# USDH on HyperCore

> HIP-1 native token standard and quote asset features

## Overview

USDH on HyperCore is enabled via the HIP-1 native token standard. As an aligned quote asset, USDH contributes to the Hyperliquid protocol and provides enhanced functionality for trading and DeFi applications.

## Token Parameters

<ParamField path="Token Index" type="uint32">
  `360`
</ParamField>

<ParamField path="Token Address" type="hex">
  `0x54e00a5988577cb0b0c9ab0cb6ef7f4b`
</ParamField>

<ParamField path="System Address" type="address">
  `0x2000000000000000000000000000000000000168`
</ParamField>

<ParamField path="Deployer Address" type="address">
  `0x6b9891ed4bb1f034671f471667b1563bf7dc1327`
</ParamField>

<ParamField path="szDecimals" type="uint8">
  `2`
</ParamField>

<ParamField path="weiDecimals" type="uint8">
  `8`
</ParamField>

These parameters are standard across canonical stablecoin deployments on HyperCore, and compliance is enforced by the network as a prerequisite for quote asset status.

## Use Cases

### Spot Trading

USDH is available in spot balances for trading on multiple markets including **[USDH/USDC](https://app.hyperliquid.xyz/trade/USDH/USDC)** and **[HYPE/USDH](https://app.hyperliquid.xyz/trade/HYPE/USDH)**.

### Collateral for HIP-3 DEXes

USDH can be used as collateral for HIP-3 decentralized exchanges including [Felix](https://x.com/felixprotocol) and [Ventuals](https://x.com/ventuals).

### Permissionless Market Deployment

As an aligned quote asset, builders can permissionlessly deploy reduced-fee spot markets and HIP-3 DEX perp markets denominated in USDH via the token index, `360`.

## Account Initialization

As a quote asset, protocols can use USDH to pay the **\$1 HyperCore account initialization fee** when transferring the stablecoin to an uninitialized HyperCore address.

<Info>
  This enables seamless payments for end consumers without having to manage
  multiple stablecoin balances. Previously, all initialization fees were paid in
  USDC, irrespective of transferred assets.
</Info>

## Token Supply Architecture

At time of token deployment, USDH on HyperCore was initialized with a **100 billion token supply**, atomically transferred to the token system address at time of genesis. In this way, all token transfers between HyperEVM and HyperCore remain fully collateralized 1:1 across the networks, with shared token balances. This is a best-practice, recommended approach for canonical HyperEVM ↔ HyperCore bridging.

<Note>
  You can verify the initial supply transfer via the official [Hyperliquid
  explorer token info
  page](https://app.hyperliquid.xyz/explorer/token/0x54e00a5988577cb0b0c9ab0cb6ef7f4b).
</Note>

## Bridging Between Networks

Any transfers of the ERC-20 token on HyperEVM or the HIP-1 token on HyperCore to the system address will automatically reflect an according disbursement of USDH tokens on the counterpart network.
