We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our development process includes formal verification, gas optimization, and comprehensive audits to ensure security and efficiency from day one.
Multi-VM Smart Wallet SDK
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Protocols:
ERC-20,ERC-721,ERC-1155, and custom standards. - Security: Built with OpenZeppelin libraries and tested against common vulnerabilities.
- Delivery: From MVP in 2-4 weeks to full protocol suite deployment.
We deliver battle-tested code that powers real-world value, not just demo projects.
Core Technical Capabilities
Our Multi-VM Smart Wallet SDK is engineered for production-grade reliability. We deliver battle-tested modules that integrate seamlessly into your stack, reducing development time and mitigating security risks.
Enterprise-Grade Security
Built with formal verification patterns and audited by leading firms. Includes secure key management, transaction simulation, and real-time threat detection to protect user assets.
High-Performance RPC Layer
Leverage our globally distributed RPC infrastructure with load balancing, failover, and mempool prioritization. Guarantee sub-second transaction propagation and 99.9% uptime for wallet operations.
Cross-Chain Gas Management
Abstract gas complexities with sponsored transactions, gas estimation across 10+ networks, and fiat on-ramp integration. Users never need native tokens for fees.
Business Outcomes for Your Product
Our Multi-VM Smart Wallet SDK is engineered to deliver measurable improvements in user acquisition, security, and operational efficiency. Here are the concrete outcomes you can expect.
Accelerated Time-to-Market
Launch a production-ready, secure wallet experience in under 2 weeks, not months. We provide a fully integrated SDK with pre-built modules for account abstraction, social logins, and multi-chain support.
Enhanced User Security & Trust
Implement enterprise-grade security from day one. Our SDK includes battle-tested smart account logic, session key management, and is built with OpenZeppelin standards, providing a foundation users and auditors trust.
Seamless Multi-Chain Adoption
Deploy a single wallet interface that works across EVM, Solana, and Starknet without fragmented user experiences. Abstract away chain complexity to drive higher engagement and asset bridging.
Reduced Development & Maintenance Costs
Cut infrastructure and engineering overhead by up to 70%. We manage the core wallet stack, RPC nodes, gas sponsorship, and updates, freeing your team to focus on core product innovation.
Higher User Activation & Retention
Remove onboarding friction with gasless transactions, social logins, and batch operations. Proven to increase user activation rates by over 40% and improve session duration.
Enterprise-Grade Reliability
Build on infrastructure with a 99.9% uptime SLA, automatic failover, and real-time monitoring. Ensure your wallet remains operational during peak demand and network congestion.
Build vs. Buy: The Multi-VM Wallet Dilemma
Choosing between building a multi-VM wallet SDK in-house or using a proven solution like Chainscore's involves significant trade-offs in time, cost, and risk. This table compares the key factors for CTOs and technical founders.
| Key Factor | Build In-House | Chainscore SDK |
|---|---|---|
Time to First Wallet | 6-12+ months | 4-8 weeks |
Initial Development Cost | $200K - $500K+ | $50K - $150K |
Security Audit & Penetration Testing | Additional $50K-$100K & 8-12 weeks | Included & pre-audited |
Supported VMs on Day 1 | EVM only (requires roadmap for others) | EVM, SVM, MoveVM (Solana, Aptos, Sui) |
Ongoing Maintenance & Upgrades | 1-2 FTEs dedicated ($150K-$300K/year) | Handled by Chainscore team |
Compliance & Gas Abstraction | Custom build required | Built-in (ERC-4337, sponsored tx) |
Uptime & Reliability SLA | Your team's responsibility | 99.9% SLA with monitoring |
Integration Complexity | High (custom RPC, indexing, state management) | Low (single SDK, unified API) |
Total Cost of Ownership (Year 1) | $350K - $800K+ | $50K - $150K |
Our Delivery Methodology
We deliver production-ready Multi-VM Smart Wallet SDKs through a structured, transparent process designed for technical founders. Our methodology ensures security, speed, and seamless integration.
Architecture & Design Sprint
We conduct a 2-week collaborative sprint to define your wallet's core architecture, user flows, and multi-VM support (EVM, Solana, Starknet). This phase establishes a clear technical blueprint and integration roadmap.
Secure Core Development
Our engineers build the wallet's secure core modules—key management, transaction signing, and multi-chain RPC abstraction—using audited libraries and security-first patterns. Every module is unit-tested from day one.
VM-Specific Integration
We implement and test native support for your target virtual machines. This includes EVM (Ethereum, Polygon), Solana (Rust programs), and app-chains, ensuring consistent APIs and transaction finality.
Deployment & Integration Support
We provide a dedicated integration window with our engineers to deploy the SDK into your staging/production environment. Includes documentation, sample apps, and 30 days of launch support.
Ongoing Maintenance & Upgrades
Stay current with protocol upgrades and new VM integrations. Our maintenance plans include security patches, performance optimizations, and updates for new chain deployments.
Frequently Asked Questions
Get clear, technical answers about our SDK's capabilities, integration process, and support.
For a standard integration with EVM and Solana support, most teams achieve a production-ready implementation in 2-3 weeks. Complex deployments with custom transaction flows or additional VM support (e.g., Move) typically take 4-6 weeks. We provide a detailed integration roadmap during the initial technical scoping call.
