Is there a brain wallet with lightning network support? https://www.bitaddress.org/ seems has NO lightning network support.

I want to generate bitcoin address and private key with lightning network support. Exchange withdraw fees are too high for ordinary address.

Thank you very much!

I think you have misunderstood how LN (lightning) works.

Let's start from what a brainwallet is. A brainwallet is an unsafe way to generate a private key, by hashing a phrase that you generate on your brain.

So for example, the phrase franklin2058 will generate the following:
Private key (hex): 1c97d6a461f857e2cd864d39426def7e4724d6c77e630696b589a2f139bf4b26
Private key (WIF): KxBHu7A2YggFc4kpq5aW52d8uHNyzvWPG6ADRtAR2855P2ruxdYQ
Addresses: 1QJcNn9PAPCLNeJnESou9h6QVNPnmGSKJD / 3GfLUQJTgNY7gqm1EPBX2MQdQ9SXACkbse / bc1ql70harvmavj8ru293ckcy3hgaevdteawc9gcdq

Essentially you will only need to remember the phrase franklin2058 and you will be able to recover the wallet.

I will not explain how insecure these wallets are in this post, since it is irrelevant, but I definetely encourage you not to use them.

Now, LN is a layer that sits on top of Bitcoin's blockchain. It works by creating channels between nodes and then those nodes can exchange sats without paying insane fees. Once the channels are closed, then an on-chain transaction happens on the blockchain that settles the amounts to the addresses.

Having said that, there are mainly 2 implementations of LN nodes:
1. LND
2. CLN

Essentially, you generate an on-chain deposit address. This address will be in the bech32 format and can be used to send Bitcoin funds to your LND wallet. From this address you will be able to fund the channels.

These 2 implementations don't support brainwallets! So, the funding address is properly generated, collecting entropy from various sources. The address is part of Hierarchical Deterministic wallet.

If what you want is a good LN wallet, then I suggest you totally forget brainwallets. Brain is not suitable for secure implementations! Just follow the proper way that everyone uses and you will be just fine.

Finally, some more wallet suggestions:
1. If you run your own LN node:

For PC: Ride the Lightning, SPARK, LNBits
For Mobile: Zeus

1. If you DON'T run your own LN node:

For PC: *I haven't used any so I can't suggest*
For Mobile: Wallet of Satoshi (custodial), Muun (semi-custodial), Phoenix (non-custodial)
