# Overview

LiquidCore uses Hyperliquid precompiles for pricing data, enabling an oracle-validated AMM on HyperEVM.

## What the pools provide

LiquidCore pools offer deep, liquid markets for stablecoin–WHYPE pairs (USDT0/WHYPE, USDC/WHYPE, USDH/WHYPE). For **traders**, they deliver predictable execution and tight spreads via oracle-backed pricing. For **aggregators**, they provide a single integration surface: a REST quote API and the **LiquidCore Router** for execution.

**Executing swaps:** Use the **LiquidCore Router** (`0x625aC1D165c776121A52ff158e76e3544B4a0b8B`). It discovers the correct pool for any supported pair—approve the router for `tokenIn` and call `swap(tokenIn, tokenOut, amountIn, minAmountOut)`. When new pools are added, the router is updated so integrators don't need to track pool addresses. The quote API returns this router as `executionAddress`.

## Pricing and fees

* Use the quote API or `estimateSwap` before execution to get current expected output.
* Always set `minAmountOut` for slippage protection.

## Referral support

Pools and the router support referral-aware swaps via:

`swap(tokenIn, tokenOut, amountIn, minAmountOut, refCode)`

Referral allocation applies only for allowlisted `refCode` values. For full referral integration details, see [Referrals](https://docs.liqd.ag/liquidcore-integration/referrals).
