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.
- T+disclosure04
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.

rotki before 1.44.2: unsalted SHA-256 premium sync key lets attackers brute-force encrypted cloud backups
rotki before 1.44.2 derives its premium cloud-backup key from a single unsalted SHA-256 of the user password, so anyone holding a backup blob can guess passwords offline and decrypt exchange API keys and wallet data. Upgrade to 1.44.2 and rotate exchange API keys.
Yapeswap on Ethereum drained of about $21.9k after zero-quorum governance vote handed attacker YapeFactory feeToSetter role
Yapeswap's WorkersUnion governance had zero quorum, letting an attacker with ~0.000055% of voting power take YapeFactory's feeToSetter role and divert YapePair deposits to fake vaults (~$21.9k lost). Avoid Yapeswap pools and revoke approvals.
Keystone hardware wallet web shop breach exposed customer names, contact details and shipping addresses
Keystone says an unauthorized party accessed its official website and obtained customers' names, contact details, shipping addresses and order details; recovery phrases, keys and payment data were not exposed. Expect targeted phishing posing as Keystone refunds or replacement devices.
