ENTERPRISE-GRADE IDENTITY INFRASTRUCTURE
Core Technical Capabilities We Deliver
We architect and deploy secure, scalable decentralized identity systems that verify attendees in seconds, reduce fraud, and provide a seamless user experience. Our solutions are built on proven standards and audited for enterprise adoption.
03
Zero-Knowledge Proof (ZKP) Verification
Integrate zk-SNARKs and zk-STARKs to enable selective disclosure. Verify attendee eligibility (e.g., age, membership status) without exposing underlying personal data, enhancing privacy and regulatory compliance.
04
Cross-Platform Wallet SDKs
Provide attendees with seamless login via embedded SDKs for web and mobile. Supports major wallet providers (MetaMask, WalletConnect) and passwordless Web3Auth flows, reducing onboarding friction by over 70%.
05
Real-Time On-Chain Attestation
Issue and verify immutable attestations on EVM-compatible blockchains (Ethereum, Polygon, Base). Our gas-optimized smart contracts provide a public, verifiable record of attendance and credential issuance.
06
Compliance & Audit-Ready Architecture
Build with GDPR, CCPA, and future digital identity regulations in mind. Our systems include data minimization by design, consent management logs, and full audit trails for credential lifecycle events.

DEX Development vs. Building In-House
A technical and economic comparison of developing a decentralized exchange from scratch versus leveraging Chainscore's modular DEX development platform.
| Key Factor | Build In-House | Chainscore DEX Platform |
|---|---|---|
Time to Market (MVP) | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security Audit Overhead | High (3-6 months, $50K-$150K) | Included (Pre-audited modules) |
Core Features (AMM, Order Book, Limit Orders) | Choose one, build from zero | Modular, deploy all three |
Multi-Chain Deployment (EVM & non-EVM) | High complexity, per-chain effort | Standardized, configurable deployment |
Ongoing Maintenance & Upgrades | Full internal team required | Managed service with optional SLA |
Liquidity Bootstrapping Tools | Custom build required | Integrated launchpad & incentives |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $80K - $200K |

ERC-20,ERC-721,ERC-1155with custom minting, vesting, and staking logic. - DeFi Protocols: Automated market makers (AMMs), liquidity pools, yield aggregators, and lending vaults.
- Enterprise Logic: Multi-signature wallets, DAO governance modules, and verifiable supply-chain tracking.
We deliver audit-ready code in 2-4 weeks, with a 99.9% uptime SLA for deployed contracts on EVM-compatible chains like Ethereum, Polygon, and Arbitrum.
Decentralized Identity for Events
Frequently Asked Questions
Get clear answers on how we build secure, scalable identity verification systems for conferences, festivals, and exclusive events.
We deploy a custom, event-specific identity protocol. Each attendee receives a unique, non-transferable SBT (Soulbound Token) or Verifiable Credential upon ticket purchase. At the venue, they scan a QR code with their wallet to prove ownership, granting instant, fraud-proof access. This eliminates fake tickets, reduces queue times, and provides organizers with verified, on-chain attendance data.
