Does this guarantee an address can receive funds?

No. Validation confirms the address is structurally correct and has a valid checksum. It cannot confirm the private key exists, the address is active, or the network accepts it. Always send a test transaction first.

What is an address checksum?

A checksum is extra data embedded in the address that lets you detect typos. Bitcoin Base58Check and Ethereum EIP-55 both embed checksums. If you mistype one character, the checksum fails, catching the error before you send funds.

What is the difference between P2PKH, P2SH, and Bech32?

P2PKH (starts with 1) is the original Bitcoin address format. P2SH (starts with 3) supports multi-signature and script-based payments. Bech32 (starts with bc1) is the modern SegWit format with lower fees and built-in error detection.

Why does Ethereum validation check for mixed-case?

EIP-55 encodes a checksum by capitalizing specific hex letters based on the address hash. An all-lowercase or all-uppercase Ethereum address is technically valid but lacks the checksum. Mixed-case means the EIP-55 checksum is present and correct.

Is my address sent to any server?

No. All validation logic runs entirely in your browser using JavaScript. Nothing is transmitted to any server.

Summary

Paste any crypto wallet address to instantly verify its format, checksum, and network type — 100% client-side.

How it works

Paste a wallet address — the tool detects the network automatically.
For Bitcoin, it decodes Base58Check or Bech32 and verifies the checksum.
For Ethereum, it checks the hex format and validates the EIP-55 mixed-case checksum if present.
For Litecoin and Dogecoin, it applies the same Base58Check logic with their network-specific prefixes.
A pass/fail result with address type details appears instantly.

Use cases

Verify a recipient Bitcoin address before sending funds.
Check if an Ethereum address has a valid EIP-55 mixed-case checksum.
Confirm a Bech32 (SegWit) Bitcoin address is well-formed.
Validate a Litecoin or Dogecoin address format.
Spot-check user-submitted addresses in a wallet integration.
Teach yourself the structural differences between address types.
