Know the second your smart contract is at risk.
Real-time monitoring for ownership changes, large fund movements, and suspicious activity — before they become headlines.
Trusted by teams behind AngelSwap, Ecobal.eu, and dozens of teams shipping on Ethereum, BSC, and Polygon.
Most exploits aren't detected — they're discovered.
By the time a rug-pull or exploit makes it to Twitter, the funds are already gone. Ownership transfers, paused contracts, and suspicious large transfers happen in seconds — not when someone happens to check Etherscan.
How Tripwire3 monitors your contract
- 1
Connect your contract
Paste your contract address and pick your chain — Ethereum, BSC, or Polygon. No code changes required.
- 2
Set your alert rules
Choose what matters: ownership transfers, large transfers, pause state, proxy upgrades.
- 3
Get notified instantly
Email, Telegram, or webhook — the moment something changes on-chain.
Built for the risks that actually matter.
Ownership & admin alerts
Know immediately if contract control changes hands — the single biggest rug-pull signal.
Large transfer detection
Catch suspicious fund movements in real time, with configurable thresholds per asset.
Pause / unpause monitoring
Track contract state changes the moment they happen, before users get stuck.
Proxy upgrade alerts
Get notified before an upgrade silently changes your contract's logic.
Multi-chain support
Ethereum, BSC, Polygon — one dashboard, every chain, no extra setup.
AI-scored events
Risk-scored events with GPT-generated summaries so you know what to actually look at.
Run a full security audit on any contract in 90 seconds.
Slither static analysis with contract-type-aware ruleset weighting — reentrancy, access-control gaps, centralization risks, oracle manipulation, flash-loan exposure — summarized in plain English with a 0-100 risk score you can act on.
Verified source only
We pull the contract source straight from the block explorer. Unverified contracts are flagged immediately — no false sense of safety.
Contract-type-aware checks
ERC-20, ERC-721, proxy, DeFi, and DAO contracts each get a tailored checklist. The same finding is weighted differently depending on what you're shipping.
Plain-English AI summary
Every scan returns an AI-generated summary of the findings, a 0-100 risk score, and a severity breakdown — no Slither-fluency required.
Reentrancy & access control
Catches reentrancy, unchecked external calls, unprotected selfdestruct/delegatecall, missing onlyOwner/onlyRole modifiers, and access-control gaps.
Centralization & rug patterns
Detects single-owner mint authority, upgradeable proxy patterns, hidden owner functions, pausable transfers, and known rug-pull indicators.
DeFi-specific analysis
For DeFi contracts: oracle manipulation risk, flash-loan exposure, share-inflation patterns, reward calc edge cases, and reentrancy on token hooks.
Contract has privileged mint authority that can be transferred without timelock. Two reentrancy patterns detected on the withdraw path.
- CRITICALReentrancy in withdraw() (ETH转账.ETH:412)External call before state update on a token transfer hook.
- CRITICALUnprotected transferOwnership (Ownable.sol:64)Ownership can move to an arbitrary address with no two-step accept.
- HIGHCentralized mint authority (Token.sol:88)Owner can mint unlimited supply — common rug-pull pattern.

Frequently asked questions
What is smart contract monitoring?
Smart contract monitoring tracks on-chain events like ownership transfers, large fund movements, and contract state changes in real time, alerting you the moment something unusual happens.
Can Tripwire3 prevent a rug pull?
Tripwire3 can't stop a malicious transaction, but it alerts you the instant a risky event occurs — like an ownership transfer or large withdrawal — so you can react immediately instead of finding out hours later.
Which blockchains does Tripwire3 support?
Ethereum, BSC, and Polygon at launch, with more chains coming based on demand.
Is Tripwire3 free to use?
Yes — the Free plan lets you monitor one contract with email alerts at no cost.
How fast are alerts delivered?
Most alerts reach you in under 60 seconds from the moment the on-chain event is confirmed — fast enough to act before damage spreads.
Do I need to modify my contract?
No. Tripwire3 only reads on-chain data — there's nothing to deploy, no code changes, and no contract permissions required.
What does the Audit Scanner actually check?
Tripwire3 Audit runs Slither (Trail of Bits) against the verified source code and applies contract-type-aware ruleset weighting to surface reentrancy, access-control gaps, centralization risks, oracle manipulation, flash-loan exposure, and other common Solidity vulnerability patterns. Results come with a plain-English AI summary and a 0-100 risk score.
Is the Audit Scanner a replacement for a manual audit?
No. Tripwire3 Audit is an automated first-pass screening tool that finishes in under 90 seconds. It's a strong signal for the most common patterns but does not replace a formal manual audit by a security firm. Critical/high findings surface a clear path to a manual review.
How fast does an audit scan complete?
Most scans finish in 30–90 seconds. You'll get a risk score, severity breakdown, and a plain-English AI summary of every finding as soon as the scan finishes.
