Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists for your protocol or dApp.
- Custom Logic: Build bespoke
ERC-20,ERC-721,ERC-1155, and novel token standards. - Protocols: DeFi primitives (AMMs, lending/borrowing), NFT marketplaces, DAO governance modules.
- Security: Adherence to OpenZeppelin standards, comprehensive unit/integration testing, and pre-audit review.
- Delivery: Full suite including source code, deployment scripts, and technical documentation.
We deliver contracts that are secure by design, enabling you to launch with confidence and scale without refactoring.

COMPREHENSIVE SECURITY ASSESSMENT
Our MEV-Focused Bridge Audit Deliverables
We deliver actionable, high-impact security reports designed to protect your bridge's value and users from sophisticated MEV attacks. Each audit is a deep technical review, not a checklist exercise.
01
In-Depth MEV Threat Analysis
A dedicated section mapping potential MEV vectors (sandwich attacks, front-running, arbitrage exploitation) specific to your bridge's architecture, with severity and exploitability ratings.

Risk Categorization
02
Smart Contract Security Report
Line-by-line code review of core bridge contracts (deposit, withdrawal, messaging) for vulnerabilities, gas inefficiencies, and logic flaws that could be exploited for MEV.

Technical Deep Dive
Frequently Asked Questions on Bridge MEV Security
Get clear, expert answers to the most common questions CTOs and technical founders have about securing their cross-chain bridges against MEV attacks.
A standard implementation for a custom bridge takes 4-6 weeks from kickoff to mainnet deployment. This includes threat modeling, smart contract development, integration testing, and a final security audit. For integrating our security modules into an existing bridge, timelines are typically 2-3 weeks. We provide a detailed project plan during the initial consultation.
