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.

Solidity compiler bug SOL-2026-7: Yul Optimizer Knowledge Base Stale Bookkeeping
The Yul optimizer could consider two memory or storage locations distinct even though their addresses were computed from different values of the same reassigned variable and coincided at runtime. This could lead to loads being replaced with outdated values and to needed stores being removed. Affects 0.8.19 ≤ solc < 0.8.38.
CVE-2026-93885: The Cryptocurrency Donation Box – Bitcoin & Crypto Donations plugin for WordPres
The Cryptocurrency Donation Box – Bitcoin & Crypto Donations plugin for WordPress is vulnerable to Stored Cross-Site Scripting via data_object Parameter in all versions up to, and including, 2.2.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by unauthenticated attackers because the cdbbc_payment_verify AJAX action is registered under wp_ajax_nopriv_ and its only authentication gate — a nonce check — is by…
Autheo THEO unbacked Hyperlane warp-route mint on Base drains about $1.7M
An attacker minted 19M unbacked THEO on Base through Autheo's Hyperlane warp route, then swapped it for about 700.8 ETH (~$1.76M per PeckShield) and bridged the ETH to Ethereum. Autheo says not to buy, sell, or bridge THEO until it gives an all-clear.
