How it works
Polyupload turns Polygon into a portable index for your Arweave uploads. Each wallet can deploy a personal ERC-721 collection and mint a non-transferable token for every upload. The token acts like a permanent on-chain receipt that points to the file's metadata on Arweave (for example an arweave.net link or tx id).
Tokens are soulbound by design (locked per ERC-5192), so uploads stay tied to the wallet that created them while still remaining burnable if you want to remove a reference. In practice, it's a clean file-storage abstraction: your wallet is the account, your contract is the bucket, Polygon is the index, and Arweave is the durable data layer.
