We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, NFTs, and DAOs. Our team specializes in Solidity, Rust (Solana), and Vyper, implementing OpenZeppelin standards and formal verification patterns from day one.
Account Abstraction for Hotspot Onboarding
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your decentralized applications.
- Custom Logic: Build bespoke DeFi primitives, governance systems, or asset tokenization.
- Security-First: Every contract undergoes internal review and is structured for seamless third-party audits.
- Gas Optimization: We write efficient code to minimize transaction costs for your users.
- Full Deployment: We handle testing, verification on Etherscan/Solscan, and mainnet deployment.
Deliver a secure, scalable smart contract foundation in 2-4 weeks, reducing your technical risk and accelerating your roadmap.
Core Technical Capabilities We Deliver
We architect and deploy production-ready Account Abstraction (ERC-4337) infrastructure, enabling seamless, gasless onboarding for your IoT and DePIN networks.
Smart Account Factory & Bundler
Deploy a custom, audited ERC-4337 EntryPoint and Smart Account factory. We integrate a high-performance bundler to batch user operations, reducing gas costs by up to 40% for mass onboarding events.
Gas Abstraction & Sponsorship
Implement flexible paymaster strategies—from full sponsorship to user-paid models. Our system handles gas fee estimation, sponsorship logic, and secure fund management, abstracting complexity from end-users.
Session Key Management
Engineer secure, time-bound session keys for automated device actions. We implement granular permission systems, enabling hotspots to perform specific functions (like data attestation) without full wallet access.
Cross-Chain User Operations
Build interoperability layers for AA operations across EVM chains. We enable your users to onboard and interact with hotspots on one chain while managing assets or identities on another, simplifying the multi-chain experience.
Security & Audit Integration
Deliver contracts built on OpenZeppelin libraries with formal verification where applicable. We facilitate audits with top firms and implement monitoring for anomalous paymaster spending or key usage.
Device Onboarding SDK
Provide a lightweight SDK for your firmware, enabling hotspots to generate AA wallets, request session keys, and sign user ops. Includes modules for secure key storage on constrained devices.
Business Outcomes for Your DePIN Project
Our Account Abstraction infrastructure for Hotspot Onboarding translates directly into measurable business results. We deliver the technical foundation that drives user growth, operational efficiency, and network security.
Frictionless User Onboarding
Replace complex seed phrases and gas payments with one-click, social logins and sponsor transactions. Increase user activation rates by 60%+ by removing the primary barrier to entry for non-crypto-native participants.
Reduced Operational Overhead
Automate gas fee sponsorship and batch transactions for device registration. Cut operational costs by up to 40% by eliminating manual wallet management and streamlining bulk onboarding processes for network operators.
Enhanced Network Security & Compliance
Implement session keys and transaction policies to limit device permissions. Mitigate key management risks and ensure compliant, auditable interactions with your DePIN hardware, protecting your network's integrity.
Accelerated Time-to-Market
Leverage our pre-audited, modular AA smart account infrastructure. Deploy a production-ready onboarding flow in under 3 weeks, not months, allowing you to capture market share and begin scaling your physical network faster.
Scalable Network Growth
Architected for high-throughput device registration and data attestation. Support thousands of concurrent onboarding events with sub-second finality, ensuring your network can scale without technical bottlenecks.
Actionable Network Analytics
Gain real-time insights into onboarding funnel drop-off, gas sponsorship costs, and user cohort behavior. Make data-driven decisions to optimize incentives and improve hardware deployment strategies.

Our Development & Integration Process
A structured, four-phase approach to deliver secure, production-ready Account Abstraction infrastructure for your hotspot onboarding, from concept to launch.
Architecture & Smart Contract Design
We design and deploy custom Account Factory and Paymaster contracts tailored to your specific tokenomics and user flow. Built with Solidity 0.8+ and OpenZeppelin security patterns for gas efficiency and audit readiness.
Bundler & Paymaster Integration
Seamless integration of a high-performance ERC-4337 Bundler and a custom Paymaster to sponsor user onboarding transactions. We ensure sub-second user operation processing and configurable gas sponsorship policies.
Frontend SDK & Wallet Connection
We provide a lightweight, type-safe SDK (React/TypeScript) for your dApp, handling smart account creation, user operation signing, and seamless wallet connection via popular providers like Privy or Dynamic.
Testing, Auditing & Deployment
Comprehensive unit and integration testing, followed by a security review from our in-house auditors. We manage the deployment to your chosen network (Ethereum, Polygon, Base) and provide ongoing monitoring dashboards.
Smart Contract Development
Secure, audited smart contracts built for production by blockchain-native engineers.
We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built for security and speed, delivering a production-ready MVP in 2-4 weeks.
We don't just write code; we engineer resilient financial primitives that handle real value.
- Security-First Development: Code built with
Solidity 0.8+andOpenZeppelinlibraries, following formal verification patterns. - Full Audit Readiness: Contracts are developed with internal review and structured for seamless third-party audits from firms like
CertiKorQuantstamp. - Gas Optimization: Every line is optimized for efficiency, reducing user transaction costs by up to 40% versus unoptimized benchmarks.
Frequently Asked Questions
Get clear answers on how we deliver secure, scalable, and user-friendly onboarding solutions using Account Abstraction.
Standard implementations take 2-4 weeks from kickoff to production deployment. This includes smart contract development, integration with your frontend, and security review. Complex multi-chain deployments or custom paymaster logic may extend this to 6-8 weeks. We provide a detailed project plan during the initial consultation.
