Onchain IPFS
Store files referenced by Ethereum L1, on L2! A 100% Ethereum-aligned alternative to Arweave. Helps Arweave itself to be linked to an IPFS CID.
About
The problem it solves Currently, Filecoin and Arweave (two non-Ethereum L1s) are the only way to store NFT metadata and other IPFS files' contents onchain. On Arweave, it is harder to obtain the file content for those used to IPFS. Onchain IPFS come to solve both issues: onchain storage (using the Ethereum-aligned L2 Base) and linking: CID<->Arweave TXID<->Torrent URI.
How it's made
Challenges we ran into Remix IDE's "Stack too deep" issues.
