Executive Summary

Rivera Money is a decentralized protocol that enhances liquidity management by transforming concentrated positions into yield tokens compatible with the DeFi ecosystem. The protocol achieves this through its ALM (Active Liquidity Management) Vault, concentrating assets within an active range to optimize yield generation.

Rivera intends to go multi-chain and aims to enhance the onboarding experience for investors and fund managers via UX improvements. And provide a consistent interface for Defi Developers to build upon Rivera Vaults as the base layer. We focus on the scalability of the project with that in mind.

In this report, we focus on Vault contracts and Gelato relay. Strategy contract contains business logic so to avoid conflict with the value proposition of Rivera, any business logic aspect is not treated under this audit.
