# Fill A Limit Order

## Limit order execution

1. KyberSwap users can place a Limit Order through the interface at [KyberSwap](https://kyberswap.com/limit/) with no gas fee
2. Anyone can fetch these off-chain signed orders using Limit Order API to perform trade by filling the order on-chain
3. To fill the order, the taker can call the `fillOrder`, `fillOrderTo`, `fillBatchOrderTo` or `fillOrderToWithPermit` function on the Smart Contract.

The encoding API can be used to make it easier. In the case of `fillBatchOrderTo`, KyberSwap's encoding API even returns encodeData so that better orders will be filled first.
