Swaps integration

[rolznz]

Is there a way to integrate swaps into Alby Hub to make it easier for users?

• Savings -> Lightning channel with receiving capacity
• Lightning channel -> Savings
• Lightning channel -> External wallet
• External Onchain wallet -> Lightning channel with receiving capacity

Related: It's hard to swap from savings into a channel. This is actually impossible right now because we only have a redeem all function which is incompatible with boltz where you need to specify exact amounts

Other useful options would be

• Refill from other channels, which does a self payment from other channels of the node into the specified channel. Purpose: rebalance channels with internal funds
• Receive to channel: let's you specifically receive into this, and only this, channel. Purpose: channel top up from external wallet, or swap service
