Security Gate — Protect Your Crypto From Scams
5-Point Transaction Verification System — Sending & Receiving Protection
Scams, rug pulls, and fraudulent tokens are the #1 way people lose cryptocurrency. Security Gate flags them before they happen — on every transaction, automatically, in under 1 second. It informs you; you decide. It never freezes or holds your tokens, and the app has zero third-party integrations.

How Security Gate Protects You
Every transaction is automatically scanned through 5 independent security checks — completing in under 1 second before you confirm.
Under 1 Second
5 checks run in parallel. Results displayed before you confirm.
Send & Receive
Most wallets only check sending. Security Gate protects receiving too.
Non-Custodial
You always have the final decision. Security Gate informs — it never freezes, holds, or moves your tokens. Non-custodial always, no token-freezing risk.
The Problem
- Fake tokens airdropped to your wallet
- Phishing links trick you into "selling"
- Smart contract exploits steal funds
- You receive tokens worth zero
- By the time you notice, funds are gone
The Solution
- Analyzed before you interact with it
- Real-time risk alerts on arrival
- Malicious code detected automatically
- Fake token clones identified instantly
- You're warned before any damage
Why Receiving Protection Matters
The 5 Security Checks When You Send Crypto
When you initiate a transaction, Security Gate runs all 5 checks simultaneously.
Address Validation
Sending to wrong address = funds lost forever. Blockchain cannot reverse transactions.
What It Checks
- Format correct for blockchain
- Address matches blockchain standards
- Checksum valid
- No typos detected
- Address is real (not made-up format)
Real Examples
Format correct (0x + 40 hex characters), checksum valid — clear to proceed.
Missing character: "Address format incorrect. Is this intentional?"
Fraud Detection
Scammers reuse addresses. One database lookup can block thousands of known bad actors.
What It Checks
- Address on known scam list?
- Phishing address check
- Darkweb activity scan
- Association with stolen funds
- Sanctions list check
Real Examples
"This address executed 5 rug pulls in past 6 months." Blocked by default.
"Known legitimate address." Allows without warning.
Token Contract Verification
Scammers create FAKE tokens with the same name. Both may show as "USDC" — Security Gate verifies the actual contract address.
What It Checks
- Is the smart contract real?
- Legitimate or fake clone?
- Known exploits in the code?
- Contract verified (code visible)?
- Matches what you think you're sending?
Real Examples
"Verified contract. This is real USDC." Contract matches known address.
"This is NOT real USDC. This is a cloned token." Blocks/warns you.
Receiver Address History
Real addresses have history. Scam addresses are often brand new and discarded after the scam.
What It Checks
- How old is this address?
- What's the transaction history?
- Dormant or active pattern?
- Any suspicious patterns?
- Contract or EOA (externally owned)?
Real Examples
4 years old, 5,000+ transactions, normal activity pattern — Low risk.
"Created 2 hours ago, 0 transactions. Is this intentional?" — Medium risk.
Gas Estimation
Prevents overpaying on gas, getting stuck in mempool, or front-running attacks.
What It Checks
- Network congestion level
- Exact gas fee amount
- Transaction confirmation time
- Whether you're overpaying
- Speed options (standard, fast, urgent)
Real Examples
Polygon: Gas ~$0.10 · Confirmation ~2 seconds · Send immediately.
Ethereum high congestion: Standard $50 (~10 min) · Fast $120 (~2 min).
The 5 Security Checks When You Receive Crypto
Most wallets don't protect receiving. Security Gate does — automatically on every incoming token.
Sender Address Verification
Identifies who is sending you crypto. Checks if the sender is a known project, company, or person. Flags new or suspicious addresses before tokens land.
Uniswap official distribution: "Verified legitimate sender." Safe to claim.
Unknown address created 1 hour ago: "Unknown sender. Don’t interact until verified."
Impersonating MetaMask: "Sender is impersonating MetaMask. Phishing attempt." Blocked.
Token Fraud Detection
Detects rug pull tokens, clones, malicious code, and tokens that drain your wallet if approved. Scam tokens look real in your wallet — Security Gate sees through them.
Real ENS airdrop: "Legitimate protocol. Can safely interact."
"MOON" rug pull token: "Creator has executed 3 rug pulls. Tokens worthless." Blocked.
"YIELD" malicious token: "Approving this token would drain your wallet." Blocked.
Contract Authentication
Verifies the token contract is legitimate. Compares contract address to known legitimate addresses. Blocks fake versions of real tokens like UNI, USDC, ETH.
Verified USDC: "This is real USDC." Code verified on Etherscan.
New project: "Contract unverified. Manually verify before use."
Fake UNI: "Real UNI is 0x1f98... This contract is different." Blocked.
Source of Funds Analysis
Traces where the tokens came from. Receiving stolen or tainted funds can put you at legal risk. Security Gate warns you before you accept them.
Exchange withdrawal (Coinbase): "Source is legitimate exchange." Safe to accept.
Tokens from rug pull: "Tokens came from a rug pull — may not be tradeable."
Stolen DeFi funds: "Funds trace to known theft/exploit." Blocked with legal warning.
Risk Scoring
Combines all 4 checks into an overall risk score (0–100%). Provides a clear recommendation: accept, verify, or block.
0% Risk — Auto-approved. Legitimate airdrop from verified protocol.
60% Risk — Quarantine. Unknown token, unverified contract, unknown origin.
95% Risk — Blocked. Known scammer, rug pull token, malicious code.
Risk Score Interpretation
Security Gate combines all checks into a single score. Here's what each level means.
Accept
Verify first
Don't interact

