Four npm packages disguised as cryptographic tools steal developer credentials and send them to attacker-controlled Telegram infrastructure.
@fuul/sdk
Advanced tools
Run one of the following commands to add Fuul SDK to your project:
Npm:
npm install @fuul/sdk
Yarn:
yarn add @fuul/sdk
Before using the SDK you must initialize it by supplying your Fuul issued API key.
NOTE: Be sure to do this at the root of your app so you have the SDK ready for use just by importing it at the usage point.
import { Fuul } from ('@fuul/sdk');
Fuul.init({ apiKey: "your-fuul-api-key" });
Now you can start sending events.
For Fuul to attribute conversion events you'll need to report the following tracking events
Projects must send this event every time a user visits a page on their website.
import { Fuul } from ('@fuul/sdk');
await Fuul.sendPageview();
Projects must send this event every time users connect a wallet to their website.
import { Fuul } from ('@fuul/sdk');
await Fuul.identifyUser({
userIdentifier: "0xe06099DbbF626892397f9A74C7f42F16748292Db",
identifierType: UserIdentifierType.EvmAddress,
signature: "0xb823038d78e541470946e5125b74878c226a84f891671946f18fbe7e5995171731b92f569c3e83f1c9fb89c5351245494c5d2ce6273f74c853a2cace6073f09c1c",
message: "Connect wallet"
});
NOTE: Make sure to send the event when connecting a wallet for the first time as well as when changing wallets during the session.
