Secure, non-custodial wallet infrastructure for Ethereum, Polygon, Solana, and Base. Supports ERC-721, ERC-1155, and SPL standards with unified API access.
Regulatory Compliance Framework
Pre-built integrations for travel rule solutions (TRUST, Notabene), AML screening, and KYC/onboarding. SOC 2 Type II certified infrastructure.
Enterprise-Grade Key Management
Hardware Security Module (HSM) backed, multi-party computation (MPC) wallets with customizable approval policies and transaction signing workflows.
Real-Time Portfolio & Reporting API
Comprehensive REST and WebSocket APIs for real-time NFT holdings, transaction history, tax lot accounting, and automated regulatory reporting.
Business Outcomes for Your Platform
Our institutional NFT custody integration delivers measurable results, from accelerated time-to-market to hardened security, designed for regulated entities and high-value collections.
Accelerated Time-to-Market
Deploy a fully integrated, compliant custody solution in under 4 weeks, not months. We provide pre-audited smart contracts and battle-tested APIs to integrate directly into your existing platform.
Enterprise-Grade Security & Compliance
Multi-signature, MPC-based key management with SOC 2 Type II principles. Supports institutional workflows like transaction policy engines, role-based access control, and comprehensive audit trails.
Seamless Multi-Chain Support
Unified API for managing NFTs across Ethereum, Polygon, Solana, and other major L1/L2 networks. Eliminate the complexity of managing separate integrations for each blockchain.
Operational Efficiency & Cost Reduction
Automate custody operations and reduce manual overhead by up to 70%. Our infrastructure handles gas optimization, batch transactions, and wallet management, lowering your total cost of ownership.
Enhanced Client Trust & Liquidity
Offer your institutional clients a secure, insured custody solution for blue-chip and bespoke NFT collections. Enable new revenue streams like staking, fractionalization, and collateralized lending.
Build vs. Buy: Custody Integration Paths
Compare the total cost, risk, and time investment of developing a compliant NFT custody solution in-house versus leveraging Chainscore's battle-tested platform.
| Key Factor | Build In-House | Integrate with Chainscore |
|---|---|---|
Time to Production | 9-18 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $25K - $100K |
Annual Maintenance & Ops | $150K - $300K | Optional SLA from $50K/year |
Security & Audit Burden | High (Your team's responsibility) | Low (Pre-audited, SOC 2 Type II compliant) |
Regulatory Compliance (e.g., Travel Rule) | Your team's research & implementation | Built-in, configurable modules |
Multi-Chain Support (EVM, Solana, etc.) | Per-chain development required | Unified API, out-of-the-box |
Team Requirements | 5-10 senior blockchain engineers | 1-2 integration engineers |
Key Management (HSM, MPC) | Complex procurement & integration | Enterprise-grade, provided infrastructure |
Disaster Recovery & SLAs | You design, build, and monitor | Guaranteed 99.95% uptime with defined RTO/RPO |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $75K - $150K |
Our Integration Methodology
A structured, security-first approach to integrating institutional-grade NFT custody, designed to minimize risk and accelerate your time-to-market.
Architecture & Security Review
We conduct a comprehensive audit of your current infrastructure and threat model, delivering a tailored security architecture blueprint. This ensures compliance with institutional standards before a single line of code is written.
Multi-Sig Wallet Integration
Implement customizable multi-signature schemes (e.g., 2-of-3, 3-of-5) using industry-standard smart contracts (Gnosis Safe). We configure approval workflows that match your organizational governance.
Custody API & SDK Deployment
We deploy and configure our battle-tested REST APIs and client SDKs for secure asset transfer, balance inquiry, and transaction signing. Includes comprehensive documentation and code samples.
Compliance & Monitoring Layer
Integrate real-time transaction monitoring, address screening (OFAC), and automated reporting tools. We set up alerts for suspicious activity and generate audit trails for regulatory requirements.
Staging & Penetration Testing
Deploy the full solution in an isolated staging environment. We conduct internal penetration tests and facilitate third-party audits to validate security posture before mainnet launch.
Production Launch & Support
We manage the mainnet deployment, including key ceremony and final configuration. Post-launch, we provide 24/7 technical support and incident response, backed by a 99.9% uptime SLA.
Custom Blockchain Development
End-to-end blockchain solutions from protocol design to production deployment.
We architect and build custom Layer 1/Layer 2 chains and private consortium networks tailored to your specific transaction volume, privacy, and governance needs. Our full-stack development delivers a production-ready blockchain in 8-12 weeks.
From a bespoke EVM-compatible chain for a DeFi protocol to a permissioned Hyperledger Fabric network for enterprise asset tracking, we handle the entire lifecycle.
- Core Protocol Development: Consensus mechanisms (
PoS,PoA), tokenomics, and governance models. - Node Infrastructure: Deployment, orchestration, and monitoring of validator/peer nodes.
- Interoperability: Secure bridges and cross-chain communication layers using
WormholeorAxelar. - DevOps & Tooling: RPC endpoints, block explorers, and wallet integrations for your ecosystem.
Frequently Asked Questions
Answers to common technical and operational questions about integrating secure, compliant NFT custody for your institution.
A standard integration with our custody SDK and APIs takes 2-4 weeks from kickoff to production deployment. This includes environment setup, smart contract whitelisting, multi-signature wallet configuration, and compliance rule definition. Complex requirements like custom settlement logic or support for novel token standards (ERC-6551, ERC-404) may extend the timeline, which we scope and quote for upfront.
