Institutional Cross-Chain Bridge Mobile App Security Audit

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy audited, gas-optimized smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our process ensures your core business logic is secure and future-proof from day one.

Custom Development: ERC-20, ERC-721, ERC-1155, DeFi primitives, DAO governance, and bespoke logic.
Security-First: Formal verification, comprehensive unit/integration testing, and audits aligned with OpenZeppelin standards.
Gas Optimization: Achieve up to 40% lower transaction costs through efficient bytecode and storage patterns.

Move from concept to mainnet in as little as 4 weeks with a battle-tested development lifecycle.

We provide full technical ownership and documentation, enabling your team to iterate confidently. Our contracts are built for real-world compliance, integrating upgradeability patterns and multi-sig controls for enterprise-grade operations.

IN-DEPTH ANALYSIS

Our Comprehensive Audit Scope

Our security audit for institutional cross-chain bridge mobile apps is a multi-layered assessment designed to protect your assets and reputation. We deliver actionable findings, not just a report.

Smart Contract & Bridge Logic

In-depth review of on-chain bridge contracts, cross-chain message protocols (LayerZero, Wormhole, Axelar), and asset custody mechanisms. We identify logic flaws, reentrancy risks, and economic attack vectors.

Mobile Application Security

Static and dynamic analysis of your iOS (Swift) and Android (Kotlin/Java) codebases. We test for insecure data storage, keychain/keystore misuse, root/jailbreak detection bypass, and insecure inter-process communication.

Cryptographic Implementation

Verification of all cryptographic operations: key generation, storage, transaction signing (ECDSA, EdDSA), and secure enclave/TEE usage. We ensure no private key material is exposed in memory or logs.

Network & API Security

Assessment of RPC endpoints, oracle integrations, and off-chain relayers. We test for MITM vulnerabilities, API endpoint hardening, rate limiting bypasses, and secure WebSocket connections for real-time updates.

Frontend & Wallet Integration

Security review of Web3 provider integrations (WalletConnect, MetaMask SDK), dApp browsers, and in-app browser security. We check for phishing vectors, transaction simulation flaws, and approval hijacking.

Operational & Configuration Review

Analysis of CI/CD pipelines, dependency management, and infrastructure-as-code for backend services. We ensure no secrets are hardcoded and audit trails are immutable for compliance (SOC 2, GDPR).

ENTERPRISE-GRADE SECURITY

Why Institutions Trust Our Audits

Our security audits are engineered for institutional clients who require zero-tolerance for risk, regulatory compliance, and verifiable proof of security for their cross-chain infrastructure.

Protocol-Agnostic Expertise

We audit bridges built on any major protocol (EVM, Solana, Cosmos, etc.) and cross-chain messaging layers (LayerZero, Axelar, Wormhole). Our deep knowledge of diverse architectures ensures comprehensive vulnerability detection.
