Address format

The same two branches as Bitcoin, with Litecoin's constants, and a third that Bitcoin doesn't have.

Legacy L… is version 0x30 and M… is 0x32, 25 Base58Check bytes each with the checksum verified. The deprecated 3… form under 0x05 isn't accepted: those bytes are, byte for byte, a Bitcoin script address, and a validator that says yes to both isn't telling you anything.

SegWit ltc1… runs the BIP-173 and BIP-350 check under the ltc prefix: Bech32 for v0, Bech32m for v1 and up, program length, padding, checksum. A mistyped ltc1 address fails the way a mistyped bc1 one does.

MWEB ltcmweb1… is the stealth address of the MimbleWimble extension block. It's plain Bech32 and runs past BIP-173's 90 characters to 121, so the check reads it the way Litecoin Core does: the checksum, a version digit of 0, and 66 bytes behind it, the scan key and the spend key. The keys aren't checked as curve points. The testnet tmweb1… form is rejected.

import { getChain } from "@agntn/chains";

const chain = getChain("ltc");
chain.assertAddress("ltc1qhdhvrwe6rgqns8fz28tee0hphr5x7ulw5exv4w"); // returned unchanged
chain.type; // "utxo"
chain.caip2; // "bip122:12a765e31ffd4059bada1e25190f6e98"
