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

​
Using gRPC

​
Fetch 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.Testnet)
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc)

const moduleParams = await chainGrpcExchangeApi.fetchModuleParams()

console.log(moduleParams)

​
Fetch the fee discount schedules

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

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

const feeDiscountSchedule =
  await chainGrpcExchangeApi.fetchFeeDiscountSchedule()

console.log(feeDiscountSchedule)

​
Fetch the fee discounts associated with an injective address

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

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

const injectiveAddress = 'inj...'

const feeDiscountAccountInfo =
  await chainGrpcExchangeApi.fetchFeeDiscountAccountInfo(injectiveAddress)

console.log(feeDiscountAccountInfo)

​
Fetch the details regarding the trading reward campaign, such as the total reward points

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

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

const tradingRewardsCampaign =
  await chainGrpcExchangeApi.fetchTradingRewardsCampaign()

console.log(tradingRewardsCampaign)

​
Fetch the trading rewards points for an injective address

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

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

const injectiveAddress = 'inj...'

const tradeRewardsPoints = await chainGrpcExchangeApi.fetchTradeRewardsPoints(
  injectiveAddress,
)

console.log(tradeRewardsPoints)

​
Fetch the pending trading rewards points for injective addresses

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

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

const injectiveAddresses = ['inj...']

const pendingTradeRewardsPoints =
  await chainGrpcExchangeApi.fetchPendingTradeRewardPoints(injectiveAddresses)

console.log(pendingTradeRewardsPoints)

​
Fetch 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.Testnet)
const chainGrpcExchangeApi = new ChainGrpcExchangeApi(endpoints.grpc)

const positions = await chainGrpcExchangeApi.fetchPositions(injectiveAddresses)

console.log(positions)

​
Fetch the subaccount trade nonce

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

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

const subaccountId = '0x...'

const subaccountTradeNonce =
  await chainGrpcExchangeApi.fetchSubaccountTradeNonce(subaccountId)

console.log(subaccountTradeNonce)
