We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our contracts are built with Solidity 0.8+ or Rust, following OpenZeppelin standards and security-first patterns.
AppChain Wallet Interface Design
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
- Full Lifecycle Support: From initial design and
Hardhat/Foundrydevelopment to comprehensive testing, auditing, and mainnet deployment. - Gas Optimization: We write contracts for maximum efficiency, reducing user transaction costs by up to 40%.
- Security-First: Every line undergoes peer review and is prepared for formal audits by firms like CertiK or Quantstamp.
Deploy a secure, audited MVP in as little as 2-3 weeks, with guaranteed 99.9% uptime post-launch. We ensure your core logic is immutable, efficient, and battle-tested.
Core Design Capabilities for AppChain Wallets
We deliver production-ready wallet interfaces that balance superior user experience with institutional-grade security, accelerating your AppChain's adoption.
Multi-Chain & AppChain-Specific UX
Design seamless onboarding flows for your specific AppChain, with clear guidance on gas, bridging, and network switching. We integrate with WalletConnect v2 and support custom RPC endpoints for a native feel.
Transaction Security & Simulation
Implement in-wallet transaction previews, risk warnings for contract interactions, and integration with tools like Tenderly for simulation. Reduces user error and prevents malicious drainer attacks.
Gas Optimization & Fee Abstraction
Design intuitive interfaces for gas management, including fee estimation, token gassing (ERC-20 for fees), and sponsor transaction flows (ERC-4337) to abstract complexity from end-users.
Token & NFT Management
Build clear dashboards for managing AppChain-native assets (ERC-20, ERC-721, ERC-1155). Features include bulk actions, metadata display, and integration with your chain's native explorer.
Staking & Governance UI
Create user-friendly interfaces for native token staking, delegation, and on-chain governance participation specific to your AppChain's consensus and DAO mechanics.
Audit-Ready Component Library
Deliver a reusable, branded React component library built with TypeScript and Tailwind. Each component follows security best practices and is documented for your team's long-term maintenance.
Business Outcomes: Why a Custom Wallet Interface Matters
A purpose-built wallet interface is a strategic asset. It directly impacts user retention, security posture, and operational efficiency. Here’s how our design delivers measurable results.
Accelerated User Onboarding
We implement streamlined flows for seed phrase backup, social logins (via MPC), and fiat on-ramps. This reduces drop-off by up to 70% compared to generic wallet UIs, getting users to their first transaction faster.
Enhanced Security & Trust
Built-in transaction simulation, clear signing requests, and real-time risk alerts (e.g., for suspicious contracts) drastically reduce user error and phishing success rates. This builds user confidence and protects your platform's reputation.
Increased User Engagement & Retention
Custom features like in-wallet staking, NFT galleries, and gasless transaction sponsorship keep users within your ecosystem. A tailored experience leads to higher session duration and repeat usage.
Reduced Support Burden & Costs
An intuitive, self-explanatory interface with embedded educational tooltips and clear error messages deflates support ticket volume for common issues like failed transactions or lost keys.
Seamless Multi-Chain & dApp Integration
We design for interoperability from day one. Native support for EVM, Solana, and Cosmos SDK chains with WalletConnect v2 integration ensures your users can access the entire dApp landscape without friction.
Future-Proof Architecture
Our modular design, using React/TypeScript and Wallet Kit frameworks, allows for rapid integration of new tokens, protocols, and features (like account abstraction). This ensures your wallet evolves with the ecosystem.

Our 4-Phase Design & Development Process
A structured, milestone-driven approach to deliver secure, user-centric wallet interfaces on time and on budget. Each phase includes client reviews and approval gates.
Phase 1: Discovery & Strategy
We conduct a technical deep-dive into your AppChain's architecture, token standards, and target user flows. Deliverables include a comprehensive requirements document, user persona mapping, and a prioritized feature roadmap.
Client Value: Aligns the entire project on scope, budget, and technical feasibility from day one.
Phase 2: UX/UI Design & Prototyping
Our designers create high-fidelity, interactive prototypes for core wallet flows (onboarding, asset management, staking). We focus on Web3-specific UX challenges like transaction simulation, gas fee clarity, and seed phrase security.
Client Value: Validate the complete user experience and interface before a single line of code is written.
Phase 3: Frontend Development & Integration
Engineers build the production-ready React/Next.js interface, integrating with your AppChain's RPC nodes, indexers, and smart contracts using libraries like ethers.js or viem. We implement robust state management and wallet connection (MetaMask, WalletConnect).
Client Value: A fully functional, performant frontend that seamlessly interacts with your blockchain layer.
Phase 4: Security Audit & Launch
We conduct internal security reviews focusing on frontend vulnerabilities (e.g., dependency risks, injection attacks) and coordinate with your smart contract auditors. Final deployment to your infrastructure with comprehensive documentation and handover.
Client Value: Launch with confidence, backed by a security-focused review and complete operational ownership.
Frequently Asked Questions on AppChain Wallet Design
Get clear, specific answers to the most common questions CTOs and product leads ask when evaluating a custom wallet development partner.
We deliver a secure, production-ready MVP in 4-6 weeks for a standard wallet with core features (key management, token transfers, basic dApp connectivity). Complex integrations (multi-chain support, advanced transaction types, custom governance UI) extend the timeline to 8-12 weeks. We provide a detailed, phased project plan during discovery to ensure alignment.
