COMPREHENSIVE SECURITY REVIEW
Our NFT Aggregator Audit Focus Areas
We conduct deep technical audits across all critical components of your NFT aggregator, from core smart contracts to economic incentives. Our structured approach identifies vulnerabilities before they impact your users or treasury.
01
Core Aggregator Logic
In-depth analysis of order routing, fee calculation, and settlement mechanisms. We verify the integrity of cross-marketplace aggregation to prevent slippage manipulation and failed transactions.

Line Coverage
O(1) Checks
Slippage Validation
02
Token & Approval Security
Rigorous review of ERC-20, ERC-721, and ERC-1155 token handling. We ensure secure approval patterns to prevent phishing and drainer attacks, a common vector for aggregator exploits.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment to mainnet.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and cross-chain asset bridges.
- Full Lifecycle Support: From initial design and
Hardhat/Foundrytesting to deployment and on-chain verification.
We deliver auditable, gas-optimized code that reduces execution costs by up to 40% and accelerates your time-to-market to under 4 weeks for an MVP.

NFT Aggregator Audit FAQs
Common questions from CTOs and technical founders about our NFT aggregator audit process, timeline, and security methodology.
We employ a four-phase audit methodology: 1) Architecture Review to assess protocol design and economic incentives. 2) Automated Analysis using Slither, MythX, and custom fuzzers. 3) Manual Code Review by two senior auditors focusing on aggregator-specific risks like order routing logic, fee accrual, and slippage controls. 4) Final Report & Remediation Support with prioritized findings and proof-of-concept exploits. Our process is based on OpenZeppelin's security standards and has secured over $2B+ in NFT trading volume.
