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.

go-ethereum v1.17.8 security release fixes p2p DoS issues and a STUN-response node crash
go-ethereum (Geth) v1.17.8 is a security-focused release fixing several denial-of-service risks in the eth/snap p2p handlers, JUMPDEST analysis caching, BAL account handling, and a crash triggered by a rogue STUN server. Most fixes concern post-Amsterdam behaviour. Node operators should upgrade to v1.17.8.
MakerDAO ETH-A Liquidation Keeper Bot exploit — $538k lost on Ethereum
MakerDAO ETH-A Liquidation Keeper Bot lost an estimated $538k on Ethereum (improper access control), according to the DeFiLlama hacks database. Users and integrators should review exposure and follow the project's official channels.
GoldPesa exploit — $115k lost on Base
GoldPesa lost an estimated $115k on Base (incorrect share accounting), according to the DeFiLlama hacks database. Users and integrators should review exposure and follow the project's official channels.
