Distribution

チェーンからvalidatorへのdelegate関連データをクエリするためのコードスニペット例。

​

gRPCを使用する

​

base proposer rewardやbonus proposer rewardなどのパラメータを取得する

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const moduleParams = await chainGrpcDistributionApi.fetchModuleParams();

console.log(moduleParams);

​

特定のvalidatorへdelegateしているdelegatorの報酬の量とdenomを取得する

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const delegatorAddress = "inj...";
const validatorAddress = "injvaloper...";

const delegatorRewardsFromValidator =
  await chainGrpcDistributionApi.fetchDelegatorRewardsForValidatorNoThrow({
    delegatorAddress,
    validatorAddress,
  });

console.log(delegatorRewardsFromValidator);

​

delegatorのすべての報酬の量とdenomを取得する

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcDistributionApi = new ChainGrpcDistributionApi(endpoints.grpc);

const delegatorAddress = "inj...";

const totalDelegatorRewards =
  await chainGrpcDistributionApi.fetchDelegatorRewardsNoThrow(delegatorAddress);

console.log(totalDelegatorRewards);
