A JavaScript/TypeScript library for development of DApps using Blade Wallet on Hedera Network
Read the TypeDoc API documentation
For example usage and testing the below APIs using a Demo App, please go here and setup the app locally:
The hosted version of the Demo App can be used to try out some API calls:
Blade Wallet uses the Hedera Signature and Wallet Interface as defined here.
This package is available as a NPM package.
npm install @bladelabs/blade-web3.js
The BladeSigner class implements the Hashgraph Signer interface and allows access to Blade Wallet operations.
To interact with the Blade Extension programmatically, instantiate a BladeSigner object and create a new session.
import {BladeSigner} from 'blade-web3.js';
initBlade();
async function initBlade() {
const bladeSigner = new BladeSigner();
await bladeSigner.createSession();
// bladeSigner object can now be used.
bladeSigner.getAccountId();
}
you can then communicate with the Extension using the BladeSigner object using the Hedera Signer interface:
| API | Description |
|---|---|
bladeSigner.getAccountId() |
Get accountId of active account. |
bladeSigner.getAccountBalance( accountId:AccountId|string) |
|
bladeSigner.getAccountInfo( accountId:AccountId|string) |
Get information about a Hedera account on the connected network. |
bladeSigner.checkTransaction(transaction:Transaction) |
Check that a transaction is valid. |
bladeSigner.populateTransaction(transaction:Transaction) |
Set transaction id with active account. |
bladeSigner.sendRequest(request:Executable) |
Sign and execute a transaction with provider account. |
bladeSigner.signTransaction(transaction:Transaction) |
Sign a transaction with active wallet account. |
bladeSigner.getLedgerId() |
Ledger Id of the currently connected network. |
bladeSigner.getMirrorNetwork() |
Return array of mirror nodes for the current network. |
bladeSigner.getNetwork() |
Get map of nodes for the current hedera network. |
import { TransferTransaction } from '@hashgraph/sdk';
const amount = new BigNumber(5);
const transaction = new TransferTransaction(
{
hbarTransfers: [{
accountId: destinationAccountId,
amount: amount
},
{
accountId: bladeSigner.getAccountId(),
amount: amount.negated()
}
]
}
);
const result = await bladeSigner.sendRequest(transaction);
import { TransactionReceiptQuery } from '@hashgraph/sdk';
const result = await bladeSigner.sendRequest( new TransactionReceiptQuery({transactionId:transactionId}));
