# Swap routing — multi-hop best-price paths on Fogo

> How Vulcx routing works on Fogo: direct, multi-hop (up to 5 hops), and split routes across Vortex, Fluxbeam, Fogo.fun, and Moonit, with slippage protection.

# Routing

Vulcx evaluates multiple paths to find the best execution for every swap.

## Direct swaps

For common pairs with deep liquidity (e.g., FOGO/USDC), a single pool often provides the best price. Vulcx compares rates across all supported pools and picks the one with the lowest price impact.

## Multi-hop routing

When a direct swap isn't optimal, Vulcx routes through intermediate tokens. For example, swapping Token A → Token B might execute as:

```
Token A → FOGO → USDC → Token B
```

Each hop uses the best available pool. The routing engine evaluates all viable paths and selects the one that maximizes output (ExactIn) or minimizes input (ExactOut).

The routing engine supports up to **5 hops** on Fogo.

## Supported liquidity sources

| Source   | Type                   |
| -------- | ---------------------- |
| Vortex   | Concentrated liquidity |
| Fluxbeam | AMM                    |
| Fogo.fun | Bonding curves         |
| Moonit   | Bonding curves         |

## Price impact

Every quote includes price impact data:

| Severity   | Range     | Meaning                                          |
| ---------- | --------- | ------------------------------------------------ |
| `none`     | \< 0.1%   | Negligible                                       |
| `low`      | 0.1% – 1% | Normal for most trades                           |
| `moderate` | 1% – 3%   | Consider splitting into smaller trades           |
| `high`     | 3% – 5%   | Significant. Review before proceeding.           |
| `extreme`  | > 5%      | Very large trade relative to available liquidity |

## Slippage protection

The `slippageBps` parameter sets the maximum acceptable price deviation. If the on-chain execution price is worse than the threshold, the transaction reverts atomically. No partial fills.
