Institutional Cross-Chain Custody Gateway

overview

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.

We architect and deploy production-grade smart contracts that power your core business logic. Our process delivers fully audited, gas-optimized code on time, eliminating the risk of costly exploits and delays.

End-to-End Development: From initial Solidity/Rust architecture to final mainnet deployment and verification.
Security-First: Built with OpenZeppelin standards and subjected to rigorous multi-stage audits before launch.
Protocol Specialization: Expertise in ERC-20, ERC-721, ERC-1155, staking systems, DAO governance, and custom DeFi primitives.

We don't just write code; we deliver a secure, operational asset that forms the backbone of your application.

Our deliverables include comprehensive documentation, deployment scripts, and a detailed audit report, ensuring your team has full confidence and control. We focus on modular, upgradeable designs (using proxies like UUPS) to future-proof your investment.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Capabilities of Our Custody Gateway

Our gateway is engineered for institutional demands, delivering the security, compliance, and operational efficiency required to manage digital assets at scale across any blockchain.

Multi-Chain Asset Custody

Secure custody for assets across 30+ major EVM and non-EVM chains (Ethereum, Solana, Polygon, etc.) from a single, unified API. Eliminates the complexity of managing separate infrastructure for each protocol.

EXPLORE

Institutional-Grade Security

Built on a foundation of MPC (Multi-Party Computation) and HSM (Hardware Security Module) technology. All key management processes are certified to SOC 2 Type II standards, ensuring bank-level security for your private keys.

EXPLORE

Programmable Policy Engine

Define and enforce granular transaction policies (approval thresholds, whitelists, velocity limits) with smart contract-like logic. Automate compliance and governance without sacrificing operational speed.

EXPLORE

Real-Time Risk & Compliance

Continuous monitoring with AML/KYC screening, transaction simulation, and anomaly detection. Generate auditable reports for regulators and internal stakeholders on-demand.

EXPLORE

Developer-First API

RESTful API with comprehensive SDKs (Node.js, Python, Go) and detailed webhook support. Integrate custody, transaction signing, and balance queries into your existing workflows in days, not months.

EXPLORE

Dedicated Support & SLAs

24/7 technical support from our blockchain engineers and a 99.9% uptime SLA for all core services. Includes dedicated onboarding and a named technical account manager.

Infrastructure Decision Matrix

Build vs. Buy: Dedicated Gateway vs. Public Bridges

A detailed comparison of the operational, security, and cost implications of building a cross-chain custody solution in-house versus deploying Chainscore's dedicated gateway, contrasted with the risks of using public bridges.

Critical Factor	Build In-House	Chainscore Dedicated Gateway	Public Bridges
Time to Production	6-12+ months	4-8 weeks	Immediate
Initial Development Cost	$250K - $750K+	$50K - $150K	$0
Annual Maintenance & Ops Cost	$150K - $300K	Optional SLA from $60K/year	$0
Security Posture & Audit Burden	Your responsibility (High Risk)	Pre-audited, insured infrastructure (Low Risk)	Shared, opaque risk (Very High Risk)
Settlement Finality & Speed	Custom (Your team's capability)	< 2 seconds (Guaranteed SLA)	Variable (2 min - 24 hrs)
Uptime & Reliability SLA	Your team's responsibility	99.9% with 24/7 monitoring	No SLA, frequent outages
Protocol & Chain Upkeep	Manual updates required	Automated, managed by Chainscore	Dependent on third-party team
Compliance & Transaction Privacy	Custom implementation required	Built-in, institution-grade privacy	Fully transparent, public mempool
Team & Expertise Required	5-10 senior blockchain engineers	Your integration team only	None
Total Cost of Ownership (3 Years)	$700K - $1.65M+	$230K - $510K	$0 (Excluding risk)

A PREDICTABLE PATH TO PRODUCTION

Our Delivery Process: From Design to Deployment

We deliver institutional-grade custody gateways through a structured, transparent process. Every phase is designed for security, compliance, and seamless integration with your existing treasury operations.

1. Discovery & Architecture

We conduct a comprehensive technical and compliance workshop to define your multi-chain strategy, regulatory requirements, and integration points. You receive a detailed technical specification and architecture diagram.

Requirement Clarity

2. Secure Smart Contract Development

Our engineers build your custom custody logic using battle-tested patterns (e.g., MultiSig, MPC) on your chosen chains (Ethereum, Solana, Polygon, etc.). All code follows OpenZeppelin standards and is written for auditability.

Frequently Asked Questions

Get clear, technical answers about our enterprise-grade custody solution for multi-chain asset management.

Standard deployment takes 4-6 weeks from kickoff to production. This includes 2 weeks for architecture design and smart contract development, 2 weeks for integration with your existing systems and security testing, and 2 weeks for final audits and go-live. Complex integrations with proprietary vaults or custom compliance modules may extend this by 1-2 weeks.
