Exchange

查询链上 exchange 模块的示例代码片段。

​

使用 gRPC

​

获取参数，如默认现货和衍生品费用/交易奖励

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const moduleParams = await chainGrpcExchangeApi.fetchModuleParams();

console.log(moduleParams);

​

获取费用折扣计划

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const feeDiscountSchedule =
  await chainGrpcExchangeApi.fetchFeeDiscountSchedule();

console.log(feeDiscountSchedule);

​

获取与 injective 地址关联的费用折扣

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const injectiveAddress = "inj...";

const feeDiscountAccountInfo =
  await chainGrpcExchangeApi.fetchFeeDiscountAccountInfo(injectiveAddress);

console.log(feeDiscountAccountInfo);

​

获取交易奖励活动详情，如总奖励积分

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const tradingRewardsCampaign =
  await chainGrpcExchangeApi.fetchTradingRewardsCampaign();

console.log(tradingRewardsCampaign);

​

获取 injective 地址的交易奖励积分

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const injectiveAddress = "inj...";

const tradeRewardsPoints = await chainGrpcExchangeApi.fetchTradeRewardsPoints(
  injectiveAddress
);

console.log(tradeRewardsPoints);

​

获取 injective 地址的待处理交易奖励积分

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const injectiveAddresses = ["inj..."];

const pendingTradeRewardsPoints =
  await chainGrpcExchangeApi.fetchPendingTradeRewardPoints(injectiveAddresses);

console.log(pendingTradeRewardsPoints);

​

获取当前仓位，如 subaccountId、marketId 和 position

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

// 替换为您自己的 Injective 地址
const injectiveAddresses = ["inj1..."];

const positions = await chainGrpcExchangeApi.fetchPositions(injectiveAddresses);

console.log(positions);

​

获取子账户交易 nonce

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcExchangeApi } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const subaccountId = "0x...";

const subaccountTradeNonce =
  await chainGrpcExchangeApi.fetchSubaccountTradeNonce(subaccountId);

console.log(subaccountTradeNonce);
