FileMarket

FileMarket is a Web3 file-sharing and marketplace platform that lets holders of EVM-compatible wallets store digital content directly against their wallet and monetize it by selling access through a public showcase. The product is built around an Encrypted FileToken (EFT) standard that combines tokenized paywalls with on-chain programmable access, with the stated aim of turning a crypto wallet into a "My Documents" folder that merges cloud-storage convenience with blockchain-based ownership and decentralized, long-term storage.

In the platform's flow, a file is symmetrically encrypted and uploaded to Filecoin via the Lighthouse storage service at the moment an NFT is minted. A buyer freezes payment tokens in a smart contract and transmits a public key to the seller; the seller then sends the encrypted file-decryption key back using asymmetric encryption, after which the buyer retrieves and decrypts the file from decentralized storage. A backend service monitors transactions so that a buyer who receives a file that does not match the sample or cannot be decrypted can file a fraud report; if the buyer is satisfied, the reserved funds are released to the seller. Ownership transfers between wallets follow a comparable key-exchange cycle, and access to the encrypted file passes to the new token owner while the previous owner loses it.

Business model

The platform intermediates peer-to-peer sales of access to encrypted files: creators mint tokens representing encrypted content, set access terms, and receive payment in crypto through smart contracts that escrow buyer funds until the transfer of decryption keys is completed.
