Solzempic

A lightweight, zero-overhead framework for building Solana programs with Pinocchio.

Solzempic provides the structure and safety of a framework without the bloat. It implements the Action pattern (Build, Validate, Execute) and provides type-safe account wrappers while maintaining full control over compute unit usage.

Why Solzempic?

The Problem with Existing Frameworks

Anchor is excellent for getting started, but comes with significant overhead:

Magic discriminators and automatic deserialization add ~2000+ CUs per instruction
IDL generation bloats binary size
Implicit borsh serialization prevents zero-copy optimizations
Hard to reason about exactly what code is generated

Vanilla Pinocchio gives maximum control, but requires writing boilerplate:

Account validation logic repeated across instructions
No structured pattern for instruction processing
Easy to forget security checks

Solzempic's Approach

Solzempic provides just enough structure to eliminate boilerplate while maintaining zero overhead:

+------------------+---------------+------------------+
|     Anchor       |   Solzempic   | Vanilla Pinocchio|
+------------------+---------------+------------------+
| High abstraction | Right balance | No abstraction   |
| Hidden costs     | Explicit      | Explicit         |
| Magic macros     | Thin macros   | No macros        |
| ~5000 CU/instr   | ~100 CU/instr | ~100 CU/instr    |
+------------------+---------------+------------------+

Key Features

Zero-overhead abstractions: All wrappers compile to the same code you'd write by hand
Action pattern: Structured Build -> Validate -> Execute flow for every instruction
Type-safe account wrappers: AccountRef<T>, AccountRefMut<T> with ownership validation
Program-specific Framework trait: Configure your program ID once, use everywhere
Validated program accounts: SystemProgram, TokenProgram, Signer etc. with compile-time guarantees
Derive macros: #[instruction] and #[SolzempicEntrypoint] for ergonomic dispatch
no_std compatible: Works in constrained Solana runtime environment

Installation

Add to your Cargo.toml:

[dependencies]
solzempic = { version = "0.1" }
pinocchio = { version = "0.7" }
bytemuck = { version = "1.14", features = ["derive"] }

Quick Start

1. Define Your Program Entry Point

In your program's lib.rs, use the #[SolzempicEntrypoint] attribute:

#![no_std]

use solzempic::SolzempicEntrypoint;

#[SolzempicEntrypoint("YourProgramId111111111111111111111111111")]
pub enum MyInstruction {
    Initialize = 0,
    Increment = 1,
}

This single attribute generates:

ID: Pubkey constant and id() -> &'static Pubkey function
AccountRef<'a, T>, AccountRefMut<'a, T>, ShardRefContext<'a, T>, ShardRefMutContext<'a, T> type aliases
#[repr(u8)] on the enum
TryFrom<u8> and dispatch methods
The program entrypoint

2. Define Account Types

#[solzempic::account(discriminator = 1)]
pub struct Counter {
    pub discriminator: [u8; 8],
    pub owner: Pubkey,
    pub count: u64,
}

The #[account(discriminator = N)] macro automatically:

Adds #[repr(C)], Pod, Zeroable derives
Implements Loadable and Account traits
Generates LEN, DISCRIMINATOR, and discriminator() method

3. Implement an Instruction

Use the #[instruction] attribute on an impl block:

use solzempic::{instruction, Signer, ValidatedAccount};
use pinocchio::{AccountView, program_error::ProgramError, ProgramResult};
use solana_address::Address;

#[repr(C)]
#[derive(Clone, Copy)]
pub struct IncrementParams {
    pub amount: u64,
}

pub struct Increment<'a> {
    pub counter: AccountRefMut<'a, Counter>,
    pub owner: Signer<'a>,
}

#[instruction(IncrementParams)]
impl<'a> Increment<'a> {
    fn build(accounts: &'a [AccountView], _params: &IncrementParams) -> Result<Self, ProgramError> {
        if accounts.len() < 2 {
            return Err(ProgramError::NotEnoughAccountKeys);
        }
        Ok(Self {
            counter: AccountRefMut::load(&accounts[0])?,
            owner: Signer::wrap(&accounts[1])?,
        })
    }

    fn validate(&self, _program_id: &Address, _params: &IncrementParams) -> ProgramResult {
        // Verify owner matches counter's owner
        if self.owner.key() != &self.counter.get().owner {
            return Err(ProgramError::IllegalOwner);
        }
        Ok(())
    }

    fn execute(&self, _program_id: &Address, params: &IncrementParams) -> ProgramResult {
        self.counter.get_mut().count += params.amount;
        Ok(())
    }
}

4. Process Instructions

The #[SolzempicEntrypoint] macro generates everything needed. Your process_instruction is simply:

fn process_instruction(
    program_id: &Address,
    accounts: &[AccountView],
    data: &[u8],
) -> ProgramResult {
    MyInstruction::process(program_id, accounts, data)
}

