OVERVIEW

NoaFi is a privacy-native finance layer built on Solana, designed to let users transact, swap, invest, and manage portfolios without exposing their wallets, strategies, or transaction history to the public blockchain.

It positions itself as a high-speed, non-custodial privacy layer where users still own their wallets, but all financial actions flow through an encrypted "shadow balance" that hides activity details from on-chain observers.

The protocol consists of several core modules:
- PROOF_ENGINE: Generates and verifies ZK proofs
- KEY_DERIVATION: Manages hierarchical key structures  
- TX_SHIELDING: Wraps transactions in privacy layers
- RELAYER_NETWORK: Decentralized transaction submission

NoaFi is designed to be composable, allowing developers to integrate privacy features into existing applications without rebuilding from scratch.
