What Lindy Labs does

Lindy Labs is a privately held Web3 technology firm headquartered in the Cayman Islands, operating concurrently as a boutique consulting practice and a product company. Founded in 2022 with 11–50 employees, the firm serves financial institutions, governments, consumer brands, security-conscious protocols, and traditional organizations seeking to adopt or assess decentralized technology. Its core service lines are formal verification, software security assurance, Web3 and metaverse strategy, tokenization and capital markets advisory, and security-focused education, with new business acquired through direct engagement via email and website contact forms.

The company's technical portfolio is built on three pillars: Opus, an on-chain autonomous cross-margin credit protocol for synthetic assets featuring adaptive non-linear risk controllers and MEV-resistant liquidations; Aegis, a formal verification framework that uses Cairo's Sierra intermediate representation to enable interactive theorem proving in Lean for Starknet contracts; and Solidity Properties, a symbolic test suite for Ethereum contracts that uses hevm with Z3 and CVC5 SMT solvers to formally verify ERC20, ERC721, and ERC1155 implementations. Supporting verified libraries such as WadRay (fixed-point arithmetic) and a RISC-V Sail-to-Lean exporter extend the firm's reach across the Cairo, Ethereum, and zkVM/zkEVM stacks. Aegis has been used to verify Starkware's own corelib and fractions implementation, anchoring the firm inside the Starknet ecosystem.

The business model centers on bespoke, long-cycle consulting engagements rather than published pricing or self-serve products. Open-source repositories, published technical articles on formal verification, and active GitHub presence function as top-of-funnel demand generation and credibility signaling for the consulting practice. Strategic relationships include a funded collaboration with the Ethereum Foundation under its verified zkEVMs program, alongside University of Cambridge and Galois Inc.; a Starkware technology/integration relationship; and GDPR/DPL-compliant operations. No external funding rounds, revenue figures, named customers, or ownership details are disclosed, which is itself a material data gap for outside investors.

Core offering

Lindy Labs is a Web3 consulting firm that partners with clients on long-term engagements across Digital Strategy, Security, Formal Verification, Performance Transformation, and Education. In parallel, it develops proprietary on-chain and developer-tooling products (Opus credit protocol, Aegis verification framework, Solidity Properties symbolic testing suite, WadRay library) that double as both standalone offerings and credibility anchors for the consulting practice.

Product overview

Lindy Labs operates as both a product company and consulting firm. Their core product portfolio includes Opus (autonomous cross-margin credit protocol), Aegis (formal verification tool for Cairo contracts), and Solidity Properties (symbolic test suite for Ethereum). They provide consulting services in Security (software assurance, formal verification, security education), Web3 and Metaverse strategy, Tokenization and Capital Markets, and have contributed verified libraries like WadRay for fixed-point arithmetic.
