Hi @veda_labs! I submitted a report to your BBP 5 months ago Since then I've received shifting justifications for non-payment. I even offered a ZERO reward if you can publicly state no fix is needed If fixing your contracts matters, please support my work by paying your bounties!

The end of an era. Thanks for all the opportunities! 🫡
Replying to @code4rena

I've spent every day for the last 14 months building a language for scripting LLMs because I believe we need new primitives to defend against prompt injection. Here's why: x.com/sockdrawermoney/status…

I met the team behind Unblind yesterday and I love the product... When you are about to make a transaction, it sends you a telegram message in plain english that describes what will happen! We all know blind signing is a problem and this is a great step! link to MM snap:

Wrote a post for the OZ blog 🔍 If you’ve ever wondered how Ethereum Execution Clients validate & process blocks/txs, this is a good place to start. I also dig into newer concepts like System Contracts & EL→CL Requests that unlock powerful use cases ⚡

A critical vulnerability I found in code forked from @1inch could have drained ~650k COVE tokens from @cove_fi contracts. Here's how the attack worked and how it was responsibly disclosed 🧵
9 Jul 2025
On June 12, 2025, a critical reentrancy vulnerability was identified by @adrianromero @yAuditDAO @electisec in Cove’s liquidity mining program and promptly neutralized. No user funds were lost, and 652,565 non-transferable COVE tokens were secured as a precaution. The vulnerability was introduced in @1inch token-plugins@1.0.0, and was integrated by Cove. This variant was never deployed within @1inch infrastructure.
