Anchor Staking

SOL staking program with points-based rewards.

How it Works

• Stake SOL → Earn 1 point per token per day
• Unstake SOL → Withdraw staked amount
• Claim → Withdraw rewards (vault - staked)

Accounts

Account	PDA Seed	Purpose
Config	stake + owner	Stores staked amount, points, timestamps
Vault	vault + owner	Holds staked SOL + rewards

Instructions

Initialize

Creates Config and Vault PDAs for the user.

await program.methods.initialize().accounts({
  owner: user.publicKey,
}).pubkeys({
  config: findConfigAddress(user.publicKey),
  vault: findVaultAddress(user.publicKey),
}).rpc();

Stake

Transfer SOL to vault, update staked amount.

await program.methods.stake(new BN(amount)).accounts({
  owner: user.publicKey,
  config: findConfigAddress(user.publicKey),
  vault: findVaultAddress(user.publicKey),
}).rpc();

Unstake

Withdraw staked SOL, reset points on withdrawn amount.

await program.methods.unstake(new BN(amount)).accounts({
  owner: user.publicKey,
  config: findConfigAddress(user.publicKey),
  vault: findVaultAddress(user.publicKey),
}).rpc();

Claim

Transfer accumulated points as rewards.

await program.methods.claim().accounts({
  owner: user.publicKey,
  config: findConfigAddress(user.publicKey),
  vault: findVaultAddress(user.publicKey),
}).rpc();

Points Calculation

earned = staked_amount * (elapsed_seconds / 86400)

1 point per token per day.
