BUILT FOR SCALE AND SECURITY
Core Architectural Capabilities
Our architecture is engineered to meet the stringent demands of high-volume applications, providing the foundational security, flexibility, and performance your product requires.
04
Gas Optimization & Cost Engineering
We specialize in reducing operational costs through advanced techniques: storage packing, batch operations, and efficient calldata usage. Our implementations consistently achieve 20-40% lower gas consumption versus unaudited industry averages.

DELIVERABLES & METRICS
Business Outcomes You Can Measure
Our EVM Smart Contract Wallet Architecture delivers concrete, measurable results for your product's security, speed, and scalability.
01
Enhanced User Security & Control
Implement Account Abstraction (ERC-4337) with social recovery, multi-signature policies, and session keys. This reduces user friction while maintaining non-custodial security, directly lowering support tickets related to lost keys by over 70%.

PROVEN PROCESS
Our Secure Development Methodology
We build secure, scalable smart contract wallets using a battle-tested, multi-layered approach that prioritizes security, auditability, and maintainability from day one.
01
Architecture & Threat Modeling
We begin with a formal threat model, identifying attack vectors and designing modular, upgradeable architectures using patterns like Diamond Proxy (EIP-2535) to isolate risk and enable future-proofing.
EIP-2535
Standard
Pre-Audit
Phase
02
Secure Implementation
Development follows strict standards: Solidity 0.8+ with OpenZeppelin libraries, comprehensive unit/integration tests (>95% coverage), and gas optimization reviews to ensure efficiency and security.

03
Multi-Stage Audits
Every contract undergoes internal peer review, automated analysis (Slither, MythX), and a final external audit by a top-tier firm like Spearbit or Code4rena before mainnet deployment.

Frequently Asked Questions
Get clear answers on our process, security, and delivery for custom smart contract wallet development.
Our process follows a structured 4-phase approach: 1. Discovery & Scoping (1 week): We analyze your requirements, user flows, and target chains. 2. Architecture & Design (1-2 weeks): We design the modular wallet architecture, gas optimization strategy, and security model. 3. Development & Auditing (3-6 weeks): Our team builds the core contracts, integrates modules, and conducts internal audits. 4. Deployment & Support (1 week): We deploy to testnet/mainnet and provide a 90-day bug-fix support window. We provide weekly sprint demos and maintain a shared Jira board for full transparency.
