Wallet Address Tools
Validate the format of any crypto wallet address and generate a QR code to share it safely - fully in your browser.
Supported address formats
This tool checks address format only - it confirms the address matches the expected pattern for Bitcoin (legacy, P2SH and Bech32), Ethereum-style chains (Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche - they all share the same 0x format), Solana and Tron. It cannot confirm an address is active, owned by anyone in particular, or safe to send funds to - always double check the full address character by character before sending any transaction.
Frequently Asked Questions
Does this tool check if a wallet address is safe?
No, it only checks that the address matches the correct format for its blockchain. It cannot confirm the address is active, legitimate, or safe to send funds to.
Why do Ethereum, BNB Chain and Polygon addresses look the same?
They are all EVM-compatible chains and share the same 0x address format, so the same address can technically exist on any of them.
Is my address sent anywhere when I use this tool?
No, the format check and QR code generation both run entirely in your browser; nothing is sent to a server.
What should I do before sending crypto to an address?
Always compare the full address character by character, ideally by scanning a QR code, and send a small test amount first for any large or new transaction.
Is the wallet address validator free to use?
Yes, checking a wallet address format and generating a QR code is completely free and runs entirely in your browser, with no signup required.
How do I check if a crypto wallet address is valid?
Paste the address above; this tool automatically detects whether it matches a valid Bitcoin, Ethereum-style, Solana, or Tron address format.
