Address starting with “0x”
- Coin
- Ethereum and every EVM chain (ETH, BNB Smart Chain, Polygon, Arbitrum, Base, Avalanche C-Chain …)
- Type
- 20-byte account or contract, hex, optional EIP-55 checksum in the letter case
- Length
- 42 characters (0x + 40 hex)
- Confused with
- 0x followed by 64 hex characters is a different thing: a Sui or Aptos address, a transaction hash, or a private key. The address alone does not say which EVM chain is meant.
Ask the recipient for the network name. The same 0x… address exists on every EVM chain, each with its own balance.

Watch out
- A 0x… address is valid on every EVM chain (Ethereum, BNB Smart Chain, Polygon, Arbitrum, Base …). The format cannot tell which chain the recipient watches — ask for the network name.
What this does not proveA valid format only means the address is well-formed. It does not show who controls it or that it is the address the recipient gave. Compare the whole address with the source and send a small test amount first.
