@cere-ddc-sdk/blockchain

@cere-ddc-sdk/blockchain

The package provides API for interacting with Cere blockchain.

Installation

Using NPM:

npm install @cere-ddc-sdk/blockchain --save

Using yarn:

yarn add @cere-ddc-sdk/blockchain

Usage

The package provides Blockchain class which acts as an entry point and multiple DDC pallet wrappers, each of which is responsible for interacting with a particular DDC pallet on the blockchain.

Here is an example how to create a bucket

1. Create a Blockchain instance and connect it to TESTNET

   import { Blockchain, UriSigner } from '@cere-ddc-sdk/blockchain';
   
   const account = new UriSigner('//Alice');
   const blockchain = await Blockchain.connect({
     wsEndpoint: 'wss://rpc.testnet.cere.network/ws',
   });
   

2. Make a deposit

   const deposit = 100n * 10n ** blockchain.chainDecimals; // 100 CERE
   const tx = blockchain.ddcCustomers.deposit(deposit);
   
   await blockchain.send(tx, { account })
   

   The account used to make deposit and create the bucket should have positive CERE tokens balance.

3. Create a public bucket

   const clusterId = '0x...';
   const tx = blockchain.ddcCustomers.createBucket(clusterId, { isPublic: true });
   
   const { events } = await blockchain.send(tx, { account })
   const [bucketId] = blockchain.ddcCustomers.extractCreatedBucketIds(events);
   
   console.log('Bucket ID', bucketId);
