Secure, production-ready smart contracts built by Web3 specialists to power your decentralized applications.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our development process is built on a foundation of audited code patterns and comprehensive testing to ensure reliability from day one.
Deploy with confidence, backed by rigorous security practices and battle-tested architecture.
Our development stack and process:
Solidity 0.8+ with Hardhat or Foundry. Support for Rust (Solana, CosmWasm) and Move (Aptos, Sui).OpenZeppelin standards, integration of upgradeability patterns (TransparentProxy, UUPS), and pre-audit internal reviews.Typical outcomes for our clients:
We provide the production-ready SDKs, APIs, and security infrastructure so you can launch a secure, multi-chain wallet in weeks, not years. Focus on your product, not the underlying complexity.
Launch with support for EVM, Solana, and Bitcoin from day one. Our unified SDK handles key management, transaction signing, and RPC connectivity, reducing integration time by 80%.
MPC-based key management with customizable signing policies. All infrastructure is SOC 2 Type II compliant and undergoes regular third-party security audits by firms like Halborn.
Eliminate user friction with seamless gas fee experiences. Our Paymaster API enables gasless transactions, sponsored gas, and fee payment in any ERC-20 token.
Keep users engaged with instant alerts for deposits, withdrawals, and NFT mints. Our webhook system delivers events to your backend with 99.9% reliability.
Get isolated, dedicated nodes for maximum performance and a 24/7 technical support team. We guarantee 99.95% uptime SLA and provide direct engineer access.
Our Mobile Wallet as a Service delivers specific, measurable outcomes that accelerate your product roadmap and reduce technical risk.
Deploy a production-ready, branded mobile wallet in weeks, not months. We provide the complete SDK, backend infrastructure, and security framework so your team can focus on core product logic.
Built on MPC (Multi-Party Computation) custody with institutional key management. Our architecture is designed for SOC 2 Type II readiness and integrates with leading KYC/AML providers.
Support EVM, Solana, and Bitcoin networks out-of-the-box. We handle gas abstraction, cross-chain bridging interfaces, and native token management for a unified user experience.
Eliminate the overhead of managing node infrastructure, transaction relayers, and gas fee engines. Our service model converts fixed engineering costs into predictable operational expenses.
Handle high-volume DeFi, NFT, and payment transactions with sub-second confirmation times. Our system auto-scales to support user growth and peak trading activity without service degradation.
Integrate swap aggregators, staking interfaces, and NFT marketplaces directly into your wallet. We provide pre-built modules for token swaps, portfolio tracking, and collectible display.
Choosing between building a mobile wallet from scratch or using a managed service impacts your time-to-market, security posture, and total cost of ownership. This table compares the key factors.
| Factor | Build In-House | Chainscore Wallet-as-a-Service |
|---|---|---|
Time to Market | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $500K+ | $25K - $75K (setup + first year) |
Security & Audit Burden | High (Your team's responsibility) | Managed (Pre-audited, secure MPC/TSS vaults) |
Key Management Complexity | Critical (HSM integration, key rotation) | Abstracted (Non-custodial MPC with user recovery) |
Multi-Chain Support (EVM/SVM) | Custom integration per chain | Native support for 15+ chains (Ethereum, Solana, etc.) |
Ongoing Maintenance & Updates | Full-time dedicated team | Included in service (protocol upgrades, SDK updates) |
Compliance & KYC Tools | Build or integrate third-party | Integrated modular suite (KYC, transaction screening) |
Total Cost of Ownership (Year 1) | $400K - $750K+ | $50K - $150K |
Primary Risk | Project delays, security vulnerabilities, talent retention | Vendor lock-in, service dependency |
A structured, sprint-based approach designed for technical leaders. We provide clear milestones, weekly demos, and guaranteed SLAs to ensure your mobile wallet launches on time and performs as expected.
We conduct a 2-week technical deep-dive to define your wallet's core architecture, token standards (ERC-20/721/1155), and integration points with your existing backend. Deliverables include a detailed technical spec and project roadmap.
Our battle-tested, audited SDKs for iOS and Android are integrated into your app. Includes secure key management, multi-chain RPC connectivity, and pre-built UI components for swaps, NFTs, and transactions.
We build and test your unique wallet features: custom gas policies, enterprise admin dashboards, cross-chain bridging interfaces, or proprietary DeFi integrations. All code follows OpenZeppelin security patterns.
Every module undergoes unit, integration, and penetration testing. Our security review includes automated analysis and manual code review by our senior engineers to identify vulnerabilities before launch.
We deploy a full staging environment mirroring production. You receive documentation and conduct hands-on testing. We support your QA cycle with dedicated engineering resources to address feedback.
We manage the production deployment and provide 24/7 monitoring with a 99.9% uptime SLA for our infrastructure. You receive a launch report and ongoing performance dashboards.
End-to-end development of secure, scalable blockchain applications tailored to your business logic.
We architect and build production-ready systems from the ground up. Our team delivers complete solutions—from smart contract logic and protocol design to front-end dApps and backend infrastructure—ensuring seamless integration and faster time-to-market.
