Cross-Chain Encrypted Vault Integration

We design and implement systems that allow encrypted data vaults to operate seamlessly across multiple blockchain ecosystems, enabling unified data access and management for your application.
Chainscore © 2026
overview
SECURE, AUDITED CODE

Custom Smart Contract Development

Production-ready smart contracts built with enterprise-grade security and gas optimization.

We architect and deploy custom Solidity/Rust smart contracts for DeFi, NFTs, and enterprise applications. Every contract undergoes a multi-stage audit process with automated testing, manual review, and formal verification to eliminate vulnerabilities before mainnet deployment.

  • Gas-Optimized Architecture: Reduce user transaction costs by up to 40% with efficient storage patterns and bytecode optimization.
  • Upgradeable & Modular: Implement ERC-2535 Diamonds or Transparent Proxies for seamless, secure future upgrades.
  • Compliance Ready: Integrate ERC-20, ERC-721, ERC-1155 standards with custom logic for tokenomics, vesting, and access control.

Deliver a secure, audited MVP in as little as 2-3 weeks, backed by a 99.9% uptime SLA for deployment and maintenance.

PROVEN FRAMEWORK

Our Delivery Methodology

A structured, security-first approach to delivering production-ready cross-chain vaults. We focus on predictable timelines, audited code, and seamless integration.

01

Architecture & Strategy Session

We begin with a deep technical discovery to define your vault's multi-chain logic, threat model, and key management strategy. This ensures alignment on security requirements and integration scope from day one.

Smart Contract Development & Internal Audit

Our engineers build your vault core and relayers using battle-tested patterns (e.g., Axelar GMP, LayerZero OFT). Every line of code undergoes rigorous internal review against our security checklist before external audit.

External Security Audit & Remediation

We engage top-tier audit firms (e.g., Trail of Bits, Quantstamp) for an independent review. All findings are prioritized, remediated, and verified, with a final report provided for your compliance.
