Farming program assignment

This is assignment is designed to help our team evaluate proficiency with the Solana programing model, focusing on the Anchor framework

This involves a building an integrated application, consisting of a frontend (React app) and a Solana program

Estimated time to complete is between 2-3 weeks

Components to build

1. Create base-user and super-user accounts
2. Build out platform program to spec
   1. Global State (PDA)
   2. pool for testToken (PDA)
   3. Deposit function: user -> pool
   4. Withdraw function: pool -> user
3. Create a second program called farm-program
   1. farm (PDA)
   2. Stake function: pool -> farm
   3. Harvest function (calls Reward Calculation function): farm -> user
   4. Unstake function (calls Harvest function): farm -> pool
   5. Reward Calculation function
   • This calculates (time elapsed since Staking * rewards per sec)
4. Create React app (with Typescript) for UI, with the ability to use all of the functionality described + sign and send transactions

Tests to be run

1. Create farm (this can be done at any step before "Stake" test)
2. Create global state
   1. Should fail if base-user tries to call this
3. Create token (mint) thru Anchor Typescript, called testToken
4. Super-user creates pool
5. Super-user mints testToken to pool
6. Super-user mints testToken to base-user
7. Base-user deposits testToken to pool
8. Base-user should fail to withdraw more than token amount the base-user deposited to pool
9. Base-user stakes testToken from pool to farm via CPI
10. Base-user harvests rewards (in the form of testToken) from farm to user via CPI
11. Base-user unstakes testToken from farm to pool via CPI, also harvesting rewards
12. Base-user withdraws testToken from pool

Requirements

• There should be a base-user and a super-user
• Typescript must be used for React app and unit-testing Solana program code
• The tester needs to be able to:
  1. clone the repo
  2. run anchor test and all tests need to pass
  3. click through each feature without failing
  4. sign and send transactions without failing

Guidelines:

• Clone repo
• Create new branch
• Create the React app in the app directory, this must use typescript
• Commits should be made often, and they should be small, preferably at each feature addition/update
• Submit PR (git push)

questions & answers

1. How could you get the real-world market price of token in the contract?

2. How do you call another contract's function in your contract?

3. How can you get account information in your contract?

4. How do you deposit SOL to your contract?

5. What is difference between devnet & testnet on Solana?
