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 =

Default duration (in seconds) of manually configured bans (default:
86400)
-bind=<addr>[:<port>][=onion]
Bind to given address and always listen on it (default: 0.0.0.0). Use
[host]:port notation for IPv6. 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=<ip>
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

unless -connect used)
-externalip=<ip>
Specify your own public address

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=<ip:port>
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)

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=<ip:port>
Use separate SOCKS5 proxy to reach peers via Tor onion services, set
-noonion to disable (default: -proxy)
-onlynet=<net>
Make outgoing connections only through network <net> (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=<n>

Specify socket connection timeout in milliseconds. If an initial attempt
to connect is unsuccessful after this amount of time, drop it
(minimum: 1, default: 5000)
-torcontrol=<ip>:<port>
Tor control port to use if onion listening enabled (default:
127.0.0.1:9051)
-torpassword=<pass>
Tor control port password (default: empty)
-upnp

-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

the same permissions as -whitebind. Can be specified multiple
times.
Indexing options#

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.

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
-zapwallettxesstartup 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 available via RPC/console or when right-clicking on unconfirmed transactions in Dash-Qt.
-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=<n>
Number of automatic wallet backups (default: 10)
-disablewallet
Do not load the wallet and disable wallet RPC calls
-instantsendnotify=<cmd>
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=<n>
Set key pool size to <n> (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=<mode>
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=<path>
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 <walletdir>. 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
<walletdir>.
-walletbackupsdir=<dir>
Specify full path to directory for automatic wallet backups (must exist)
-walletbroadcast
Make the wallet broadcast transactions (default: 1)
-walletdir=<dir>
Specify directory to hold wallets (default: <datadir>/wallets if it
exists, otherwise <datadir>)
-walletnotify=<cmd>
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#
-discardfee=<amt>
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=<amt>
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=<amt>
Fee rates (in DASH/kB) smaller than this are considered zero fee for
transaction creation (default: 0.00001)
-paytxfee=<amt>
Fee rate (in DASH/kB) to add to transactions you send (default: 0.00)
-txconfirmtarget=<n>
If paytxfee is not set, include enough fee so transactions begin
confirmation on average within n blocks (default: 6)
HD wallet options#
-hdseed=<hex>
User defined seed for HD wallet (should be in hex). Only has effect
during wallet creation/first start (default: randomly generated)
-mnemonic=<text>
User defined mnemonic for HD wallet (bip39). Only has effect during

then connects normally using the
rpcuser=<USERNAME>/rpcpassword=<PASSWORD> pair of arguments. This
option can be specified multiple times
-rpcbind=<addr>[:port]
Bind to given address to listen for JSON-RPC connections. Do not expose
the RPC server to untrusted networks such as the public internet!
This option is ignored unless -rpcallowip is also passed. Port is
optional and overrides -rpcport. Use [host]:port notation for
IPv6. This option can be specified multiple times (default:
127.0.0.1 and ::1 i.e., localhost, or if -rpcallowip has been
specified, 0.0.0.0 and :: i.e., all addresses)

they are set-intersected. See -rpcwhitelistdefault documentation
for information on default whitelist behavior.
-rpcwhitelistdefault
Sets default behavior for rpc whitelisting. Unless rpcwhitelistdefault
is set to 0, if any -rpcwhitelist is set, the rpc server acts as
if all rpc users are subject to empty-unless-otherwise-specified
whitelists. 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=<n>
Set the depth of the work queue to service RPC calls (default: 16)
