🔑 Key Concepts Demonstrated

1. Program Derived Addresses (PDAs) 

// Rust: PDA derivation
let (config_pda, bump) = Pubkey::find_program_address(
    &[b"program_config"],
    program_id
);

// TypeScript: Same derivation
const [configPda, bump] = PublicKey.findProgramAddressSync(
  [Buffer.from('program_config')],
  programId
);

2. Cross-Program Invocation (CPI) 

// Rust: Call another program
counter_program::cpi::increment(
    CpiContext::new(
        ctx.accounts.counter_program.to_account_info(),
        counter_program::cpi::accounts::Increment {
            counter: ctx.accounts.counter.to_account_info(),
        },
    )
)?;

3. PDA Signing 

// Rust: PDA signs transaction
let seeds = &[SEED_TOKEN_VAULT, &[vault_bump]];
let signer = &[&seeds[..]];

system_program::transfer(
    CpiContext::new_with_signer(
        ctx.accounts.system_program.to_account_info(),
        Transfer { from, to },
        signer,
    ),
    amount,
)?;

4. Type-Safe Frontend 

// TypeScript: Fully typed program interaction
const tx = await program.methods
  .createUserAccount()
  .accountsPartial({
    authority: wallet.publicKey,
    systemProgram: SystemProgram.programId,
  })
  .rpc();

🚦 Getting Help

Common Issues:

  1. Build fails: Run anchor clean && anchor build
  2. Tests fail: Ensure local validator is NOT running during anchor test
  3. Frontend errors: Check program IDs in .env.local
  4. Type errors: Rebuild programs and copy fresh IDL/types

Development Tips:

  • Use solana logs to debug transactions
  • Check target/idl/*.json for instruction names
  • Read error codes in programs/*/src/error.rs
  • Test locally before deploying to devnet

Built with ❤️ using Anchor, Solana, and Next.js
