Supported Address Formats
About this tool
Cryptocurrency addresses follow specific format rules depending on the coin (Bitcoin, Ethereum, and others each have their own address structure and checksum). This tool validates whether an address is correctly formatted for its cryptocurrency, helping catch typos or malformed addresses before you send funds to them.
How to use this tool
- Select blockchain typeChoose the cryptocurrency network tied to the address format.
- Paste wallet addressInput full destination address exactly as received.
- Run format/checksum validationVerify structural correctness and checksum where applicable.
- Confirm before transferUse validation as safety step before irreversible transaction.
Why checking a crypto address matters
Crypto transfers cannot be reversed. A mistyped address that still passes the network’s checks, or a coin sent on the wrong network, can be lost for good. Validating the format catches typos and addresses that belong to a different coin.
A valid format does not prove the address belongs to the person you mean to pay. Copy and paste addresses rather than typing them, check the first and last few characters, and send a small test amount first for large transfers.
Key features
- Catches malformed crypto addresses before fund transfer.
- Reduces typo risk in irreversible blockchain transactions.
- Supports quick sanity checks across common address standards.
- Useful for traders, exchanges, and support teams.
Common uses
- Validating copied wallet address before withdrawal.
- Checking user-submitted deposit addresses in support flow.
- Debugging failed transfer due to address format errors.
- Training users on chain-specific address differences.
Tips for better results
- Always verify network/chain matches address standard.
- Use copy-paste and checksum validation to avoid manual typos.
- Perform small test transfer for first-time recipients.
- Beware clipboard malware that swaps crypto addresses.
Mistakes to avoid
- Assuming valid format confirms wallet ownership.
- Sending funds on wrong chain despite valid-looking address.
- Skipping final character checks after copy operations.
- Trusting screenshots instead of text-based address verification.
Frequently asked questions
No - it only checks that the address follows the correct format and checksum rules for that cryptocurrency. It cannot confirm the address is actually in use, owned by anyone specific, or able to receive funds successfully.
Common formats like Bitcoin and Ethereum addresses are typically supported - check the tool for the specific list of coins it validates.
Cryptocurrency transactions are irreversible - sending to a malformed or mistyped address can mean permanently losing the funds, so a quick format check before sending is a cheap safety step.
Bitcoin legacy addresses start with 1, script addresses with 3 and SegWit (bech32) addresses with bc1. Ethereum addresses start with 0x followed by 40 hex characters, and the same format is used on many EVM networks.
An Ethereum-format address is valid on Ethereum, BNB Smart Chain, Polygon and other EVM chains, so funds sent on the wrong network may not arrive where expected. Always confirm the network as well as the address.
Some malware replaces copied crypto addresses on the clipboard. After pasting, check the first and last several characters against the original, and send a small test amount first for large transfers.
