# Cross-Chain Swap

Swap converts any token into any other token across **13 supported chains** — same-chain or cross-chain, in one transaction flow, with automatic best-price routing. It trades straight from your wallet: no order book, no product balance to fund, full self-custody.

***

## Supported chains

**Solana · Ethereum · Base · Arbitrum · Optimism · Polygon · BNB · Linea · Scroll · Gnosis · Berachain · Robinhood · Arc**

Swap both within and between them — Solana ↔ EVM included. On most EVM chains **gas is sponsored**, so you can trade without holding the native token; on Solana, Ethereum, and BNB keep a small native-token balance for gas.

## How routing works

You never pick a route — the terminal does:

- **Solana ↔ Solana** swaps route through **Carbium**, onchain.cc's Solana routing engine, which splits your order across DEX liquidity for the best output. MEV protection is on by default.
- **Cross-chain and EVM** swaps route through **LiFi**, which finds the best bridge-and-swap path between chains.

The quote shows your expected output, price impact, and the route before you confirm — quotes refresh every 10 seconds while you decide.

## How to swap

1. **Pick your tokens** — the token you're paying with (and its chain) and the token you want (and its chain). Search by name or paste a contract address.

*Search by name, ticker, or contract address*

That's the whole flow. Sells work identically — flip the pair.

> **Note**

> Slippage protects you: if the price moves beyond your tolerance before the transaction lands, the trade reverts rather than filling at a worse price. The panel warns you when a setting or a quote looks risky (slippage above 3%, price impact above 10%).

## Swap vs. Spot

Swap is instant conversion from your wallet across 13 chains. [Spot](https://onchain.cc/docs/spot/overview.md) is order-book trading on Hyperliquid — limit orders, TWAPs, maker/taker fees — from a funded product balance. Converting tokens? Swap. Working orders on liquid pairs? Spot.

## Quick Swap on the Dashboard

The full swap panel is also available as the **Quick Swap** [Dashboard widget](https://onchain.cc/docs/portfolio-and-tools/dashboard.md) — same chains, same routing, same fees, embedded in your board.

> Every swap settles on-chain and is verifiable on the relevant chain's explorer from the confirmation screen. Completed swaps land in your wallet and appear in [Portfolio](https://onchain.cc/docs/portfolio-and-tools/portfolio-view.md).
