Solana Staking Program

This program allows users to stake SOL tokens, accumulate reward points over time based on the staked amount, and claim those points.

Features

• Create a PDA account to store user staking data.
• Stake SOL tokens to start earning points.
• Unstake SOL tokens to withdraw your stake.
• Claim accumulated reward points.
• Check current points without claiming.

How it works

• When you stake SOL, the program tracks your staked amount and the time.
• Points are calculated based on the amount staked and the time elapsed.
• You can unstake any amount up to your staked balance.
• Points can be claimed separately.
• The program uses PDAs to securely manage each user’s staking data.
