Steem Blockchain Local Broadcast JavaScript Tool
Hi thereš
It's been a while since I have posted on Steemit, I was away from posting and updating witness activities because the MSS Exam is going on at my University, almost at the end of my University academic lifeš
This project is designed to make it easier for developers and Steem users to interact with the Steem blockchain using JavaScript while locally hosting, the scripts and tools run on your local machine, allowing you to interact with the Steem blockchain directly from your computer. For now, I have created only two features for delegating STEEM Power and returning delegations, I will add more features in future. If you are worried about your private keys being exposed this is really for you!
What Does This Project Do?
The project provides a set of JavaScript scripts that allow you to:
- Delegate STEEM Power (VESTS): Easily delegate STEEM Power to other accounts.
- Return Delegated STEEM Power: Return delegated STEEM Power from other accounts.
- User-Friendly Input: Specify amounts in STEEM instead of VESTS for convenience.
How to Get Started
Prerequisites
Before running the scripts, make sure you have the following installed:
Installation
Clone the repository:
git clone https://github.com/Steemblocks/Steem-Local-Broadcast.git cd Steem-Local-BroadcastInstall the required dependencies:
npm installEdit the
config.jsfile and add your Steem account details:username: 'your-userid', // Replace with your Steem username activeKey: 'your-active-key', // Replace with your active private key
How to Use the Scripts
Delegate STEEM Power
To delegate STEEM Power to another account, use the steemDelegate.js script:
node steemDelegate.js <delegatee> <steemAmount>
<delegatee>: The account you want to delegate to.<steemAmount>: The amount of STEEM to delegate.
Example:
node steemDelegate.js "the-gorilla" 100
This delegates 100 STEEM worth of VESTS to the account the-gorilla.
Output example: You will get a response like this
PS C:\Users\hp\Downloads\Steem Local Broadcast> node steemDelegate.js "the-gorilla" 100
Delegation Transaction: {
id: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
block_num: 94060xxxx,
trx_num: x,
expired: false,
ref_block_num: 15xxx,
ref_block_prefix: 2618191xxxxx,
expiration: '2025-03-23T06:43:24',
operations: [ [ 'delegate_vesting_shares', [Object] ] ],
extensions: [],
signatures: [
'1f54d4ddc83c1d5df878bf70eefa840fde6168b5550a598429306f5a2597264fff22db70xxxxxxxxxxxxxxxxxxxx'
]
}
Return Delegated STEEM Power
To return delegated STEEM Power from another account, use the cancelDelegation.js script:
node cancelDelegation.js <delegatee> <steemAmount>
<delegatee>: The account you want to return delegation from.<steemAmount>: The amount of STEEM to return.
Example:
node cancelDelegation.js "avro33" 0.00
This returns all the STEEM delegation from the account avro33. You can then delegate again using the steemDelegate.js script.
Output example: You will get a response like this
PS C:\Users\hp\Downloads\Steem Local Broadcast> node cancelDelegation.js "avro33" 0
Return Vesting Delegation Transaction: {
id: 'ea6ad233fbe23213045dxxxxxxxxxxxxxxxx',
block_num: 940xxxx,
trx_num: 1,
expired: false,
ref_block_num: 160xx,
ref_block_prefix: 1227xxxxxx,
expiration: '2025-03-23T06:46:03',
operations: [ [ 'delegate_vesting_shares', [Object] ] ],
extensions: [],
signatures: [
'2066badbba0968066b7532349f656fb6e3a2cbf2353641d1e16402554d822xxxxxxxxxxxxxxxxxxxxxxx'
]
}
A Note on Security
While installing npm you will get security alerts and discover some high severity vulnerabilities, these are caused by the outdated dependencies in our Steem-js.
PS C:\Users\hp\Downloads\Steem Local Broadcast> npm audit report
# npm audit report
cross-fetch <=2.2.5 || 3.0.0 - 3.1.4 || 3.2.0-alpha.0 - 3.2.0-alpha.2
Severity: high
Incorrect Authorization in cross-fetch - https://github.com/advisories/GHSA-7gc6-qh9x-w6h8
Depends on vulnerable versions of node-fetch
fix available via `npm audit fix --force`
Will install [email protected], which is a breaking change
node_modules/cross-fetch
steem >=0.6.0-beta.0
Depends on vulnerable versions of cross-fetch
Depends on vulnerable versions of ws
node_modules/steem
node-fetch <2.6.7
Severity: high
node-fetch forwards secure headers to untrusted sites - https://github.com/advisories/GHSA-r683-j2x4-v87g
fix available via `npm audit fix --force`
Will install [email protected], which is a breaking change
node_modules/node-fetch
ws 2.1.0 - 5.2.3
Severity: high
ws affected by a DoS when handling a request with many HTTP headers - https://github.com/advisories/GHSA-3h5v-q93c-6h6q
fix available via `npm audit fix --force`
Will install [email protected], which is a breaking change
node_modules/ws
4 high severity vulnerabilities
To address all issues (including breaking changes), run:
npm audit fix --force
These issues are being addressed urgently, and I have informed our core developers, hoping they will update the JavaScript libraries soon.
During installation, if you run npm audit fix --force It breaks the script and doesn't work. If you keep it as it is, then it works fine. But we need the Steem-js update asap.
Contribute and Collaborate
This project is open-source, and Iād love for the community to get involved! If you have any suggestions, find bugs, or want to contribute, feel free to open an issue or submit a pull request on the GitHub repository.
Special Thanks
I would love to express my gratitude towards our seniors @steemchiller and @the-gorilla, for being always friendly, quick to help, and endlessly supportive. Weāre so proud to have you, and your dedication inspires us every day. Thank you for being amazing!
Final Thoughts
I hope this project makes it easier for developers and Steem users to interact with the blockchain. Whether youāre delegating STEEM Power or managing your delegations, these tools are designed to simplify the process.
Letās keep building and growing the Steem ecosystem together! šŖ
