## **What are THORNames?**

**THORNames** (TNS), aka THORChain vanity addresses allow anyone to register cross-chain wallet addresses to a 1-30 long string of hexadecimal characters which include special characters `-_+`. THORNames are **case insensitive**.

**THORNames** simplify and humanise THORChain wallet addresses to optimize cross-chain compatibility. In short, it is a domain naming system for your wallet based on the **THORChain** blockchain. This will vastly simplify managing your wallet addresses across multiple blockchains.

A THORChain address can be assigned one (1) THORName to manage the other associated addresses for supported L1 Chains.

For example, Chad registers Chad.THOR and assigns it to their THORChain address, using our [dedicated interface](https://app.thorswap.finance/thorname), they can then assign a wallet address to each supported L1 chain.

```
{"chad" :
  {"thor : "thor1egxvam70a86jafa3s0m2g3m7548gcg3kqfmfax",
   "btc" : "bc1qq2z2f4gs4nd7t0a9zzjtegu4nczhajjp90y9l9",
   "eth" : "0x04c5998ded94f8926e64a99b7dbc9f463370444c",
   "bch" : "qz7262r7uufxk89emajqm97vskzwtxrf6yquk7zfwr",
   "ltc" : "ltc1qaa064vvv4d6stgrd3tt93fp6jxywnf777j6dl8",
   "bnb" : "bnb1pa6hpjs7qv0vkd55n08yw7v7fks5tqa2xtt2gk"
   "doge" : "DNUfRBroVNhu53QXRG9vtB7t8vxwji3iG6"}
}
```

When using THORSwap, Chad can choose to send and receive correct native assets to their correct wallet addresses. Supported Wallet providers will easily be able to integrate to resolve cross-chain addresses for Chad.

Currently, there are six (6) native L1 chains available on THORChain: Bitcoin, Ethereum, Litecoin, Binance, Bitcoin Cash, Doge. THORNames are limited to 30 characters, including all characters `a-Z`, all numbers `0–9` and special characters `-_+` .

## More info:

{% hint style="info" %}
**THORName Fees**<br>

There is a one-time registration fee of around 10 RUNE, with a 20 `tor` block fee, which works out to be around 1 RUNE annually. A user who pays 2 RUNE will then keep their name registered for 2 years.&#x20;

Example: 20 Rune registers the THORName for 10 years. \
(10 RUNE Registration Fee + 1 RUNE every year).
{% endhint %}

{% hint style="info" %}
**What else does THORNames enable?**

\
UTXO chains such as Bitcoin has a memo length limitation of 80 bytes and Monero has an address length of 97 bytes. This means swapping from Bitcoin to Monero is not possible using addresses, THORNames solves this issue and allows the potential integration of more chains such as Monero/ Haven to THORSwap in the future.
{% endhint %}

{% hint style="info" %}
**Renewing THORNames**

**THORNames** will expire when the registration fee paid runs out, this is a fixed amount per year. You can register for 1 day or for 100 years, completely up to you.\
\
(The exact date is based on THORChain block numbers, not real world days - check estimate on: [app.thorswap.finance/thorname](https://app.thorswap.finance/thorname))
