Community-build dMail & dChat Super App powered by Four Token

We build a W2W E2EE dMail & dChat self-custodial application with permanent permissionless access resistant to censorship, de-platforming and data mining.

Discover opportunities to build with 4P and learn how Four Token plays a vital part in the future of Web3 OCC (on-chain communication).

"on-chain" communication fundamentals

4P leverages blockchain to provide secure, immutable, and self-sovereign communication without risking data ownership.

4P uses PollinationX decentralized storage NFTs to let users maintain data ownership and control over their communication, accessible only with their private key.

Unrestricted access ensures users can’t be de-platformed, with communication on 4P dMail & dChat unlocked solely by the user’s private key.

Communication is executed on public blockchains accessible and decryptable only by user’s private keys. In the case of the 4P downtime, anyone can spin up and run their open-source dMail or dChat client and access their communication data.

Encryptor Extension adds the communication E2E encryption layer within dMail & dChat currently unsupported in major wallets granting users unprecedented self-custody over their communication with personal encryption keys for full control.

Due to the 4P’s decentralized and self-custodial design, the users are in complete control over their data. No data ownership is lost or data mined in the process.

Multi-chain asset, a technical component & incentive vehicle
