Prerequisites ​

Packages ​

In order to perform the operations mentioned in this documentation using everscale-inpage-provider , the target contracts artifacts, including the contract tvc and code, are required. These artifacts can be obtained using the locklift build command, which generates the necessary files.

For the sake of simplicity, a simple npm package named tip3-docs-artifacts has been provided that contains the required artifacts of the TokenRoot , TokenWallet , Wallet , and the default custom smart contract.

The necessary npm packages are as follows:

• everscale-inpage-provider
• everscale-standalone-client
• tip3-docs-artifacts

To install these packages, run the following command in your shell:

npm install --save-dev everscale-inpage-provider everscale-standalone-client tip3-docs-artifacts

Provider ​

The everscale-inpage-provider is used as a provider for TVM based blockchains such as Venom and Everscale. Follow the steps below to initialize and use everscale-inpage-provider in your scripts.

You can also refer to the everscale-inpage-provider Docs for detailed instructions.

Step 1: Create the module ​

Create a file named useProvider.ts.

Step 2: Add Scripts ​

Add the following script to the file you just made:

// Import the required libraries
import { ProviderRpcClient, Address } from "everscale-inpage-provider";

// Initialize the provider
const provider: ProviderRpcClient = new ProviderRpcClient();

// Make sure the provider is initialized.
await provider.ensureInitialized();

// Request permissions from the user to execute API
await provider.requestPermissions({
  permissions: ["basic", "accountInteraction"],
});

// setting the ever sender address
const providerAddress: Address = (await provider.getProviderState())
.permissions.accountInteraction!.address;

export {provider,  providerAddress};

From now we can use the provider object and the provider address in our scripts by just simply importing them.
