About OtterSec
OtterSec is a blockchain security audit firm specializing in the Solana ecosystem, offering smart contract and protocol reviews. Its core strength lies in deep expertise in Solana's unique runtime and tooling, enabling detection of subtle vulnerabilities often missed by generic auditors. The company addresses the market need for specialized, high-assurance security in high-speed DeFi and cross-chain protocols, helping teams prevent exploits and build user trust. In the past six months (March–September 2026), OtterSec has expanded its audit portfolio across multiple Solana-based DeFi and infrastructure projects, published technical research on common smart contract pitfalls, and maintained an active presence in security communities. No major negative incidents have been publicly reported during this period.
In H1 2026, OtterSec co-published the Web3 Security Report with OKX and SlowMist, highlighting a 50% YoY increase in attack frequency but a 60% drop in losses, with users becoming the primary target.
OtterSec also launched and open-sourced PoRv2, a ZK-based proof-of-reserves system built with plonky2 and partnered with Backpack. It generates proofs for 750K users in 8 minutes, keeps final proofs under 500KB, and includes an open verifier server. Future focus is on real-time proof of reserves, greater transparency, reducing reliance on external auditors, and strengthening user-side security.
OtterSec was founded by Robert Chen in 2022. Robert Chen studied computer science at Carnegie Mellon University and previously worked as a mobile vulnerability researcher before founding OtterSec.
