The firm focuses on embedded, long-term security partnerships with L1/L2 blockchains and DeFi protocols, and has disclosed multiple high-severity vulnerabilities across Cosmos, Solana, Ethereum, and Circle infrastructure. No regulatory actions, fraud allegations, or client harm incidents have been identified in available sources.","sections":[{"content":"Asymmetric Research is a private blockchain security firm offering embedded security engineering, smart contract audits, incident response, infrastructure validation, and security research. The firm describes its mission as becoming 'the most trusted security firm on the planet' serving web3 founders with high-stakes security needs. According to its website, the company employs 45 or more team members distributed across North America, Europe, and Asia. No specific founding year is disclosed in public sources, though activity on its GitHub security-advisories repository began in early 2024. The firm does not appear in any standard rankings of top smart contract audit firms published in 2026, which may reflect its positioning as an embedded partner rather than a transactional auditor.","heading":"Company Overview","sources":[{"url":"https://www.asymmetric.re/company","name":"Asymmetric Research — Company page","type":"official","credibility":1},{"url":"https://www.asymmetric.re/","name":"Asymmetric Research — Homepage","type":"official","credibility":1}],"severity":"low"},{"content":"Jonathan Claudius is co-founder and CEO.

Key verified disclosures include:\n\n- Cosmos IBC Reentrancy Infinite Mint (April 2024, Critical): A reentrancy vulnerability during IBC timeout message handling that could have allowed an attacker to mint an unlimited quantity of IBC tokens on affected Cosmos chains. The flaw put at least $126 million at risk according to reporting by CoinTelegraph and CoinDesk. Asymmetric Research disclosed the issue through Cosmos HackerOne's bug bounty program. No funds were lost and no exploit occurred.\n\n- Polygon Heimdall Log Confusion (February 2024, High): A log confusion vulnerability allowing Heimdall to parse specially crafted events as critical consensus events, potentially enabling a takeover of the network's consensus layer.\n\n- Circle / Noble CCTP Mint Bug (August 2024, Critical): A flaw in Noble-CCTP's ReceiveMessage handler that accepted BurnMessages from unverified senders, enabling potential counterfeit USDC minting. The effective impact was capped by Noble's mint limit of approximately 35 million USDC. Disclosed privately to Circle via bug bounty; no user funds lost.\n\n- Evmos Distribution Precompile DoS (June 2024, High) and Evmos Precompile State Commit Infinite Mint (August 2024, Critical): Two separate vulnerabilities in the Evmos chain's precompile execution layer.\n\n- Ethereum Ghost in the Block (September 2024, Medium): Nuances in SSZ deserialization between Prysm and Lighthouse consensus clients with potential consensus integrity implications.\n\n- Helix MEV Relay Proposer Equivocation (December 2024, High): Lack of validation on proposer commitments to blob data enabling unbundling attacks.\n\n- Marginfi Flash Loan Vulnerability (September 2025, Critical): A new instruction in the Marginfi lending protocol broke flash loan repayment verification logic, putting more than $160 million in user deposits at risk. Discovered by Felix Wilhelm via Marginfi's bug bounty program. Patched before any exploit.\n\n- Solana ZK ElGamal Proof / Token-2022 (April–May 2025): Asymmetric Research reviewed and provided incident support for the patch addressing a critical flaw in the ZK ElGamal Proof program's Fiat-Shamir Transformation implementation, alongside Neodyme and OtterSec. The original report was made by a researcher known as LonelySloth. No funds were lost.\n\n- Across Protocol Event Spoofing (April 2026): A vulnerability in Across Protocol where an attacker could spoof deposit events and deceive relayers into filling unfunded orders.\n\n- Solana p-token Bug Before Mainnet (April 2026): Felix Wilhelm disclosed a critical vulnerability caught during optimization work before the feature reached mainnet deployment.