Step-by-Step Guide: Handling Risky Tokens
Three of the most common scenarios you'll encounter — and exactly what to do.
You Receive an Unknown Airdrop Token
50% Risk ScoreStep 1: Don't Panic
Just receiving a token ≠ you're hacked. Scammers send unsolicited tokens constantly.
Step 2: Don't Interact
Do NOT click links, approve the token, swap it, or visit websites about it.
Step 3: Research
Search "[token name] scam". Check CoinGecko, official Discord, verified Twitter.
Step 4: Decide
If legitimate: trade it. If suspicious: leave it. If confirmed scam: ignore completely.
Someone Sends ETH Then Asks for It Back
Refund Scam AlertStep 1: Recognize the Scam
Official support NEVER asks for money via DM. Real mistakes are handled by exchanges.
Step 2: Block the Sender
Block the address immediately. Report them on Discord/Twitter.
Step 3: Keep the ETH
The ETH sent to you is yours. Don't send it to a stranger's address.
Step 4: Report to Meton
Forward the message to Meton support so the address gets blacklisted.
You Receive "500% APY" Ponzi Tokens
90% Risk — Ponzi SchemeStep 1: Don't Stake
Do NOT deposit money into the staking contract or approve the token for any contract.
Step 2: Understand the Scam
"Guaranteed" returns in crypto always mean scam. 500% APY is mathematically impossible.
Step 3: Get Rid of It
Leave it in wallet (harmless), try to swap (might fail), or just ignore it.
Step 4: Report It
Report the contract address to Meton and warn others in the community Discord.
Wallet Protection Best Practices
Security Gate catches ~95% of scams. These habits protect the remaining 5%.
Protect Your Seed Phrase
Write on paper, store in 2–3 secure locations. Never in email, cloud, or screenshots. Never share with anyone.
Heed Security Gate Alerts
Yellow = verify before proceeding. Red = usually don't proceed. Overriding a Red alert means accepting full risk.
Diversify Storage
Cold storage 50–60% (hardware wallet), Warm 20–30% (Meton), Hot 10–20% (exchange for trading).
Verify External Links
Type URLs directly — never click links from DMs, emails, or unsolicited offers. Check domain matches exactly.
Use Multiple Wallets
Separate wallets for storage, active trading, and experimental DeFi. Limits maximum loss exposure.
Enable Biometrics
Fingerprint or Face ID on every transaction. Even if your device is stolen, funds stay protected.
Monitor Your Balance
Daily 2-minute check. Weekly 5-minute review. Monthly full audit. Catch unauthorized activity early.

Security Gate Questions
Common questions about how Security Gate protects you.
Can Security Gate Block Legitimate Transactions?
Rarely. If it does, you can override (except high-risk). We're conservative on purpose — better to warn than allow harm.
Does Security Gate Share My Data?
No. All checks happen on-device or through privacy-preserving APIs. Meton never sees your addresses or transactions.
What If I Disagree With a Security Gate Alert?
You can override yellow/red alerts (except critical). But we recommend researching first before overriding.
Does Security Gate Protect Against All Scams?
No, but ~95%. No system is 100% safe. Use good judgment + Security Gate = maximum safety.
Can My Seed Phrase Be Stolen Through Security Gate?
No. Meton is non-custodial. Your seed phrase stays on your device. Security Gate cannot access it.
What If Someone Has My Address?
Just having your address is not dangerous. They can see your balance but cannot steal funds. Your private key is what matters.
Does Security Gate Cost Extra?
No. Built into Meton. Free for all users. No additional fees ever.
Can I Turn Off Security Gate?
No. It's always on. We strongly recommend never disabling it — it's your primary protection layer.
How Often is Security Gate Updated?
Continuously. New scam patterns are detected and added to the database daily.
What if Security Gate Flags a Real Address?
Unlikely but possible. Whitelist legitimate addresses you use often. Report false positives to security@metonwallet.com.
