Example code snippets to query the chain’s staking module

​
Using gRPC

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const moduleParams = await chainGrpcStakingApi.fetchModuleParams();

console.log(moduleParams);

​
Fetch unbonded and bonded tokens for a pool

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const pool = await chainGrpcStakingApi.fetchPool();

console.log(pool);

​
Fetch validators and associated metadata

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const validators = await chainGrpcStakingApi.fetchValidators();

console.log(validators);

​
Fetch validator and associated metadata from a validator address

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

const validatorAddress = "injvaloper...";

const validator = await chainGrpcStakingApi.fetchValidator(validatorAddress);

console.log(validator);

​
Fetch delegations associated with a validator

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

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const delegations = await chainGrpcStakingApi.fetchValidatorDelegationsNoThrow({
  validatorAddress,
  pagination /* optional pagination options */
})

console.log(delegations)

​
Fetch unbonding delegations associated with a validator

import { getNetworkEndpoints, Network } from '@injectivelabs/networks'

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const unbondingDelegations = await chainGrpcStakingApi.fetchValidatorUnbondingDelegationsNoThrow({
  validatorAddress,
  pagination /* optional pagination options */
})

console.log(unbondingDelegations)

​
Fetch delegations associated with an injective address for a specific validator

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc);

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

const delegation = await chainGrpcStakingApi.fetchDelegation({
  injectiveAddress,
  validatorAddress,
});

console.log(delegation);

​
Fetch delegations for an injective address

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

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

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

const delegations = await chainGrpcStakingApi.fetchDelegationsNoThrow({
  injectiveAddress,
  pagination /* optional pagination options */
})

console.log(delegations)

​
Fetch delegators for a validator

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

const chainGrpcStakingApi = new ChainGrpcStakingApi(endpoints.grpc)

const validatorAddress = 'injvaloper...'
const pagination = {...} as PaginationOption

const delegators = await chainGrpcStakingApi.fetchDelegatorsNoThrow({
  validatorAddress,
  pagination /* optional pagination options */
})

console.log(delegators)

​
Fetch unbonding delegations for an injective address

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