Abstract — SolMail V2

What is SolMail?

SolMail is a wallet-native, censorship-resistant, and end-to-end encrypted communication protocol built on the Solana blockchain. It transforms email — the most universal identity and messaging system in the world — into a Web3-native primitive, where every user’s wallet is their inbox, their identity is an asset, and their email becomes a passport across decentralized applications.

With SolMail:

  • Your wallet is now an inbox → Your Solmail wallet can receive messages, invoices, or crypto assets.

  • Identities are assets → Usernames like name@sol.mail and domains like dao.mail are NFTs, ownable, tradable, and programmable.

  • Messages are programmable → Beyond text, messages can carry payments, NFTs, contracts, signatures, or DAO proposals.

  • Privacy is the default → End-to-end encryption, metadata minimization, and on-chain proofs replace surveillance-driven email models.

  • Universal Web3 Login → SolMail IDs act as a single sign-on (SSO) credential for the Solana ecosystem, enabling users to access dApps and platforms securely with one wallet and one identity.

Why SolMail?

Legacy email is centralized, surveilled, and fragile:

  • Mailboxes are rented from providers (Gmail, Outlook), not owned by users.

  • Sender authentication is patchy, enabling phishing, spam, and impersonation.

  • Payments, contracts, and workflows are fragmented across external systems.

SolMail solves these gaps by design:

  • Interoperability → Handles, domains, wallets, and Solana Name Service all resolve to a single, verifiable communication standard.

  • Censorship Resistance → The protocol has no gatekeepers; rules are enforced by math and governance, not corporations.

  • Communication + Settlement → Messaging, payments, and signatures converge in the inbox.

  • Identity Sovereignty → Every identity is cryptographically secured and tradable.

  • Universal Web3 Access → Users can log in to multiple Solana dApps with their SolMail ID, consolidating identity and wallet management into a single secure layer

Mission

SolMail’s mission is to onboard the next million users to sovereign communication and identity on Solana by:

  • Making email-style onboarding simple and familiar for new users.

  • Embedding financial and organizational primitives (payments, contracts, governance) directly into messaging.

  • Acting as a universal login and identity service for Web3 users across Solana platforms.

  • Ensuring trustless, censorship-resistant coordination for individuals, DAOs, enterprises, creators, and NGOs.

Principles

  • Privacy by Default — End-to-end encryption, client-side storage, and cryptographic sender verification ensure no central authority can surveil or censor.

  • Ownership by Design — Identities, messages, and namespaces are assets you own, not licenses from intermediaries.

  • No Gatekeepers — The protocol is open, permissionless, and censorship-resistant. Anyone can send to a wallet, even without an account.

  • Security Over Hype — Technical integrity is prioritized over marketing narratives; claims are grounded in code and on-chain proofs.
