Top-level config which holds ChannelHandshakeLimits and ChannelConfig.

Default::default() provides sane defaults for most configurations (but currently with 0 relay fees!)

Fields

channel_handshake_config: ChannelHandshakeConfig

Channel handshake config that we propose to our counterparty.

channel_handshake_limits: ChannelHandshakeLimits

Limits applied to our counterparty’s proposed channel handshake config settings.

channel_config: ChannelConfig

Channel config which affects behavior during channel lifetime.

accept_forwards_to_priv_channels: bool

If this is set to false, we will reject any HTLCs which were to be forwarded over private channels. This prevents us from taking on HTLC-forwarding risk when we intend to run as a node which is not online reliably.

For nodes which are not online reliably, you should set all channels to not be announced (using ChannelHandshakeConfig::announced_channel and ChannelHandshakeLimits::force_announced_channel_preference) and set this to false to ensure you are not exposed to any forwarding risk.

Note that because you cannot change a channel’s announced state after creation, there is no way to disable forwarding on public channels retroactively. Thus, in order to change a node from a publicly-announced forwarding node to a private non-forwarding node you must close all your channels and open new ones. For privacy, you should also change your node_id (swapping all private and public key material for new ones) at that time.

Default value: false.

accept_inbound_channels: bool

If this is set to false, we do not accept inbound requests to open a new channel. Default value: true.

manually_accept_inbound_channels: bool

If this is set to true, the user needs to manually accept inbound requests to open a new channel.

When set to true, Event::OpenChannelRequest will be triggered once a request to open a new inbound channel is received through a msgs::OpenChannel message. In that case, a msgs::AcceptChannel message will not be sent back to the counterparty node unless the user explicitly chooses to accept the request.

Default value: false.

accept_intercept_htlcs: bool

If this is set to true, LDK will intercept HTLCs that are attempting to be forwarded over fake short channel ids generated via ChannelManager::get_intercept_scid. Upon HTLC intercept, LDK will generate an Event::HTLCIntercepted which MUST be handled by the user.

Setting this to true may break backwards compatibility with LDK versions < 0.0.113.

Default value: false.

accept_mpp_keysend: bool

If this is set to false, when receiving a keysend payment we’ll fail it if it has multiple parts. If this is set to true, we’ll accept the payment.

Setting this to true will break backwards compatibility upon downgrading to an LDK version < 0.0.116 while receiving an MPP keysend. If we have already received an MPP keysend, downgrading will cause us to fail to deserialize ChannelManager.

Default value: false.
