SECURE DATA FEEDS FOR AA WALLETS
Our MEV-Resistant Oracle Design Capabilities
We architect oracle solutions that protect AA-powered applications from front-running, sandwich attacks, and data manipulation, ensuring fair execution and predictable costs for your end-users.
01
Commit-Reveal Schemas
We implement cryptographic commit-reveal patterns to decouple data submission from publication, making oracle updates unpredictable and un-exploitable by MEV bots.

TANGIBLE RESULTS
Business Outcomes of MEV-Protected Oracles
Integrating MEV-protected oracles with account abstraction delivers measurable improvements to your protocol's security, user experience, and bottom line. Here are the concrete outcomes you can expect.
01
Eliminate Front-Running Losses
Our oracles use private mempool submission and cryptographic commit-reveal schemes to prevent MEV bots from exploiting price updates, protecting your users and your protocol's treasury from sandwich attacks and value extraction.

Traditional vs. Our Account Abstraction Oracle Design
How our purpose-built oracle design for Account Abstraction (ERC-4337) eliminates the security and UX limitations of traditional oracle patterns.
| Security & UX Factor | Traditional Oracle Design | Chainscore AA-Oracle Design |
|---|---|---|
User Key Compromise Risk | High (EOA private key is single point of failure) | Low (Session keys, social recovery, multi-sig policies) |
Gas Sponsorship & Bundling | Not natively supported; requires complex relayers | Native ERC-4337 Paymaster & Bundler integration |
Transaction Batching | Manual, complex, and gas-inefficient | Automatic multi-op bundling for single user operations |
Oracle Update Finality | Slow (Relies on block confirmations) | Sub-second with pre-confirmation guarantees |
Signature Flexibility | Limited to ECDSA | Any (ECDSA, BLS, MPC, Passkeys, social) |
Time to Integrate | 2-3 months for secure custom implementation | 2-4 weeks with our SDK & managed service |
Ongoing Security Burden | Your team manages key rotation & threat monitoring | Managed service with 24/7 monitoring & automatic key rotation |
Total Cost of Ownership (Year 1) | $150K+ (Dev, audit, infra, maintenance) | From $75K (Managed service with SLA) |

A PROVEN FRAMEWORK
Our Development & Integration Process
We deliver secure, production-ready account abstraction (AA) security oracles through a structured, transparent process designed for technical leaders. From initial architecture to final audit, our methodology ensures predictable timelines, zero vendor lock-in, and enterprise-grade reliability.
01
Architecture & Design Review
We conduct a deep technical assessment of your existing AA stack (e.g., ERC-4337 Bundlers, Paymasters) to design a custom oracle security model. This phase defines threat models, data sources, and integration points for maximum protection with minimal latency.

Frequently Asked Questions
Get clear answers on how we secure your oracle-powered applications with Account Abstraction.
A standard implementation for securing oracle data flows takes 2-3 weeks from kickoff to mainnet deployment. This includes designing the smart account architecture, integrating your specific data providers (e.g., Chainlink, Pyth, API3), and conducting internal security reviews. Complex multi-chain deployments or custom signature schemes may extend this to 4-5 weeks.
