Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect, develop, and audit custom Solidity/Rust smart contracts that form the immutable backbone of your application. Our development process is built for security and scale from day one.
Deploy with confidence using battle-tested code that has secured over $50M in on-chain value.
OpenZeppelin integration to deployment and verification on EVM/Solana/Aptos.Our engineers specialize in complex DeFi primitives (AMMs, lending/borrowing), ERC-20/721/1155 tokens, DAO governance systems, and cross-chain bridges. We deliver production-ready contracts within 2-4 weeks for most MVPs.
Our EVM wallet onboarding flows are engineered for security, speed, and scale. We deliver production-ready solutions that reduce user drop-off and accelerate your time-to-market.
Deploy ERC-4337 Account Abstraction with custom logic for social recovery, session keys, and batched transactions. We implement gas sponsorship models and paymaster integrations to eliminate friction for end-users.
Seamless integration with EVM L1/L2 networks (Ethereum, Arbitrum, Polygon, Base). We implement chain-agnostic signers and unified state management for a consistent user experience across ecosystems.
All smart contracts and integration layers undergo rigorous security review. We follow OpenZeppelin standards and can facilitate third-party audits with firms like Trail of Bits or ConsenSys Diligence.
Pre-built, white-label React components for wallet connection, transaction signing, and asset management. Fully customizable to match your brand, with built-in error handling and real-time state feedback.
Implement batch transactions, gas estimation caching, and intelligent fee market strategies. Reduce user transaction costs by up to 40% through optimized contract logic and L2 deployment.
Our EVM wallet onboarding flow design delivers quantifiable improvements in user acquisition, security, and operational efficiency. See the metrics that matter to your business.
We design flows that reduce friction, leading to higher completion rates for wallet creation and funding. This directly impacts your user growth and retention metrics.
Our flows integrate best practices like social recovery, MPC, and phishing protection, reducing support tickets and liability from user errors.
We deliver production-ready, modular SDKs and APIs for EVM chains, cutting your internal engineering time and accelerating your go-to-market.
Intuitive, self-service flows with clear error handling and in-app guidance drastically reduce the volume of user support requests and associated costs.
A cost and capability comparison between developing a custom wallet onboarding flow in-house versus partnering with Chainscore Labs for a specialized, production-ready solution.
| Key Factor | Build In-House | Generic Solution | Chainscore Specialized Design |
|---|---|---|---|
Time to Production | 4-8 months | 2-4 months | 4-8 weeks |
Initial Development Cost | $120K - $300K+ | $15K - $50K | $40K - $100K |
Security & Audit Overhead | High (unaudited, custom code) | Medium (generic, often unaudited) | Low (pre-audited patterns, security review) |
User Experience (UX) Quality | Variable (depends on team) | Low (one-size-fits-all) | High (user-tested, conversion-optimized) |
Multi-Chain & Protocol Support | Custom integration per chain | Limited (often single-chain) | Native (Ethereum, Polygon, Arbitrum, Base, etc.) |
Ongoing Maintenance Burden | Full responsibility for your team | Vendor-dependent, limited control | Optional SLA with dedicated support |
Custom Feature Flexibility | Full control, high cost to change | Very limited | Tailored to your tokenomics & product |
Compliance & Gas Optimization | Manual research & implementation | Basic, not optimized | Built-in (ERC-4337, gas sponsorship patterns) |
Total Cost of Ownership (Year 1) | $200K - $500K+ | $30K - $80K | $60K - $150K |
We de-risk your wallet integration with a structured, milestone-driven approach. Each phase delivers clear value and technical artifacts, ensuring alignment and predictable outcomes from discovery to launch.
We conduct a deep-dive technical audit of your existing stack and user journey to define the optimal wallet architecture. Deliverables include a comprehensive technical specification, gas cost analysis, and a detailed project roadmap.
Our engineers build and integrate the core wallet logic, including secure key management, transaction signing, and custom smart contracts (ERC-4337 Account Abstraction, multi-sig, gas sponsorship). All code follows OpenZeppelin standards.
Your wallet module undergoes rigorous internal testing and a formal security audit by our partners. We deploy to a staging environment for full integration testing, user acceptance testing (UAT), and performance benchmarking.
We manage the production deployment, configure monitoring (alerting for failed txs, gas spikes), and provide comprehensive documentation. Includes 30 days of post-launch support with a 4-hour SLA for critical issues.
Common questions from CTOs and product leads about designing secure, scalable wallet onboarding flows for Web3 applications.
A complete design-to-deployment cycle typically takes 3-6 weeks. This includes a 1-week discovery and audit phase, 1-2 weeks for UX/UI design and smart contract development, 1 week for integration, and 1-2 weeks for security review and testing. For standard flows (like social login + MPC), we can deliver a production-ready MVP in under 3 weeks.
