OFFICIAL ANNOUNCEMENT: ONFA Token (OFT) & Metti Token (MTT) Smart Contract Upgrade

Dear ONFA Community,

In alignment with our long-term vision to develop a next-generation financial ecosystem, ONFA is pleased to announce the official smart contract upgrade for the following assets on BNB Smart Chain:

• ONFA Token (OFT)
• Metti Token (MTT)

This upgrade introduces an enhanced architecture designed to support quantum-inspired financial infrastructure, enabling improved transparency, system integrity, and real-time state verification across the network.

I. UPGRADE OBJECTIVES

The new smart contracts are developed to:

• Implement a Quantum State Tracking model for on-chain asset management
• Enable real-time wallet state verification (Quantum Snapshot)
• Introduce system-wide reconstruction capability (Quantum Insurance Layer)
• Strengthen security, risk control, and operational resilience
• Prepare infrastructure for advanced features such as cross-chain interoperability and programmable finance

As part of our ongoing system optimization, ONFA has also integrated additional security layers to ensure long-term ecosystem stability.
