PROVEN PROCESS
Our Oracle Upgrade Methodology
A systematic, security-first approach to migrating your on-chain data feeds with zero downtime and guaranteed compatibility.
01
Comprehensive Audit & Gap Analysis
We perform a deep technical audit of your existing oracle integration, identifying security vulnerabilities, gas inefficiencies, and compatibility gaps with your target oracle network (e.g., Chainlink, Pyth, API3).

02
Architecture & Migration Planning
Our architects design a phased migration blueprint. We define fallback mechanisms, data consistency models, and a rollback strategy to eliminate single points of failure during the cutover.

03
Smart Contract Development & Testing
We develop and rigorously test the new oracle adapter contracts. Testing includes unit tests, integration tests with live testnet oracles, and scenario-based simulations for market volatility.

Security Review & Formal Verification
Every line of upgrade code undergoes internal review against OpenZeppelin standards. Critical financial logic is formally verified using tools like Certora or Slither to prove correctness.

GUARANTEED RESULTS
Business Outcomes: Stability, Security, Scalability
Our Oracle Upgrade & Migration Services deliver more than just technical execution. We provide measurable, production-ready outcomes that ensure your data feeds are a competitive asset, not a liability.
01
Zero-Downtime Migration
Seamless transition from legacy oracles (e.g., Chainlink V1, custom feeds) to modern, decentralized networks like Chainlink Data Feeds, Pyth Network, or API3. We guarantee no disruption to your live dApp's core functions during the cutover.

Time, Cost, and Risk Analysis
Managed Upgrade vs. In-House Execution
Compare the total cost of ownership and operational burden of managing your own oracle upgrade versus leveraging Chainscore's managed service.
| Factor | Build & Manage In-House | Chainscore Managed Service |
|---|---|---|
Time to Production | 8-16 weeks | 2-4 weeks |
Core Team Effort | 3-5 engineers, full-time | Your team provides requirements |
Security Audit | Additional $20K-$50K, 4-6 weeks | Included, with formal verification |
Deployment & Testing | Manual, high-risk process | Automated with staging environments |
Post-Launch Monitoring | Requires custom tooling & team | Included with 24/7 alerting |
Incident Response SLA | None (internal on-call) | Guaranteed < 1 hour |
Total First-Year Cost | $250K - $600K+ | $75K - $200K |
Key Risk | Unpatched vulnerabilities, downtime | Mitigated via expert SLAs |

Oracle Upgrade & Migration FAQs
Answers to the most common questions from CTOs and technical leads evaluating our Oracle upgrade and migration services.
Our standard delivery timeline is 4-8 weeks from kickoff to mainnet deployment. This includes a 1-week discovery and scoping phase, 2-4 weeks for development and internal testing, 1 week for client UAT, and a final week for deployment and documentation. Complex migrations involving multiple data feeds or custom logic may extend this timeline, which we define in a fixed-scope statement of work.
