@everstake/wallet-sdk

Wallet SDK Polygon for Javascript

Getting started

npm install @everstake/wallet-sdk-polygon

Setup Wallet SDK Polygon

After installing the app, you can then import and use the SDK:

import * as polygon from 'everstake-wallet-sdk';

Wallet SDK Polygon Setup

The setup namespace contains methods used for setup SDK. The unique methods to the setup namespace are:

• setup(apiUrl): This function setup your eth-mainnet api url.

You Can Take ETH Mainnet Api

• Infura
• Alchemy
• Zmok
• Rivet Cloud
• ChainStack
• or any other option

Wallet SDK Polygon Getting Info

The get namespace contains methods used for getting info. The unique methods to the get namespace are:

• getReward(publicKey): Gets the user's reward balance in tokens.
• getTotalDelegate(publicKey): Gets the user's delegate balance in tokens.
• getUnbond(publicKey): Gets the user's unbond balance in tokens.

Wallet SDK Polygon Delegate

The delegate namespace contains methods used for sending transactions on delegation. The unique methods to the delegate namespace are:

• approve(publicKey, privateKey, amount): Approve of the amount for further debiting by a smart contract.
• delegate(publicKey, privateKey, amount): Delegate user tokens.

Wallet SDK Polygon Transaction

The transaction namespace contains methods used for sending transactions. The unique methods to the transaction namespace are:

• unstake(publicKey, privateKey, amount): Unstake user tokens.
• reward(publicKey, privateKey): Reward user tokens (Claim reward).
• restake(publicKey, privateKey): Restake user tokens (Claim reward and auto delegate them).

Wallet SDK Polygon Loading

The loading namespace contains methods used for getting info about loading transaction. The unique methods to the loading namespace are:

• isTransactionLoading(hash): Waits for a transaction to be processed and returns the status of the transaction.

Usage Examples

Below are examples of usage.

Setup Function

// Import SDK
import * as polygon from '@everstake/wallet-sdk-polygon';
// https url api ethereum mainnet.
const apiUrl = process.env.API_URL_ETH_MAINNET; // https://eth-mainnet/CD4GB...mrMj5
// Setup SDK
await polygon.setup(apiUrl);

Getting Info

// Import SDK
import * as polygon from '@everstake/wallet-sdk-polygon';
// https url api ethereum mainnet.
const apiUrl = process.env.API_URL_ETH_MAINNET; // https://eth-mainnet/CD4GB...mrMj5
// Setup SDK
await polygon.setup(apiUrl);

// User wallet address.
const publicKey = '0x4D3F0BF20Dd5DA8C6800c5cA17d721131E366651';

// Gets the user's reward balance in tokens.
const getReward = await polygon.getReward(publicKey);
console.log(getReward); // 3.34036438662955358 (MATIC)

// Gets the user's delegate balance in tokens.
const getTotalDelegate = await polygon.getTotalDelegate(publicKey);
console.log(getTotalDelegate); // 20.5000000000000000 (MATIC)

// Gets the user's unbond balance in tokens.
const getUnbond = await polygon.getUnbond(publicKey);
console.log(getUnbond); // 2.2000000000000000 (MATIC)

Delegate Polygon

// Import SDK
import * as polygon from '@everstake/wallet-sdk-polygon';
// https url api ethereum mainnet.
const apiUrl = process.env.API_URL_ETH_MAINNET; // https://eth-mainnet/CD4GB...mrMj5
// Setup SDK
await polygon.setup(apiUrl);

// User wallet address.
const publicKey = '0x7CB380672D37E6Cc2e1dE28616076Cf3CCbdb82C';
// User private key.
const privateKey = process.env.PRIVATE_KEY; // 2f92e...6761b
// The amount that the user delegates.
const amountDalegate = 10; // min value 1 (MATIC)

// Step 1 - Approve
const approve = await polygon.approve(publicKey, privateKey, amountDalegate);
console.log(approve); // if approve returns true or transaction info.

// Step 2 - Delegate
const delegateHash = await polygon.delegate(publicKey, privateKey, amountDalegate);
console.log(delegateHash); // return transaction info.

// Step 3 - Completed delegated
const loading = await polygon.isTransactionLoading(delegateHash);
console.log(loading); // returns true or false until the transaction status is either success or failed.

Other Transaction

// Import SDK
import * as polygon from '@everstake/wallet-sdk-polygon';
// https url api ethereum mainnet.
const apiUrl = process.env.API_URL_ETH_MAINNET; // https://eth-mainnet/CD4GB...mrMj5
// Setup SDK
await polygon.setup(apiUrl);

// User wallet address.
const publicKey = '0x7CB380672D37E6Cc2e1dE28616076Cf3CCbdb82C';
// User private key.
const privateKey = process.env.PRIVATE_KEY; // 2f92e...6761b
// The amount that the user delegates.
const amountUnstake = 5;

// Unstake user tokens.
const unstake = await polygon.unstake(publicKey, privateKey, amountUnstake);
console.log(unstake); // return transaction info.

// Reward user tokens (Claim reward).
const reward = await polygon.reward(publicKey, privateKey);
console.log(reward); // return transaction info.

// Restake user tokens (Claim reward and auto delegate them).
const restake = await polygon.restake(publicKey, privateKey);
console.log(restake); // return transaction info.

Loading Transaction

// Import SDK
import * as polygon from '@everstake/wallet-sdk-polygon';
// https url api ethereum mainnet.
const apiUrl = process.env.API_URL_ETH_MAINNET; // https://eth-mainnet/CD4GB...mrMj5
// Setup SDK
await polygon.setup(apiUrl);

// Hash transaction
const hash = '0x6a65103f50d40eb94b04fba1161e0dd44962f070bdcfc4c75b105ca37b2b08b2';

const loading = await polygon.isTransactionLoading(hash);
console.log(loading); // returns true or false until the transaction status is either success or failed
