Recent years have brought a number of innovations in the Web3 and cryptocurrency sector. The number of new blockchains and protocols built on them is constantly and dynamically growing. While this is a positive phenomenon, it also presents a number of problems.

Ecosystems fragmentation As each new ecosystem builds up and grows along a given chain, so does the total value of assets, liquidity, and the user base which do not add value to other ecosystems. One of the main advantages of decentralized applications is their openness. This allows other protocols to use the achievements of other ecosystem participants, or to extend their properties. This makes it much easier to create a common, decentralized system that constantly offers new possibilities. Unfortunately, the above is most often true only in relation to protocols built inside a specific blockchain (ecosystem). For example, the total value locked on an Avalanche is an added value only for that network and cannot be used by protocols created on other chains. Likewise, an NFT representing a decentralized user profile or an in-game item is not reusable on multiple blockchains simultaneously. The above is an obvious disadvantage in terms of the aforementioned openness of the application as well as a huge squandered value that could be used by other users.

What it does

  • Creating Omnichain NFT collections and minting between chains to unify fragmented ecosystems and abstract away Web3 core infrastructure for the end user improving User Experience.
  • NFT creators can now reach a much wider audience. Launching a collection with a no-code interface allows users from different chains, e.g. Polygon, to mint from the creator's collection.
  • Collectors can mint from collections created on chains different than the user is connected to - all without switching networks and bridging funds.
  • Our Omnichain Router makes cross-chain protocols and applications development really easy. It connects multiple cross-chain messaging protocols like LayerZero and Axelar to aggregate all their supported blockchains into one solution (redirection logic).
  • NFT Gateway allows bridging ANY ERC-721 NFT between all 9 currently supported "cross-chain" networks. Moreover, it's superior to other NFT bridges because it allows the token owner to recover the original NFT on the source chain. It's also composable. When a bridged copy changes owner on the destination chain, the original will also be recoverable for the new owner. It allows advanced cross-chain use cases like in-game bridging.
  • Storing all created NFTs on IPFS automatically.

How we built it

I initially built the Omnichain Router out of my own need as the internal solution to make it reusable and abstract the cross-chain layer from the application logic layer. Learn more from our Documentation at

Challenges we ran into

From the very beginning, the project was developed by only 1 core developer (founder) and funded from my own resources.

Accomplishments that we're proud of

  • Mainnet launched
  • First collections deployed on multiple chains and minted using cross-chain messaging.
  • First NFT Gateway usage. Users already bridged some of their NFTs.
  • Relationships with major projects and teams.

What we learned

I've learned that everything is possible, that team is hard to build but in the end, it's people who can build the project value, and that task delegation is crucial.

What's next for Omnisea

Team expansion, looking for funding to make development and growth more dynamic, improving Launchpad in many ways, adding new chains - both cross-chain (with current support of LayerZero or/and Axelar) as well as "isolated" - where creating collections and minting is available on/from that particular chain without the support of cross-chain features (these chains will be turned to fully cross-chain compatible with the LayerZero/Axelar integration).
