KyberSwap Limit Order API Demo

This repository serves as a guide for developers looking to interact with KyberSwap Limit Order via a typescript environment. For simplicity, the examples are implemented purely in Node.js so that users can focus on the backend logic required to achieve the following Limit Order operations:

• General APIs
  • Get Chain Supported Pairs (getSupportedPairs())
  • Get Limit Order Contract Addresses (getContracts())
• Maker APIs
  • Get Unsigned Create Order Message (postCreateOrderUnsigned())
  • Create New Order (postCreateOrder())
  • Get List Of Orders By maker (getMakerOrders())
  • Get Maker Active Making Amount (getMakerActiveAmount())
  • Get Unsigned Cancel Order(s) Message (postCancelOrderUnsigned())
  • Submit Gasless Cancel Order(s) (postCancelOrder())
  • Generate Encoded Data For Batch Cancellation (postCancelBatchOrders())
  • Generate Encoded Data For Cancel All (postCancelAllOrders())
• Taker APIs
  • Get Orders By Token Pair (getOrders())
  • Request Operator Signature For Maker Orders (getOperatorSignature())
  • Generate Encoded Data To Fill Order (postFillOrder())
  • Generate Encoded Data To Fill Batch Order (postFillBatchOrders())

To aid with readability, each operation has its own .ts file which has been categorized under the /src/operations/ folder. Users can run specific operations by commenting or uncommenting the relevant function in index.ts.
