Token Contract Monitor — Detect Malicious Transactions on Any EVM Token

Introducing Token Contract Monitor for Watchlist. Register a token contract address (e.g. USDT, JPYC) and automatically detect malicious transaction patterns among its transfers.

How It Differs from Wallet Monitoring

Traditional Watchlist monitors wallet addresses and tracks their risk scores. Contract Monitor takes a new approach: it watches all transfers of a token and detects suspicious transaction patterns.

• Wallet Monitoring — Tracks risk score changes for a wallet (existing feature)
• Contract Monitoring — Detects malicious patterns in token transfers (new)

Detection Patterns (5 Types)

1. Known Malicious — Detects when ScamDB-registered drainers or scam addresses are involved in token transfers. Severity: CRITICAL
2. Address Poisoning — Zero or dust-value transfers using addresses with matching first/last characters of legitimate recipients. Tricks users into copy-pasting the wrong address from history. Severity: CRITICAL
3. Relay Chain — Addresses that forward received funds to another address within 1 hour. A classic money laundering technique using intermediary wallets. Severity: HIGH
4. Rapid Distribution — One address sending to 10+ recipients within 1 hour. Often used for phishing campaigns and fraudulent airdrop distribution. Severity: HIGH
5. Large Transfer — Statistically anomalous transfers (top 0.1 percentile). Helps catch suspicious fund movements early. Severity: MEDIUM

Supported Chains

Contract Monitor is available on EVM chains only:

• Ethereum — Blockchain explorer API
• Polygon — Blockchain explorer API
• Avalanche — Blockchain explorer API

Uses the blockchain explorer's contract tracking feature to efficiently fetch all transfers for a specific token.

How It Works

1. Fetch Transfers — Retrieves recent token transfers via blockchain explorer API (up to 5,000)
2. Pattern Analysis — Analyzes each transfer against 5 detection patterns
3. Discovery Registration — Records suspicious addresses as "discoveries" (deduplicated)
4. Notifications — Sends email and webhook alerts for new findings
5. Incremental Updates — Next scan fetches only transfers after the last processed block

Use Cases

• Stablecoin Monitoring — Detect misuse of USDT/USDC and other stablecoins
• Protect Your Token — Catch poisoning attacks targeting your issued token early
• Compliance — Monitor suspicious fund movements for specific tokens

Pricing

• Free / Starter — Contract Monitor not available
• Pro ($19.99/mo) — Contract Monitor included

Get Started

Go to your Watchlist, click "+ Add Address", switch the monitor type to "Token Contract", and enter an EVM token contract address. Pattern detection runs automatically on the regular scan schedule.
