BUILT FOR SCALE AND COMPLIANCE
Why Choose Custom EVM KYC Portal Development
Generic KYC solutions create friction and risk. Our custom portals are engineered for the specific demands of EVM-based DeFi, gaming, and enterprise platforms, delivering seamless user verification that accelerates onboarding and ensures regulatory adherence.
01
Tailored Compliance Logic
We build KYC workflows that match your jurisdiction, token type, and user risk profile. Integrate specific AML rules, investor accreditation checks, and geo-blocking directly into your smart contract logic.

On-Chain Identity Verification
Move beyond basic checks. We implement verifiable credentials (VCs), soulbound tokens (SBTs), and zero-knowledge proofs (ZKPs) to create reusable, privacy-preserving identity attestations on-chain.

A PROVEN FRAMEWORK
Our Development & Compliance Methodology
We deliver production-ready EVM KYC portals by integrating secure engineering with deep regulatory expertise, ensuring you launch compliantly and scale with confidence.
03
Automated Identity Verification
Integrate leading providers (Sumsub, Onfido) or custom oracles for document checks, liveness detection, and sanction screening. We handle the complex on-chain/off-chain data flows.
04
Privacy-Preserving Design
Implement Zero-Knowledge Proofs (ZKPs) or secure enclaves for selective disclosure. Users prove compliance without exposing sensitive PII on-chain, aligning with GDPR and data sovereignty laws.
05
Real-Time Monitoring & Reporting
Get a unified dashboard for compliance oversight. Monitor verification statuses, flag suspicious activities, and generate audit trails for regulators automatically.
06
Deployment & Integration Support
We handle full-stack deployment, from smart contracts to frontend, with seamless integration into your existing wallet, DEX, or banking infrastructure. Includes comprehensive documentation and developer handoff.

FOUNDATION
Blockchain Infrastructure Development
Enterprise-grade node infrastructure, RPC endpoints, and data indexing for scalable Web3 applications.
We build and manage the foundational infrastructure your application needs to run reliably at scale. Our solutions eliminate the operational overhead of running your own nodes, letting you focus on product development.
- High-Performance RPC: Dedicated endpoints with 99.9% uptime SLA, rate limiting, and advanced caching for
EVMandSolanachains. - Managed Node Clusters: Automated deployment, monitoring, and failover for
Geth,Erigon, andSolanavalidators. - Real-Time Data Indexing: Custom subgraphs and indexers for on-chain events, providing sub-second query responses for your dApp's frontend.
- Security & Compliance: Infrastructure deployed with enterprise-grade security,
SOC 2compliance readiness, and dedicated VPCs.
Deploy production-ready infrastructure in under 2 weeks, with 24/7 monitoring and expert support included.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building a compliant KYC portal.
A standard, production-ready EVM KYC portal with core compliance features (user onboarding, document verification, on-chain attestations) typically deploys in 3-5 weeks. Complex integrations with specific AML providers or custom regulatory rule engines can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
