Wasm

チェーン上のwasmモジュールをクエリするためのコードスニペット例。

​

gRPCを使用する

​

contractのアカウント残高を取得する。追加のアカウントを取得するためにpaginationパラメータを渡すこともできます。

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

const endpoints = getNetworkEndpoints(Network.Testnet)
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)

​

contractに関連する情報を取得する

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

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

const contractAddress = "inj...";

const contractInfo = await chainGrpcWasmApi.fetchContractInfo(contractAddress);

console.log(contractInfo);

​

contractのhistoryを取得する

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

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

const contractAddress = "inj...";

const contractHistory = await chainGrpcWasmApi.fetchContractHistory(
  contractAddress
);

console.log(contractHistory);

​

smart contractのstateを取得する

import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcWasmApi, toBase64 } from "@injectivelabs/sdk-ts/client/chain";

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

const contractAddress = "inj...";
const query = "...";
const queryFromObject = toBase64({ get_coin: {} });

const contractState = await chainGrpcWasmApi.fetchSmartContractState({
  contractAddress,
  query /* optional string query - HAS to be in base64 or use queryFromObject */,
});

console.log(contractState);

​

smart contractのraw stateを取得する

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

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

const contractAddress = "inj...";
const query = "...";
const queryFromObject = toBase64({ get_coin: {} });

const rawContractState = await chainGrpcWasmApi.fetchRawContractState({
  contractAddress,
  query /* optional string query - HAS to be in base64 or use queryFromObject */,
});

console.log(rawContractState);

​

contractに紐づくcodesを取得する

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

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

const pagination = {...} as PaginationOption


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

console.log(rawContractState)

​

contract codeに紐づく情報を取得する

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

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

const codeId = 1;

const codeDetails = await chainGrpcWasmApi.fetchContractCode(codeId);

console.log(codeDetails);

​

codeに紐づくcontractsを取得する

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

const endpoints = getNetworkEndpoints(Network.Testnet)
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)
