0x123D

0x123D is a short hexadecimal string that begins with the common blockchain prefix 0x. In many blockchain ecosystems, 0x-prefixed values denote hex data, including addresses, transaction data, or identifiers. However, as written, 0x123D does not constitute a complete Ethereum or other standard address, since an Ethereum address is typically 40 hexadecimal characters following 0x. Therefore, on its own it is not a valid canonical address.

In practice, 0x123D can appear in several roles. It may be part of a longer value truncated for readability, or used as a placeholder constant in example code. It could also appear as a fragment of a transaction input, a portion of a hash, or as a short alias within documentation. A legitimate Ethereum function selector, by contrast, is 4 bytes (eight hex digits) and would be shown as 0x followed by eight hex characters, not four.

To determine what 0x123D refers to in a given context, one should consult the surrounding documentation or source code. If the goal is to identify an on-chain entity, the complete address is required and can be looked up in a blockchain explorer such as Etherscan or its equivalents for other networks. If the value is intended as data, decoding it according to the expected ABI or data encoding scheme is appropriate.

As of its general usage, 0x123D has no widely recognized association with a specific contract, token, or account. It functions primarily as an example string or partial identifier rather than a known entity.
