0x Exchange Events

此存储库提供了一个库,可从部署在 graphprotocol 上的 0x 子图中查询 0x 交换事件。

不同于0x-event-extractor或通过getLogsAsync方法提取事件日志< a href="https://github.com/0xProject/0x-monorepo/tree/development/packages/0x.js">0x.js,这个客户端不需要服务器并且允许事件过滤超出索引事件参数(即 Fill 事件的 makerAddressfeeRecipientAddressorderHash)。

导入此模块并轻松筛选您需要的交换事件。

Install

yarn add 0x-exchange-events

Usage

您首先构建 HttpEventClient 的实例

import { HttpEventClient } from "0x-exchange-events";
const client = new HttpEventClient();

Get Fill Events

在 0x 协议的版本 2 上获取 50 个填充事件,由 makerAssetData 和 takerAssetData 过滤

const FillEvents = await client.getFillEventsAsync(50, {
  // Filter arguments
  makerAssetDataV2: "0xf47261b0000000000000000000000000e45b7cd82ac0f3f6cfc9ecd165b79d6f87ed2875",
  takerAssetDataV2: "0xf47261b0000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",
  ...
});

示例输出:

0x Exchange Events

This repository provides a library that queries 0x exchange events from a 0x subgraph deployed on graphprotocol.

Unlike the 0x-event-extractor or extracting event logs via the getLogsAsync method of 0x.js, this client does not require a server and allows event filtering beyond the indexed event arguments (i.e. makerAddress, feeRecipientAddress, orderHash for the Fill event).

Import this module and easily filter for the exchange event you need.

Install

yarn add 0x-exchange-events

Usage

You get started by constructing an instance of the HttpEventClient

import { HttpEventClient } from "0x-exchange-events";
const client = new HttpEventClient();

Get Fill Events

Get 50 fill events on version 2 of the 0x protocol, filtered by makerAssetData and takerAssetData

const FillEvents = await client.getFillEventsAsync(50, {
  // Filter arguments
  makerAssetDataV2: "0xf47261b0000000000000000000000000e45b7cd82ac0f3f6cfc9ecd165b79d6f87ed2875",
  takerAssetDataV2: "0xf47261b0000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",
