SECURE FOUNDATION
Custom Smart Contract Development
Production-ready smart contracts built with enterprise-grade security and gas optimization.
We architect and deploy secure, auditable smart contracts that form the core logic of your application. Every contract is built on Solidity 0.8+ with OpenZeppelin standards, undergoes rigorous internal review, and is optimized for gas efficiency and upgradeability via proxies.
A secure, well-architected contract suite is non-negotiable. It's your product's backbone and your users' primary security guarantee.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with minting, vesting, and governance modules. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking contracts, and yield aggregators.
- Utility & Access: Multi-signature wallets, subscription models, and role-based access control (RBAC).
- Deliverables: Fully documented source code, deployment scripts, and a comprehensive security review report.

Frequently Asked Questions
Get clear answers on our process, timelines, and technical approach for designing and implementing your AA wallet economy.
Our engagement follows a structured 4-phase process: 1) Discovery & Strategy (1-2 weeks): We analyze your user base, tokenomics, and target chains to define the AA architecture. 2) Smart Contract & SDK Design (2-3 weeks): We architect and audit the core smart accounts, paymasters, and bundlers. 3) Integration & Development (3-5 weeks): We implement the wallet SDK, integrate with your dApp, and set up gas sponsorship logic. 4) Testing & Launch (1-2 weeks): We conduct security audits, simulate user flows, and deploy to mainnet. This process ensures a predictable path from concept to launch.
