Curse of there being almost no one on the planet who can meaningfully audit this stuff. Good thing there's even less who know enough to be able to find and exploit it lol.

Wrote a PoC extension to ERC721 that allows for capital-efficient and risk-free lending of NFTs, effectively giving them a kind of "fixed income" capability.

No need to put up collateral to borrow an NFT, and no need to risk being rugged as a lender!

If anyone else is freehanding Yul in vim, I wrote a Yul syntax file with EVM-opcode specific highlighting which makes for easier casual skimming: https://t.co/rx0hbCCjeK

autoindent works okay even without a specific indent file

After hours of racking my brain on this, I finally figured out how to replace the tx.origin==msg.sender check after EIP3074:

After EIP150, all calls can at max sent 63/64 of the current total gas allowance. This can be used to recover this check.

@nicksdjohnson @edder5000 @techbubble Initially, Solidity was supposed to resemble js to make it look like web developer can easily learn it. We dropped that rather quickly, though, because the two languages are very different.

.@zklabs has announced Community Audits, an initiative to audit projects that have not held an initial coin offering and don't plan to. Confirmed auditors are @matthewdif, @nicksdjohnson, and @DeanEigenmann. https://t.co/CvrusT6MV7

[Austin Griffith @austingriffith]

Excited to announce @DeanEigenmann completed the audit of the smart contract for https://t.co/low7x9Kybp and https://t.co/O8uwXt2uOg as part of the ZK Labs Community Audits! You can now safely run trustless subscriptions and fund trustless grants on the Ethereum mainnet!!! 🚢💰⏰

[Bank Frick @BankFrick]

A highly interesting read by @ZKLabs' @MatthewDiF about #blockchain technology as a public good and the impact of a global standard protocol
on its network effects to prove #digital events. https://t.co/C83e7g7HF2

[ZK Labs @zklabs]

Planning to be in Berlin for any of the gazillion events happening from next week? @awasunyin and @DeanEigenmann from ZK Labs will be at the @zeroknowledgefm 's ZK Summit ZKx02, come fetch us if you want to discuss about @ethereum smart contracts and security!

[ZK Labs @zklabs]

@zeroknowledgefm hosted @matthewdif in this deep conversation on #blockchainsecurity

"[...] to become good at security, keep dwelling into blackboxes that people accept as blackboxes, be it a blockchain, smart contracts or whatever needs to be analysed"

Thank you @AragonProject Nest
for approving our proposal on building a private and scalable voting system on @ethereum
compatible with the @AragonOneTeam
Protocol!

Dev progress updates on Ethereum Ring Signatures coming soon!

Our @DexyProject internal audits are so intense we found a bug in solidity itself: https://t.co/EoC4nTIWJa
