Which chain is this address?
Paste an address below and we will detect its format instantly. Runs entirely in your browser, nothing is sent anywhere. Use it before you bridge to make sure you are sending to a format your destination chain actually supports.
Optional: check against a destination chain
Format check only. This does not look up balances, transaction history or scam reports, and it is not a substitute for confirming the address inside your own wallet.
What this tool detects
Ethereum / EVM
42-character address starting with 0x. Shared by Ethereum, Arbitrum, Base, Optimism, Polygon, BSC and every other EVM chain.
Solana
Base58 string, usually 32-44 characters, no 0x prefix. Not compatible with any EVM chain.
Bitcoin
Legacy addresses start with 1, P2SH with 3, and native SegWit/Taproot with bc1.
Cosmos ecosystem
Bech32 format with a chain-specific prefix, such as cosmos1, osmo1 or juno1.
Frequently asked questions
Is it safe to paste my address into this tool? +
Yes. The check runs entirely in your browser using JavaScript. Nothing you type is sent to via.exchange or anywhere else, and this tool never asks for a private key or seed phrase, only a public address.
Why do I need to check the address format before bridging? +
Blockchains use different address formats. An Ethereum address will not work on Solana, and a Bitcoin address will not work on Cosmos. Sending to a format your destination chain does not use can mean permanently lost funds, so it is worth a five-second check before you bridge.
What if my address is not recognized? +
This tool covers the common formats: EVM chains, Solana, Bitcoin, Cosmos and TON. If an address is not recognized, it may belong to a less common chain, or it may not be a valid address at all. When in doubt, use the address exactly as it is shown in your wallet, ideally by connecting the wallet rather than typing or pasting from memory.
Does this tool tell me if an address is safe or has been hacked? +
No. This tool only checks the format of an address, meaning which chain it is built for. It does not check balances, transaction history or scam reports. It cannot tell you whether an address is trustworthy, only whether it matches the shape of a real address on a given chain.
