CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built by experts for production-grade DeFi, NFTs, and Web3 applications.
- Security-First Development: Code written in
Solidity 0.8+orRust, followingOpenZeppelinstandards and undergoing rigorous internal audits before deployment. - Full-Spectrum Contracts: From fungible (
ERC-20,SPL) and non-fungible tokens (ERC-721,ERC-1155) to complex DeFi primitives like automated market makers, staking pools, and governance systems. - End-to-End Ownership: You receive complete, commented source code, deployment scripts, and verification on block explorers—no vendor lock-in.

DESIGNED FOR SECURITY AND SPEED
Core Architecture of Our MEV-Resistant Oracle Bridges
Our bridge architecture is engineered from the ground up to protect your DeFi protocols from MEV attacks and data manipulation, delivering reliable, tamper-proof data feeds across ecosystems.
01
Multi-Layer Data Validation
We aggregate data from 50+ independent sources per feed and apply cryptographic attestations and consensus mechanisms to filter out outliers and malicious data before finalization.
50+
Data Sources
< 3 sec
Finality
02
Threshold Signature Schemes (TSS)
Data is signed by a decentralized network of nodes using distributed key generation. No single entity controls the signing key, eliminating central points of failure and censorship.

Single Points of Failure
03
Commit-Reveal Schemas for MEV Resistance
Price updates are submitted in two phases to prevent front-running. Oracles commit to hashed data first, then reveal after a random delay, making MEV extraction economically unviable.

Fallback Mechanisms & Liveness Guarantees
Automated failover to secondary data providers and consensus layers ensures 99.9% uptime. Our architecture is designed for resilience against network partitions and node failures.

Infrastructure Decision Matrix
Build vs. Buy: Custom Bridge vs. Generic Messaging Layer
A technical and financial comparison of building a custom oracle bridge with MEV safeguards in-house versus using Chainscore's managed service.
| Critical Factor | Build In-House | Generic Messaging Layer (e.g., CCIP, Wormhole) | Chainscore Managed Bridge |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 months | 4-8 weeks |
Upfront Development Cost | $250K - $600K+ | $0 (integration only) | $50K - $150K |
MEV & Front-Running Safeguards | Custom R&D required | Limited or none | Built-in with commit-reveal & encryption |
Security Posture | High risk (unaudited, novel code) | Shared risk (audited, but broad attack surface) | Dedicated risk (audited, application-specific) |
Oracle Data Integrity | Your responsibility | Provider's responsibility | Provider's responsibility with custom verification |
Cross-Chain Finality | Custom logic for each chain | Varies by provider (mins to hours) | Optimized for speed (< 2 min target) |
Ongoing Maintenance & Updates | Full-time team (2-3 engineers) | Minimal (follow provider updates) | Handled by Chainscore with SLA |
Total Cost of Ownership (Year 1) | $500K - $1M+ | $20K - $100K (fees + integration) | $80K - $200K (all-inclusive) |
Custom Logic & Business Rules | Fully customizable | Highly constrained | Tailored to your dApp's needs |
