<p>While experimenting with Lightning Network, I decided to put as little on the wallet as possible. This created problems when creating my own channel - it looks like some nodes have minimum amounts required to open a channel. <a href="https://mempool.space" rel="nofollow noreferrer">mempool.space</a> doesn't display this information. Is there a way to know it up-front other than just trying to create it?</p>

Can I know in advance the minimum amount required by a node to open a channel?

While experimenting with Lightning Network, I decided to put as little on the wallet as possible. This created problems when creating my own channel - it looks like some nodes have minimum amounts required to open a channel. [mempool.space](https://mempool.space) doesn't display this information. Is there a way to know it up-front other than just trying to create it?

The BOLT documents say that its not mandatory to broadcast a minimum channel price, each node do as he want for that, the best way to get this information is to do it by trial and error, try to open a channel with a specific amount and usually they will answer something like `insufficient channel size` when this amount is not enough.
