Discover opportunities to build with 4P and learn how $FOUR plays a vital part in the future of Web3 on-chain communication.
Welcome! This documentation will help you understand the development behind the 4P (i.e. 4thPillar) project. Here you will find concepts, how-to guides, quickstarts, tutorials, code examples, release notes, and more.

What is 4P?

4P = Community-build dMail & dChat project powered by the Four Tokens.
Abstract: In the ever-evolving landscape of communication, pivotal technologies have shaped how humans connect. Electrical Telegraph and Airmail once symbolized the reach of reliable global correspondence, while the invention of internet messaging transformed the way we interact at scale. Today, blockchain technology propels us into a new era of secure, non-custodial, permissionless, and decentralized digital communication. Furthermore, it offers unparalleled data ownership, safeguarded by the distributed nature of blockchain, ensuring uninterrupted access and preserving the integrity of your conversations while preventing data mining. This new technology can also be referred to as the fourth pillar of human communication, hence The 4thPillar project or short 4P.


Creation of robust Web3 communication in the form of decentralized email and messaging powered by community collaboration.

What are we building

We are building a P2P dMail & dChat platform that is non-custodial, censorship-resistant, de-platforming-resistant, data mining-resistant, and immutable with permanent permissionless access.
  • 1 email = 1 L1/L2-TX
  • 1 message = 1 L1/L2-TX

Project Design

The project's design centers around community collaboration to which any community member can contribute. Decentralized email and messaging MVPs (i.e. minimum viable product) will be deployed, and available for community upgrades and development. Open-source GitHub repositories stand ready for anyone to fork and propose enhanced functionalities. A set of smart contracts is set to enable Four Token future RTA (i.e. right-to-access) models.
  • $FOUR: A technical component in solving RTA (i.e. right-to-access), MTO (i.e. multiple-transfer option), Grants, and Governance models in the ecosystem of Web3 communication.
  • 4thTech: The project that developed the back-end genesis OCC (i.e. on-chain communication) Protocol v.1, along with the OCC SDK and dMail & dChat White-label frameworks.
  • OCC Protocol v1: A suite of EVM smart contracts [Mails, Chat, Users, AppFeeManager] that together create Web3's first on-chain communication framework, that facilitates data ownership retention within peer-to-peer emailing, messaging, data file transfers, or any other form of communication.
  • Encryptor Extension: Google Chrome Extension that enables encryption and decryption of the on-chain communication or shared data files that are created within the dMail & dChat communication.
