Normal Finance is a protocol for on-chain crypto index tokens and synthetic assets. It provides an AMM with oracle-based pricing, index creation (public/DAO-governed or private), minting/redemption via deposits of SOL, XLM, or USDC, and a fee model with a protocol fee and optional manager fee collected on qualified transfers. The protocol maintains an Insurance Fund for liquidity shortfalls and a unified liquidity vault that allocates XLM/SOL liquidity to pools.
