CMTY Protocol implements an ERC-4626 vault system that integrates NFTs with real-world asset tokenization through Cyclos platform connectivity. The architecture includes bridge contracts for cross-chain asset movement, minter contracts for token creation, and NFT contracts that represent ownership of underlying assets. The treasury contract manages protocol funds and revenue distribution.

The NFT-backed deposit system allows users to deposit assets and receive NFT representations that can be traded or used as collateral. Cyclos integration enables connection between blockchain tokens and traditional financial systems for RWA management. The bridge contracts facilitate asset movement between different blockchain networks while maintaining security and auditability.

The vault system follows ERC-4626 standards for tokenized vault implementations, providing standardized interfaces for deposits, withdrawals, and yield calculations. Users can deposit assets into vaults, receive vault tokens representing their share, and earn yields from underlying asset performance. The treasury contract handles fee collection, reward distribution, and protocol governance fund management.
