CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From tokenomics to complex DeFi primitives, we translate your requirements into gas-efficient, upgradeable, and secure on-chain systems.
- Custom Logic: Tailored
SolidityorRustcontracts for DeFi, NFTs, DAOs, and enterprise applications. - Full Lifecycle: Development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring. - Security Foundation: Every contract undergoes internal review against common vulnerabilities before external audit.

Our Development & Integration Process
A structured, four-phase approach to deliver a production-ready, secure, and scalable Account Abstraction wallet-integrated badge system. We focus on clear milestones, transparent communication, and audited code to ensure your project launches on time and within spec.
01
Architecture & Smart Contract Design
We architect your badge system's core logic using ERC-1155 for gas-efficient batch operations and design custom Account Abstraction (ERC-4337) modules for seamless wallet integration. This phase defines gas optimization strategies and security patterns.

Secure Smart Contract Development
Our team writes, tests, and deploys your custom smart contracts using Solidity 0.8+ with OpenZeppelin libraries. Every contract undergoes rigorous unit and integration testing on a forked mainnet environment before deployment.

Audit, Deployment & Monitoring
Prior to mainnet launch, contracts undergo a third-party security audit. We handle deployment across chosen testnets and mainnet (Ethereum, Polygon, Arbitrum), followed by setup of monitoring dashboards for transaction success rates and gas usage.

Frequently Asked Questions
Common questions from CTOs and product leads about implementing wallet-integrated badge systems with Account Abstraction (ERC-4337).
From design to mainnet launch, a standard deployment takes 3-6 weeks. This includes 1 week for architecture & smart contract design, 2-3 weeks for development and internal QA, and 1-2 weeks for client testing and deployment. Complex integrations (e.g., multi-chain, custom relayer logic) can extend this to 8-10 weeks.
