The results for the Virtuals Protocol audit by @code4rena are in. This time, I secured 3rd place with a solo issue found, my first ever solo finding. A year ago, I couldn't have imagined reaching this milestone. Discipline truly is the key.

As of today, BattleChain testnet is LIVE. The pre-mainnet, post-testnet blockchain, where whitehats legally attack your smart contracts before they reach production. Deploy. Get attacked. Ship stronger. Here's why we built it, what it is, and how you can get involved 🧵

Happy belated Christmas! Sorry for the missed messages, I was not well. What happened: - Got tonsil infection start of the month - Kept working with fever while taking pain meds & antibiotics like candy. - Friday night I wake up and I can't breathe. - Can't open my mouth, can't talk. Breathing through the nose works but laborious. - I try and figure out what on earth is happening. After a few minutes I notice nose breathing is taking more and more effort, I need to get to a hospital fast. - Can't talk so calling ambulance is not an option. Writing it out for my wife so she can call might work but that takes time. Do I have the time? I don't know. - Get in the car and drive to the nearest ER. - Arrive at hospital, nurse sees me and presses a button. 2 policemen come out and help me in a bed (no idea why policemen). - Get rolled to different rooms, machines, tests, bright lights, masks, darkness (things are a bit fuzzy). - Wake up in a bed. Throat hurts but I can breathe. Cool! - Doc comes by and explains a massive abscess had developed in my tonsil and spread the infection to the throat, blocking airflow. They cut it open and drained it. Minor procedure in essence but quite urgent. - Spend a week hooked on an IV antibiotics drip. - Exit conversation with doc. I ask her if I can start working next week. She gives me a death ray eye glare and a 20m speech on how I might as well reserve an ICU bed for the month if I'm going to be this stupid. - Rest of the month I'm just sleeping and trying to relax So yeah, small infections can become somewhat problematic it seems. I'll be back on regular updates & respond to messages from January onward.

@FitroIvan “holidays” is a deprecated term for web3 auditors. What are you talking about mate?

@Ynyesto @PashovAuditGrp Thank you very much, Antonio, for your kind words,I really appreciate them. I also want to thank you for trusting me to audit your protocol. You’re an excellent developer, and I’m sure you’ll go very far.

In the end, they were audited by @FitroIvan, who's now collaborating with @PashovAuditGrp and did a tremendous job. My point is, if you're not a big company or VC-backed, you need to go the extra mile to find talent before they have been "made" (Sopranos fan here 😝)

Really enjoyed reading this post, because it is almost exactly what I did with @BitChillApp (only we have no token, nor will, most likely).
Jeffrey Scholz@Jeyffre

Trying to get a job as a Solidity developer — if you don’t already have experience — is… tough. There’s a big chicken and egg problem of nobody will trust you with TVL if you haven’t managed TVL before. That’s why there’s all these job boards with hundreds of applicants for Solidity jobs, but companies say they have a hard time finding talent. So I’m going to share a hack to get TVL on your resume. First — if you want to be paid to build Solidity protocols, you need to prove you can do it. So build a *real* project and stop applying for jobs with an NFT lottery or Uniswap V2 arbitrage or AAVE liquidator bot as your top showcase. Build a real protocol that does something non-trivial. In fact, build a few of them so you build up muscle memory. Stop expecting people to train you on the job, it’s not going to happen. “I’ll learn how to build a protocol after someone pay’s me to learn how” is a loser’s attitude. Stop being so entitled and show you are passionate about what you want to get paid for. Second — You need funding. Build the protocol AND THEN get a grant from an ecosystem that wants you to build on their chain (honestly this is EASY as chains need to show builder activity, you just need to pick the right chain). Then, use that grant to 1) get private audits for very cheap 2) attract users to the protocol, which I get to next… Third — Use the grant to create an incentive program for people to use your protocol. You don’t need to do a fancy airdrop program (you’ll never beat Monad at it, so don’t bother). Mint your new token right away, and create an Uniswap V2 pool of “real money” (from the grant) and your token. You don’t want to give the grant money away directly because you’ll run out too fast. But when you have a market for the token, it has a certain value, as long as most people don’t sell… (that’s what a “staking program” is for). Don’t be greedy with the token. Your job is to get users, not to try to get rich quick. Fourth — Show that your protocol gets farmers good yield when combined with your incentive program. Mercenaries and degens will flock to your protocol like flies to honey. Boom. Now you have users and TVL on your resume. The mercenaries will eventually leave and you will eventually run out of the grant money and your project will fade into irrelevance. Or, maybe you’ll get lucky, build a cool community, raise a VC round, and go on to great things. Either way now you have experience running a real protocol with real users and TVL. The best part is, if you actually follow through on this, there’s no need to embellish your story about how you managed TVL. You showed you actually know how to run a protocol, and you’ll be part of the few. The rest is easy after that. Now for the hard part: actually doing it. This is the part where 99.9% of you go back to scrolling social media after bookmarking this post. But for the three of you who just began an epic journey to protocol engineer, best of luck! (If you have experience managing TVL or pull of the plan I just outlined, apply to @RareTalent_xyz and we’ll get your a job pretty quick and seamlessly).

@0xSlowbug Sometimes it’s necessary to do that, and if people truly love you, they’ll understand. Let’s see how it goes, but I’m sure you’ll be satisfied.

Yesterday was Halloween, but I stayed home all night auditing and working hard. Last year, I spent it with friends, but this year my mindset has changed drastically. I want to focus on learning and improving my auditing skills. There’s a time for growth in everyone’s life.🌱

@mentasuave01 @BazziBazzani I agree, relationships are incredibly important, but there are times when you need to focus on your goals and give them slightly less attention.

@FitroIvan @BazziBazzani Life doesn't wait. People are the most important thing you have in life, take care of them. Do not procrastinate and make a hard schedule that will boost your productivity without sacrificing people's relations. But I get it... Sometimes you need to push

@FitroIvan People are what matter in the end. I'd be super careful. It's hard to find true friends after a lambo. Much easier before.
