Usage

RPC Clients

import { sgenetwork } from 'sgejs';

const { createRPCQueryClient } = sgenetwork.ClientFactory; 
const client = await createRPCQueryClient({ rpcEndpoint: RPC_ENDPOINT });

// now you can query the cosmos modules
const balance = await client.cosmos.bank.v1beta1
    .allBalances({ address: 'sge1addresshere' });

// you can also query the sge modules
const balances = await client.sge.market
    .market({ uid: '2d55a893-163f-41a7-b71f-837912b7b1e9' })

Composing Messages

Import the sge object from sge.

import { sgenetwork } from 'sgejs';

const {
    betsByUIDs, /** Queries a list of Bet items filtered by uid list. */
    betsByCreator, /** Queries list of Bet items of a certain creator sorted by timestamp. */
    pendingBets /** Queries list of pending Bet items. */
} = sge.bet;

Cosmos Messages

import { cosmos } from 'sgejs';

const {
    fundCommunityPool,
    withdrawDelegatorReward,
    withdrawValidatorCommission
} = cosmos.distribution.v1beta1.MessageComposer.fromPartial;

const {
    beginRedelegate,
    delegate,
    undelegate
} = cosmos.staking.v1beta1.MessageComposer.fromPartial;

const {
    deposit,
} = cosmos.gov.v1beta1.MessageComposer.fromPartial;

Connecting with Wallets and Signing Messages

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

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

Creating Signers

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

• cosmos-kit (recommended)
• keplr
• cosmjs

Proto Signer

import { getOfflineSignerProto as getOfflineSigner } from 'cosmjs-utils';

WARNING: NOT RECOMMENDED TO USE PLAIN-TEXT MNEMONICS. Please take care of your security and use best practices such as AES encryption and/or methods from 12factor applications.

import { chains } from 'chain-registry';

const mnemonic =
  'unfold client turtle either pilot stock floor glow toward bullet car science';
  const chain = chains.find(({ chain_name }) => chain_name === 'sge-network');
  const signer = await getOfflineSigner({
    mnemonic,
    chain
  });

Broadcasting Messages

Now that you have your stargateClient, you can broadcast messages:

const { send } = cosmos.bank.v1beta1.MessageComposer.withTypeUrl;

const msg = send({
    amount: [
    {
        denom: 'coin',
        amount: '1000'
    }
    ],
    toAddress: address,
    fromAddress: address
});

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