Example code snippets to query the chain for bank module related data.

Using gRPC

• Get bank module params

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcBankApi = new ChainGrpcBankApi(endpoints.grpc);

const moduleParams = await chainGrpcBankApi.fetchModuleParams();

console.log(moduleParams);

• Fetching injective address's balances

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcBankApi = new ChainGrpcBankApi(endpoints.grpc);

const injectiveAddress = "inj...";

const balances = await chainGrpcBankApi.fetchBalances(injectiveAddress);

console.log(balances);

• Fetching cosmos address' balances per base denom

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcBankApi = new ChainGrpcBankApi(endpoints.grpc);

const injectiveAddress = "inj1"; /* example is using Cosmos Hub */
const denom = "inj";

const balance = await chainGrpcBankApi.fetchBalance({
  accountAddress: injectiveAddress,
  denom,
});

console.log(balance);

• Fetching total supply on chain

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s)
const chainGrpcBankApi = new ChainGrpcBankApi(endpoints.grpc)

const pagination = {...} as PaginationOption

const totalSupply = await chainGrpcBankApi.fetchTotalSupply(
  pagination /* optional pagination parameter */
)

console.log(totalSupply)

Using HTTP REST

• Fetching address's balances

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainRestBankApi = new ChainRestBankApi(endpoints.rest);

const injectiveAddress = "inj...";

const balances = await chainGrpcBankApi.fetchBalances(injectiveAddress);

console.log(balances);

• Fetching cosmos address' balances per base denom

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainRestBankApi = new ChainRestBankApi(endpoints.rest);

const cosmosAddress = "cosmos..."; /* example is using Cosmos Hub */
const denom = "uatom";

const balance = await chainGrpcBankApi.fetchBalance(cosmosAddress, denom);

console.log(balance);
