Automatic broadcast and rebroadcast of any transactions from inbound peers is disabled, unless the peer has the 'forcerelay' permission. RPC transactions are not affected. (default: 0) -chainlocknotify= Execute command when the best chainlock changes (%s in cmd is replaced by chainlocked block hash) -coinstatsindex Maintain coinstats index used by the gettxoutsetinfo RPC (default: 0) -conf= Specify path to read-only configuration file. Relative paths will be prefixed by datadir location.

In addition, unused mempool memory is shared for this cache (see -maxmempool). -debuglogfile= Specify location of debug log file. Relative paths will be prefixed by a net-specific datadir location. (-nodebuglogfile to disable; default: debug.log) -includeconf= Specify additional configuration file, relative to the -datadir path (only useable from configuration file, not command line) -loadblock= Imports blocks from external file on startup -maxmempool= Keep the transaction memory pool below megabytes (default: 300) -maxorphantxsize= Maximum total size of all orphan transactions in megabytes (default: 10) -maxrecsigsage= Number of seconds to keep LLMQ recovery sigs (default: 604800) -mempoolexpiry= Do not keep transactions in the mempool longer than hours (default: 336) -minimumchainwork= Minimum work assumed to exist on a valid chain in hex (default: 000000000000000000000000000000000000000000009134566d753c5e08ab88, testnet: 00000000000000000000000000000000000000000000000002ecd6cf5ad0f774) -par= Set the number of script verification threads (-16 to 15, 0 = auto, <0 = leave that many cores free, default: 0) -persistmempool Whether to save the mempool on shutdown and load on restart (default: 1) -pid= Specify pid file. Relative paths will be prefixed by a net-specific datadir location. (default: dashd.pid) -prune= 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, -coinstatsindex, -rescan and -disablegovernance=false. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, >945 = automatically prune block files to stay under the specified target size in MiB) -settings= Specify path to dynamic settings data file. Can be disabled with -nosettings. File is written at runtime and not meant to be edited by users (use dash.conf instead for custom settings). Relative paths will be prefixed by datadir location.

Append =onion to tag any incoming connections to that address and port as incoming Tor connections (default: 127.0.0.1:9996=onion, testnet: 127.0.0.1:19996=onion, regtest: 127.0.0.1:19896=onion) -connect= Connect only to the specified node; -noconnect disables automatic connections (the rules for this peer are the same as for -addnode). This option can be specified multiple times to connect to multiple nodes. -discover Discover own IP addresses (default: 1 when listening and no -externalip or -proxy) -dns Allow DNS lookups for -addnode, -seednode and -connect (default: 1) -dnsseed Query for peer addresses via DNS lookup, if low on addresses (default: 1 unless -connect used) -externalip= Specify your own public address -forcednsseed Always query for peer addresses via DNS lookup (default: 0) -i2pacceptincoming If set and -i2psam is also set then incoming I2P connections are accepted via the SAM proxy. If this is not set but -i2psam is set then only outgoing connections will be made to the I2P network. Ignored if -i2psam is not set. Listening for incoming I2P connections is done through the SAM proxy, not by binding to a local address and port (default: 1) -i2psam= I2P SAM proxy to reach I2P peers and accept I2P connections (default: none) -listen Accept connections from outside (default: 1 if no -proxy or -connect) -listenonion Automatically create Tor onion service (default: 1) -maxconnections= Maintain at most connections to peers (temporary service connections excluded) (default: 125) -maxreceivebuffer= Maximum per-connection receive buffer, *1000 bytes (default: 5000) -maxsendbuffer= Maximum per-connection send buffer, *1000 bytes (default: 1000) -maxtimeadjustment Maximum allowed median peer time offset adjustment. Local perspective of time may be influenced by peers forward or backward by this amount. (default: 4200 seconds) -maxuploadtarget= Tries to keep outbound traffic under the given target (in MiB per 24h). Limit does not apply to peers with 'download' permission. 0 = no limit (default: 0) -natpmp Use NAT-PMP to map the listening port (default: 0) -onion= Use separate SOCKS5 proxy to reach peers via Tor onion services, set -noonion to disable (default: -proxy) -onlynet= Make outgoing connections only through network (ipv4, ipv6, onion, i2p). Incoming connections are not affected by this option. This option can be specified multiple times to allow multiple networks. Warning: if it is used with non-onion networks and the -onion or -proxy option is set, then outbound onion connections will still be made; use -noonion or -onion=0 to disable outbound onion connections in this case. -peerblockfilters Serve compact block filters to peers per BIP 157 (default: 0) -peerbloomfilters Support filtering of blocks and transaction with bloom filters (default: 1) -peertimeout= Specify a p2p connection timeout delay in seconds.

