Eppie develops a decentralized email client and peer-to-peer messaging system with end-to-end encryption, distributed storage, cryptographic addresses, seed-phrase recovery, and compatibility with traditional email accounts. Its architecture uses cryptographic keys, DHT/SBBS transport, and IPFS storage, and it is expanding into integrations with Bitcoin, Ethereum, AI agents, DAOs, NFTs, and other on-chain identities. The project is open source and offers beta or early access through its website.
