Cryptocurrency Addresses
NOTE: Data Identifiers are legacy DLP features that will no longer be supported by the end of June 2025, it is recommended to use a classification-based approach for all your DLP use cases. To assist with migrating your DLP policies from Data Identifiers to Classification, refer to the Migration Guide.
Skyhigh CASB supports the following definitions, validation, and keyword information for Cryptocurrency Address data identifiers.
NOTE: Skyhigh CASB regex includes an extra backslash to conform with JSON string structure. Naked regex would have only one backslash, but regex in strings requires the extra backslash to be escaped. For more information, see https://www.regular-expressions.info/java.html.

Bitcoin Address |
A Bitcoin address, or simply address, is an identifier of 26-35 alphanumeric characters, beginning with the number 1 or 3, that represents a possible destination for a bitcoin payment. | "[13][a-km-zA-HJ-NP-Z1-9]{25,34}" |
|
| Dash Pay (DASH) Address | A Dash address is an identifier of 26-35 alphanumeric characters, beginning with the alphabetic character X, that represents a possible destination for a Dash payment. | "X[1-9A-HJ-NP-Za-km-z]{33}" |
|
| Ethereum (ETH) Address | An Ethereum address represents an account. For EOA, the address is derived as the last 20 bytes of the public key controlling the account, e.g., `cd2a3d9f938e13cd947ec05abc7fe734df8dd826. This is a hexadecimal format (base 16 notation), which is often indicated explicitly by appending 0x to the address. Web3.js and console functions accept addresses with or without this prefix, but for transparency we encourage their use. Since each byte of the address is represented by two hex characters, a prefixed address is 42 characters long. | "0x[0-9a-fA-F]{40}" |
|
| Litecoin (LTC) Address | A Litecoin address is an identifier of 26-35 alphanumeric characters, beginning with the alphabet L, that represents a possible destination for a Litecoin payment. | "L[a-km-zA-HJ-NP-Z1-9]{26,33}" |
|
| Monero (XMR) Address | When you send Monero to someone you only need one piece of information, and that is their Monero address. A raw Monero address is a set of 95 characters starting with a '4'. | "4[0-9AB][123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz]{93}" |
|
| Ripple (XRP) Address | Accounts in the XRP Ledger are identified by a base58 XRP Ledger Address. The address is derived from the account's master public key, which is in turn derived from a secret key. | "r[1-9A-HJ-NP-Za-km-z]{25,33}" |
