Ethereum ERC20 and BNB Token Addresses
Ethereum and BNB Smart Chain addresses usually share the same format: 0x followed by 40 hexadecimal characters. Matching formats do not mean matching networks or balances.
ERC20 is an Ethereum token standard. A token contract address identifies a specific smart contract and must not be confused with a recipient wallet address.
What Ethereum ERC20 means
ERC20 defines common token functions and events such as transfer, balanceOf, approve and Transfer. Token names and symbols are not unique, so the contract address on the correct network is the primary identifier.
Ethereum and BSC address format
An EVM address represents 20 bytes and is rendered as 0x plus 40 hex characters. Mixed case may encode an EIP-55 checksum. BNB Smart Chain uses the same format, but ETH, BNB and token balances remain on separate networks.
Wallet address vs token contract
| Object | Identifies | Verify with |
|---|---|---|
| Wallet address | Sender or recipient account | Explorer for the selected network |
| Token contract | A token smart contract | Official source and explorer |
| Transaction hash | One transaction | Explorer for the selected network |
| BNB token address | BEP-20 contract on BSC | BSC explorer and official source |
How to verify a token address
- Open an explorer for the correct network.
- Check whether the address contains contract code.
- Compare every character with the project’s official documentation.
- Review symbol, decimals, source verification and creation history.
- Never trust a name, logo or chat message alone.
Explorer, RPC and node providers
People use explorers, while applications query nodes through RPC to read contract code, metadata, balances and Transfer events. Neither an explorer nor RPC can automatically prove that a token is trustworthy.
Ethereum and BNB address FAQ
What does an ERC20 address look like?
It uses the EVM 0x plus 40-hex-character format; “ERC20 address” often means a token contract.
Are Ethereum and BSC addresses the same?
Their format and derived account may match, but the networks, balances and transactions are separate.
How is a token address different from a wallet?
A token address points to smart-contract code; a wallet address identifies an account or recipient.
Can a network be identified from 0x alone?
No. Multiple EVM networks use this format.
What should be checked before sending?
Network, recipient, token contract, service support, amount and native fee balance.
