Multi-Ecosystem Storage Bridge Security Audit | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our development process is built on audited security patterns and includes comprehensive testing to mitigate risk.

Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance logic.
DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking contracts, and yield aggregators.
Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and custom business logic on-chain.

We deliver fully documented, auditable code with a 99.9% uptime SLA for deployed contracts.

Our iterative development includes formal verification where applicable and integration with tools like Hardhat and Foundry. We ensure your contracts are future-proof and interoperable with the broader EVM ecosystem.

PROVEN FRAMEWORK

Our Security Assessment Methodology

Our systematic, multi-layered approach delivers actionable security insights, not just a checklist. We assess your bridge's resilience against real-world attack vectors to ensure asset safety and operational integrity.

Architecture & Design Review

We analyze your bridge's core architecture for single points of failure, trust assumptions, and upgrade mechanisms. This includes evaluating cross-chain message protocols, validator sets, and economic security models.

Protocols Reviewed

5-Layer

Threat Model

Smart Contract Audit

In-depth manual and automated review of all on-chain logic (Solidity, Rust, Vyper). We focus on reentrancy, access control, arithmetic errors, and logic flaws specific to cross-chain asset handling.

SLOC Analyzed

Per Audit

OWASP Top 10

Compliance Checked

Cryptographic Analysis

Verification of signature schemes, key management, and zero-knowledge proof implementations. We assess the robustness of your bridge's cryptographic primitives against known and novel attacks.

Multi-Party

Computation Review

FIPS 140-2

Standards Alignment

Economic & Incentive Modeling

Stress-testing the bridge's economic security under adversarial conditions, including slashing mechanisms, bonding curves, and liquidity provider incentives to identify extraction vectors.

Based Testing

Sybil Attack

Resistance Analysis

Operational Security Review

Assessment of off-chain infrastructure, including validator node security, governance processes, incident response plans, and key ceremony procedures for multi-sig setups.

BEYOND STANDARD SECURITY

Why a Specialized Bridge Audit is Critical

Standard smart contract audits miss the complex, cross-chain attack vectors unique to storage bridges. Our specialized assessment targets the specific risks that lead to catastrophic loss of funds and data.

Cross-Chain State Consistency

We rigorously test the synchronization of data states across all connected chains (Ethereum, Solana, Polygon, etc.) to prevent double-spends, data corruption, and replay attacks that generic audits overlook.

Relayer & Oracle Security

Deep analysis of your off-chain infrastructure—relayers, oracles, and signers—for centralization risks, signature validation flaws, and liveness failures that are the #1 cause of bridge exploits.

Economic & Incentive Modeling

Stress-test your bridge's economic security, including validator/staker incentives, slashing conditions, and withdrawal delay mechanics to ensure resilience against economic attacks.
