The 1inch Solana Fusion SDK enables token swaps on Solana with ultra-fast transactions and minimal fees. Unlike EVM chains where orders are signed off-chain, Solana orders are placed directly on-chain through escrow contracts.

## Key Benefits

- **Ultra-Fast Transactions** - Solana's ~400ms block times mean near-instant order confirmation
- **Minimal Fees** - Transaction costs are typically under $0.01, with no additional 1inch fees
- **Deep Liquidity** - Access swaps across over 1 million Solana-native tokens
- **MEV Protection** - Built-in protection against front-running and sandwich attacks

## How Solana Fusion Works

The swap process on Solana differs from EVM chains:

1. **Create Order** - The SDK generates a FusionOrder with optimal auction parameters
2. **Build Escrow Transaction** - A transaction is prepared to create an on-chain escrow holding your tokens
3. **Sign and Broadcast** - You sign and submit the transaction (paying ~$0.001 in fees)
4. **Resolver Fills Order** - Resolvers compete to fill your order at the best price
5. **Receive Tokens** - The destination token is delivered directly to your wallet

## Core Methods

- **getQuote** - Fetches current pricing and auction parameters. Use this to display expected output amounts before users commit to a trade.
- **createOrder** - Generates a FusionOrder struct with source/destination tokens, amounts, and Dutch auction parameters. This data is used to build the on-chain escrow transaction.
- **getOrderStatus** - Checks whether an order is still active or has been filled/cancelled. Use this for polling-based status tracking.
- **WebSocketApi** - Real-time order status updates as an alternative to polling. Subscribe to order events for instant notifications when your order is filled or cancelled.

## Integration Pattern

A typical integration follows this flow:

1. **Initialize SDK** - Create an SDK instance with your API key
2. **Fetch Quote** - Show users the expected swap rate before they confirm
3. **Create Order** - Generate the order structure when user approves
4. **Build Transaction** - Use FusionSwapContract to create the escrow instruction
5. **Submit & Track** - Broadcast the transaction and monitor for completion
