@kyvejs/sdk is a JavaScript library for interacting with the Kyve network blockchain.

Installation

npm

npm install @kyvejs/sdk

yarn

yarn add @kyvejs/sdk

Usage example

    const sdk = new KyveSDK('korellia');
    const client = await sdk.fromMnemonic(mnemonic);
    const transferTx= await client.kyve.base.v1beta1.transfer('kyve1qcual...', '1000000000');
    const receipt = await transferTxPromise.execute()

Configuring an sdk

Instantiate the sdk with the network name. network name can be one of the following:

• korellia
• alpha
• beta
• local

    const sdk = new KyveSDK('korellia');

Sdk instance can be configured with a network object.

    const network = {
        rpc: "https://rpc.korellia.kyve.network",
        rest: "https://api.korellia.kyve.network",
        chainId: "korellia-2",
        chainName: "Korellia",
   }
    const sdk = new KyveSDK(network);

Initiate client

To initiate a transaction, you need to create a client instance.

    const sdk = new KyveSDK('korellia');
    const client = await sdk.fromMnemonic(mnemonic);

Client instance can be created from a mnemonic or a private key.

    const clientMnenonic = await sdk.fromMnemonic(mnemonic);
    const clientPrivateKey = await sdk.fromPrivateKey(privateKey);

For frontend applications, you can use the following method to create a client instance.

@kyve/sdk has native supports for following cosmos wallets:

• Keplr
• Cosmostation

    const keplrClient = await sdk.fromKeplr();
    const cosmostationClient = await sdk.fromCosmostation();

Transactions

Kyve transactions

All kyve transactions can be accessible with kyve property

    const transferTx = await client.kyve.base.v1beta1.transfer('kyve1qcual...', '1000000000');

We are highly recommend to use typescript for better intellisense and type safety.

Pending transactions

Each transaction returns a pending transaction. It's a not executed transaction. It's helpful because you can get the transaction hash before executed.

    const transferTxPending = await client.kyve.base.v1beta1.transfer('kyve1qcual...', '1000000000');
    transferTxPending.txHash // returns transaction hash
    const receipt = await transferTxPending.execute();

Cosmos transactions

@kyve/sdk is a wrapper around Cosmjs, you can access Cosmjs SigningStargateClient instance with nativeClient property.

    const tx = await client.nativeClient.signAndBroadcast(
      wallet.address,
      [msg],
      fee,
      memo
    );

Transactions All

Each transaction returns an incomplete transaction. It gives the ability to execute several messages in one transaction

const multiTransferTxSignedPending = await sdkInstance.kyve.base.v1beta1.multiTransfer([
        'kyve1qcual...',
        'kyve1pfs...'
    ], '1000000000');
    const transferTxSignedPending = await sdkInstance.kyve.base.v1beta1.transfer('kyve1qcua....', '1000000000');
    // combine several messages to one
    const txsAllResultSignedPending = await sdkInstance.kyve.base.v1beta1.txsAll([multiTransferTxSignedPending, transferTxSignedPending]);
    const receipt = await txsAllResultPromise.execute();

You can use txsAll with unsigned pending transactions too.

    const transferTxUnsignedPending1 = sdkInstance.kyve.base.v1beta1.transfer('kyve1qcua....', '1000000000');
    // when you call `await` the transaction will be signed by sdk.
    const transferTxSignedPending2 = await sdkInstance.kyve.base.v1beta1.transfer('kyve1qcua....', '1000000000');
    const txsAllResultSignedPending = await sdkInstance.kyve.base.v1beta1.txsAll([transferTxUnsignedPending1, transferTxSignedPending2]);
    const receipt = await txsAllResultPromise.execute();

Any transaction can be added to the txsAll method. Also, you can pass to txsAll result of another txsAll method.

    const txsAllResultPromise = await sdkInstance.kyve.base.v1beta1.txsAll([await sdkInstance.kyve.base.v1beta1.txsAll([trx1, trx2]), transferTxPending]);
    const receipt = await txsAllResultPromise.execute();

The approach is same like you work with JavaScript Promise object and Promise.all method.

Queries

To interact with the Kyve blockchain rest api, you can use lcdClient.

    const query = await sdk.createLCDClient();
    const pools = query.kyve.query.v1beta1.pools();

We are highly recommend to use typescript for better intellisense and type safety.
