BLOCKS SDK

This application leverages the multi-chain BLOCKS data feature to store and fetch data on the blockchain. It includes hot-wallet functionality to facilitate transactions across the various BLOCKS supported chains.

Use Cases for the BLOCKS SDK

• Add blockchain data utility to your application
• Leverage immutable data for records, verification, origin tracking etc.

Project Notes:

• Project is set up for Ethereum, Polygon, Gnosis, Goerli.
• Internal hot-wallet is used as the provider to sign transactions.

Examples

/* Export a private key from a wallet such as Metamask. 
This wallet will need gas and BLOCKS tokens for any of the networks 
you wish to run transactions on. */

/* Initialize the SDK. Make sure to store your privateKey as an environment
variable. */

const blocks = new Blocks({ privateKey: 'yourPrivateKey'});

/* Create Data: Enter your data as a string or stringified JSON. The SDK
will hexadecimalize it for the blockchain */

const result = await blocks.createData('Hello again!','ethereum',undefined,undefined,1.3);

/* Fetch Data: Provide a transaction hash that contains data, and the 
SDK will return the data string from the blockchain. */

const result = await blocks.fetchData('0xb8115e9b4bd4881b87ad3af61e1099c762125de7c7db627b33f821f19b110156','ethereum');
