Multi-chain payment for IPFS/Filecoin

Inspiration

Filecoin is a leading solution in decentralized storage market. It is used by lots of famous blockchain projects.e.g. Near,Polygon.it is also used by projects in NFT, deep learning.​

 HoweverFilecoin blockchain currently only support Fil as the payment token while lots of storage are not on filecoin blockchain, they need a solution pay IFPS/Filecoin by other tokens

What it does

The solution enabled the users pay IPFS/Filecoin storage by tokens on different blockchain.

How we built it

Challenges we ran into

• Build a good user experience​
• Integrate the DAO signature to unlock the contract fund​
• Using eternal adapter for update the storage proof​
• Build the testing environment: IPFS, Filecoin storage server, Lambda ## Accomplishments that we're proud of
• Success integrate the DAO for stroage proof on polygon network​
• User can pay their storage on polygon using USDC ## What we learned Build Oracle with chainlink, never give up ## What's next for Multi-chain payment for IPFS/Filecoin
• Support more blockchain​
• More token support​
• Service more than storage​
• Become a chinalink node and data provider

Built With

• go
