# Technology architecture

### 1. Overview

GoldBridge Alliance is built on a multi-layer technology architecture designed to support verified gold digital asset issuance, verification, bridging, swapping, and distribution at global scale.

***

### 2. Multi-Layer Architecture

| Layer                | Role                                                                  |
| -------------------- | --------------------------------------------------------------------- |
| Smart Contract Layer | GDBA token, fees, node, lock-up, and rewards contracts                |
| Bridge Layer         | Verified asset connections, swap requests, bridge status management   |
| Verification Layer   | Issuer review, audit data, KYB, AML/KYC status management             |
| Oracle / Data Layer  | Gold price, exchange rates, exchange prices, on-chain data reflection |
| Swap Pool Layer      | RWA · Stablecoin · GDBA pool management                               |
| Settlement Layer     | OTC, exchange, custody, country partner settlement                    |
| Node Layer           | Node license, contribution points, rewards management                 |
| RWA Dashboard Layer  | RWA issuance · verification · bridge status management                |
| Application Layer    | Website, member portal, operations dashboard                          |

***

### 3. Smart Contract Components

Before production deployment, the following contracts must complete design, testnet, internal testing, external audit, and multi-sig setup:

1. **GDBA Token Contract** — Token issuance, transfer, and utility functions
2. **Locking Contract** — Node lock-up and vesting schedule management
3. **Node Rewards Contract** — Contribution Point assessment and reward distribution
4. **Swap Pool Contract** — Verified asset swap pool and liquidity management

***

### 4. Security Architecture

| Security Feature              | Description                                                          |
| ----------------------------- | -------------------------------------------------------------------- |
| External Security Audit       | Required before production deployment of all smart contracts         |
| Multi-sig Controls            | All major fund movements require multi-signature approval            |
| Emergency Stop Function       | Bridge and swap operations can be halted in emergency situations     |
| Pool-Only Wallet Restrictions | Conditional issuance quantities restricted to swap pool wallets only |
| Ongoing Monitoring            | Connected assets subject to continuous automated monitoring          |

### 5. Data and Oracle Integration

| Data Type           | Source                                             |
| ------------------- | -------------------------------------------------- |
| Gold Spot Price     | International gold price feeds                     |
| Exchange Rates      | Real-time FX data                                  |
| Exchange Prices     | CEX/DEX price data                                 |
| On-chain Asset Data | Blockchain data for connected RWAs and stablecoins |

***

### 6. Key Message

> GoldBridge Alliance's technology architecture is designed with security and verification at its core. No component goes to production without passing through the full audit and multi-sig governance process.
