# Rune

Source: https://developers.bitgo.com/docs/rune

## Overview

Rune (thorchain:rune) is the native asset of the THORChain blockchain. It utilizes:

- Account model
- EcDSA signature algorithm

THORChain is a decentralized cross-chain liquidity protocol that utilizes the Tendermint consensus engine, Cosmos-SDK state machine, and GG20 Threshold Signature Scheme (TSS). It operates as an independent Layer 1 cross-chain decentralized exchange (DEX) built on the Cosmos SDK. It could be described as a "cross-chain automated market maker (AMM), like Uniswap" or a "decentralized Binance".

## Wallets Types

BitGo enables holding Rune in the following wallet types:

|                  | Multisig Cold | Multisig Hot | MPC Cold | MPC Hot |
| :--------------- | :------------ | :----------- | :------- | :------ |
| **Custodial**    | ❌             | ❌            | ✅        | ✅       |
| **Self Managed** | ❌             | ❌            | ✅        | ✅       |

## Ticker Symbols

| Mainnet        | Testnet         |
| :------------- | :-------------- |
| thorchain:rune | tthorchain:rune |

## Faucet

THORChain does not have a faucet to obtain testnet Rune for development and testing purposes.

## Units

Rune is divisible by 10<sup>-8</sup> and the base unit is a tor:

- 1 Rune = 100,000,000 tor
- 1 tor = 0.00000001 Rune

Rune balances can be in either integer or string format. However, BitGo recommends using string format to ensure values don't exceed the programmable number limit.

## Tokens

The THORChain blockchain doesn't natively support tokens.

## Fees

Rune has the following fees:

- Minimum fee = 0.02 Rune
- Default fee rate = 0.02 Rune

}'
```
```js JavaScript
const { BitGo } = require('bitgo');

const accessToken = '<YOUR_ACCESS_TOKEN>';

// Initialize the SDK
const bitgo = new BitGo({

env: 'test',
});

// Generate hot wallet
async function createHotWalletSimple() {
const newWallet = await bitgo.coin('tthorchain:rune').wallets().generateWallet({
    label: '<DESIRED_WALLET_NAME>',
    passphrase: '<YOUR_BITGO_LOGIN_PASSWORD>',
});

console.log(JSON.stringify(newWallet, undefined, 2));
}
```

## Create Address

```shell cURL