Nodes not using the default ports (default: 9999, testnet: 19999, regtest: 19899) are unlikely to get incoming connections. Not relevant for I2P (see doc/i2p.md). -proxy= Connect through SOCKS5 proxy, set -noproxy to disable (default: disabled) -proxyrandomize Randomize credentials for every proxy connection. This enables Tor stream isolation (default: 1) -seednode= Connect to a node to retrieve peer addresses, and disconnect.

If an initial attempt to connect is unsuccessful after this amount of time, drop it (minimum: 1, default: 5000) -torcontrol=: Tor control port to use if onion listening enabled (default: 127.0.0.1:9051) -torpassword= Tor control port password (default: empty) -upnp Use UPnP to map the listening port (default: 1 when listening and no -proxy) -whitebind=<[permissions@]addr> Bind to the given address and add permission flags to the peers connecting to it. Use [host]:port notation for IPv6. Allowed permissions: bloomfilter (allow requesting BIP37 filtered blocks and transactions), noban (do not ban for misbehavior; implies download), forcerelay (relay transactions that are already in the mempool; implies relay), relay (relay even in -blocksonly mode), mempool (allow requesting BIP35 mempool contents), download (allow getheaders during IBD, no disconnect after maxuploadtarget limit), addr (responses to GETADDR avoid hitting the cache and contain random records with the most up-to-date info). Specify multiple permissions separated by commas (default: download,noban,mempool,relay). Can be specified multiple times. -whitelist=<[permissions@]IP address or network> Add permission flags to the peers connecting from the given IP address (e.g. 1.2.3.4) or CIDR-notated network (e.g. 1.2.3.0/24). Uses the same permissions as -whitebind. Can be specified multiple times. ``` ### Indexing options ```text -addressindex Maintain a full address index, used to query for the balance, txids and unspent outputs for addresses (default: 0) -reindex Rebuild chain state and block index from the blk*.dat files on disk -reindex-chainstate Rebuild chain state from the currently indexed blocks. When in pruning mode or if blocks on disk might be corrupted, use full -reindex instead. -spentindex Maintain a full spent index, used to query the spending txid and input index for an outpoint (default: 0) -timestampindex Maintain a timestamp index for block hashes, used to query blocks hashes by a range of timestamps (default: 0) -txindex Maintain a full transaction index, used by the getrawtransaction rpc call (default: 1) ``` ### Wallet options > 🚧 zapwallettxes > > Dash Core 18.1.0 removed the `-zapwallettxes` startup option and its functionality. This option was originally intended to allow for the fee bumping of transactions that did not signal RBF. This functionality has been superseded with the [abandon transaction capability](../api/remote-procedure-calls-wallet.md#abandontransaction) available via RPC/console or when right-clicking on unconfirmed transactions in Dash-Qt. ```text -avoidpartialspends Group outputs by address, selecting many (possibly all) or none, instead of selecting on a per-output basis. Privacy is improved as addresses are mostly swept with fewer transactions and outputs are aggregated in clean change addresses. It may result in higher fees due to less optimal coin selection caused by this added limitation and possibly a larger-than-necessary number of inputs being used. Always enabled for wallets with "avoid_reuse" enabled, otherwise default: 0. -createwalletbackups= Number of automatic wallet backups (default: 10) -disablewallet Do not load the wallet and disable wallet RPC calls -instantsendnotify= Execute command when a wallet InstantSend transaction is successfully locked. %s in cmd is replaced by TxID and %w is replaced by wallet name. %w is not currently implemented on Windows. On systems where %w is supported, it should NOT be quoted because this would break shell escaping used to invoke the command. -keypool= Set key pool size to (default: 1000). Warning: Smaller sizes may increase the risk of losing funds when restoring from an old backup, if none of the addresses in the original keypool have been used. -rescan= Rescan the block chain for missing wallet transactions on startup (1 = start from wallet creation time, 2 = start from genesis block) -spendzeroconfchange Spend unconfirmed change when sending transactions (default: 1) -wallet= Specify wallet path to load at startup. Can be used multiple times to load multiple wallets. Path is to a directory containing wallet data and log files. If the path is not absolute, it is interpreted relative to . This only loads existing wallets and does not create new ones. For backwards compatibility this also accepts names of existing top-level data files in . -walletbackupsdir= Specify full path to directory for automatic wallet backups (must exist) -walletbroadcast Make the wallet broadcast transactions (default: 1) -walletdir= Specify directory to hold wallets (default: /wallets if it exists, otherwise ) -walletnotify= Execute command when a wallet transaction changes. %s in cmd is replaced by TxID and %w is replaced by wallet name. %w is not currently implemented on windows. On systems where %w is supported, it should NOT be quoted because this would break shell escaping used to invoke the command. ``` ### Wallet fee options ```text -discardfee= The fee rate (in DASH/kB) that indicates your tolerance for discarding change by adding it to the fee (default: 0.0001). Note: An output is discarded if it is dust at this rate, but we will always discard up to the dust relay fee and a discard fee above that is limited by the fee estimate for the longest target -fallbackfee= A fee rate (in DASH/kB) that will be used when fee estimation has insufficient data. 0 to entirely disable the fallbackfee feature. (default: 0.00001) -mintxfee= Fee rates (in DASH/kB) smaller than this are considered zero fee for transaction creation (default: 0.00001) -paytxfee= Fee rate (in DASH/kB) to add to transactions you send (default: 0.00) -txconfirmtarget= If paytxfee is not set, include enough fee so transactions begin confirmation on average within n blocks (default: 6) ``` ### HD wallet options ```text -hdseed= User defined seed for HD wallet (should be in hex).

