EthMail

EthMail is a decentralized communication and invoicing platform that combines OAuth 2.0-based Gmail authentication, Flow blockchain-based identity and security, and Celo blockchain-based payment settlement to enable trustless, verifiable crypto invoicing through familiar email interfaces. By integrating email login, blockchain identity binding, and wallet-based transaction workflows, EthMail enables seamless Web3-native invoicing with reduced risk, faster payment confirmation, and a simplified user experience.

EthMail bridges the gap between Web2 communication and Web3 transaction logic by integrating: • OAuth 2.0 Gmail Login – Allows users to sign in using their Gmail account, enabling quick onboarding with trusted identity providers. • Flow Blockchain Identity Layer – Anchors email accounts to verifiable, tamper-proof blockchain identities and enables future use of NFT-based mailbox ownership. • Celo Blockchain Payments – Facilitates low-cost, mobile-friendly crypto transactions that can be tied directly to emails and invoices. By combining these technologies, EthMail enables: • Secure crypto invoicing directly from email • Trustless verification of sender/receiver identity • Linked message-to-transaction workflows • Real-time payment tracking and confirmations
