Ethereum Smart Contract Audit Services

ResearchZero provides Ethereum smart contract audits, blockchain security reviews, protocol risk analysis, and infrastructure security for teams building on Ethereum. Ethereum is the primary settlement environment for DeFi, tokenized assets, stablecoins, staking, governance, and on-chain financial infrastructure.

Ethereum blockchain security review

Ethereum systems often concentrate high value in upgradeable contracts, privileged roles, vault accounting, oracle dependencies, governance paths, and integrations with established DeFi liquidity.

ResearchZero reviews the chain-specific execution model and the financial logic built on top of it. The goal is to identify exploitable code paths before production value, user assets, governance authority, or institutional operations depend on them.

Engagements can include pre-launch audits, targeted reviews of remediations, protocol architecture review, cross-chain integration assessment, and post-audit support for engineering teams preparing a production deployment.

Ethereum risks we review

  • Upgradeable proxy controls
  • Oracle and pricing assumptions
  • Vault accounting invariants
  • Governance execution risk
  • MEV and transaction ordering
Programming Environment

Ethereum smart contract languages and tooling

Ethereum uses EVM account-based execution, ABI-encoded contract calls, gas-bounded transactions, and mature Solidity/Vyper production tooling.

ResearchZero reviews both the source-level implementation and the execution environment around it: compiler behavior, deployment artifacts, transaction construction, permissions, upgrade paths, and the runtime assumptions that can change how production code behaves.

Audit Coverage

Security services for Ethereum teams

Focused review for financial protocols, infrastructure providers, fintech teams, custodians, asset issuers, and DeFi applications building in the Ethereum ecosystem.

Smart contract audits

Manual review of code paths that move assets, authorize operations, settle balances, mint or burn tokens, route messages, or modify protocol state.

Protocol risk review

Adversarial analysis of economic assumptions, liquidity dependencies, oracle design, governance authority, upgrade controls, and operational failure modes.

Infrastructure assessment

Security review for bridges, relayers, indexers, signing flows, custody integrations, monitoring systems, and deployment processes around Ethereum applications.

Ethereum FAQ

Security review questions for Ethereum

Does ResearchZero support Ethereum?

Yes. ResearchZero supports Ethereum security reviews for smart contracts, protocol logic, infrastructure, and institutional financial applications.

What code and systems can be reviewed?

We review Solidity, Vyper, and EVM bytecode, protocol architecture, privileged operations, deployment controls, integrations, custody flows, and chain-specific assumptions.

When should a Ethereum audit happen?

Schedule review before mainnet deployment, major upgrades, new asset support, bridge integrations, custody changes, or any release that changes how value moves through the system.
