STRATEGIC ADVANTAGES
Business Outcomes: Why Build a Custom Storage Proof Protocol
A purpose-built storage proof protocol is a core infrastructure investment. It moves you from relying on third-party oracles to owning a critical, verifiable data layer that unlocks new business models and operational efficiencies.
01
Unlock New Revenue Streams
Move beyond basic DeFi to build novel applications like on-chain credit scoring, real-world asset tokenization, and verifiable data marketplaces. A custom protocol enables unique business logic for monetizing verified off-chain data.
New Verticals
RWA, Social, Gaming
Direct Monetization
Data as a Product
02
Eliminate Oracle Dependence & Costs
Reduce reliance and recurring fees from generalized oracle networks. A custom protocol provides cost-predictable, application-specific data feeds with tailored security and latency guarantees, cutting long-term operational expenses.

Cost Reduction
Predictable Pricing
No Per-Call Fees
03
Achieve Unmatched Data Integrity
Guarantee the provenance and immutability of off-chain data with cryptographic proofs directly verified on-chain. This builds unparalleled trust for applications in finance, compliance, and identity, backed by formal verification of the proof logic.

Frequently Asked Questions
Get clear answers on our process, security, and timelines for designing and implementing custom EVM-based storage proof protocols.
Our engagement follows a structured 4-phase process: 1. Discovery & Scoping (1-2 weeks): We analyze your use case, data sources, and security requirements. 2. Architecture Design (2-3 weeks): We deliver a detailed technical specification, including proof circuits, on-chain verifier logic, and integration points. 3. Implementation & Audit (4-8 weeks): Our team builds and internally tests the protocol. We then facilitate a formal audit with a top-tier firm like Spearbit or Zellic. 4. Deployment & Support: We assist with mainnet deployment and provide 90 days of post-launch support. We begin with a fixed-price discovery phase to ensure alignment before proceeding.
