Technical Architecture
Overview and Design Principles PropChain’s technical architecture is meticulously designed to deliver exceptional scalability, interoperability, security, and modularity. Built to support rapid integration, expansion, and innovation our architecture ensures robust operational efficiency and compliance. Blockchain Layer
Ethereum Mainnet – primary network for PropYield (On-chain) and PROPC token including vesting contracts, staking and CCIP integration - High adoption, strong security, rich tooling, and deep DeFi integrations (PoS)
Polygon PoS – used for deploying real estate tokens following the CMTAT standard - Lower gas fees, Ethereum compatibility, supports high-volume operations for real estate token minting (PoS)
Solana – connected via Wormhole for cross-chain bridging of PROPC - Fast finality and low transaction cost; used for targeted cross-chain interoperability (PoH & PoS)
Smart Contract Infrastructure Smart contracts automate complex processes, significantly enhancing efficiency, reducing errors, and ensuring compliance.
Prochain core contracts include:
PROPC Token: ERC20 implementation on Ethereum
Staking Contracts:
Pool-based staking with fixed APYs, penalty structure, and claim locks
Multi-stake support, dynamic penalties (decreasing over time), min/max thresholds, VIP pool access
Vesting Contracts: Custom-built contracts for phased token distribution with TGE, ticks, and admin-managed liquidity
Cross-chain Bridge: Wormhole bridge to Solana for token mirroring
Swap Integration: Chainlink CCIP integrated with xSwap for token swaps across chains
Off-Chain Integrations:
Analytics Integration: CoinGecko and other market data feeds (read-side)
Oracles (Planned): Chainlink Data Feeds and potential custom off-chain valuation for real estate
Audits and Security
Audit Partner - Zokyo: Comprehensive smart contract audit including:
Line-by-line manual code review
Cross-comparison with leading DeFi contracts
Foundry-based fuzz testing and integration test coverage
Attack vector simulation and risk categorization (Critical to Informational)
100% resolved actionable issues in the report
Code testability coverage of 96% (industry-leading)
Practices:
Modular contract structure for upgradeability and minimal risk
Reentrancy guards, SafeMath, SafeERC20 utilities
PlatformAccessController for RBAC enforcement in vesting/staking
