yAudit

yAudit (also known as electisec) is a specialized smart contract and zero-knowledge (ZK) security auditing firm launched in late 2021. The firm focuses exclusively on blockchain and DeFi security, combining resident expert auditors with a unique fellowship-based model that brings additional security researchers into each engagement.

With a track record of securing over $2.1 billion in total value locked (TVL) and identifying 500+ critical vulnerabilities across 58+ audits in 2024 alone, yAudit has established itself as a leading security partner for Ethereum-based protocols. The firm's client roster includes notable DeFi protocols such as Curve Finance, Yearn Finance, Euler, Centrifuge, Olympus DAO, Nouns DAO, Superfluid, and many others.

Core Services

yAudit offers three primary security services for Web3 protocols:

• Smart Contract Security Audits: Comprehensive code reviews of Solidity and EVM-compatible smart contracts, covering architecture analysis, logic vulnerabilities, and remediation guidance with severity classifications and proof-of-concept exploits.
• ZK Security Audits: Specialized auditing of zero-knowledge circuits, zkSNARKs, zkSTARKs, and cryptographic protocol implementations — an area the firm expanded into significantly in 2024 with support from an Ethereum Foundation grant.
• Boosted Audits: An innovative model that combines resident auditor expertise with 50+ additional security researchers (fellows) reviewing the codebase simultaneously, providing breadth and depth of coverage.
• Consulting & Due Diligence: Strategic security guidance on protocol architecture, algorithm correctness, threat modeling, and design-level risk assessment for blockchain projects at any stage.

Key Strengths

yAudit differentiates itself through its fellowship programs — intensive 4-8 week cohorts where top security talent audits real production codebases alongside residents. With 8 completed fellowships since 2021 and 147+ fellows graduated, this model creates a pipeline of elite security researchers and provides clients with boosted audit coverage unavailable elsewhere.

The firm has deep expertise in both traditional DeFi security (yield optimization, lending, AMMs, governance) and cutting-edge ZK cryptography (circuits, proof systems, zkEVM, cross-chain middleware).

Notable Clients

Curve Finance, Yearn Finance, Euler Finance, Centrifuge, Olympus DAO, Nouns DAO, Superfluid, Manifold Finance, Temple DAO, Inverse Finance, Rage Trade, Asymmetry Finance, vfat, Strike, and many others.
