Vasco

Inspiration

Currently there is no NFT bridge between Ethereum and Avalanche.

What it does

Uses the ChainSafe ChainBridge v2 with a modified relayer to bridge NFTs from Ethereum to Avalanche (work-in-progress).

How we built it

Smart contracts: ChainSafe ChainBridge v2 API: queries a hosted subgraph that indexes all NFTs for data, then queries metadata (URLs) Frontend: TypeScript React

Challenges we ran into

Adapting ChainBridge to the ERC-721 handler. Apparently ConsenSys is about to push some code!

Accomplishments that we're proud of

Even though project is not technically working end-to-end, significant progress in adapting from ERC-20 to ERC-721, frontend is solid.

What we learned

Bridges, subgraphs and wiring it all up!

What's next for Vasco

When ConsenSys pushes their PR, getting everything working end to end.
