Auth - Injective Docs

Example code snippets to query the auth module on the chain.

Using gRPC

Fetch parameters such as max memo characters or tsx signature limit

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcAuthApi = new ChainGrpcAuthApi(endpoints.grpc);

const moduleParams = await chainGrpcAuthApi.fetchModuleParams();

console.log(moduleParams);

Fetch account details associated with an injective address such as the account’s address, sequence, or pub_key

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcAuthApi = new ChainGrpcAuthApi(endpoints.grpc);
const injectiveAddress = "inj...";

const accountDetailsResponse = await chainGrpcAuthApi.fetchAccount(
  injectiveAddress
);

console.log(accountDetailsResponse);

Fetch list of accounts on chain

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

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcAuthApi = new ChainGrpcAuthApi(endpoints.grpc)
const injectiveAddress = 'inj...'
const pagination = {...} as PaginationOption

const accounts = await chainGrpcAuthApi.fetchAccounts(/* optional pagination params*/)

console.log(accounts)

Using HTTP REST

Fetch account details associated with an injective address such as the account’s address, sequence, or pub_key

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainRestAuthApi = new ChainRestAuthApi(endpoints.rest);
const injectiveAddress = "inj...";

const accountDetailsResponse = await chainRestAuthApi.fetchAccount(
  injectiveAddress
);

console.log(accountDetailsResponse);

Fetch cosmos address from an injective address

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

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainRestAuthApi = new ChainRestAuthApi(endpoints.rest);
const injectiveAddress = "inj...";

const cosmosAddress = await chainRestAuthApi.fetchCosmosAccount(
  injectiveAddress
);

console.log(cosmosAddress);
