Title:
How to Get Staking Rewards for Each Epoch on Solana using @solana/web3.js
Introduction:
Solana is a decentralized blockchain platform that enables fast, secure, and energy-efficient staking. In this article, we’ll show you how to collect the total staking rewards for each epoch using the @solana/web3.js library.
Step 1: Set up the connection
First, make sure you have the Solana Web3.js library installed in your project. You can install it using npm or yarn:
npm install @solana/web3.js
or
yarn add @solana/web3.js
Step 2: Create a staking pool
Create a new stake pool on Solana by calling the createStakePool function from the web3 module:
import { web3 } from '@solana/web3.js';
const connection = web3.connect();
const stakePoolId = 'your_stake_pool_id'; // Replace with your stake pool id
connection.getStakingPools()
.then((pools) => {
const stakingPool = pools.find((pool) => pool.id === stakePoolId);
if (!stakingPool) {
console.error('Invalid stake pool ID');
return;
}
console.log(stakingPool);
})
.catch((error) => {
console.error(error);
});
Step 3: Collect the total staking rewards for each epoch
Use the getEpochRewards function to collect the total staking rewards for each epoch:
connection.getEpochRewards(stakingPool.id)
.then((rewards) => {
const totalRewards = rewards.reduce((acc, reward) => acc + reward.amount, 0);
console.log(Total Staking Rewards: ${totalRewards});
})
.catch((error) => {
console.error(error);
});
Step 4: Aggregate the rewards data
To aggregate the rewards data for each epoch, you can use a library like @solana/web3.js/api-rewards or create your own custom function. Here’s an example using the latter:
async function getEpochRewardsForEachEpoch() {
const stakingPoolId = 'your_stake_pool_id'; // Replace with your stake pool id
connection.getStakingPools()
.then((pools) => {
const stakingPool = pools.find((pool) => pool.id === stakePoolId);
if (!stakingPool) {
console.error('Invalid stake pool ID');
return;
}
const rewardsForEpochs = await Promise.all(stakingPool.epochs.map(async (epoch) => {
const rewardsData = await getRewardsFromEpoch(epoch);
return { epoch: epoch.toNumber(), totalRewards: rewardsData.total };
}));
console.log(rewardsForEpochs);
})
.catch((error) => {
console.error(error);
});
}
async function getRewardsFromEpoch(epoch) {
// Implement logic to retrieve rewards data from the epoch
// For example:
const rewards = await connection.getEpochRewards(epoch.toNumber());
return { total: rewards.total, data: rewards.data };
}
Conclusion:
This article demonstrates how to collect the total staking rewards for each epoch on Solana using @solana/web3.js. By following these steps, you can aggregate the rewards data and get a comprehensive view of your stake pool’s performance.
Remember to replace your_stake_pool_id with your actual stake pool ID and implement the logic to retrieve rewards data from an epoch.
