ARCHITECTURE
Core Synchronization Capabilities
Our modular, protocol-agnostic infrastructure provides the foundational building blocks for seamless cross-chain user experiences. We handle the complex orchestration so you can focus on your product.
01
Unified Account Abstraction
Deploy a single, non-custodial smart account that operates natively across Ethereum, Polygon, Arbitrum, and Base. Users sign once, and our system manages all cross-chain interactions under the hood.

02
Real-Time State Mirroring
Automatically synchronize balances, NFT holdings, and transaction history across connected chains. Our low-latency indexers provide sub-2-second updates for a consistent user interface.

Data Integrity
03
Atomic Cross-Chain Actions
Enable complex, multi-step transactions that execute atomically across multiple blockchains. Bridge assets, swap on a DEX, and stake in a yield farm—all in one user-confirmed action.

TANGIBLE RESULTS
Business Outcomes for Your NeoBank
Cross-chain account synchronization is more than a technical feature—it's a strategic asset. Here are the measurable outcomes you can expect when partnering with Chainscore Labs.
01
Unified Customer Identity
We deliver a single, persistent identity for your users across Ethereum, Solana, and Polygon. This eliminates fragmented user data, enabling holistic KYC/AML compliance and personalized financial products across all chains.
1 Identity
Across All Chains
0 Duplicate KYC
Per User
02
Real-Time Portfolio Aggregation
Our synchronization engine provides sub-5-second updates on user holdings, DeFi positions, and NFT collections from multiple chains. This powers dynamic dashboards, real-time risk assessment, and automated reporting for your compliance team.
< 5 sec

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver robust cross-chain synchronization through a structured, security-first process that ensures reliability from design to deployment.
01
Architecture & Design Review
We begin with a comprehensive analysis of your multi-chain architecture, mapping account states and defining the synchronization logic for assets, NFTs, and identity data. This phase establishes the security model and gas optimization strategy.

Secure Smart Contract Development
Our engineers build and test the core synchronization contracts using battle-tested libraries like OpenZeppelin. We implement secure bridging patterns, state verification, and fail-safe mechanisms for each supported chain (EVM, Solana, Cosmos).

Frequently Asked Questions
Get clear answers on how we deliver secure, seamless state synchronization across blockchains for your application.
A standard implementation for a single source and destination chain takes 2-4 weeks from kickoff to production deployment. This includes design, development, security review, and integration testing. Complex multi-chain setups or custom bridging logic can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial consultation.
