We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on OpenZeppelin standards and rigorous security-first practices.
AppChain-Specific Wallet Connectivity Solutions
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Full Lifecycle Development: From initial architecture and
Solidity 0.8+coding to deployment onEVMchains and ongoing maintenance. - Security as Standard: Every contract undergoes internal audits, formal verification, and gas optimization before mainnet deployment.
- Protocol Integration: Seamless integration with
ERC-20,ERC-721,ERC-1155, and leading DeFi primitives like Uniswap V3 and Aave.
Deliver a secure, audited, and gas-optimized smart contract suite in 4-6 weeks, ready for mainnet launch.
Core Components of Our AppChain Connectivity Layer
Our modular, enterprise-grade connectivity stack is built to eliminate wallet integration friction, accelerate user onboarding, and ensure secure, reliable transactions on your application-specific blockchain.
Custom RPC Endpoint Orchestration
Dedicated, load-balanced RPC endpoints for your AppChain with intelligent failover and request routing. We manage node infrastructure, ensuring high availability and low-latency data access for your dApp.
Transaction Signing & Simulation Engine
Pre-flight transaction simulation to prevent user errors and failed transactions. Our engine validates gas estimates, contract interactions, and state changes before submission, reducing support tickets and improving UX.
Real-Time Chain State Synchronizer
Keeps user wallet state (balances, NFTs, allowances) in sync with your AppChain's latest blocks. Eliminates stale data issues and ensures UI consistency without manual refresh.
Developer Dashboard & Analytics
Comprehensive portal to monitor wallet connection metrics, transaction volumes, error rates, and user engagement. Gain actionable insights to optimize your onboarding funnel and infrastructure.
Business Outcomes: From Technical Spec to User Growth
We translate technical infrastructure into measurable business results. Our AppChain wallet solutions are engineered to accelerate your time-to-market, secure your assets, and drive user adoption with a seamless experience.
Rapid Time-to-Market
Deploy a production-ready, custom wallet connector for your AppChain in under 3 weeks. Our modular SDKs and pre-built components eliminate months of development time, allowing you to launch and iterate faster.
Enterprise-Grade Security
Wallet integrations built with OpenZeppelin standards and undergo rigorous internal audits. We ensure secure key management, transaction signing, and protection against common Web3 vulnerabilities from day one.
Seamless User Onboarding
Increase user activation by 40%+ with intuitive, frictionless wallet connections. Our solutions support social logins, multi-chain detection, and one-click interactions tailored to your AppChain's UX.
Multi-Chain & Cross-Chain Readiness
Future-proof your application with built-in support for EVM, Solana, and Cosmos SDK chains. Our architecture enables easy expansion, allowing your users to interact across ecosystems without re-engineering.
Real-Time Analytics & Insights
Gain actionable data on wallet adoption, transaction patterns, and user drop-off points. Integrate with your existing analytics stack to measure growth and optimize the user journey.
Dedicated Technical Partnership
Work directly with senior blockchain engineers who have deployed 50+ wallet integrations. Get architectural reviews, on-call support, and strategic guidance to scale your connectivity layer.

Our Delivery Process: From Integration to Launch
We deliver a structured, milestone-driven process for integrating secure wallet connectivity into your AppChain. From initial architecture to mainnet launch, our proven framework ensures clarity, reduces risk, and accelerates your time-to-market.
1. Architecture & Specification
We conduct a technical deep-dive to define the optimal wallet integration architecture for your AppChain's consensus, token standards, and user flows. Deliverables include a detailed technical spec and integration roadmap.
2. SDK Development & Integration
Our team builds and integrates a custom, lightweight SDK for your chain. This includes core wallet connection, transaction signing, and state synchronization, following security best practices from day one.
3. Security Audit & Penetration Testing
Every integration undergoes rigorous internal security review and optional third-party audit. We test for common vulnerabilities in key management, RPC endpoints, and transaction replay attacks.
4. Staging Deployment & QA
We deploy the integrated solution to your staging/testnet environment. Our QA engineers perform end-to-end testing across wallets (MetaMask, WalletConnect, etc.) and device types to ensure flawless performance.
5. Production Launch & Monitoring
We manage the mainnet deployment and configure real-time monitoring for connection health, error rates, and performance metrics. Includes 24/7 alerting for any critical issues post-launch.
6. Documentation & Knowledge Transfer
We provide comprehensive technical documentation and API references for your team. Includes a dedicated handover session to ensure your developers can maintain and extend the integration.
Frequently Asked Questions for Technical Leaders
Technical answers for CTOs and engineering leads evaluating wallet connectivity solutions for their custom blockchain.
We provide a standardized SDK and a suite of adapters that abstract the complexity. Our solution includes a custom RPC provider that translates standard EVM JSON-RPC calls to your chain's native execution, a wallet connector library for popular frameworks (like wagmi/viem), and a secure, hosted wallet management service. This allows users to connect MetaMask, WalletConnect, and other standard wallets without requiring them to manually add your network. We've deployed this for 30+ chains with varying consensus mechanisms.
