Reentrancy
A contract calls out to another before updating its own state, letting an attacker re-enter and drain a balance in a loop.
↳ Root cause of the original DAO hack
Web3 Security Auditing
Audit the contract before the chain does.
We audit the smart contracts, DeFi protocols, and decentralized apps that hold your users' funds, finding the flaws an attacker would look for first. You ship to mainnet with a clear, prioritized security report and the confidence that your code does exactly what it promises.

The threat landscape
Where Web3 money actually goes missing.
Oracle Manipulation
A protocol trusts a price feed that can be moved with a flash loan, turning a single transaction into a profitable distortion.
↳ Common in DeFi lending exploits
Access Control
A privileged function ships without the right guard, so anyone can mint, pause, upgrade, or withdraw what they shouldn't.
↳ Found in a large share of audits
Bridge Logic
Cross-chain message passing accepts forged proofs or trusts a compromised validator set, releasing assets that were never locked.
↳ Behind the biggest crypto thefts
Economic Design
Tokenomics, fees, and incentives interact in ways nobody modeled, letting value leak out faster than the protocol earns it.
↳ Slow drains, hard to spot late
What we audit
One review stands between your code and someone else's profit.
01
Smart Contract Audit
We read your smart contracts line by line and pair manual review with automated analysis to surface logic errors, reentrancy, and access-control gaps before they reach mainnet. You receive a prioritized findings report and a free re-audit, so you can deploy knowing the code does only what it should.
SolidityManual reviewRe-audit
02
DeFi Protocol Audit
We assess the moving parts of your protocol, including tokenomics, liquidity pools, oracles, and yield logic, to find the economic and technical flaws attackers exploit. You leave with a clear risk picture and concrete fixes, so users and liquidity providers can trust your protocol with real money.

03
Token & Tokenomics Review
We model your token's supply, fees, and incentive design alongside the contract that enforces them to expose mint bugs, hidden traps, and structures that quietly drain value. You walk away with a defensible tokenomics report you can share with exchanges, investors, and your community.

04
NFT & Marketplace Audit
We test your NFT contracts and marketplace logic for minting flaws, royalty bypasses, and metadata risks that can erase a collection's value overnight. You get a clear remediation plan that protects creators and buyers and keeps your launch from becoming a cautionary headline.

05
Bridge & Cross-Chain Audit
We examine the contracts, validators, and message passing that move assets between chains, the layer behind the largest hacks in crypto history. You receive a hardened design and a findings report, so cross-chain transfers settle safely instead of disappearing into an exploit.

06
dApp Penetration Testing
We attack your decentralized application the way a real adversary would, probing the front end, wallet integrations, APIs, and on-chain calls for weaknesses that chain together. You receive a ranked list of vulnerabilities with proof and fixes, so problems surface in a test rather than a breach.

07
Protocol Threat Modeling
Before any audit code is written, we map how your protocol could be attacked: who benefits, which assumptions break, and where value concentrates. You get a threat model that guides safer design decisions and points the rest of your security budget at the risks that actually matter.

08
Post-Deployment Monitoring
We watch your live contracts and on-chain activity around the clock for anomalies, suspicious transactions, and emerging exploit patterns. You get early warning and a response playbook, so you can act on a threat in minutes instead of finding out after the funds are already gone.

How an audit runs
A process built to find bugs, not just tick a box.
- 01
Scope & threat model
We agree on the contracts, assumptions, and trust boundaries in play, then map the most likely ways your protocol could be attacked.
- 02
Manual + automated review
Our researchers read the code by hand while automated tooling sweeps for known patterns, so nothing hides behind a green test suite.
- 03
Report & severity ranking
Every finding arrives with a severity rating, a clear explanation, and a recommended fix your developers can act on immediately.
- 04
Re-audit & sign-off
Once your team ships the fixes, we re-review the changes and confirm each issue is closed before you go live.
Why Hoplon
A report your developers can act on in the morning.
An audit is only worth what your team can do with it. We hand you findings written in plain English, ranked by severity, with a fix for every issue, not a raw scanner dump.
Automated tools are part of how we work, but the bugs that cost real money live in business logic, and those only surface when an experienced researcher reads the code with intent. We treat your protocol like an attacker would, then explain exactly what we found and how to close it, and we verify the fixes before you go live.
- 01
Researchers, not a scanner
Automated tools catch the obvious. The expensive bugs hide in business logic, and those only surface when an experienced human reads the code.
- 02
Plain-English findings
Your report explains each issue in language your whole team understands, not a wall of tool output you have to decode.
- 03
A free re-audit, every time
We verify your fixes at no extra cost, because an audit that ends before the patch is no protection at all.
- 04
Built for the deadline
Launches and listings move fast. We scope tightly and deliver on a schedule that fits your mainnet date, not ours.
Common questions
What founders actually ask on the first call.
A written report listing every finding with a severity rating, a clear explanation, and a recommended fix, plus a free re-audit once your team ships the changes. You can share the report with exchanges, investors, and your community.
Most engagements run 10–14 days from kickoff to delivered report, depending on the size and complexity of the codebase. We scope every project up front so you know the timeline before you sign anything.
Yes. We scope tightly and schedule the review against your launch window, and we will tell you honestly if a date leaves too little time to audit safely rather than rush it.
We audit Solidity-based contracts across EVM chains and layer-2 networks, along with bridges that connect them. If your stack uses a non-EVM chain, tell us in the consultation and we will confirm fit before quoting.
We flag critical issues to you immediately rather than waiting for the final report, so your team can start remediation right away. The full write-up and re-audit follow as planned.
Free · 30 minutes · No obligation
Find the flaw before someone else does.
Spend half an hour with a Hoplon researcher. We will walk through your contracts, your launch timeline, and the risks we most often see in protocols like yours. You leave with a clear sense of where you stand, whether or not we run the full audit.
