You can just add its configuration into file base58prefix.txt. Format is:

Symbol, Coin name, Address prefix, Address base58 version (prefix), Private key base58 version (prefix)

You need to know the ‘address base58 version’ and ‘private key base58 version’.

tnks!

@bobkasho Have you found ‘address base58 version’ and ‘private key base58 version’ for Mooncoin?
It should be 3 and 131 respectively, refer: https://github.com/mooncoincore/wallet/blob/master/src/chainparams.cpp#L122

unfortunately I don't quite understand this question :(

@bobkasho I have commit the code, help me to verify it. Here is an example:

$ ./vanitygen++ -C MOON 2abcd

MOON Pattern: 2abcd

https://chainz.cryptoid.info/moon/address.dws?2abcdz7jEQUXNxFhqoqNX4duPw8LUkR2G8.htm

The coin also has a prefix "M" - it is more modern. "2" is already deprecated

I am not very familiar with Mooncoin.

MOON Privkey: 5Pv7zZZisUyCrAEW87c42iebZvQmeunqQ1ZsShJS3vEBEFAVAR9

The value -X 50 -Y 131 comes from https://github.com/mooncoincore/wallet/blob/master/src/chainparams.cpp#L124

You can customize prefix MMMM, please don't send too much coin to the generated address before you verified. All coins may be lost forever. Use as your own risk.

but what is correct for Windows?
that's how it works for me :

"C:\vangen152>vanitygen.exe -C MOON -F script -X 50 -Y 131 Moon
Prefix 'Moon' not possible
Hint: Run vanitygen with "-C LIST" for a list of valid prefixes. Also note that many coin
s only allow certain characters as the second character in the prefix.

C:\vangen152>"

@bobkasho Have you see any Mooncoin address starts with 'Moon' ? May be it's impossible, you can try another prefix:

$ ./vanitygen++ -C MOON -F script -X 50 -Y 131 MMoon
Generating MOON Address

@bobkasho There is no vanitygen.exe in this project, only vanitygen++.exe. How did you get this program?

@10gic please link

I don't use Windows. You can build it by yourself, or download a prebuilt https://github.com/10gic/vanitygen-plusplus/releases/download/v0.1.0/prebuilt.win32.v0.1.0.zip

As file base58prefix.txt is not shipped in package, you can't use -C MOON, it don't matter, just ignore it:
vanitygen++.exe -F script -X 50 -Y 131 Mmoon

@10gic
COOL!

dont cool :(
"C:\vangen>oclvanitygen++.exe -F script -X 50 -131 MMMMM

@10gic
and why the second character of the prefix must necessarily be "M" - addresses come with one "M" at the beginning.
example: MTGTA72cSCwUJNu1TuQzkGBvoqpft2HLSV

@bobkasho The second character doesn't required be "M", it's just an example. You can use another prefix:

./vanitygen++ -F script -X 50 -Y 131 MTG
Difficulty: 1353
Pattern: MTG
P2SH Address: MTGWPq2EVdNojrVFmXRuJ5koo3MNBmCr3A

Again, I am not familiar with Mooncoin, use as your own risk. You need verify the generated private key.

Currently, -F script is not implemented for oclvanitygen++.exe.

Many people report that oclvanitygen++.exe doesn't work in Windows. Could you help me check if oclvanitygen++.exe works for legacy mooncoin address? Just run:

oclvanitygen++.exe -X 3 -Y 131  2abcd

See what happens?

It seems calc_addrs.cl is missing. Could you download file https://raw.githubusercontent.com/10gic/vanitygen-plusplus/master/calc_addrs.cl into the same directory of oclvanitygen++.exe, and run it again?

@10gic
crash ))

Thanks for share the result.

This is not good news. Currently, I don't have a windows device, and I don't have time to fix this problem. Suggest you use vanitygen++.exe in Windows, or try oclvanitygen++ in CentOS.

The fix of this issue is welcome.

@10gic
The address is not displayed in the wallet :( after import

There are two common types of P2SH address: MULTISIG and segwit address.

The -F script would generate P2SH (MULTISIG, but in case 1-of-1 ), refer:

Very likely, the "M" address in Mooncoin is the segwit address. If so, you would not get the matched address after import private key.

I will check it later.

@bobkasho Could you help me confirm that the following information matches?

Private key: 5PiUadgWDWjGcVHCKctSq1RiCRY1Y2CCKZrX8PgaJTwKUBeYnKs
Address: MRkY26CMfAbLGB1niZRfML3XX1Ca5ZoWBo

OK! I started importing. it will take up to one hour

@10gic
the address is not displayed in the wallet after import

@bobkasho I see a button "Generate native segwit (Bech32) address" in GUI, is the "M" address a native segwit (Bech32) address?

BTW, what's the address derived from private key: 5PiUadgWDWjGcVHCKctSq1RiCRY1Y2CCKZrX8PgaJTwKUBeYnKs ?

I can't find the technical doc about Mooncoin address derivation. The BTC address derivation is very clear: https://en.bitcoin.it/wiki/Invoice_address. I want to find similar technical doc for Mooncoin. Please share me if you known this.

I will clarify

@10gic
More than likely there isn't a specific document saying the same thing
Mooncoin addresses are generated at time of send/receive/request by the wallet itself.
