Inspiration

There is no border among different blockchains.

What it does

We have developed ORAIDEX that helps to swap assets, including tokens and NFT, on different blockchains quickly.

How we built it

1. We have created two Cosmos-based blockchains, namely Mars and Earth.
2. We configured IBC between Mars and Earth.
3. We created an NFT marketplace as a demo. We built this marketplace on Mars.
4. Users with $EARTH on Earth can buy NFT on the marketplace running on Mars through IBC.
5. The exchange rate is fixed between $EARTH and $MARS. Soon, we will develop AMM and price feeds for swapping.

Challenges we ran into

• Wasm v0.14 has no document.
• It takes time to develop the frontend.

Accomplishments that we're proud of

We can do real-time purchases using $EARTH on the marketplace running on Mars.

What we learned

How to use IBC and build an NFT marketplace.

What's next for ORAIDEX: cross-chain exchange for tokens and NFT

We want to support non-Cosmos blockchains and NFT cross-chain swaps.
