Your Colosseum build survived the hackathon.
Now see if it survives an audit.
@vaultlinesec is offering up to $4,000 in audit services per project to Solana teams getting ready to launch or scale.
Security is what lets builders and users trust Web3, so we're giving back to the ecosystem that's supported us.
We're offering 10 audit grants worth up to 4,000 USDC each to Solana projects from the Colosseum Hackathon, to help teams launch and scale securely.
📅 Apply by Oct 31
📣 Winners announced Nov 2

Bitget breach: ~$387.5M drained.
No private keys stolen.
The attack came through compromised third-party software.
Secure the entire system, not just the keys.

Another reminder that in Web3, the attack surface goes beyond the code.
From unshipped fixes to oracle manipulation and module vulnerabilities — every layer matters.
🔐 Build. Review. Test. Secure.
Not every crypto hack starts with a code bug.
Sometimes, the real weakness is in the economics, oracles, and governance.
Here’s what recent incidents reveal.
AI agents are starting to trust and act on behalf of other AI agents.
But when trust becomes automated, security becomes critical.

Smart contract audits were built for code.
But AI agents are changing the attack surface.
When an autonomous agent can access wallets, call contracts, use APIs, and make decisions, security can no longer stop at the smart contract.
The question is no longer just “Is the code secure?”
It’s also “Can the agent be trusted with what it can do?”

Some of the biggest exploits in Web3 history didn’t just come from bad code.
Cross-chain bridges have become one of the industry’s biggest attack surfaces—putting billions at risk.
We break down some of the most expensive cross-chain bridge hacks and what we can learn from them.

$130M + 5,200+ wallets. Zero smart contract bugs.
Coldcard's root key broke from a single firmware bug — not a hack, not user error.
Security isn't the sum of its parts. It's only as strong as its weakest link. 👇
🚨 July 2026 was another costly month for Web3 security.
Top incidents this month:
• Ostium — $23.75M
• BonkDAO — ~$20–21.2M (reported, still unverified)
• Bonzo Finance — ~$9.05M
• Verus Bridge — $7.54M
• Lazy Summer Protocol — ~$6.04M
That's over $67M lost in just a few weeks.
The attacks weren't all the same:
⚠️ Oracle compromise
⚠️ Governance abuse
⚠️ Bridge exploit
⚠️ Smart contract vulnerability
⚠️ DeFi protocol exploit
Every exploit tells a story—and every story leaves a lesson.
🚨 Ostium Oracle Exploit
