CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for your Web3 application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your dApp. Our development process is built on Solana, EVM, and Move-based chains using OpenZeppelin standards and rigorous security-first practices.

  • From Concept to Mainnet: Full-cycle development from technical design to deployment and monitoring.
  • Security as Standard: Every contract undergoes internal audits and formal verification before deployment.
  • Gas Optimization: We write efficient code to minimize transaction costs and maximize user savings.

We don't just write code; we deliver audit-ready, battle-tested contracts that protect your users and your reputation.

Our deliverables include comprehensive technical documentation, deployment scripts, and a post-launch support plan to ensure your protocol's long-term stability and success.

PROVEN PROCESS

Our Security Review Methodology

Our structured, multi-layered approach ensures your wallet infrastructure meets the highest security standards, protecting user assets and your company's reputation.

01

Architecture & Design Review

We analyze your wallet's core architecture, key management strategy, and transaction flow for inherent vulnerabilities before a single line of code is audited.

50+
Design Patterns Reviewed
OWASP Top 10
Compliance Check
02

Smart Contract & SDK Audit

Manual and automated review of your smart contracts (Solidity, Rust) and SDKs for logic flaws, reentrancy, and gas optimization, following industry standards.

Why a Professional Security Review is Critical

Self-audits and basic testing are insufficient for securing user assets. A professional review by seasoned experts identifies critical vulnerabilities that automated tools miss, protecting your reputation and preventing catastrophic financial loss.

01

Prevent Catastrophic Financial Loss

Identify critical vulnerabilities like reentrancy, access control flaws, and logic errors before they are exploited, protecting millions in user funds and avoiding irreversible damage to your treasury.

CORE INFRASTRUCTURE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy the foundational logic for your protocol. Our team delivers audit-ready contracts for DeFi, NFTs, and DAOs, ensuring security and gas efficiency from day one.

Build on a secure foundation with contracts designed for real-world use.

  • Custom Development: ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • DeFi & DEX: Automated Market Makers (AMMs), lending/borrowing pools, yield strategies.
  • Security-First: Adherence to OpenZeppelin patterns and comprehensive unit testing.
  • Gas Optimization: Code reviewed for maximum efficiency to reduce user transaction costs.

We manage the full lifecycle: from initial architecture and development through to deployment, verification on Etherscan, and post-launch monitoring. Get a production-ready MVP in 2-4 weeks.

Why a hybrid approach delivers superior security

Manual Expert Review vs. Automated Scanners

Automated tools are essential for catching common vulnerabilities, but they miss complex logic flaws and business logic exploits. Our service combines both for comprehensive coverage.

Frequently Asked Questions

Get clear answers on our security review process, methodology, and deliverables for wallet infrastructure.

We employ a hybrid methodology combining manual expert review with automated analysis. Our process includes: 1) Architecture Review of key management, transaction flow, and integration patterns. 2) Code Review of core cryptographic operations, RPC handling, and state management. 3) Dynamic Testing against a live testnet to simulate attacks like transaction malleability or gas griefing. 4) Dependency Audit of all third-party libraries for known vulnerabilities. We follow standards from OWASP, NIST, and our internal checklist derived from 50+ wallet security engagements.
