lightning-funderupdate -- Command for adjusting node funding v2 channels ======================================================================== SYNOPSIS -------- **funderupdate** [*policy*] [*policy\_mod*] [*leases\_only*] [*min\_their\_funding\_msat*] [*max\_their\_funding\_msat*] [*per\_channel\_min\_msat*] [*per\_channel\_max\_msat*] [*reserve\_tank\_msat*] [*fuzz\_percent*] [*fund\_probability*] [*lease\_fee\_base\_msat*] [*lease\_fee\_basis*] [*funding\_weight*] [*channel\_fee\_max\_base\_msat*] [*channel\_fee\_max\_proportional\_thousandths*] [*compact\_lease*] NOTE: Must have --experimental-dual-fund enabled for these settings to take effect. DESCRIPTION ----------- For channel open requests using *policy*, *policy\_mod* is the policy the funder plugin will use to decide how much capital to commit to a v2 open channel request. There are three policy options, detailed below: `match`, `available`, and `fixed`. The *policy\_mod* is the number or 'modification' to apply to the policy. Default is (fixed, 0sats). * `match` -- Contribute *policy\_mod* percent of their requested funds. Valid *policy\_mod* values are 0 to 200. If this is a channel lease request, we match based on their requested funds. If it is not a channel lease request (and *lease\_only* is false), then we match their funding amount. Note: any lease match less than 100 will likely fail, as clients will not accept a lease less than their request. * `available` -- Contribute *policy\_mod* percent of our available node wallet funds. Valid *policy\_mod* values are 0 to 100. * `fixed` -- Contributes a fixed *policy\_mod* sats to v2 channel open requests. Note: to maximize channel leases, best policy setting is (match, 100). *leases\_only* will only contribute funds to `option_will_fund` requests which pay to lease funds. Defaults to false, will fund any v2 open request using *policy* even if it's they're not seeking to lease funds. Note that `option_will_fund` commits funds for 4032 blocks (~1mo). Must also set *lease\_fee\_base\_msat*, *lease\_fee\_basis*, *funding\_weight*, *channel\_fee\_max\_base\_msat*, and *channel\_fee\_max\_proportional\_thousandths* to advertise available channel leases. *min\_their\_funding\_msat* is the minimum funding sats that we require in order to activate our contribution policy to the v2 open. Defaults to 10k sats. *max\_their\_funding\_msat* is the maximum funding sats that we will consider to activate our contribution policy to the v2 open. Any channel open above this will not be funded. Defaults to no max (`UINT_MAX`). *per\_channel\_min\_msat* is the minimum amount that we will contribute to a channel open. Defaults to 10k sats. *per\_channel\_max\_msat* is the maximum amount that we will contribute to a channel open. Defaults to no max (`UINT_MAX`). *reserve\_tank\_msat* is the amount of sats to leave available in the node wallet. Defaults to zero sats. *fuzz\_percent* is a percentage to fuzz the resulting contribution amount by. Valid values are 0 to 100. Note that turning this on with (match, 100) policy will randomly fail `option_will_fund` leases, as most clients expect an exact or greater match of their `requested_funds`. Defaults to 0% (no fuzz). *fund\_probability* is the percent of v2 channel open requests to apply our policy to. Valid values are integers from 0 (fund 0% of all open requests) to 100 (fund every request). Useful for randomizing opens that receive funds. Defaults to 100. Setting any of the next 5 options will activate channel leases for this node, and advertise these values via the lightning gossip network. If any one is set, the other values will be the default. *lease\_fee\_base\_msat* is the flat fee for a channel lease. Node will receive this much extra added to their channel balance, paid by the opening node. Defaults to 2k sats. Note that the minimum is 1sat. *lease\_fee\_basis* is a basis fee that's calculated as 1/10k of the total requested funds the peer is asking for. Node will receive the total of *lease\_fee\_basis* times requested funds / 10k satoshis added to their channel balance, paid by the opening node. Default is 0.65% (65 basis points) *funding\_weight* is used to calculate the fee the peer will compensate your node for its contributing inputs to the funding transaction. The total fee is calculated as the `open_channel2`.`funding_feerate_perkw` times this *funding\_weight* divided by 1000. Node will have this funding fee added to their channel balance, paid by the opening node. Default is 2 inputs + 1 P2WPKH output. *channel\_fee\_max\_base\_msat* is a commitment to a maximum `channel_fee_base_msat` that your node will charge for routing payments over this leased channel during the lease duration. Default is 5k sats. *channel\_fee\_max\_proportional\_thousandths* is a commitment to a maximum `channel_fee_proportional_millionths` that your node will charge for routing payments over this leased channel during the lease duration. Note that it's denominated in 'thousandths'. A setting of `1` is equal to 1k ppm; `5` is 5k ppm, etc. Default is 100 (100k ppm). *compact\_lease* is a compact description of the channel lease params. When opening a channel, passed in to `fundchannel` to indicate the terms we expect from the peer.
