Are Ethereum addresses case sensitive? ›

No, Ethereum addresses are not case sensitive.

Ethereum addresses do not differentiate between capital and lower-case letters. The system may display the address in capital or lower-case letters after registration. Although capital and lower-case letters are not differentiated, it is possible that an address with even just a single letter difference exists.

Ethereum (ETH) and other EVM (Ethereum Virtual Machine) network addresses, such as those used on Arbitrum, Optimism, Base, Blast, and Fantom, are not case-sensitive and can be entered in any mix of upper or lower case without affecting the transaction.

While Bitcoin addresses are not case-sensitive, some wallets use case-sensitive addresses. One example is the Ethereum wallet. Ethereum addresses are case-sensitive, meaning whether you use uppercase or lowercase letters in the address matters. It is important to always check the address before sending any Ethereum.

On Ethereum and other networks compatible with the Ethereum Virtual Machine (EVM), public addresses all share the same format: they begin with 0x, and are followed by 40 alphanumeric characters (numerals and letters), adding up to 42 characters in total. They're also not case sensitive.

In hexadecimal, 2 digits represent a byte, meaning addresses contain 40 hexadecimal digits. An example of an Ethereum address is 0xb794f5ea0ba39494ce839613fffba74279579268. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce.

The exchange will make it clear what type of chain they are using; however, one easy way to differentiate between these two is by the way the address is structured. An ERC20 Address only starts with '0' and 'x'. For example: 0xbc6e. A TRC20 Address only begins with a capital 'T'.

Solana (SOL) addresses, for instance, are case-sensitive. Using the wrong case when typing a Solana address could mean losing your funds permanently. When sending or receiving SOL or SPL tokens, always double-check that the address matches the destination precisely.

At first glance, Binance Smart Chain (BSC) and Ethereum look very similar. DApps and tokens built on BSC are compatible with the Ethereum Virtual Machine (EVM). You may have noticed that your public wallet addresses are the same on both blockchains. There are even projects that work on both networks.

Do capital letters affect email addresses? As mentioned earlier, capital letters do not affect email addresses in any way. You can capitalize the email or not capitalize any of the letters at all. As long as the email address is spelled correctly, it will work properly.

No, the address need not be in all capital letters. However, the address must be written in a legible manner so that the receiving postal administration can read the address. All capital letters can help but they are not necessary.

Ether is a common noun and should not be capitalized unless at the beginning of a sentence.
