How it works

How it works

NFTHashi uses Connext as an internal cross-chain messaging protocol.

The workflow of the bridge is the following.

1. A User deposits NFT in the NFTHashi at the source chain
2. The NFTHashi makes a cross-chain call through Connext
3. The NFTHashi receives a cross-chain message in the destination chain
4. The NFTHashi mint corresponding NFT to the user in the destination chain

Brided Information

• The contract address is calculated from the NFT original contract address and chain. It uses create2, so the address in the destination chain is calculated counterfactually.
• Token ID is the same for both the source chain and the destination chain
• Token URI is copied and bridged to the destination chain

Security Concerns

• NFTHashi leverages Connext, so we have the same security model as Connext.
• NFTHashi uses Lock & Mint model in the bridge. And NFTHashi team has an upgradability role in the contract in the early time. This is an additional trusting point on top of Connext.
