# Dash

> Base58Check under 0x4c and 0x10, 25 bytes, no Bech32. Its own genesis, so unlike the Bitcoin forks it gets a CAIP-2 reference.

<chain-facts chain="dash">



</chain-facts>

## Address format

Base58Check only. `X…` is version `0x4c`, `7…` is `0x10`, 25 bytes either way with the checksum verified. That's the whole of Dash Core's `DecodeDestination`: it tries base58, checks the two prefixes, and gives up. Dash never took SegWit, so there's no Bech32 branch to check.

Testnet moves both bytes, `0x8c` writes `y…` and `0x13` writes `8…`, and both fail here. No other chain in the registry uses `0x4c` or `0x10`, so [identify](https://chains.agntn.dev/guide/identify) names Dash alone for a mainnet address.

The chain started from its own genesis block in 2014, not from a Bitcoin fork. So the CAIP-2 reference is plain BIP-122: the first 32 hex digits of the genesis hash that `chainparams.cpp` asserts.

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

const chain = getChain("dash");
chain.assertAddress("XjszN1jZJthEoaQDhGthRkaHL9AqaG3Vzw"); // returned unchanged
chain.bip44; // 5
chain.caip2; // "bip122:00000ffd590b1485b3caadc19b22e637"
```

## Spellings

`dash`, `Dash`. The key is the ticker too, so there's no alias to learn.
