System Architecture

MALGIST is designed as a modular, non-custodial DeFi execution system built on the Mantle Network. The architecture separates strategy logic, execution, and user funds to maximize flexibility and security.

---

High-Level Overview

At a high level, MALGIST consists of four main layers:

User Interface
      ↓
Execution Orchestrator
      ↓
Universal Vault
      ↓
Protocol Adapters → External DeFi Protocols

Each layer has a single responsibility and can evolve independently.

Core Components

1. User Interface (Frontend)

• Strategy browsing & selection

• Risk disclosure and confirmation

• Deposit, withdraw, and monitoring actions

The UI does not custody funds and only triggers on-chain transactions.

---

2. Universal Vault (On-Chain)

• Single vault used by all strategies

• Holds user funds non-custodially

• Executes strategy instructions at runtime

The vault reads strategy configuration and routes funds accordingly.

---

3. Strategy Configuration

• Defines:

  • Allocation percentages

  • Target protocols

  • Risk level metadata

• Stored in a structured, verifiable format

• Read-only during execution

Strategies do not directly move funds.

---

4. Protocol Adapters

• Standardized adapter interface

• One adapter per external protocol (e.g. lending, DEX)

• Translates generic vault instructions into protocol-specific calls

This design allows:

• Easy protocol addition

• Isolated risk per integration

---

On-Chain vs Off-Chain Responsibilities

On-Chain

• Fund custody and execution

• Strategy enforcement

• Allocation logic

• Fee calculation and distribution

• Full state transparency

Off-Chain

• UI rendering

• Analytics and visualization

• Indexing and caching (read-only)

• Optional AI or recommendation engines (future)

Off-chain systems cannot move user funds.

---

Design Principles

• Non-custodial: Users always control their assets

• Composable: Strategies and adapters are modular

• Minimal trust: Execution is deterministic and on-chain

• Upgradeable by design: New adapters and strategies can be added without redeploying the core vault
