描述
Project Overview
Ark Gold ($AGLD) is a decentralized RWA protocol that establishes a cryptographically verified link between physical gold and on-chain liquidity. Issued natively on the Mantle Network, $AGLD eliminates the "bridge risks" associated with wrapped assets and introduces the first Atomic Verification Standard for commodity tokens.
The Problem
Current gold tokens suffer from two critical flaws:
Audit Latency: They rely on monthly paper audits, creating a 30-day "blind spot" where reserves are unverified.
Bridge Risk: Most L2 gold tokens are merely "wrapped" versions of Ethereum assets. If the bridge fails, the token becomes worthless.
The Solution: Ark Gold
We replace "Post-Audit Trust" with "Pre-Validation Enforcement."
Mantle Native: Minted directly on Mantle for sub-second finality and negligible fees.
The Circuit Breaker: Our smart contract queries the Korea Gold Exchange (KGE) inventory API every 10 seconds. If
Mint Amount + Current Supply > Physical Reserve, the transaction Reverts immediately.Sovereign Custody: Backed 1:1 by Allocated Gold Bars stored in KGE’s sovereign-grade vaults, legally segregated from the custodian's balance sheet.
Key Features
🪙 Native Issuance: Zero bridge risk. Pure Mantle-native liquidity.
🛡️ Circuit Breaker: Mathematically impossible to over-mint tokens.
🔍 Proof of Reserve: Real-time on-chain verification (vs. monthly PDF reports).
🏦 Trusted Partner: Anchored by Korea’s largest precious metals distributor (KGE).
黑客松進展
During this hackathon, we built the entire Ark Gold MVP from scratch on the Mantle Sepolia Testnet. 1. Smart Contracts (Solidity): Developed the ArkGold ERC-20 contract with the core "Circuit Breaker" logic. Implemented the mint function that automatically checks on-chain Proof-of-Reserve (PoR) data before execution. Deployed and verified contracts on Mantle Sepolia. 2. Mock Oracle Infrastructure (Node.js): Built a simulation script to mimic the Korea Gold Exchange (KGE) Inventory API. Successfully implemented a logic that pushes reserve data to the smart contract every 10 seconds. 3. Frontend & Integration: Created a Web3 dashboard to visualize the Reserve vs. Supply status in real-time. Key Achievement: Demonstrated the "Transaction Revert" scenario where the system blocks minting when the physical reserve is simulated to drop.
