What solidity labs does
Solidity Labs is a San Francisco-based smart contract engineering firm founded by Elliot Friedman in 2019. The company develops and secures on-chain systems for two primary customer segments: DeFi protocols (lending, stablecoins, DEXs, multi-chain governance, custody products) and financial institutions (banks, fintechs, asset managers) seeking to move operations on-chain without building internal blockchain expertise. Its flagship engagement record spans a decentralized stablecoin protocol ($1.2B TVL), Moonwell's cross-chain lending system across Ethereum/Base/Optimism ($375M TVL), a cross-chain DEX bridge between Ethereum and Cosmos ($206M TVL), and Volt Protocol ($25M TVL), with a stated aggregate of $2.1B+ in TVL secured across all engagements and zero recorded losses or hacks.
The core technology stack targets the Ethereum Virtual Machine and EVM-compatible chains (Ethereum, Base, Optimism, Arbitrum, Moonbeam, Cosmos bridge). The firm delivers full software development lifecycle support covering architecture and system design, production Solidity engineering, deployment and on-chain operations, testing, and formal verification (notably using the Certora Prover). Its principal open-source product is the Forge Proposal Simulator (FPS), a Foundry-based framework that simulates governance proposals end-to-end (deployment scripts, calldata generation, on-fork execution, post-proposal state validation) and natively supports OpenZeppelin Timelock, Gnosis Safe, Compound Governor Bravo, and OpenZeppelin Governor. Additional open-source contributions include the SEAL Security Frameworks (with the Security Alliance), the Zelt rate-limiting library, a Code Review Checklist, and a Secure Development Workshop. The firm also founded Kleidi, a timelock-based smart wallet built on Gnosis Safe.
Commercially, Solidity Labs operates as a boutique professional services consultancy with two revenue streams: (1) custom smart contract engineering engagements delivered via direct enterprise sales to protocols and financial institutions, with quote-based pricing and multi-year contract cadences, and (2) ongoing advisory retainers covering PR reviews of critical components, incident response, and continuous code review. Go-to-market combines direct institutional outreach with a community-led motion: open-source tooling (FPS, SEAL, Zelt, educational content) drives top-of-funnel discovery and credibility, culminating in inbound enterprise conversion. The firm maintains a global operating footprint spanning North America, Europe, and Asia-Pacific, is privately held with founder ownership, and has disclosed no institutional funding rounds.

solidity labs competitors and assessment
Company assessmentDirect peers
- Trail of Bits: Established smart-contract and blockchain security firm offering audits, formal verification, and engineering services. Directly competes with Solidity Labs for institutional DeFi and TradFi-on-chain engagements with overlapping service lines.
- OpenZeppelin: Provides smart-contract security audits, developer tooling (OpenZeppelin Contracts, Defender), and advisory services. Competes head-to-head on audit, retainer, and open-source governance tooling that Solidity Labs' FPS targets.
- Spearbit: Curated network of independent smart-contract security researchers offering audits and formal verification. Competes for the same institutional and protocol audit and engineering engagements as Solidity Labs.
- ChainSecurity: Smart-contract auditing firm spun out of the ICE Center at ETH Zurich, focused on DeFi protocol and institutional client audits. Overlaps directly with Solidity Labs' core DeFi and lending-protocol audit and engineering work.
- Zellic: Smart-contract security firm founded by top competitive auditors, serving DeFi protocols and institutions. Directly comparable audit and security-research service offering for similar institutional client profiles.
- Runtime Verification: Formal verification and smart-contract security firm with deep academic roots. Competes for the same formal-verification-heavy engagements where Solidity Labs applies Certora-based methods.
- Code4rena: Audit-competition platform for smart contracts, attracting protocols and reviewers including top Solidity engineers. Competes for protocol-level security review work that Solidity Labs also delivers through retainer and audit engagements.
- Certora: Provider of formal verification tooling (Certora Prover) and audit services for smart contracts. Notable as both a tooling partner Solidity Labs leverages and a competitor in formal-verification-led engagements.
- Sigma Prime: Blockchain security and infrastructure firm offering smart-contract audits and lighthouse/eth2 client work. Overlaps with Solidity Labs' smart-contract audit and engineering service offering for institutional and DeFi clients.
Emerging players
- Cantina: Audit platform and security services marketplace for smart contracts, including competitions and curated reviewer pools. A newer competitor pursuing the same DeFi and institutional audit pipeline with a platform-led model.
