What is aegis-ledger?

Aegis Ledger is a payroll tool for decentralised organisations, known as DAOs, and other on-chain companies that need to pay contributors in USDC without revealing how much each person earns or who is being paid. The problem it targets is a specific downside of public blockchains like Solana: every payment is permanently visible, meaning a competitor or curious observer can watch a DAO's treasury and reverse-engineer headcount, burn rate, and key personnel just by analysing payment patterns over time. The tool solves this using a privacy technique called a shielded pool. Rather than sending USDC directly from the treasury wallet to a recipient's address, which would be publicly linked, each payment is deposited into a shielded pool maintained by something called the Cloak Protocol, where only a cryptographic commitment hash is visible on-chain. The recipient later withdraws the funds to a separate stealth address, breaking the link between who paid and who was paid. To stop unique payment amounts from acting as fingerprints, Aegis automatically splits each salary into standard-denomination chunks before shielding it, blending each transaction into the crowd of other deposits so individual payments cannot be singled out. All the cryptographic work, including generating zero-knowledge proofs and signing transactions, happens entirely inside the user's own browser rather than on a server. The server's role is limited to coordinating data, it never touches private keys. For compliance purposes, administrators can issue time-limited audit keys to regulators, granting access only to a specific date range of payment records rather than the whole history. The tech stack is TypeScript paired with Next.js, backed by a PostgreSQL database and Redis for caching. The full README is longer than what was shown.
