Upload once. Store forever.

Polyupload stores your files permanently and gives every upload a verifiable on-chain record.

How it works

  1. 1

    Store the file

    Choose a file and store it permanently on Arweave.

  2. 2

    Mint a wallet receipt

    A non-transferable ERC-721 receipt is minted on Polygon and locked by ERC-5192.

  3. 3

    Find it later

    Your wallet becomes the account, your collection becomes the bucket, and every upload stays easy to find.

Polygon

Polyupload runs on Polygon

Many on-chain 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.

Arweave

Polyupload uses Arweave

Files disappear when they live on rented servers or fragile links. Polyupload stores 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.

Make it permanent.
