We architect and deploy custom smart contracts on EVM and Solana chains, from ERC-20/721 tokens to complex DeFi protocols. Our development process is built on security-first principles using OpenZeppelin libraries and comprehensive audit trails.
Account Abstraction Mobile Wallet SDK
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
- From MVP to Mainnet: Go from concept to a 2-week MVP or a fully audited mainnet deployment.
- Full-Stack Integration: We ensure seamless interaction with your front-end via
ethers.js/web3.js. - Post-Deployment Support: Includes monitoring, upgradeability planning, and incident response.
We deliver contracts that are not just functional but are engineered for security, gas efficiency, and long-term maintainability.
Core SDK Capabilities We Deliver
Our Account Abstraction Mobile Wallet SDK provides the foundational building blocks for secure, scalable, and user-friendly Web3 applications. We deliver production-ready modules, not just prototypes.
ERC-4337 Bundler & Paymaster Integration
Seamless integration with ERC-4337 infrastructure for gas sponsorship, batch transactions, and session keys. We handle the complexity of bundler RPC endpoints and paymaster policies so you can focus on user experience.
Smart Account Factory & Management
Deploy and manage ERC-4337 compliant smart accounts (like Safe{Core}) with deterministic addresses. Includes social recovery modules, multi-signature setups, and permission management out-of-the-box.
Cross-Chain Transaction Orchestration
Enable users to interact with assets and dApps across Ethereum, Polygon, Arbitrum, and other EVM chains from a single interface. Our SDK abstracts away bridge and chain selection complexity.
Biometric & Secure Key Management
Leverage device-native secure enclaves (iOS Secure Enclave, Android Keystore) for private key storage. Implements passkeys and biometric authentication (Face ID, Touch ID) for a seamless yet secure login flow.
Real-Time Gas Estimation & Optimization
Dynamic gas fee estimation with multi-layer mempool analysis. Implements EIP-1559 support and automatic fee optimization to reduce user costs by up to 40% during network congestion.
Modular dApp Connector & Session Management
A lightweight, modular Web3 provider compatible with ethers.js and viem. Supports ERC-4337 UserOperation signing and secure session keys for transactionless dApp interactions.
Measurable Outcomes for Your Game
Our Account Abstraction Mobile Wallet SDK delivers concrete, trackable improvements for your game's user acquisition, retention, and revenue.
Boost Onboarding Conversion
Replace complex seed phrases with social logins or passkeys. We deliver a seamless first-time user experience that reduces drop-off by up to 70%.
Increase In-Game Purchases
Enable gasless transactions and sponsor user operations. Remove friction from micro-transactions to increase average revenue per user (ARPU).
Enhance User Retention
Implement session keys for uninterrupted gameplay and automated social recovery for lost access. Keep players engaged, not managing wallets.
Accelerate Time-to-Market
Integrate a production-ready, white-labeled SDK in weeks, not months. Our modular architecture plugs directly into your existing game engine.
Scale with Your Player Base
Our infrastructure handles spikes in concurrent users with sub-second latency. Pay-as-you-go pricing scales with your game's success.
Phased SDK Development & Integration
Our phased approach ensures transparent delivery, from initial integration to full-scale production deployment. Each tier includes all features from the previous level.

Our Development & Integration Process
A streamlined, security-first approach to integrate Account Abstraction into your mobile app. We deliver a production-ready SDK in weeks, not months.
Architecture & Strategy Session
We analyze your use case and define the optimal AA architecture (4337, Safe, or custom). Deliverables include a technical spec, gas cost analysis, and a phased integration roadmap.
SDK Integration & Customization
Seamless integration of our modular SDK with your mobile stack (React Native, Flutter, Native). We implement core AA features: social logins, gas sponsorship, batch transactions, and session keys.
Smart Contract Deployment
We deploy and configure the necessary smart account infrastructure. This includes Account Factory, Paymaster for gas abstraction, and custom logic for your specific business rules.
Security Audit & Penetration Testing
Comprehensive review of the integrated wallet flow and smart contracts. Includes static analysis, manual review, and simulated attack vectors to ensure user funds are secure.
Staging Deployment & Testing
Full deployment to a testnet/staging environment. We conduct end-to-end user flow testing, load testing for paymaster reliability, and provide a detailed QA report.
Production Launch & Monitoring
We manage the mainnet deployment and establish monitoring dashboards for key metrics: user onboarding success rate, paymaster gas usage, and transaction failure analysis.
Build vs. Buy: Custom SDK vs. Generic Solutions
Choosing the right foundation for your account abstraction mobile wallet impacts time-to-market, security, and long-term costs. Compare the trade-offs between building from scratch, using a generic SDK, and partnering with Chainscore Labs for a custom solution.

Frequently Asked Questions
Get answers to common technical and commercial questions about our SDK development and integration services.
A standard integration for a production-ready mobile wallet takes 4-6 weeks. This includes initial setup, core feature implementation (social login, gas sponsorship, batch transactions), and a security review. For a POC or MVP with a subset of features, delivery can be as fast as 2-3 weeks. We provide a detailed project plan during the discovery phase.
