⚠️ The Docs have been moved to https://docs.ts.injective.network/querying/querying-chain/querying-chain-exchange ⚠️

Example code snippets to query the exchange module on the chain.

Using gRPC

• Get parameters such as the default spot and derivatives fees/trading rewards

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const moduleParams = await chainGrpcExchangeApi.fetchModuleParams();

console.log(moduleParams);

• Get the fee discounts schedule

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const feeDiscountSchedule =
  await chainGrpcExchangeApi.fetchFeeDiscountSchedule();

console.log(feeDiscountSchedule);

• Get the fee discounts associated with an injective address

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const injectiveAddress = "inj...";

const feeDiscountAccountInfo =
  await chainGrpcExchangeApi.fetchFeeDiscountAccountInfo(injectiveAddress);

console.log(feeDiscountAccountInfo);

• Get the details regarding the trading reward campaign, such as the total rewards points

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const tradingRewardsCampaign =
  await chainGrpcExchangeApi.fetchTradingRewardsCampaign();

console.log(tradingRewardsCampaign);

• Get the trading rewards points for an injective address

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const injectiveAddress = "inj...";

const tradeRewardsPoints = await chainGrpcExchangeApi.fetchTradeRewardsPoints(
  injectiveAddress
);

console.log(tradeRewardsPoints);

• Get the pending trading rewards points for injective addresses

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

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

const pendingTradeRewardsPoints =
  await chainGrpcExchangeApi.fetchPendingTradeRewardPoints(injectiveAddresses);

console.log(pendingTradeRewardsPoints);

• Get the current positions, such as subaccountId, marketId, and position

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const positions = await chainGrpcExchangeApi.fetchPositions(injectiveAddresses);

console.log(positions);

• Get the subaccount trade nonce

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc);

const subaccountId = "0x...";

const subaccountTradeNonce =
  await chainGrpcExchangeApi.fetchSubaccountTradeNonce(subaccountId);

console.log(subaccountTradeNonce);
