I observed a round transition in the DAI/USD @chainlink price feed and compared FluxAggregator expectations with OCR behaviour through latestRoundData, including the timing between round start and when new data becomes available. https://t.co/lFhl7MF7vU

[Valya @ValZaitseva]

Here is my research on price feed phase boundaries, uncovering an unexpected phase overlap - a subtle but important nuance of Chainlink’s internal mechanics. Findings are compiled into a table and diagram below. My article lives at https://t.co/AWjzshXObx.

I took a deep dive into how Chainlink’s roundId works under the hood. My technical breakdown of its bit-level structure, phase mechanics, and an implementation nuance affecting historical price retrieval logic is at https://t.co/FJQRGQ9PAI
I'll be grateful for feedback

Performed an invariants-first security audit of Aave v3 borrow(). Instead of line-by-line review, I mapped protocol invariants to enforcement points in code, treating missing enforcement as red flags to build the failure surface and threat model. Report at https://t.co/2AZddSBk79

@pashov Oh, no, it's incredible! You are writing about $900k per month and a proprietary AI security solution, but I, as a human being, posted an article about intensive consol logging... 🤣

I just published my new article: Protocol Workflow Analysis via Intensive Console Logging: Invariant Discovery Without Code Review https://t.co/JXoMy75op3 via @LinkedIn
Any feedback is welcome!

I am on my way to audit Vyper smart contracts - the introduction course to Vyper development is over. Thanks to @CyfrinUpdraft and personally to @PatrickAlphaC and @ProgrammerSmart !
An intermediate course is ahead!

This monster is my attempt to build a diagram for aave-v4 'supply' feature - I'm mastering Owen Thurm's @GuardianAudits GTDA framework for manual security research. Diagramming helps a lot during a second pass of a contract reading session.

👋I just started an AI First Flight challenge, and it turned out that "Algo Ssstablecoinsss" contracts are written in Vyper, so I started a course on Cyfrin Updraft and just deployed a Smart Contract using @vyperlang!
Thanks @PatrickAlphaC, @zksyncdevs, and @cyfrinupdraft!

I'm claiming testnet tokens for @zksync v2, an EVM-compatible ZK Rollup!
