I would be happy to help you convert your channel IDs from C-Lightning to LND. Here is a step-by-step guide on how to do it:

Understanding Channel IDs

For both C-Lightning and LND, channel IDs are used to identify and manage payment channels between users. The ID format is usually as follows:

Channel ID (height, block number, location number, transaction hash)

For example, a common channel ID for C-Lightning might be 505580x1917x1.

Converting C-Lightning to LND

To convert a C-Lightning channel ID to an LND-compatible format, you need to perform the following steps:

Step 1: Parse the C-Lightning channel ID

First, parse the C-Lightning channel ID string into its components:

height (x): 505580
block number (x): 1917
slot number (x): 1
transaction hash (x): ?

Note that we are focusing on the “height”, “block number” and “location” fields in the LND.

Step 2: Convert to LND-compatible format

To convert the parsed values ​​to LND-compatible format, use the following formula:

channel_id = (height  60) + (block_number  10^15) + location

Here’s how the formula breaks down:

“(height 60)” calculates the total number of units in the channel by multiplying the “height” field by 60.

(block_number 10^15) converts the block number to LND-compatible format, where each block consists of 10^15 units. This is done by shifting the block number 15 bits to the left (i.e. dividing by 1000000) and then multiplying by 10^15.

Step 3: Calculate the Channel ID

Now that we have the parsed values ​​and the conversion formula, let’s calculate the LND-compatible Channel ID:

Channel ID = (505580  60) + (1917  10^15) + location

Calculate the Channel ID using the formula above.

Step 4: Add a unique ID

To make the Channel ID more readable and useful, add a unique ID to each channel. You can do this by appending a suffix to the channel ID:

channel_id = "LND Channel ID: "

For example, if our channel ID is “505580x1917x1”, we would append the character “x” to get the value “505580x1917x2”.

Example use case

Let’s say you have a C-Lightning channel with the following values:

height (x): 506000
block number (x): 1928
slot number (x): 2
transaction hash (x): ?

Using the above formula, we can calculate the LND-compatible channel ID as follows:

channel_id = (506000  60) + (1928  10^15) + 2

The result would be 31168000 for our example channel.

If you follow these steps, you should have an LND-compatible channel ID for your C-Lightning channels.
