🏗 EURG Architecture

🏗 Architecture

Smart Contract Architecture

EURG operates on a modular smart contract framework that ensures minting integrity, on-chain transparency, and seamless DeFi integration.

Module	Function
Mint/Burn	Controls creation and destruction of EURG; enforces reserve integrity
ReserveRegistry	Maps real-world vault certificates to on-chain balances
Oracle	Chainlink-based gold/silver + FX price feeds
VaultRouter	Routes mint/redeem events; creates IPFS proofs and on-chain hash anchors
DAO Module	Governs protocol settings via proposals and token voting

All contracts are ERC-20 compatible and audited for security and upgradeability.

Network Deployment

Chain	Status	Notes
HF RealX	✅ Mainnet	Primary launch platform
Arbitrum	🔜 Coming Soon	L2 efficiency + DeFi composability
Ethereum	🔜 Coming Soon	L1
Polygon	🔜 In Progress	Broad retail and ecosystem reach

All chains are synchronized through LayerZero / CCIP messaging for consistent state and mint/burn tracking.

Cross-Chain Logic

To ensure consistency and prevent double issuance, EURG uses canonical minting via trusted LayerZero endpoints. Each burn on one chain triggers a cross-chain proof that authorizes minting on the destination chain.

• xGOLD/xSILVER also support cross-chain transfer and LP deployment

• Each chain maintains a synchronized PoR registry linked to IPFS

• Governance votes and execution logic are replicated across chains

---

Proof-of-Reserve (PoR)

Every EURG minted is backed by a matching real-world asset entry on-chain:

• IPFS-stored vault certificates (hashed on-chain)

• Chainlink PoR view of xGOLD / xSILVER balances

• Live API feeds available for dApps & explorers

Quarterly audits by independent firms (e.g., Big Four or metals auditing partners) are uploaded to IPFS and linked to smart contracts.

Developer Integrations

We offer standardized interfaces for easy integration across DeFi and institutional applications:

• GET /metal-holdings → Query gold/silver backing for any wallet

• GET /eurg-price → Real-time value with Chainlink data

• POST /mint-request → Initiate on-chain mint from off-chain EUR/USDT

• DAO.vote(proposalId) → Participate in protocol governance

All endpoints and contracts are fully open-sourced and documented.
