How to Validate an Ethereum Wallet Address Safely

Sending cryptocurrency to an invalid wallet address means permanent loss of funds. No recovery possible.

Our Ethereum Wallet Address Validator helps you instantly check if any ETH, ERC-20, or BEP-20 address is valid before sending funds — so you can transact with confidence.

What Makes an Ethereum Address Valid?

A correct Ethereum address must:

  • Start with 0x
  • Be exactly 42 characters long (including 0x)
  • Contain only hexadecimal characters: 0-9 and A-F
  • Pass checksum validation (if using mixed-case format)

This tool verifies all these rules instantly — helping you catch typos, fake addresses, or copy-paste errors.

Why Address Validation Prevents Costly Mistakes

Common risks include:

  • Typos: Accidentally changing one letter (e.g., “a” → “s”)
  • Clipboard hijacking malware: Replaces real address with hacker’s wallet
  • Fake support scams: Fraudsters send fake QR codes or links

Always validate before sending — even if the address came from a trusted source.

Pro Insight: Combine this with manual checks: Compare first & last 6 characters of the address on both sender and receiver sides.

Works Across Multiple Networks

This validator supports:

  • Ethereum (ETH): Mainnet, Sepolia, Goerli
  • ERC-20 Tokens: USDT, DAI, UNI, LINK, etc.
  • BSC (BEP-20): BNB Smart Chain wallets (same format as ETH)
  • Polygon, Avalanche, Arbitrum: All EVM-compatible chains

One tool for all major networks — no need to switch validators.

Frequently Asked Questions (FAQ)

Get quick answers about validating Ethereum wallet addresses

🔐 How does this wallet validator work?

It checks if the address starts with '0x', is 42 characters long, contains only valid hex characters, and passes Ethereum's checksum rule (if applicable).

💸 Can I lose money without validation?

Yes. If you send funds to an invalid or wrong address, they cannot be recovered. Always validate before sending.

📋 Does it support BSC (BEP-20) addresses?

Yes! BSC uses the same format as Ethereum. Any valid ETH address is also a valid BEP-20 address.

📱 Can I use this on mobile?

Absolutely. Works perfectly on smartphones — great for checking addresses while trading or receiving payments.

🛡️ Is my address data stored or shared?

No. This tool runs entirely in your browser. Your address is never sent to any server or logged anywhere.

🔢 What is a checksum address?

A mixed-case address that includes built-in error protection. Tools like MetaMask display checksummed addresses to prevent typos.

🌐 Can I validate Polygon or Avalanche addresses?

Yes! Since Polygon, Avalanche, Arbitrum, and others use the Ethereum format, this validator works for them too.
