- Requires Go 1.16
- Run the following command:
$ go build
- The dust tool can intercept malicious
open_channelrequests with highdust_limit_satoshisvalues. - Simply run it like so:
./dust-tool -network=<mainnet/testnet/etc> -macpath=<path-of-macaroon> -host=<host:port of RPC server>
- You should see output like this:
2021/09/30 18:06:47 Creating dust acceptor, no output will be recorded unless it errors out.
- The dust tool can also give channel close recommendations based on a confirmed channel's
dust_limit_satoshisandmax_accepted_htlcsvalues. - Simply run it like so, optionally specifying
-dustexposurein satoshis:
./dust-tool -network=<mainnet/testnet/etc> -macpath=<path-of-macaroon> -host=<host:port of RPC server> -check-chans -dustexposure=1000000
- If a potentially risky channel is found, you should receive output like this:
2021/09/30 18:12:59 Evaluating set of channels for dust exposure
2021/09/30 18:12:59 Consider closing chanpoint(e2b43845a099c7ab98345a4604b24d7fbb4c19cec97911a9c1c250b57c762220:0), dust exposure(0.0483 BTC) higher than threshold(0.0049 BTC)
- If no output is returned, you are safe for the dust threshold specified!
Usage of ./dust-tool:
-check-chans
whether to check existing channels for dust_limit_satoshis exposure
-dustexposure uint
sets the dust threshold in satoshis for channel close recommendations - must be specified with checkchans (default 600000)
-host string
host of the target lnd node (default "localhost:10009")
-macpath string
path of admin.macaroon for the target lnd node (default "/path/admin.macaroon")
-network string
the network the lnd node is running on (default "mainnet")
-tlspath string
path to the TLS cert of the target lnd node (default "/path/tls.cert")
