Usage

RPC Clients

import { getAllBalances } from "injectivejs/cosmos/bank/v1beta1/query.rpc.func";
import { getExchangeBalances } from "injectivejs/injective/exchange/v1beta1/query.rpc.func";

{ getRpcEndpoint } = useChain("injective");

const endpoint = await getRpcEndpoint();

// now you can query the cosmos modules
const balance = await getAllBalances(endpoint, {
  address: "inj1addresshere",
});

const exchangeBalance = await getExchangeBalances(endpoint, {});

Tx Helpers

For tx messages, there're helper functions to sign and broadcast messages:

For more detailed usage on how to use these functions, please see the starship tests in the networks/injective repo

There're also react and vue hooks for helper functions. Please see injective-react and injective-vue repos for more information.

Connecting with Wallets and Signing Messages

⚡️ For web interfaces, we recommend using interchain-kit. Continue below to see how to manually construct signers and clients.

Here are the docs on creating signers in interchain-kit that can be used with Keplr and other wallets.

Initializing the Signing Client

Use SigningClient.connectWithSigner and pass in the signer options for injective to get your SigningClient:

import { SigningClient } from "@interchainjs/cosmos/signing-client";
import { defaultSignerOptions } from "@interchainjs/injective/defaults";

const signingClient = await SigningClient.connectWithSigner(
  await getRpcEndpoint(),
  new AminoGenericOfflineSigner(aminoOfflineSigner),
  {
    signerOptions: defaultSignerOptions.Cosmos,
  }
);

Creating Signers

To broadcast messages, you can create signers with a variety of options:

• interchain-kit (recommended)
• keplr
• cosmjs

Broadcasting Messages

When you have your signing client, you can broadcast messages:

const msg = {
  typeUrl: MsgSend.typeUrl,
  value: MsgSend.fromPartial({
    amount: [
      {
        denom: "inj",
        amount: "1000",
      },
    ],
    toAddress: address,
    fromAddress: address,
  }),
};

const fee: StdFee = {
  amount: [
    {
      denom: "inj",
      amount: "864",
    },
  ],
  gas: "86364",
};
const response = await signingClient.signAndBroadcast(address, [msg], fee);

All In One Example

For a comprehensive example of how to use InjectiveJS to send messages, please see the example here. This example demonstrates how to:

• Initialize the client.
• Create and sign messages.
• Broadcast transactions.
• Handle responses and errors.

The example provides a complete walkthrough of setting up the client, creating a message for sending tokens, and broadcasting the transaction to the Injective blockchain.

Follow the instructions in the example to set up your InjectiveJS client and start sending messages to the Injective blockchain.

Advanced Usage

If you want to manually construct a signing client, you can do so by following the example below:

import {
    cosmosAminoConverters,
    cosmosProtoRegistry,
    cosmwasmAminoConverters,
    cosmwasmProtoRegistry,
    ibcProtoRegistry,
    ibcAminoConverters,
    injectiveAminoConverters,
    injectiveProtoRegistry
} from 'injectivejs';

const signer: OfflineSigner = /* create your signer (see above)  */
const rpcEndpoint = 'https://rpc.cosmos.directory/injective'; // or another URL

const protoRegistry: ReadonlyArray<[string, GeneratedType]> = [
    ...cosmosProtoRegistry,
    ...cosmwasmProtoRegistry,
    ...ibcProtoRegistry,
    ...injectiveProtoRegistry
];

const aminoConverters = {
    ...cosmosAminoConverters,
    ...cosmwasmAminoConverters,
    ...ibcAminoConverters,
    ...injectiveAminoConverters
};

const registry = new Registry(protoRegistry);
const aminoTypes = new AminoTypes(aminoConverters);

const signingClient = await SigningClient.connectWithSigner(rpcEndpoint, signer);

signingClient.addEncoders(registry);
signingClient.addConverters(aminoTypes);

Developing

When first cloning the repo:

yarn
yarn build:dev

Codegen

Contract schemas live in ./contracts, and protos in ./proto. Look inside of scripts/inj.telescope.json and configure the settings for bundling your SDK and contracts into injectivejs:

yarn codegen

Publishing

Build the types and then publish:

yarn build
yarn publish
