Many onchain apps rely on Ethereum, where simple actions can come with high gas fees. Polyupload uses Polygon instead, keeping the cost of minting a wallet-linked receipt lower and making permanent publishing more accessible.
Files disappear when they live on rented servers or fragile links. That is not how Polyupload works—we store uploaded files and their metadata on Arweave, which means the record is designed to remain permanent. If you publish something through Polyupload, the file and the metadata pointing to it are meant to stick around for the long term.
Upload a file permanently in under a minute. No account needed.
