When the chain is on fire, someone answers.
0xCERT is an independent, non-commercial CERT. We coordinate incident response, advisories, and stolen-fund recovery across smart contracts, bridges, wallets, and Web3 infrastructure — on every chain that matters.

How response works
From first message to public advisory.
A repeatable playbook adapted from forty years of CERT practice to a world where the ledger is the crime scene.
- T+001
You reach out
Form, email, or a peer CERT. Partial information is fine — speed beats completeness.
- T+60s02
On-call is paged
A human analyst acknowledges and assigns a case ID (CASE-YYYY-NNNN).
- T+24h03
Triage & containment
War room with your team, exchanges, bridges, and wallet vendors to stop the bleeding.

Public advisory
Post-mortem, IOCs, and remediation published — signed, numbered, and syndicated.
Mission
Nobody owns the incident. So we coordinate it.
Traditional CERTs were designed for IP networks, TLS certificates, and a small set of vendors. Blockchains have none of those assumptions. Code is the bank, the ledger is public, and the attacker keeps the funds the moment a transaction lands.
Protocols, bridges, wallets, validators, and exchanges all touch the blast radius of a single exploit, but none of them have the standing to coordinate the others. We do.
We are non-commercial, vendor-neutral, and chain-agnostic. We don't sell a product. We answer the phone, run the war room, publish the advisory, and feed the IOC list to everyone who needs it — for free.

Keplr Google/Apple-login wallets drained after Web3Auth security incident; social login paused
Unauthorized transactions hit some Keplr accounts created with Google or Apple login via Web3Auth. Keplr and Web3Auth paused social login; affected users should not send new funds to those accounts. Recovery-phrase and hardware wallets are not affected.
Malicious npm packages arc-contracts and evmos-contracts: hosts that installed them should be treated as compromised
The npm packages arc-contracts and evmos-contracts, whose names suggest smart-contract tooling, were flagged as malicious (MAL-2026-18726 / GHSA-qcjv-pgw5-h2f5, MAL-2026-18727 / GHSA-ch75-7hv2-w5hw) and replaced by npm with security holding packages. Remove them and rotate any keys on machines that installed them.
Gnosis Pay discloses customer data breach on legacy system behind Gnosis Pay-branded cards; phishing risk for cardholders
Gnosis Pay says attackers gained unauthorised access to the legacy system powering its Gnosis Pay-branded (B2C) cards on 3 November 2026, exposing certain customer information. Funds were not affected. Affected cardholders should expect targeted phishing and never share seed phrases, keys, PINs or card numbers.