Core Concepts

The Action Pattern

Every instruction follows the same three-phase pattern:

┌─────────────────────────────────────────────────────────────────────────┐

Phase 1: Build

Extract parameters from instruction data (zero-copy via parse_params)
Load and validate account types (AccountRef::load, AccountRefMut::load)
Wrap program accounts (Signer::wrap, TokenProgram::wrap)
Fail fast on structural errors

Phase 2: Validate

Check business logic invariants
Verify PDA derivations if needed
Validate numerical ranges and relationships
No state mutations allowed

Phase 3: Execute

Perform all state changes
Execute token transfers
Make CPI calls
This is the "point of no return"

Account Wrappers

`AccountRef<T>` - Read-Only Access

pub struct AccountRef<'a, T: Loadable, F: Framework> {
    pub info: &'a AccountInfo,
    data: &'a [u8],
    // ...
}

impl<'a, T: Loadable, F: Framework> AccountRef<'a, T, F> {
    /// Load with full validation (ownership + discriminator)
    pub fn load(info: &'a AccountInfo) -> Result<Self, ProgramError>;

    /// Load without ownership check (for cross-program reads)
    pub fn load_unchecked(info: &'a AccountInfo) -> Result<Self, ProgramError>;

    /// Get typed reference to account data
    pub fn get(&self) -> &T;

    /// Check if account is a PDA with given seeds
    pub fn is_pda(&self, seeds: &[&[u8]]) -> (bool, u8);
}

`AccountRefMut<T>` - Read-Write Access

impl<'a, T: Loadable, F: Framework> AccountRefMut<'a, T, F> {
    /// Load with validation (ownership + discriminator + is_writable)
    pub fn load(info: &'a AccountInfo) -> Result<Self, ProgramError>;

    /// Get typed reference
    pub fn get(&self) -> &T;

    /// Get mutable typed reference
    pub fn get_mut(&mut self) -> &mut T;

    /// Reload after CPI (updates internal data pointer)
    pub fn reload(&mut self);
}

impl<'a, T: Initializable, F: Framework> AccountRefMut<'a, T, F> {
    /// Initialize a new account (writes discriminator, zeros rest)
    pub fn init(info: &'a AccountInfo) -> Result<Self, ProgramError>;

    /// Initialize if uninitialized, otherwise load
    pub fn init_if_needed(info: &'a AccountInfo) -> Result<Self, ProgramError>;

    /// Initialize a PDA account (create via CPI + initialize)
    pub fn init_pda(
        info: &'a AccountInfo,
        payer: &AccountInfo,
        system_program: &AccountInfo,
        seeds: &[&[u8]],
        space: usize,
    ) -> Result<Self, ProgramError>;
}

`ShardRefContext<T>` - Read-Only Triplet Navigation

For sharded data structures that need read-only access to prev/current/next:

pub struct ShardRefContext<'a, T: Loadable, F: Framework> {
    pub prev: AccountRef<'a, T, F>,
    pub current: AccountRef<'a, T, F>,
    pub next: AccountRef<'a, T, F>,
}

impl<'a, T: Loadable, F: Framework> ShardRefContext<'a, T, F> {
    pub fn new(prev: &'a AccountInfo, current: &'a AccountInfo, next: &'a AccountInfo) -> Result<Self, ProgramError>;
    pub fn current(&self) -> &T;
    pub fn prev(&self) -> &T;
    pub fn next(&self) -> &T;
}

`ShardRefMutContext<T>` - Mutable Triplet Navigation

For sharded data structures that need mutable access to prev/current/next:

pub struct ShardRefMutContext<'a, T: Loadable, F: Framework> {
    pub prev: AccountRefMut<'a, T, F>,
    pub current: AccountRefMut<'a, T, F>,
    pub next: AccountRefMut<'a, T, F>,
}

impl<'a, T: Loadable, F: Framework> ShardRefMutContext<'a, T, F> {
    pub fn new(prev: &'a AccountInfo, current: &'a AccountInfo, next: &'a AccountInfo) -> Result<Self, ProgramError>;
    pub fn from_loaded(prev: AccountRefMut, current: AccountRefMut, next: AccountRefMut) -> Self;
    pub fn current_mut(&mut self) -> &mut T;
    pub fn prev_mut(&mut self) -> &mut T;
    pub fn next_mut(&mut self) -> &mut T;
    pub fn all_mut(&mut self) -> (&mut T, &mut T, &mut T);
}

Common use cases for shard contexts:

Orderbooks: Orders may need to move between price-range shards
Linked lists: Insertions/deletions update prev/next pointers
Rebalancing: Moving data between under/over-utilized shards

PDA (Program Derived Address) Support

Solzempic provides comprehensive PDA support through the account wrappers:

Validating PDAs

Both AccountRef and AccountRefMut implement the is_pda() method via the AsAccountRef trait:

let seeds = &[b"user", owner.key().as_ref()];
let (is_valid, bump) = account.is_pda(seeds);

if !is_valid {
    return Err(ProgramError::InvalidSeeds);
}

// Store bump for later use in CPI signing
let full_seeds = &[b"user", owner.key().as_ref(), &[bump]];

Performance note: PDA derivation costs ~2000 CUs. If you validate frequently, consider storing the bump in your account data and using a simple key comparison instead.

