# Swap across EVM & Solana

> Bridge and swap assets between EVM chains and Solana using Socket

Socket supports swapping assets from any EVM chain to Solana and from Solana to any EVM chain.

This guide walks you through swapping assets between EVM chains and Solana using Socket, including supported chains, transaction options, and current limitations.

## Quick Start

### Solana Chain ID

The **chain ID** for Solana queries is `89999`.

### Key differences

Here's what's different when integrating Solana compared to standard EVM chains:

**Transaction Flow**

* No token approvals are needed on Solana

**API Behavior**

* Both `userAddress` and `receiverAddress` required for quotes
* Fee collection only works from EVM to Solana

<Accordion title="Special Token Address Handling">
  - **Native Tokens across all Chains (`0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee`):** Use this address to represent native tokens on any chain (ETH, SOL, etc.)
  - **Wrapped SOL (wSOL) (`So11111111111111111111111111111111111111112`):** The SPL token address for wrapped SOL on Solana
</Accordion>

## Integration Steps

1. **Select Chains:** Users choose the source and destination chains, which determine the tokens available for bridging.
2. **Fetch Quote:** Call the `/quote` endpoint which returns an `autoRoute` object containing `txData`, `requestHash`, and optionally `approvalData`.
3. **Handle Token Approval (EVM only):** For EVM transactions, check if `approvalData` exists. Solana transactions do not require approvals.
4. **Submit Transaction:** Execute the transaction using `txData` from the quote response.
5. **Track Transaction Status:** Poll the `/status` endpoint using the source `txHash` until the bridging process is complete.

<Info>
  For Solana quotes, please ensure both `userAddress` and `receiverAddress` are defined.

  Solana does not require token approvals.
