Free Web3 Security Consultations

Finding a reliable Web3 security audit shouldn’t be this hard. Endless pitches, wildly different quotes, and audits that miss the mark.

That’s why I’m offering free Web3 security consultations. I’ll help you:

- Pick the right audit type (M Review, fuzzing, FV, PR, Front-end security)
- Choose solo auditor vs. firm
- Recommend auditors/firms specialized in your protocol type (Staking, Wallet, bridge, ZK, NFTs, etc.)
- Share average price ranges so you can budget smart
- Guide you on audit prep—docs, tests, static analysis

No catch. No upsell. No strings attached. Just clear, tailored advice to keep your project secure and get the most value for your cash.

. @Sempoxyz is building borderless finance for the MENA region.

Remittance fees in Egypt can average up to 12%. Sempo brings that to less than 1%.

As a Guardian operator on Miden, Sempo abstracts all the private infrastructure complexity, so users just move money, privately, on onchain rails they never have to see.

@thesubmitter_ I know the Sharia complaint board advisors there, and they are among the best in the world, but I still don't like the idea.

@thesubmitter_ Amazing mash'Allah

Solana Security is about to start paying its juniors. real money. this monday🔥

I built Solana Audit Arena to see who'd show up anyway

who opens the code on a friday night

who keeps grinding when the leaderboard gives them nothing but a number

three weeks. zero prizes. you showed me

now those people get paid

if you've been auditing for free, this is your shot
if you know someone who has, send them this

Solana Audit Arena stops being free, and starts being sponsored and fair.

@kacieahmed I know, I just vibe-coded the frontend fast because of the hackathon, I will fix it.
Send me the 10k check

You either take the risk or end up working for someone who did.

Worst case scenario: you learn.
Best case scenario: it changes your whole life and trajectory.

Playing it safe never built anything worth remembering.

Announcing the Solana Audit Arena ⚔️

A free, weekly security competition for Solana security researchers.

Every Monday I drop a new Anchor program, built using the safe-solana-builder tool and real-world DeFi implementation.

Why?
→ Junior researchers have no clear path to prove themselves
→ No practice ground with realistic Solana programs
→ AI is raising the floor; you need to be above it

@0xcastle_chain Best rust auditor out there.

[Nour elden @nour608]

@Al_Qa_qa @0kage_eth Best of the best.

[0xFrankCastle🦀 @0xcastle_chain]

Solana devs, this one's for you.

Install Safe Solana Builder (one file, 30 seconds) and every program you write in Claude comes out:

• Security-checked from line one
• Loaded with real audit knowledge
• Packaged with a checklist of every rule applied

No extra effort. No security knowledge required. The skill does it for you

And as new vulnerabilities are found in the wild, I update the references.

You install once. You stay protected.

Solana master.

I built the first Claude skill for writing safe @solana programs.

Loaded with my personal audit knowledge. Security-first from line one.

Here's what it does:

[0xFrankCastle🦀 @0xcastle_chain]

The best security outcome for a $15k–$50k budget isn't a small team audit. It's a solo auditor with serious AI tooling.

Most protocols at this budget tier can't afford Spearbit-level engagements, and honestly, for many of them, that price point wouldn't even make sense as an ROI decision. So what's the actual best alternative?

A highly experienced solo researcher + an AI agent trained on deep, niche-specific vulnerability patterns.

The traditional argument for team audits has always been breadth: different researchers, different mental models, different blind spots covered. But AI is quietly closing that gap. Feed an agent with real vulnerabilities across protocols, environments, and portfolios, and you get surprisingly broad coverage without the overhead.

What you still need a human for: understanding the protocol at a systems level, catching the subtle and critical logic flaws that require context, eliminating false positives, and knowing which threads are actually worth pulling.

The researcher guides the agent. The agent expands the researcher's reach. That's the model.

This is how I approach Solana audits — combining efficient AI tooling with a structured vulnerability knowledge base specific to the ecosystem. It's not a shortcut. It's a different architecture for how security work gets done.

If you're building in this budget range and want a quote, DM me.
