Overview
NFTHashi is a Trust-minimized crosschain NFT bridge built with Connext.
Motivation
NFTHashi team wants to provide a general & trust-minimized cross-chain bridge for NFT. NFTHashi brings
How it works
NFTHashi uses Connext as an internal cross-chain messaging protocol.
The workflow of the bridge is the following.
A User deposits NFT in the NFTHashi at the source chain
The NFTHashi makes a cross-chain call through Connext
The NFTHashi receives a cross-chain message in the destination chain
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.
Team
