I need help with the sendcoins command

[arthur-feral]

Hello,

I have a lnd node with a default wallet configured and unlocked.

I want to send some sats on-chain and for that I am using the sendcoins command.

The problem is that the output amount calculated seems to include a crazy amount of fees:

[/lnrpc.Lightning/SendCoins]: insufficient input to create sweep tx: input_sum=0.00341786 BTC, output_sum=7.47600000 BTC

I am struggling to understand why.

Do you have any idea if this comes from a misconfiguration of the node?

Thanks for your help!

Hi @arthur-feral, thanks for starting this discussion.

If you try to send a certain amount to an address and would like to control the fee rate your command could look something like this:
lncli sendcoins --addr <dest_addr> --amt <amt_to_send> --sat_per_vbyte <sat/vbyte>

This shouldn't come from a misconfiguration of your node. Are you trying to send more funds than you have available in your wallet?
What is the command you are using?

Hello, Thanks for your answer.

so the output of

lncli listchannels

{
    "channels":  []
}

lncli pendingchannels

is

lncli pendingchannels
{
    "total_limbo_balance":  "0",
    "pending_open_channels":  [],
    "pending_closing_channels":  [],
    "pending_force_closing_channels":  [],
    "waiting_close_channels":  []
}

lncli walletbalance

{
    "total_balance":  "341786",
    "confirmed_balance":  "341786",
    "unconfirmed_balance":  "0",
    "locked_balance":  "0",
    "reserved_balance_anchor_chan":  "0",
    "account_balance":  {
        "default":  {
            "confirmed_balance":  "341786",
            "unconfirmed_balance":  "0"
        }
    }
}

now if I do this:

lncli sendcoins --addr xxx --amt 10000 --sat_per_vbyte 50

I get

[lncli] rpc error: code = Unknown desc = manual fee rate input of 12500 sat/kw is too low to be accepted into the mempool or relayed to the network

What would you suggest?

[hieblmi]

Is your intent to sweep all confirmed funds to an address? Could you try it with sat_per_vbyte instead of conf_target?

[arthur-feral]

The command returning the error with the crazy fees is

lncli sendcoins --sweepall --conf_target 800 bc1xxx

[hieblmi]

The result of this seems really off, probably due to your local mempool size and the current fee environment.

@hieblmi Thanks for your answers and help.
Eventually, I've asked chatgpt what was wrong, gave some context and quoted your answer, and it gave me a fix for the bitcoind config. All good, it works normally now.

[hieblmi]

Nice that you could resolve it. May I ask what the suggested fix is that works?

[arthur-feral]

the value for minrelaytxfee was incorrect and changing it to something like 0.00001 fixed my issue
