Cross-Chain Data Bridge Demo (Filecoin & Avalanche)

This repo demonstrates how to onboard data from Avalanche to Filecoin via a cross-chain data bridge protocol, which processes storage proposals on Filecoin. It could potentially process the data storage coming from multichain, such as Linea, Base, Arbitrum, etc.

The demo consists of the following components:

• Demo UI: upload file via onramp contract
• Onramp Contracts: accepting storage requests & posdi proof verification.
  • The onramp contracts were deployed on Filecoin Calibration & Avalanche Fuji testnet. You can find the contract info in contractDetails.tsx.
  • You can also deploy your version of onramp contracts.
• xClientClient: listen to the storage requests from smart contract, aggregate small size of data and send storage deal proposal to SP on Filecoin.
