HyperCore Precompiles

Melt contracts interact with HyperCore through precompile addresses — native system contracts on HyperEVM.

The asset bridge prefix is 0x2000000000000000000000000000000000000000 — each HIP-1 token’s bridge address is computed by adding the core index to this prefix.

​
Asset Bridge

Each HIP-1 token has a dedicated asset bridge address computed from its core index: 
function getAssetBridge(uint64 coreIndexId) internal pure returns (address) {
    return address(uint160(ASSET_BRIDGE_PREFIX) + coreIndexId);
}
The asset bridge is the gateway between HyperEVM and HyperCore spot balances.

​
Spot Transfer

To send tokens from HyperEVM to a user’s HyperCore spot balance: 
HyperCoreLib.sendSpotTransfer(recipient, coreIndexId, amount);
This encodes a SPOT_SEND action and calls the ICoreWriter precompile.

​
HyperLiquid Info API

The web app uses the HyperLiquid Info API for real-time market data:
  • Market tickers — price, volume, 24h change
  • Order book — real-time bid/ask depth
  • Candle data — OHLCV for charting
  • Recent trades — latest executed trades
  • User state — positions, open orders, balances

​
WebSocket Integration

Real-time data streams via WebSocket for:
  • Order book updates
  • Trade execution notifications
  • Balance changes
