```
public class ZcashSdk

                    
```
Wrapper for all the constant values in the SDK. It is important that these values stay fixed for all users of the SDK. Otherwise, if individual wallet makers are using different values, it becomes easier to reduce privacy by segmenting the anonymity set of users, particularly as it relates to network requests.

- Method Detail
  - getMINERS_FEE
```
 final Zatoshi getMINERS_FEE()
```
    Miner's fee in zatoshi.
  - getMAX_MEMO_SIZE
```
 final Integer getMAX_MEMO_SIZE()
```
    The maximum length of a memo.
  - getEXPIRY_OFFSET
```
 final Integer getEXPIRY_OFFSET()
```
    The amount of blocks ahead of the current height where new transactions are set to expire. This value is controlled by the rust backend but it is helpful to know what it is set to and should be kept in sync.
  - getPOLL_INTERVAL_SHORT
```
 final Long getPOLL_INTERVAL_SHORT()
```
    A short amount of time, in milliseconds, to poll for new blocks used typically when a block synchronization error occurs.
  - getPOLL_INTERVAL
```
 final Long getPOLL_INTERVAL()
```
    Default amount of time, in milliseconds, to poll for new blocks. Typically, this should be about half the average block time.
  - getBLOCK_INTERVAL_MILLIS
```
 final Long getBLOCK_INTERVAL_MILLIS()
```
    Estimate of the time between blocks.
  - getMAX_BACKOFF_INTERVAL
```
 final Long getMAX_BACKOFF_INTERVAL()
```
    The default maximum amount of time to wait during retry backoff intervals. Failed loops will never wait longer than this before retyring.
  - getDEFAULT_SHIELD_FUNDS_MEMO_PREFIX
```
 final String getDEFAULT_SHIELD_FUNDS_MEMO_PREFIX()
```
    The default memo to use when shielding transparent funds.
  - getDEFAULT_ALIAS
```
 final String getDEFAULT_ALIAS()
```
    The default alias used as part of a file name for the preferences and databases. This enables multiple wallets to exist on one device, which is also helpful for sweeping funds.
  - getALIAS_MIN_LENGTH
```
 final Integer getALIAS_MIN_LENGTH()
```
    The minimum alias length to be valid for our use.
  - getALIAS_MAX_LENGTH
```
 final Integer getALIAS_MAX_LENGTH()
```
    The maximum alias length to be valid for our use.
