Simple Stake Program

A staking program built on Solana using the Anchor framework. This program allows users to stake SPL tokens, claim rewards, and unstake their tokens after a defined duration. It provides the following features:

• Initialize staking pools with customizable parameters.
• Stake SPL tokens and earn rewards based on a reward rate.
• Claim accumulated rewards at regular intervals.
• Unstake tokens after the staking duration ends.

Setup Local Validator

To set up and run a local Solana validator:

1. Ensuring Solana CLI has been installed.

2. Set the local validator as your cluster:

   solana config set --url localhost

3. Start the local validator on a separate terminal:

   solana-test-validator

---

Deploy SPL Token on Localnet

1. Create a new SPL token using the Solana CLI:

   spl-token create-token

2. Create a token account for the mint:

   spl-token create-account <TOKEN_MINT_ADDRESS>

3. Mint tokens to the token account:

   spl-token mint <TOKEN_MINT_ADDRESS> <AMOUNT> <RECIPIENT_ACCOUNT_ADDRESS>

4. Replace mint in tests/simple_stake.ts

  const mint = new PublicKey("replace_with_newly_deployed_mint_address"); 

---

Run Tests

1. Install dependencies:

   npm install

2. Build the program:

   anchor build

3. Deploy the program to the local validator:

   anchor deploy

4. Generata a new programID and synced it across.

    solana-keygen new --outfile target/deploy/simple_stake-keypair.json

   anchor keys sync

   Also make sure you manually replace in this too.

     const programId = new PublicKey("replace_by_newly_generated");

5. Run the test cases ( make sure local validaor running on a separate terminal ):

   anchor test --skip-local-validator --skip-deploy

Test Case Details

Stake Tokens

Stakes a specified amount of tokens in the staking pool.

it("Simple Stake", async () => {
  let amountToStake = new anchor.BN(2000000000);
  let tx = await program.methods.stakeSpl(amountToStake)
    .accounts({
        ...
    })

});

Claim Rewards

Allows a staker to claim rewards from the staking pool.

it("Simple Claim", async () => {
  let tx = await program.methods.claimSpl()
    .accounts({
    ...
    })
    .signers([staker1]).rpc();
  console.log("Claim tx", tx);
});

Unstake Tokens

Unstakes a specified amount of tokens from the staking pool.

it("Simple UnStake", async () => {
  let amountToUnStake = new anchor.BN(200000000);
  let tx = await program.methods.unstakeSpl(amountToUnStake)
    .accounts({
    ...
    })
    .signers([staker1]).rpc();
  console.log("Unstake tx", tx);
});
