Launches: will make Harmony cross-chain operable

Name of Project / DAO / Company


Application type


Proposal overview

Rubic is a multichain DeFi ecosystem which features cross-chain, P2P, instant swaps and limit orders across multiple blockchains, aiming to deliver a complete ONE-STOP decentralized platform.

Beside Binance, Polygon and others we are also already partnered with Harmony and integrated it on our platform last month - followed by some mutual marketing campaigns and a trading competition.

Rubic recently launched its cross-chain routing protocol, enabling all of our users to swap between 7,500 tokens on ERC, POLY or BSC in a one-click step and no KYC required. We are a first-mover here and its the first REAL cross-chain routing.

We are now aiming to integrate Harmony to our cross-chain routing protocol as well, which will draw a lot of attention to the Harmony chain and allows easy access for countless users to it. The cross-chain routing is nothing less but a game changer in crypto and we want to have Harmony as a part of it.

Such an integration requires appropriate development, resources and time. Accordingly, we are dependent on the financial support of Harmony in order to be able to achieve our goal.

We would also like to have another joint marketing campaign as soon as Harmony is cross-chain operable. Our marketing teams are already in contact.

@Sven_Rubic please review the guidelines for Launches

  • 500 Launches ($20M). Applications of each launch must have prototyped a feature-full product. Harmony helps incubate these founding teams with product development, fundraising, and talent recruit. We recommend a $50K equity-free contribution each: $10K after launching a feature-complete product on our testnet, $10K after mainnet launch, $10K after forming a DAO with its community, and $20K for after 10K users.

The metrics for success in unclear, we look for utility (e.g. 10K users). Please describe the timeline for milestones as well


@Jacksteroo thank you for your feedback.
To be clear: This is not about a launch (category has been choosen wrong) but an expansion of our product regarding the implementation of Harmony into our cross-chain routing and strengthening of our existing partnership with Harmony.

Regarding the metrics for success: It is kinda difficult to predict. Our current volume is around $5mln per month with 1000+ unique users and we are growing fast.
Cross chain excludes barriers between Ethereum, Polygon, BSC and Harmony. Our solution is a simple way to do swaps, hence we open the door for users that dont whant to have the hassle of finding and using complicated bridging and swapping tools.

This solution will provide a simple way to all DeFi users to Harmony.

The development time this would presumably take is 6 - 8 weeks.


So let me get this straight
Your goal is to allow seamless cross chain swapping between ETH, BSC, Polygon, and Harmony $ONE?
No pesky bridge needed, simplify the process with just one step


Pretty much, sounds good


They have alredy done that btw eth, bsc and matic.


Just come across and being doing some research and what you guys are doing over at Rubic will revolutionise this space. Big thumbs up here


Wow! This is awesome.


Rubic is integrating all the chains, bridges across different networks. Harmony is the one in the works currently and has a working bridge already.


Rubic looks like a killer! Harmony get this one please!


Yep, they’re really filling a huge gap in DeFi


Rubic is exactly what defi and a cross chain ecosystem needs. It is an incredible group of people that have made striking growth in the past year, and will complement the harmony ecosystem quite a bit. Already partners. Please choose this Harmony, you won’t regret it!


@Sven_Rubic looks like there’s a huge swell of community support. We’ll circle back to you soon.


Rubic: a project that has already revolutionized the cryptospace. :green_square: :mechanical_arm:
Harmony should hold RBC tight. :blue_square:


Harmony, please do the needful and make cryptospace green and cubic again. :blue_heart: :green_square:


Harmony and Rubic belong together. :green_square: :blue_heart:


Rubic is a really great project, it’s so undervalued right now. As soon as the masses start to realise how useful and convenient it is it will blow up

As the saying goes: If you want harmony :blue_heart:, prepare for building bridges :bridge_at_night:. That’s what Rubic is all about. :green_square:
