Browser Extension Wallet Integration
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Protocols & Standards:
ERC-20,ERC-721,ERC-1155,ERC-4626, and custom logic. - Security First: Built with
OpenZeppelinlibraries and formal verification patterns. - Deliverables: Full test suites, deployment scripts, and technical documentation.
We deliver contracts you can trust, with a focus on mainnet resilience and long-term maintainability.
Core Integration Capabilities We Deliver
We architect, build, and maintain the secure wallet integrations that power your Web3 product. From initial POC to global scale, our solutions are engineered for security, performance, and seamless user experience.
Multi-Chain Wallet Connectivity
Seamless integration with MetaMask, WalletConnect, Coinbase Wallet, and Phantom. We implement the latest EIP-6963 standard for multi-injection awareness, ensuring compatibility and preventing conflicts across all major EVM and non-EVM chains.
Secure Transaction & Signing
Robust handling of EIP-712 typed data signing, message signing, and transaction simulation. We implement security best practices to prevent phishing, replay attacks, and ensure clear user consent for every on-chain action.
Real-Time State & Event Management
Live synchronization of account balances, network changes, and token approvals. Our event-driven architecture provides instant UI updates for chain switches, account changes, and transaction confirmations with sub-second latency.
Custom Provider & RPC Abstraction
Build a unified, maintainable interface over disparate wallet providers. We abstract provider-specific quirks into a clean, consistent API, simplifying your application logic and future-proofing against wallet SDK changes.
Gas Optimization & Fee Management
Intelligent gas estimation, fee market data integration (EIP-1559), and transaction bundling. We reduce failed transactions and optimize costs by dynamically adjusting to network conditions, improving user success rates.
Compliance & Audit-Ready Code
Enterprise-grade codebase with comprehensive unit/integration tests, TypeScript coverage, and security audit preparation. We deliver documented, modular code that meets SOC 2 and financial compliance requirements for institutional clients.
Business Outcomes of Deep Wallet Integration
Integrating a browser extension wallet is more than a feature—it's a strategic business decision. We deliver secure, seamless wallet experiences that directly impact your bottom line and user growth.
Accelerated User Onboarding
Reduce first-time user friction by 70% with one-click wallet connections. We implement MPC-based social logins and passkey authentication to onboard users in under 30 seconds, without seed phrase complexity.
Enhanced Transaction Security & Trust
Build user confidence with enterprise-grade security. Our integrations include transaction simulation, clear signing, and real-time risk analysis to prevent malicious approvals, backed by SOC 2 Type II compliant infrastructure.
Increased User Engagement & Retention
Drive consistent platform usage with seamless cross-session state management. Users stay logged in across browser sessions, enabling instant interactions that boost daily active users and session duration metrics.
Reduced Support & Operational Costs
Minimize wallet-related support tickets by 90% with intuitive UX patterns and proactive error handling. Our modular architecture ensures easy maintenance and updates, cutting long-term development costs.
Multi-Chain Scalability & Future-Proofing
Deploy a single integration that works across EVM, Solana, and Cosmos chains. Our abstraction layer lets you add new networks in days, not months, ensuring your platform scales with the ecosystem.
Actionable User Insights & Analytics
Gain deep visibility into wallet interactions, gas spending patterns, and feature adoption. Our integration surfaces anonymized, privacy-first analytics to inform product decisions and optimize conversion funnels.

Our Secure, Iterative Development Process
We build and integrate secure browser extension wallets using a phased, client-focused approach that minimizes risk and accelerates your time-to-market.
Architecture & Threat Modeling
We begin with a comprehensive security-first design, analyzing attack vectors for your specific use case (DeFi, NFT, payments). This includes defining key storage, transaction signing flows, and permission models to prevent common vulnerabilities.
Modular MVP Development
We deliver a functional core wallet (key management, network switching, basic transactions) in 2-3 weeks. This allows for immediate user testing and stakeholder feedback before investing in advanced features.
Security Audit & Penetration Testing
Every iteration undergoes rigorous internal review and automated analysis. For production releases, we facilitate audits with leading firms like Trail of Bits or ConsenSys Diligence to ensure institutional-grade security.
Integration & Staging Deployment
We seamlessly integrate the wallet with your dApp frontend and backend services. A full staging environment mirrors production, allowing for end-to-end testing of connect, sign, and send flows before go-live.
User Feedback & Feature Iteration
Using data from your beta users, we prioritize and develop advanced features like multi-chain support, DeFi aggregator hooks, or institutional custody integrations in focused, 2-week sprints.
Production Launch & Monitoring
We manage the store deployment (Chrome Web Store, Firefox Add-ons) and establish real-time monitoring for transaction success rates, error logging, and anomaly detection to ensure 99.9%+ reliability post-launch.
Frequently Asked Questions on Wallet Integration
Get clear answers on timelines, security, and process for integrating a secure, user-friendly browser extension wallet into your Web3 application.
A standard, production-ready browser extension wallet integration takes 4-6 weeks from kickoff to deployment. This includes architecture, core wallet functionality (key management, transaction signing), multi-chain support, and security audits. Complex features like MPC, account abstraction, or custom DeFi integrations can extend the timeline to 8-12 weeks. We provide a detailed project plan with milestones in the first week.
