overview
SECURE, AUDIT-READY CODE
Smart Contract Development
Production-grade smart contracts built for security, gas efficiency, and rapid deployment.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending platforms.
- Security First: Every contract undergoes internal review using Slither and MythX, following a formal specification to streamline third-party audits.
- Full Lifecycle: From architecture and development to deployment, verification on Etherscan, and post-launch monitoring.
We deliver audit-ready code in 2-4 weeks, reducing your time-to-market and technical risk. Our contracts power protocols securing millions in TVL.

THE CHAINSCORE ADVANTAGE
Deploy Compliant dApps Faster, With Less Operational Overhead
Our Identity Verification Oracle abstracts away the complexity of KYC/AML compliance, letting your engineering team focus on core product innovation. We handle the infrastructure, security, and regulatory logic.
01
Pre-Built Compliance Modules
Integrate KYC, AML, and sanctions screening in days, not months. Our modular API includes identity verification, document checks, and risk scoring for 200+ jurisdictions.

Build vs. Buy: Identity Verification for Smart Contracts
A technical and economic comparison of developing a custom KYC/AML oracle versus using Chainscore's managed service.
| Factor | Build In-House | Chainscore API |
|---|---|---|
Time to Initial Integration | 4-6 months | 2-4 weeks |
Initial Development Cost | $150K - $300K+ | $0 (Pay-as-you-go API) |
Compliance Coverage | Jurisdiction-specific (e.g., US, EU) | Global (100+ jurisdictions, FATF Travel Rule) |
Smart Contract Audit Burden | High (Your responsibility) | None (Pre-audited, verifiable modules) |
Uptime & Reliability SLA | Your team's responsibility | 99.9% with real-time monitoring |
Protocol Updates & Maintenance | Ongoing engineering cost | Included (Automatic, backward-compatible) |
Identity Proof Types | Limited to built integrations | Comprehensive (eIDAS, DID, Proof of Humanity, SBTs) |
Annual Total Cost of Ownership (Year 1) | $300K - $600K+ | $50K - $150K (scales with volume) |
Security & Key Management | High-risk (You manage keys/secrets) | Zero-trust architecture (No single point of failure) |

Frequently Asked Questions
Get clear answers on how we deliver secure, compliant, and scalable identity verification for your Web3 application.
An Identity Verification Oracle is a secure, off-chain service that provides verified identity data (like KYC/AML status, credential attestations, or legal jurisdiction) to on-chain smart contracts. You need one to build compliant DeFi, RWA tokenization, or regulated dApps without sacrificing decentralization. Our oracles enable features like permissioned pools, geofencing, and accredited investor checks while maintaining user privacy and data sovereignty.
