litecoin constants and prefixes

Question

Is there any list of litecoin constants available? Something like Bitcoin list of address prefixes

Answer 1

Here is what I've gathered so far regarding the different version bytes for each type of Litecoin public address:

Mainnet:

• p2pkh L-address (LM2WMpR1Rp6j3Sa59cMXMs1SPzj9eXpGc1): 0x30
• p2sh deprecated 3-address (3MSvaVbVFFLML86rt5eqgA9SvW23upaXdY): 0x05 (same as bitcoin's mainnet p2sh)
• p2sh new M-address (MTf4tP1TCNBn8dNkyxeBVoPrFCcVzxJvvh): 0x32
• native segwit bech32 address (ltc1q8c6fshw2dlwun7ekn9qwf37cu2rn755u9ym7p0): prefix ltc, version 1

Testnet:

• p2pkh m- or n-address (mipcBbFg9gMiCh81Kj8tqqdgoZub1ZJRfn): 0x6f (same as bitcoin's testnet p2pkh)
• p2sh deprecated 2-address (2N2PJEucf6QY2kNFuJ4chQEBoyZWszRQE16): 0xc4
• p2sh new Q-address (QVk4MvUu7Wb7tZ1wvAeiUvdF7wxhvpyLLK): 0x3a
• native segwit bech32 address (tltc1qyw3c0rvn6kk2c688y3dygvckn57525y8emy4p5): prefix tltc, version 1

This is the Litecoin project's converter between old and new p2sh address format. And this is an online base58check decoder to check the version byte.

Answer 2

L - Legacy, Non-P2SH (Pay to script hash) address prefix

3 - P2SH prefix that's backwards compatible to the M prefix. When I say backwards compatible, I mean that there is a 3 address and an M address that point to the same address (Reference: https://blog.trezor.io/litecoins-new-p2sh-segwit-addresses-843633e3e707)

M - Current P2SH address prefix

Litecoin WIF Prefixes: 6 (0x36) and 7 (0x37)
