Iβve joined the ZRC20 Fairlaunch Airdrop β‘οΈ
ZRC20 is the native on-chain token standard for @Zcash , built by the @BitX2100 team.
A new era of tokens on Zcash starts here. π¦
Iβm in. Are you? nitter.cf/bitx2100/status/210109β¦
ZRC20 Explained
The first native on-chain token standard built for Zcash.
Learn how ZRC20 works and how it brings fungible tokens directly on-chain.

chip in, get a piece of dino and have a hand in bringing jurassic park over to solana.
don't blame a man for dreaming.

dino for grabs, only up from here
24 hours left to bring Deaton, the first ever tokenized dinosaur, to @Solana

actually crazy this is happening.
The European Parliament voted AGAINST Chat Control. 314 to 276.
And it passed anyway.
Let me tell you how: they needed 361 votes to say no. On the last day before vacation. Every empty seat counted as a yes.
They lost the vote. They won the law.
Thatβs not democracy. Thatβs a trick. #ChatControl
was a fun one. big thanks to the whole crew that made this. I've especially liked READMEs tieing each chapter to the official rust book. guess it's time to catch up on @rektoff_xyz web3 sec bootcamp.
prompt your agent to parse your git history for secrets while you take lunch, rotate them if he finds any. its that simple.
we are all concerned with the token economics favouring the blackhats - while a simple git scraper enabled a 1.7M hack today. Commit pushed to github in '24 btw. How do we recommend dApps to our friends and family with such things happening?
π¨Taiko drained for ~$1.7M. Root cause: a private key committed to a public GitHub repo.
enclave-key.pem, the RSA key used to sign all of Taiko's SGX enclaves, sat in the public taikoxyz/raiko repo. That key is the whole trust model.
The attacker derived MrSigner from the public key, signed their own malicious enclave with the leaked key, and registered as a trusted prover. The L1 contracts trust any enclave whose MrSigner matches. It matched.
From there: forged SGX attestations on fake L2 blocks, processMessage() sets the message to RETRIABLE, retryMessage() does zero proof verification, funds leave.
No key theft. No social engineering. No SGX exploit. Just a .pem in a public repo.
Good opportunity to recall that SGX is broken. But here, nobody even had to break it.
It's just yet another key management failure. The whole system was only ever as strong as the secrecy of one RSA key, and that secrecy depended on a human not running git add . on the wrong folder. AI greps every commit of every public repo at machine speed. Assume that is already happening.
The only real exit: a verifier that checks a succinct validity proof of the L2 state transition. It trusts no enclave, no MrSigner, no operator discipline. It checks the math. In that world this exact attack becomes cryptographically impossible rather than operationally unlikely, because there is no privileged key whose leak forges the entire system. There is just a proof.
Stay safe.
Forked x-ray skill by @0xFireFist / @ PashovAuditGrp and adjusted it for Anchor/Solana. It's a pre-audit Claude skill that will give you a detailed architectural overview of the program you are auditing. Any feedback and/or contributions are well appreciated. π«‘

AI is getting ridiculously good, and it's making your security really messy... Hackers are using AI to find live bugs that were missed before AI was used in security.
If you've been audited in 2026 (at least since Q2), I'm fairly certain that every audit firm has used AI to audit your code.
However, ALL live codebases audited manually (probably pre-2026) NEED to be rechecked and triaged using AI. This applies to closed-source contracts, too.
If AI is better than any human at finding vulns, and AI audits began only a couple of months ago, what percentage of your codebase was secure against human blackhats, but not against AI?
I don't care who did your audit. Reach out to them and get a recheck of EVERYTHING. AI is only getting better, and it's going to continue to find exploitable mistakes that humans made.
