Example code snippets to query the wasm module on chain

Using gRPC

• Get a contacts' account balance Note that pagination parameters can be passed to obtain additional accounts.

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const contractAddress = 'inj...'
const pagination = {...} as PaginationOption

const contractAccountsBalance = await chainGrpcWasmApi.fetchContractAccountsBalance({
    contractAddress,
    pagination /* optional pagination options */
})

console.log(contractAccountsBalance)

• Get info related to a contract

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";

const contractInfo = await chainGrpcWasmApi.fetchContractInfo(contractAddress);

console.log(contractInfo);

• Get contract history

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";

const contractHistory = await chainGrpcWasmApi.fetchContractHistory(
  contractAddress
);

console.log(contractHistory);

• Get the state of a smart contract

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";
const query = "...";

const contractState = await chainGrpcWasmApi.fetchSmartContractState({
  contractAddress,
  query /* optional string query */,
});

console.log(contractState);

• Get the raw state of a smart contract

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";
const query = "...";

const rawContractState = await chainGrpcWasmApi.fetchRawContractState({
  contractAddress,
  query /* optional string query */,
});

console.log(rawContractState);

• Get the codes associated with a contract

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const pagination = {...} as PaginationOption


const rawContractState = await chainGrpcWasmApi.fetchRawContractState(
pagination /* optional pagination options */
)

console.log(rawContractState)

• Get info associated with a contract code

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const codeId = 1;

const codeDetails = await chainGrpcWasmApi.fetchContractCode(codeId);

console.log(codeDetails);

• Get the contracts associated with a code

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

const endpoints = getNetworkEndpoints(Network.TestnetK8s)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const codeId = 1
const pagination = {...} as PaginationOption

const contracts = await chainGrpcWasmApi.fetchContractCodeContracts({
  codeId,
  pagination /* optional pagination options */
})

console.log(contracts)