If rpcwhitelistdefault is set to 1 and no -rpcwhitelist is set, rpc server acts as if all rpc users are subject to empty whitelists. -rpcworkqueue= Set the depth of the work queue to service RPC calls (default: 16) -server Accept command line and JSON-RPC commands ``` ### Statsd options ```text -statsenabled Publish internal stats to statsd (default: 0) -statshost= Specify statsd host (default: 127.0.0.1) -statshostname= Specify statsd host name (default: ) -statsns= Specify additional namespace prefix (default: ) -statsperiod= Specify the number of seconds between periodic measurements (default: 60) -statsport= Specify statsd port (default: 8125) ``` ### Wallet debugging/testing options > 🚧 > > These options are normally hidden and will only be shown if using the help debug option: `dashd --held -help-debug` ```text -dblogsize= Flush wallet database activity from memory to disk log every megabytes (default: 100) -flushwallet Run a thread to flush wallet periodically (default: 1) -privdb Sets the DB_PRIVATE flag in the wallet db environment (default: 1) -unsafesqlitesync Set SQLite synchronous=OFF to disable waiting for the database to sync to disk. This is unsafe and can cause data loss and corruption. This option is only used by tests to improve their performance (default: false) -walletrejectlongchains Wallet will not create transactions that violate mempool chain limits (default: 0) ``` ## Network Dependent Options The following options can only be used for specific network types. These options are provided support development (devnet) and regression test (regtest) networks. ### Devnet Options ```text -highsubsidyblocks= The number of blocks with a higher than normal subsidy to mine at the start of a chain. Block after that height will have fixed subsidy base. (default: 0, devnet-only) -highsubsidyfactor= The factor to multiply the normal block subsidy by while in the highsubsidyblocks window of a chain (default: 1, devnet-only) -llmqchainlocks= Override the default LLMQ type used for ChainLocks. Allows using ChainLocks with smaller LLMQs. (default: llmq_devnet, devnet-only) -llmqdevnetparams=: Override the default LLMQ size for the LLMQ_DEVNET quorum (default: 3:2, devnet-only) -llmqinstantsenddip0024= Override the default LLMQ type used for InstantSendDIP0024. (default: llmq_devnet_dip0024, devnet-only) -llmqmnhf= Override the default LLMQ type used for EHF. (default: llmq_devnet, devnet-only) -llmqplatform= Override the default LLMQ type used for Platform. (default: llmq_devnet_platform, devnet-only) -minimumdifficultyblocks= The number of blocks that can be mined with the minimum difficulty at the start of a chain (default: 0, devnet-only) -powtargetspacing= Override the default PowTargetSpacing value in seconds (default: 2.5 minutes, devnet-only) ``` The quorum names used in these options are: | LLMQ Type | LLMQ Name | | :-------: | --------------------- | | 1 | llmq50_60 | | 2 | llmq400_60 | | 3 | llmq400_85 | | 4 | llmq100_67 | | 5 | llmq60_75 | | 6 | llmq25_67 | | 100 | llmq_test | | 101 | llmq_devnet | | 102 | llmq_test_v17 | | 103 | llmq_test_dip0024 | | 104 | llqm_test_instantsend | | 105 | llmq_devnet_dip0024 | | 106 | llmq_test_platform | | 107 | llmq_devnet_platform | Refer to [this table in DIP-6 - LLMQs](https://github.com/dashpay/dips/blob/master/dip-0006.md#current-llmq-types) for details on each quorum type. ### Regtest Options ```text -budgetparams=:: Override masternode, budget and superblock start heights (regtest-only) -llmqtestinstantsenddip0024= Override the default LLMQ type used for InstantSendDIP0024. Used mainly to test Platform. (default: llmq_test_dip0024, regtest-only) -llmqtestinstantsendparams=: Override the default LLMQ size for the LLMQ_TEST_INSTANTSEND quorums (default: 3:2, regtest-only) -llmqtestparams=: Override the default LLMQ size for the LLMQ_TEST quorum (default: 3:2, regtest-only) -vbparams=::(::(:::)) Use given start/end times for specified version bits deployment (regtest-only). Specifying window, threshold/thresholdstart, thresholdmin, falloffcoeff and mnactivation is optional. ```
