About
合约允许用户下限价订单，稍后可以在链上完成。 限价订单本身是一种在链下创建并根据 EIP-712 签名的数据结构。
您很可能需要使用以下类：
LimitOrderBuilder - 创建限价订单
LimitOrderPredicateBuilder - 创建谓词限价订单
LimitOrderProtocolFacade - 与区块链上
的协议 该协议的主要特点是通过使用以下订单类型实现的极大灵活性和高气体效率。
I. Limit order
限价订单是一种金融工具，您可以使用它以固定价格出售 ERC-20 代币。
例如，您可以以 82415 DAI 代币的价格出售 2 个 WBTC 代币。
1inch limit orders protocol 有许多灵活的交易管理工具：
- Partial fill
- Predicates
- Single cancellation
- Bunch cancellation
- Fullness check
- Validation
注意：即使您的余额不足以立即执行限价订单，您也可以创建限价订单。 但是，您必须为制造商资产留出余地。
对于做市，有RFQ订单经过特殊优化，执行时不需要大量gas。
Limit orders in the 1inch aggregation protocol
1inch aggregation protocol - 该协议从各种交易所获取流动性，并能够拆分单个贸易交易跨多个 DEX，以确保最佳费率。
您可以将您的限价订单发送到1inch 数据库，然后您的订单将参与1inch 聚合协议。

II. RFQ order
报价请求 (RFQ) 是客户向供应商（做市商）请求报价以购买某些代币的业务流程。
从技术上讲，RFQ 订单是标准订单的精简版，它包含更少的数据和管理工具，从而可以显着减少执行费用。

About
Contract allows users to place limit orders, that later could be filled on-chain. Limit order itself is a data structure created off-chain and signed according to EIP-712.
Most probably you would need use following classes:
LimitOrderBuilder - to create a limit order
LimitOrderPredicateBuilder - to create a predicate for limit order
LimitOrderProtocolFacade - to interact with the protocol on the blockchain
Key features of the protocol is extreme flexibility and high gas efficiency that achieved by using following order types.
I. Limit order
A limit order is a financial instrument with which you can put up an ERC-20 token for sale at a fixed price.
For example, you can put up for sale 2 WBTC tokens at the price of 82415 DAI tokens.
1inch limit orders protocol has many tools for flexible trade management:
- Partial fill
- Predicates
- Single cancellation
- Bunch cancellation
- Fullness check
- Validation
Note: You can create a limit order even if your balance is insufficient to execute the limit order right now. However you must have an allowance for the maker asset.
For market making, there are RFQ orders that have special optimization that does not require a large amount of gas for execution.
Limit orders in the 1inch aggregation protocol
1inch aggregation protocol - the protocol sources liquidity from various exchanges and is capable of splitting a single trade transaction across multiple DEXes to ensure the best rates.
You can send your limit orders to the 1inch database and then your order will participate in the 1inch aggregation protocol.

II. RFQ order
A request for quotation (RFQ) is a business process in which a customer requests a quote from a supplier (market maker) for the purchase of some tokens.
Technically, RFQ orders are a stripped-down version of standard orders, which contains less data and tools to manage, which in turn allows to spend significantly less gas for their execution.
