Wallet Security on Monad

Learn about address poisoning, dust attacks, and other blockchain scams. Protect your wallet on Monad with best practices.

Overview

Blockchain scams are becoming increasingly sophisticated. This guide covers the most common attack vectors on EVM chains including Monad, and how to protect yourself. The Monad AI Explorer includes built-in detection for many of these threats.

Address Poisoning

Address poisoning is one of the most common blockchain scams. Here's how it works:

  1. The attacker generates an address with the same first and last 4 characters as one of your real contacts
  2. They send a dust transaction (near-zero value) from the lookalike address to your wallet
  3. The fake address appears in your transaction history
  4. When you later want to send to your real contact, you accidentally copy the fake address from your history

Protection

Always verify the full address (all 42 characters) before sending funds. Never copy addresses from transaction history without checking every character.

Dust Attacks

Dust attacks involve sending tiny amounts (less than 0.001 MON) to many addresses. Goals include:

  • Tracking — linking multiple wallets to the same person
  • Phishing — the "from" address may look like a known service
  • Address poisoning — a variant of the attack described above

Airdrop Scams

Fake tokens appearing in your wallet with names mimicking real tokens. These may contain malicious approve() functions that drain your wallet when you try to interact with them.

  • Never interact with tokens you didn't buy or earn
  • Don't try to "sell" unknown tokens — this is often the trap
  • Check token contract addresses against official sources

Honeypot Contracts

Honeypot tokens let you buy but not sell. The contract is designed to trap funds:

  • Transfer functions are blocked for non-owner addresses
  • Fake liquidity or trading volume creates false confidence
  • Often promoted as "the next 100x gem" on social media

Best Practices

  • Always verify the full address (all 42 characters) before sending
  • Use an address book / contacts feature in your wallet
  • Be suspicious of unsolicited incoming tokens or tiny transfers
  • Check token contract approvals regularly and revoke unnecessary ones
  • Never share your seed phrase or private keys with anyone
  • Use Monad AI Explorer to analyze any address before interacting — the AI automatically detects address poisoning, dust attacks, and suspicious approval patterns

Free Security Scanning

Monad AI Explorer is the only Monad explorer with built-in security analysis. Paste any address and ask the AI: "Is this address safe?" — it will check for address poisoning (lookalike addresses), dust attack patterns, suspicious approvals, and bot activity indicators. No sign-up required.

FAQ

What is address poisoning?
An attack where scammers send dust from an address that looks similar to your real contacts (matching first/last 4 characters), hoping you'll accidentally copy the fake address later.
How do I check if an address is suspicious?
Use Monad AI Explorer's AI agent — paste any address and ask it to analyze for suspicious activity. It checks for dust attacks, address poisoning, and unusual transaction patterns.
Can I get my funds back if I send to a wrong address?
Unfortunately, blockchain transactions are irreversible. Once confirmed, there is no way to reverse a transfer. This is why address verification is critical.
Are these attacks specific to Monad?
No. These attacks affect all EVM blockchains including Ethereum, BSC, Polygon, and Monad. The security best practices are the same across all chains.
