@kiichain/kiijs-evm

install

npm install @kiichain/kiijs-proto

Usage

You can utilize the types to build and send messages. To query, you can utilize an RPC query client, while for transactions you will need a wallet client paired with composing a message and then broadcasting it.

RPC Clients

To create an RPC client you can import the following helper and utilize it:

import { kiichain } from '@kiichain/kiijs-proto';

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

// now you can query the cosmos modules
const balance = await client.cosmos.bank.v1beta1
    .balance({ address: 'kiichain1addresshere', denom: 'akii' });

Explore the types to find out what types of queries are available and how to utilized them.

Composing Messages

To compose messages, you can utilize the message composer of the respective type you want to build. For instance, tokenfactory messages can be found like this:

import { kiichain } from '@kiichain/kiijs-proto';

const {
    createDenom,
    mint,
    burn,
    changeAdmin,
    setDenomMetadata,
    forceTransfer,
    updateParams
} = kiichain.tokenfactory.v1beta1.MessageComposer.withTypeUrl;

We have a small section with a few more examples.

Cosmos Messages

import { cosmos } from '@kiichain/kiijs-proto';

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

const {
    multiSend,
    send
} = cosmos.bank.v1beta1.MessageComposer.fromPartial;

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

const {
    deposit,
    submitProposal,
    vote,
    voteWeighted
} = 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.

Initializing the Stargate Client

Use getSigningKiiChainClient to get your SigningStargateClient, with the proto/amino messages full-loaded. No need to manually add amino types, just require and initialize the client:

import { getSigningKiiChainClient } from '@kiichain/kiijs-proto';

const stargateClient = await getSigningKiiChainClient({
  rpcEndpoint,
  signer // OfflineSigner
});

Creating Signers

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

• cosmos-kit (recommended)
• keplr
• cosmjs

Amino Signer

Likely you'll want to use the Amino, so unless you need proto, you should use this one:

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

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 === 'kiichain');
  const signer = await getOfflineSigner({
    mnemonic,
    chain
  });

Broadcasting Messages

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

import { cosmos } from '@kiichain/kiijs-proto'

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

const msg = send({
    amount: [
    {
        denom: 'akii',
        amount: '10000000000000000'
    }
    ],
    toAddress: address,
    fromAddress: address
});

const fee: StdFee = {
    amount: [
    {
        denom: 'akii',
        amount: '10000000000000000'
    }
    ],
    gas: '86364'
};
const response = await stargateClient.signAndBroadcast(address, [msg], fee);

Converting from Hex to Bech32 and vice-versa

We have a few helper functions for converting Hex to Bech32 and vice versa on the @kiichain/kiijs-evm. We did not import them over here since the proto files are all generated.

import { HexToBech32, Bech32ToHex } from '@kiichain/kiijs-evm'

const kiiAddress = HexToBech32("0xyourhex")

const evmAddress = Bech32ToHex("kiiYouraddress)

Advanced Usage

If you want to manually construct a stargate client

import { OfflineSigner, GeneratedType, Registry } from "@cosmjs/proto-signing";
import { AminoTypes, SigningStargateClient } from "@cosmjs/stargate";

import { 
    cosmosAminoConverters,
    cosmosProtoRegistry,
    cosmwasmAminoConverters,
    cosmwasmProtoRegistry,
    ibcProtoRegistry,
    ibcAminoConverters,
    kiichainAminoConverters,
    kiichainProtoRegistry
} from '@kiichain/kiijs-proto';

const signer: OfflineSigner = /* create your signer (see above)  */
const rpcEndpoint = 'https://rpc.dos.sentry.testnet.v3.kiivalidator.com/'; // or another URL

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

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

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

const stargateClient = await SigningStargateClient.connectWithSigner(rpcEndpoint, signer, {
    registry,
    aminoTypes
});
