Practical overview
When it fits
Use it when you need the documented browser-extension wallet flow for a Nebulas account, or when a Nebulas dApp needs to communicate with the wallet through NebPay or postMessage.
Who it is for
- Nebulas users who want to manage a wallet in a browser extension and send NAS.
- Developers building Nebulas dApps that need to request contract actions or an account address from the extension.
Documented uses
- Create a wallet and download its keystore file.
- Import a keystore file and store the account in the extension.
- Send NAS to another account and inspect transaction status by hash.
- Connect a dApp to request smart-contract transactions or the current account address.
Requirements & limits
The repository links to a Chrome Web Store listing for the extension. For testing local HTML files, its README says to enable “Allow access to file URLs” in the extension management page.
- The documented ecosystem is Nebulas, and the transfer asset described is NAS.
- DApp developers can choose between NebPay SDK calls and direct postMessage communication.
- Transaction status lookup uses the transaction hash shown after sending.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Create and use a Nebulas wallet to send NAS
Create a wallet or import a keystore, then send NAS and look up the resulting transaction status.
Before you start
- The WebExtensionWallet browser extension.
- A keystore file to import when using an existing account.
Steps
In the New-Wallet tab, create a wallet and download its keystore file, or proceed with an existing keyfile.
In the Send-TX tab, import the keystore file; the account is then stored in the extension.
Send NAS to another account address.
Check the transaction by clicking its displayed hash in Send-TX, or copy the hash into check-TX.
Expected outcome
A NAS transfer is submitted and its status can be viewed using the transaction hash.
Guide limitations
- The README does not specify transfer fees, confirmation times, or supported network configuration.
