Overview

OtterSec (legal entity Otter Audits LLC) is a blockchain security audit firm that reviews smart contracts, protocols, wallets, bridges and Layer-1 infrastructure across multiple ecosystems. It is best known in the Solana ecosystem, where its team maintains the Anchor framework, the dominant smart-contract framework for Solana programs. Beyond Solana its practice covers reverse engineering, formal verification and fuzzing as well as conventional manual code review. As advertised on osec.io in July 2026, the firm has audited 120+ projects, secures $36.82B+ of onchain TVL, has patched over $1.00B of vulnerabilities, and reports that 66% of its findings are core-severity. Its published client list includes the Solana Foundation, Sui Foundation, Algorand, Circle, MetaMask, Phantom, Backpack, PancakeSwap, Jupiter, Pyth Network and Raydium. The firm does not publish headquarters, funding or founder details on its website. OtterSec built its reputation on Solana-native security work and stewardship of the Anchor framework, and has since broadened into Move-based chains (Sui, Aptos) and general infrastructure audits, with the Otter Audits LLC entity active as of 2026.
