOT reveal your source account. You will generate a ZK Proof of ownership of an eligible source account without revealing its address!

Who can access my vault?

Only you can access your vault. Your Vault is encrypted thanks to your owners accounts. You can go to your settings to manage your owners.

Importing a source, what does it mean?

Importing a source into Sismo’s vault just means signing two messages necessary to generate the ZK Proofs required for minting ZK Badges.

The signatures are stored in your encrypted vault so you do not have to sign messages each time you want to mint a new Badge.

What if I am not eligible?

Never fear, you can earn the right to mint the rhino.fi Power User badge by swapping & trading on rhino.fi over the coming weeks and months. The list of eligible addresses will be updated once per month, so keep swapping, trading and checking back to see if you are eligible!

I have more questions – where can I go?

Please ask any questions on the rhino.fi Discord 

If you like what you see and would like more badges, then let us know on Discord. We love to hear your feedback!

The only thing left to say is, CONGRATULATIONS, and welcome to the future of Ethereum!
