#maxtimeadjustment=1

# Tries to keep outbound traffic under the given target per 24h. Limit
# does not apply to peers with 'download' permission or blocks
# created within past week. 0 = no limit (default: 0M). Optional

# Tor control port to use if onion listening enabled (default:
# 127.0.0.1:9051)
#torcontrol=<ip>:<port>

# Tor control port password (default: empty)

# 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,
# and unlimited transaction announcements), 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.
#whitebind=<[permissions@]addr>

# 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

### Wallet options


# What type of addresses to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m", default: "bech32")
#addresstype=1

# 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.
#avoidpartialspends=1

# What type of change to use ("legacy", "p2sh-segwit", "bech32", or
# "bech32m"). Default is "legacy" when -addresstype=legacy, else it
# is an implementation detail.
#changetype=1

# The maximum feerate (in BTC/kvB) at which transaction building may use
# more inputs than strictly necessary so that the wallet's UTXO
# pool can be reduced (default: 0.0001).
#consolidatefeerate=<amt>

# Do not load the wallet and disable wallet RPC calls
disablewallet=1

# The fee rate (in BTC/kvB) 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
#discardfee=<amt>

# A fee rate (in BTC/kvB) that will be used when fee estimation has
# insufficient data. 0 to entirely disable the fallbackfee feature.
# (default: 0.00)
#fallbackfee=<amt>

# 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.
#keypool=<n>

# Spend up to this amount in additional (absolute) fees (in BTC) if it
# allows the use of partial spend avoidance (default: 0.00)
#maxapsfee=<n>

# Fee rates (in BTC/kvB) smaller than this are considered zero fee for
# transaction creation (default: 0.00001)

#spendzeroconfchange=1

# If paytxfee is not set, include enough fee so transactions begin
# confirmation on average within n blocks (default: 6)
#txconfirmtarget=<n>

# 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>.
#wallet=<path>

# Make the wallet broadcast transactions (default: 1)
#walletbroadcast=1

# Specify directory to hold wallets (default: <datadir>/wallets if it
# exists, otherwise <datadir>)
#walletdir=<dir>

# Execute command when a wallet transaction changes. %s in cmd is replaced
# by TxID, %w is replaced by wallet name, %b is replaced by the
# hash of the block including the transaction (set to 'unconfirmed'
# if the transaction is not included) and %h is replaced by the
# block height (-1 if not included). %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.
#walletnotify=<cmd>

# Send transactions with full-RBF opt-in enabled (RPC only, default: 1)
#walletrbf=1


### Debugging/Testing options

# network challenge)
#signetchallenge=1

# Specify a seed node for the signet network, in the hostname[:port]

#minrelaytxfee=<amt>

# Relay non-P2SH multisig (default: 1)
#permitbaremultisig=1

# Add 'forcerelay' permission to whitelisted inbound peers with default
# permissions. This will relay transactions even if the
# transactions were already in the mempool. (default: 0)
#whitelistforcerelay=1

### RPC server options


# Accept public REST requests (default: 0)
rest=1

# Allow JSON-RPC connections from specified source. Valid for <ip> are a
# single IP (e.g. 1.2.3.4), a network/netmask (e.g.
# 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This
# option can be specified multiple times
rpcallowip=192.168.1.0/24

# Username and HMAC-SHA-256 hashed password for JSON-RPC connections. The

# rpcuser=<USERNAME>/rpcpassword=<PASSWORD> pair of arguments. This
# option can be specified multiple times
#rpcauth=<userpw>

# 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

#rpcwhitelist=<whitelist>

# 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
