New RPC Commands

Bitcoin Knots includes several RPC commands not available in Bitcoin Core.

Mempool Commands​

listmempooltransactions​

Returns all transactions in the mempool, with an entry_sequence value per entry so you can poll for new entries (an alternative to ZMQ notifications):

# All mempool transactions (txids + sequence numbers)
bitcoin-cli listmempooltransactions

# Only entries since a given mempool sequence, with full decoded transactions
bitcoin-cli listmempooltransactions 12345 true

Parameters: start_sequence (default 0 — all transactions) and verbose (default false).

maxmempool​

New in v29.3: change the memory allocated to the mempool at runtime, without restarting the node:

# Set the mempool allocation to 150 MB
bitcoin-cli maxmempool 150

Takes a single megabytes argument. The current value is reported in the maxmempool field of getmempoolinfo.

getmempoolinfo (Enhanced)​

Knots extends getmempoolinfo with an optional fee-histogram argument. Pass true for default fee-rate buckets, or an array of custom bucket boundaries:

bitcoin-cli getmempoolinfo true

The response then includes a fee_histogram object (not available in Bitcoin Core).

Block Commands​

getblocklocations​

Get the file locations of a block:

bitcoin-cli getblocklocations "blockhash"

Returns:

{
  "file": 1234,
  "pos": 567890,
  "undo_file": 1234,
  "undo_pos": 123456
}

getblockfileinfo​

Get information about block files:

bitcoin-cli getblockfileinfo 1234

Wallet Commands​

sweepprivkeys​

Sweep the funds controlled by one or more private keys into the loaded wallet. Takes a single options object (there is no destination parameter — funds go to a new address in your wallet) and returns the sweep transaction id:

bitcoin-cli -rpcwallet=mywallet sweepprivkeys '{"privkeys": ["<WIF key>"], "label": "swept"}'

See Sweep Private Keys for details.

dumpmasterprivkey​

Export the HD master private key (legacy wallets):

bitcoin-cli -rpcwallet=legacy dumpmasterprivkey
Security Warning

Never share your master private key. This gives complete control over your wallet.

Fee Commands​

savefeeestimates​

Save fee estimates to disk:

bitcoin-cli savefeeestimates

Network Commands​

getrpcwhitelist​

Get RPC whitelisting information:

bitcoin-cli getrpcwhitelist

getgeneralinfo​

Get general node information (combines multiple info commands):

bitcoin-cli getgeneralinfo

Utility Commands​

getaddressinfo (Enhanced)​

Enhanced with transaction ID information:

bitcoin-cli getaddressinfo "address"

Includes a use_txids field listing the ids of wallet transactions which received with the address.
