OPTIONS

-?

    Print this help message and exit

-version

    Print version and exit

-alertnotify=<cmd>

    Execute command when a relevant alert is received or we see a really long fork (%s in cmd is replaced by message)

-blocknotify=<cmd>

    Execute command when the best block changes (%s in cmd is replaced by block hash)

-assumevalid=<hex>

    If this block is in the chain assume that it and its ancestors are valid and potentially skip their script verification (0 to verify all, default: 66f49ad85624c33e4fd61aa45c54012509ed4a53308908dd07f56346c7939273, testnet: 1efb29c8187d5a496a33377941d1df415169c3ce5d8c05d055f25b683ec3f9a3)

-conf=<file>

    Specify configuration file (default: litecoin.conf)

-daemon

    Run in the background as a daemon and accept commands

-datadir=<dir>

    Specify data directory

-dbcache=<n>

    Set database cache size in megabytes (4 to 16384, default: 450)

-loadblock=<file>

    Imports blocks from external blk000??.dat file on startup

-debuglogfile=<file>

    Specify location of debug log file: this can be an absolute path or a path relative to the data directory (default: debug.log)

-maxorphantx=<n>

    Keep at most <n> unconnectable transactions in memory (default: 100)

-maxmempool=<n>

    Keep the transaction memory pool below <n> megabytes (default: 300)

-mempoolexpiry=<n>

    Do not keep transactions in the mempool longer than <n> hours (default: 336)

-persistmempool

    Whether to save the mempool on shutdown and load on restart (default: 1)

-blockreconstructionextratxn=<n>

    Extra transactions to keep in memory for compact block reconstructions (default: 100)

-pid=<file>

    Specify pid file (default: litecoind.pid)

-prune=<n>

    Reduce storage requirements by enabling pruning (deleting) of old blocks. This allows the pruneblockchain RPC to be called to delete specific blocks, and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with -txindex and -rescan. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, >=550 = automatically prune block files to stay under the specified target size in MiB)
