1. Executive Summary

Maple Finance is an institutional capital marketplace that relies on pooled lending, decentralized credit underwriting (Pool Delegates), and derivative debt tokens. This security review evaluates the Upgrade Compatibility Risk Profile associated with structural protocol enhancements—specifically focusing on storage layout continuity, ERC-4626 vault standardization, asynchronous debt accounting, and cross-chain parameter synchronization across Ethereum L1 and L2 deployments (Arbitrum/Base).

The architectural design is robust; however, upgrading stateful proxy contracts managing over $2.7B in active assets introduces critical attack vectors related to storage collisions, loss-accounting race conditions during pool
