Bug bounty track record
Our researchers find real bugs in real protocols
Our researchers attack live protocols every day and publish what they find. Recent examples from Thomas, our bug bounty researcher. All reports are public.
PillarDAO
Staking vaultTwo reentrancy flaws in the vault, the kind of bug that lets an attacker drain funds. Confirmed with a working attack in a controlled test.
- HighReentrancy in withdraw()
- HighCross function reentrancy in deposit()
Ostium
Perpetual trading platformTraders could be liquidated before their own stop loss triggers, because two parts of the platform disagreed on the limit. Proven with a simulation on the live chain.
- LowStop loss vs liquidation mismatch
Upside
Social prediction marketFour findings in a single review, two of them high severity. One lets an attacker skip fees entirely with a fake token.
- HighFees bypassed with a malicious token + reentrancy
- HighMissing URL input checks
- MediumInput checks breaking the whitelist
- LowRounding (precision loss)
End to end protection
An incredible approach
SpotBlock protects a project from start to finish. The best security data feeds our AI and our researchers. Contracts and wallets are watched day and night, so problems get caught early.

Our products
Everything you need to stay safe, in one place
SpotBlock keeps watch for you, answers the only question that matters when money moves — is this safe? — and plugs into your own tools.
Real-Time Monitoring
We watch your wallets, treasuries and contracts 24/7 on Ethereum. When something risky happens — a strange transfer, a change of owner, an attack pattern — you get a clear alert.
- Large or strange movements on watched wallets
- Risky approvals and drain patterns
- Changes to critical contracts: owners, upgrades, pauses
Threat Check API
One simple question your app can ask before money moves: is this address safe, or a known threat? The answer comes straight from our live database.
- One request, one clear answer: safe or threat
- Always up to date — same data as the Explorer
- No danger list to build or maintain yourself
And more tools, ready to use
Scam check
A quick check in our database. See what we already flagged on a contract or wallet, and why.

The Explorer
Check any address — in plain words
Blockchains are open books: every wallet and contract is public. But reading raw blockchain data is a job for specialists. The Explorer turns it into a simple answer.
- Is this address flagged as dangerous?
- What does this contract actually do?
- Who created it, and when?
Free, no account needed — and it runs on the same live data as our monitoring.
Audit
Smart contract audits, by people who break things for a living
The researchers behind the public findings above audit your contracts the way an attacker would. SpotBlock AI and our research pipeline give them the best data to work with.
Scoping
We map what your project does and what matters most to protect.
Automated sweep
SpotBlock AI sweeps your code in minutes and flags the obvious weak spots.
Human review
A researcher hunts for attacks, line by line, like a thief would.
Proof of concept
Every finding is confirmed with a working attack before we report it.
Report & recheck
A clear report with fixes explained, then we verify your fixes.
