Technical Architecture

Thesauros is built on a robust three-layer architecture that separates concerns between on-chain execution, off-chain computation, and automation logic.

Smart Contract Layer

Core Components:

• ERC-4626 Vaults: Industry-standard tokenized vaults (full DeFi composability)

• Strategy Contracts: Execute rebalancing logic and interact with lending protocols

• Multi-sig Security: All rebalancing operations require multiple approvals

• Emergency Controls: Pause mechanisms and withdrawal safeguards

Key Benefits:

• Full transparency: all allocations visible on-chain

• Non-custodial: users retain ownership of their assets

• Auditable: all transactions permanently recorded

Data Intelligence Layer

Optimization Engine:

• Runs Particle Swarm Optimization algorithms to find optimal allocations

• Simulates thousands of potential portfolio configurations

• Uses local blockchain forks (Hardhat) to model protocol behavior accurately

• Provides results via secure internal API

Market Analytics:

• Real-time APR aggregation from integrated protocols

• Historical performance tracking

• Liquidity depth analysis

• Risk metric calculations

Why Off-chain: Complex mathematical optimization would be prohibitively expensive on-chain. By computing off-chain and only submitting results for on-chain validation and execution, Thesauros achieves both sophistication and cost-efficiency.

Automation Engine

Multi-Approval Security Architecture:

Proposer Service          Approver Service         Executor Service
   (Wallet A)    ────┐       (Wallet B)    ────┐      (Wallet C)
                     │                          │
                     ├──►  Multi-sig Contract  ◄┤
                     │                          │
                     └──►  On-chain Execution  ◄┘

This distributed approval architecture ensures no single point of failure can execute unauthorized rebalancing.

Security Features:

• Service Isolation: Each service runs independently with separate wallets

• Independent Validation: Approver independently verifies Proposer's work

• Threshold Signatures: Requires multiple approvals before execution

• Rate Limiting: Prevents rapid successive rebalancing

• Fail-safes: Automatic circuit breakers if anomalies detected