\n\nThe firm also disclosed vulnerabilities in CometBFT's BLS12-381 key validation and signature generation in September 2024.\n\nAll public disclosures on record were made through responsible disclosure channels (bug bounty programs or direct coordination), and no known instances of exploits occurring against patched code have been found in available sources.","heading":"Notable Security Disclosures","sources":[{"url":"https://github.com/asymmetric-research/security-advisories","name":"GitHub: Asymmetric Research Security Advisories","type":"official","credibility":1},{"url":"https://www.coindesk.com/tech/2024/04/23/patched-cosmos-bug-couldve-put-150m-at-risk-says-firm-that-reported-it","name":"CoinDesk: Patched Cosmos Bug Could've Put $150M At Risk","type":"news_article","credibility":1},{"url":"https://cointelegraph.com/news/cosmos-patches-bug-ibc-protocol-saves-126m","name":"CoinTelegraph: Cosmos patches critical IBC protocol bug, saving $126M","type":"news_article","credibility":1},{"url":"https://cointelegraph.com/news/critical-bug-identified-remedied-circle-noble-cctp","name":"CoinTelegraph: Critical bug identified and remedied in Circle's Noble-CCTP","type":"news_article","credibility":1},{"url":"https://blockworks.co/news/marginfi-flash-loan-bug","name":"Blockworks: Asymmetric Research discloses Marginfi flash loan bug that risked $160M","type":"news_article","credibility":2},{"url":"https://solana.com/news/post-mortem-may-2-2025","name":"Solana Foundation: Post Mortem — ZK ElGamal Proof Program Bug (May 2, 2025)","type":"official","credibility":1},{"url":"https://blog.asymmetric.re/threat-contained-marginfi-flash-loan-vulnerability/","name":"Asymmetric Research blog: Threat Contained — marginfi Flash Loan Vulnerability","type":"official","credibility":1},{"url":"https://blog.asymmetric.re/cosmos-ibc-reentrancy-infinite-mint/","name":"Asymmetric Research blog: Cosmos IBC Reentrancy Infinite Mint","type":"official","credibility":1},{"url":"https://blog.asymmetric.re/circles-cctp-noble-mint-bug/","name":"Asymmetric Research blog: Circle's CCTP Noble Mint Bug","type":"official","credibility":1}],"severity":"low"},{"content":"Asymmetric Research operates primarily through embedded, long-term security partnerships rather than one-off audit engagements.

The patch was distributed privately beginning April 17, 2025, with a supermajority of stake adopting it by April 18, 2025. Asymmetric Research, Neodyme, and OtterSec conducted patch reviews as part of the coordinated response.\n\nThe private coordination of the patch drew criticism from some in the crypto community who argued it raised concerns about centralization and validator collusion within the Solana network. Critics focused on the closed-door process rather than any conduct attributed to Asymmetric Research specifically. Asymmetric Research's role in this incident was as one of three reviewing security firms; the firm did not organize the patch process. No finding of wrongdoing has been attributed to Asymmetric Research in connection with this event.","heading":"Solana Patch Process and Decentralization Concerns","sources":[{"url":"https://solana.com/news/post-mortem-may-2-2025","name":"Solana Foundation: Post Mortem — ZK ElGamal Proof Program Bug","type":"official","credibility":1},{"url":"https://yellow.com/news/solana-vulnerability-patched-quietly-raising-concerns-over-validator-collusion","name":"Yellow.com: Solana Vulnerability Patched Quietly, Raising Concerns Over Validator Collusion","type":"news_article","credibility":2},{"url":"https://www.coindesk.com/markets/2025/05/05/solana-quietly-fixes-bug-that-could-have-let-attackers-mint-and-steal-certain-tokens","name":"CoinDesk: Solana quietly fixes bug that could have let attackers mint and steal certain tokens","type":"news_article","credibility":1}],"severity":"low"},{"content":"No regulatory actions, enforcement proceedings, court filings, or legal complaints involving Asymmetric Research have been identified in available sources as of September 2026.
