overview
SECURE FOUNDATIONS
Smart Contract Development
Production-ready smart contracts built for security, scalability, and seamless integration.
- Custom Logic:
Solidity/Rustdevelopment for DeFi protocols, NFT marketplaces, DAOs, and enterprise applications. - Security First: Adherence to OpenZeppelin standards, formal verification, and comprehensive unit/integration testing.
- Gas Optimization: Expert-level techniques to minimize transaction costs and maximize user adoption.
- Full Lifecycle: From initial design and development to deployment, verification, and ongoing maintenance on EVM, Solana, or other L1/L2 networks.
We don't just write code; we build the resilient, verifiable backbone your dApp needs to scale with confidence.

ENGINEERED FOR SCALE
Core SDK Capabilities
Our Multi-Chain Account Abstraction SDK delivers production-ready infrastructure, not just a toolkit. We handle the complexity so your team can focus on building your product.
01
Unified Multi-Chain API
A single, consistent API to manage user accounts and transactions across Ethereum, Polygon, Arbitrum, and Base. Eliminate the need to write and maintain separate integrations for each chain.

KEY DIFFERENTIATORS
Why Neo-Banks Choose Our SDK
Our Multi-Chain Account Abstraction SDK is engineered for the specific compliance, performance, and user experience demands of modern neo-banking platforms.
The Infrastructure Decision Matrix
Build In-House vs. Use Chainscore SDK
A technical and financial comparison of developing a custom multi-chain Account Abstraction stack versus integrating our production-ready SDK.
| Key Factor | Build In-House | Chainscore SDK |
|---|---|---|
Development Timeline | 6-12+ months | 4-8 weeks |
Initial Engineering Cost | $250K - $600K+ | $0 (SDK License) |
Security & Audit Overhead | High (Unaudited Risk) | Low (Pre-Audited, OpenZeppelin) |
Supported Chains (Out-of-box) | Your team builds per chain | Ethereum, Polygon, Arbitrum, Base, Optimism |
Smart Wallet Features (ERC-4337) | Custom implementation | Bundler, Paymaster, Factory, full stack |
Gas Sponsorship & Session Keys | Requires custom Paymaster logic | Built-in with configurable policies |
Ongoing Maintenance & Upgrades | Full team required | Managed by Chainscore, optional SLA |
Time to First User Onboarding | Post-development (6+ months) | Day 1 of integration |
Total Cost of Ownership (Year 1) | $300K - $750K+ | $50K - $150K (Support & SLA) |
Core Team Focus | Infrastructure development | Product differentiation & user growth |

PREDICTABLE & TRANSPARENT
Our Delivery Process
A streamlined, four-phase methodology designed for technical leaders. We deliver production-ready multi-chain account abstraction SDKs with clear milestones, predictable timelines, and zero surprises.
01
Phase 1: Architecture & Scoping
We conduct a deep technical discovery to define your target chains (EVM, Solana, Cosmos), user operations, and gas sponsorship models. Deliverables include a detailed technical spec and a fixed-scope project plan.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists.
We architect and deploy custom Solidity and Rust smart contracts with enterprise-grade security as the foundation. Every contract undergoes formal verification and multi-audit processes before mainnet deployment.
- Custom Logic: Tailored
ERC-20,ERC-721, andERC-1155implementations for tokens, NFTs, and marketplaces. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield optimizers.
- Gas Optimization: Code reviews and patterns to reduce execution costs by up to 40%.
- Full Audit Trail: Comprehensive documentation and
Foundry/Hardhattest suites included.
From a 2-week MVP to a complex multi-chain protocol, we deliver battle-tested code that executes as intended.
