Fusion orders on Solana have a defined lifecycle that includes filling by resolvers and cancellation options. Understanding this lifecycle helps you build robust applications that handle all possible order outcomes.

## Order Lifecycle

After an escrow is created on-chain, the order enters the active state where:

1. **Resolvers Monitor** - Professional market makers watch for profitable orders to fill
2. **Dutch Auction** - The offered price decreases over time, incentivizing quick fills
3. **Fill or Expire** - Either a resolver fills the order, or it expires after the deadline

## Cancellation Options

Orders can be cancelled in two scenarios:

- **Maker Cancellation** - As the order creator (maker), you can cancel your own order at any time before it's filled. This returns your tokens from the escrow back to your wallet.
- **Resolver Cancellation** - After an order expires, resolvers can trigger cancellation to clean up the escrow. For this service, resolvers earn a small cancellation premium (paid in lamports) as defined in the order parameters.
