DESIGN PRINCIPLES
Architecture for Cross-Chain Consistency
Our oracle architecture is engineered for deterministic, verifiable data delivery across EVM and non-EVM chains, ensuring your RWA valuations are synchronized and tamper-proof.
01
Multi-Layer Data Aggregation
We implement a primary-secondary oracle model with on-chain consensus. Data is sourced from 12+ institutional-grade providers, aggregated via a proprietary median algorithm, and validated by a decentralized network of node operators before final attestation.
12+
Data Sources
3-Layer
Validation
02
Deterministic Finality & State Proofs
Leverage zero-knowledge state proofs (zk-SNARKs) and optimistic verification to guarantee data consistency. Our architecture provides cryptographic proof that the valuation delivered on Chain A is identical to the value on Chain B, eliminating reconciliation risk.

Gas-Optimized Cross-Chain Messaging
Built on established interoperability protocols (LayerZero, Axelar, Wormhole) with custom gas management logic. We batch updates and schedule deliveries during low-fee periods, reducing your operational costs by up to 40% versus naive implementations.

Business Outcomes: Secure & Scalable RWA Operations
Our Cross-Chain RWA Valuation Oracle delivers more than data—it provides the foundational infrastructure for compliant, capital-efficient, and future-proof financial products.
01
Institutional-Grade Data Integrity
On-chain verification of off-chain RWA data (appraisals, legal titles, cash flows) via a multi-signer network, ensuring tamper-proof valuations for lending, trading, and compliance.

Cross-Chain RWA Oracle FAQs
Answers to the most common questions from CTOs and product leads evaluating oracle infrastructure for real-world asset tokenization.
Our standard delivery framework is 4-6 weeks from kickoff to mainnet deployment. This includes a 1-week discovery and design phase, 2-3 weeks of core development and testing, and a final week for security review and deployment orchestration. For complex multi-asset, multi-chain deployments, timelines extend to 8-10 weeks. We provide a detailed project plan with weekly milestones.
