Hi! We are NFTHashi, a cross-chain bridge that supports transferring the NFTs between the different chains. The balance of Extensibility, Generalizability, and Trust Minimization is superior to the other NFT bridge
In this article, we’ll introduce you to our motivation, mission, and background of us. We hope you will learn more about us!
Connext provides trust-minimized cross-chain messaging. Connext is built on Nomad - an optimistic communication protocol that requires only 1 good actor in the space to remain secure.
We challenged the cross-chain NFT implementation using Connext at the ETHAmsterdam hackathon, and have been able to continue development and release the product since then. Previously, we had developed a multi-chain EVM NFT minting platform "Chocomint".
There are synergies between Chocomint and NFTHashi as well, and when the two combine well, it enables the users to create NFTs more flexibly unbounded by chains.
Cross-chain NFTs can find new use cases in NFTs that did not exist before
NFTHashi is a simple, versatile, and trust minimized NFT bridge.
Connext is built on an optimistic communication protocol Nomad, it requires only 1 good actor in the space to remain secure. This is the most trust minimized solution currently available beyond native bridges (Ethereum-L2s, IBC) that are not available across separate domains.
A message is passed by a relayer between 2 chains but, before it becomes valid, there is a 30 minutes latency period. During this time any watcher can prove that the message is invalid and slash it. It’s a fraud-proof system of optimistic rollups.

How to use our bridge is a piece of cake!
Connect your wallet.
Select the chains and go “Select NFT”
The list of NFTs you own will be shown, select the NFT you want to bridge. Make sure you select the correct NFT to bridge, if yes go “Bridge NFT”
Your wallet will be activated two times. Execute two transactions “Approve the NFT” and “Send transaction”. If everything goes well, the transaction hash will be displayed.
That’s all you need to bridge! You can find out how to check the bridge status in our documentation.

We provide the contract integrated bridge function as SDK for the users who want to create a more advanced NFT utilizing cross-chain. For example, a chain with minted NFTs, a chain with current NFTs, the itinerancy of NFT bridges, and other NFTs whose metadata changes according to these attributes, and so on, will allow for new expressions that have not been possible before!
You can create those NFTs easily by installing SDK and inheriting the contract follow the instructions in the document below.
Here's how to install and use the SDK
If you are a user who has developed contracts using the SDK, it is super easy to use.
You can integrate the NFT bridge function easily by installing SDK and inheriting the contract like OpenZeppelin.
There is an NFTHashi discord server. Let's all discuss NFTHashi feedback, the future of cross-chain, and more! Join our community !!!
