blocks_sdk v1.0.0
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');BLOCKS Tokens