Creating PDA Accounts

Use AccountRefMut::init_pda() to create and initialize a PDA in one operation:

// Derive PDA and get bump
let (_, bump) = Pubkey::find_program_address(
    &[b"market", base_mint.as_ref(), quote_mint.as_ref()],
    &program_id,
);

// Include bump in seeds
let seeds: &[&[u8]] = &[
    b"market",
    base_mint.as_ref(),
    quote_mint.as_ref(),
    &[bump],
];

// Create PDA and initialize with discriminator
let mut market: AccountRefMut<Market> = AccountRefMut::init_pda(
    market_account,
    payer.info(),
    system_program.info(),
    seeds,
    Market::LEN,
)?;

// Set initial values
market.get_mut().admin = *admin.key();

For lower-level control, use the create_pda_account() function:

use solzempic::create_pda_account;

// Create without initialization
create_pda_account(payer, new_account, &program_id, space, seeds)?;

The `AsAccountRef` Trait

The AsAccountRef trait provides a common interface for PDA validation on both read-only and writable accounts:

pub trait AsAccountRef<'a, T: Loadable, F: Framework> {
    fn info(&self) -> &'a AccountView;
    fn address(&self) -> &Address;
    fn get(&self) -> &T;
    fn is_pda(&self, seeds: &[&[u8]]) -> (bool, u8);
}

This allows generic code to work with either AccountRef or AccountRefMut:

fn validate_pda<'a, T, F, A>(account: &A, seeds: &[&[u8]]) -> ProgramResult
where
    T: Loadable,
    F: Framework,
    A: AsAccountRef<'a, T, F>,
{
    let (is_valid, _bump) = account.is_pda(seeds);
    if !is_valid {
        return Err(ProgramError::InvalidSeeds);
    }
    Ok(())
}

Validated Program Wrappers

All program and sysvar accounts validate their identity on construction:

// Programs
let system = SystemProgram::wrap(&accounts[0])?;      // Validates key == 11111...
let token = TokenProgram::wrap(&accounts[1])?;        // Validates SPL Token or Token-2022
let ata = AtaProgram::wrap(&accounts[2])?;            // Validates ATA program

// Signers
let signer = Signer::wrap(&accounts[3])?;             // Validates is_signer flag
let payer = Payer::wrap(&accounts[4])?;               // Alias for Signer

// Sysvars
let clock = ClockSysvar::wrap(&accounts[5])?;         // Validates Clock sysvar ID
let rent = RentSysvar::wrap(&accounts[6])?;           // Validates Rent sysvar ID

// Token accounts
let mint = Mint::wrap(&accounts[7])?;                 // Validates token program ownership
let token = TokenAccountRefMut::load(&accounts[8])?;   // Validates token account
let token_account = TokenAccountRefMut::load(&accounts[9])?;

The `Framework` Trait

The Framework trait allows account wrappers to know your program's ID without passing it everywhere:

pub trait Framework {
    const PROGRAM_ID: Pubkey;
}

// define_framework! generates:
pub struct Solzempic;
impl Framework for Solzempic {
    const PROGRAM_ID: Pubkey = YOUR_PROGRAM_ID;
}

// Which allows:
AccountRefMut::<MyAccount>::load(&account)?  // Automatically checks owner == YOUR_PROGRAM_ID

Derive Macros

`#[SolzempicEntrypoint("program_id")]`

The main entrypoint attribute that generates everything needed for your program:

#[SolzempicEntrypoint("Your11111111111111111111111111111111111111")]
pub enum MyInstruction {
    Initialize = 0,
    Transfer = 1,
    Close = 2,
}

// Generates:
// - pub const ID: Address = ...
// - pub fn id() -> &'static Address
// - pub type AccountRef<'a, T> = ...
// - pub type AccountRefMut<'a, T> = ...
// - pub type ShardRefContext<'a, T> = ...
// - pub type ShardRefMutContext<'a, T> = ...
// - #[repr(u8)] on the enum
// - TryFrom<u8> for MyInstruction
// - MyInstruction::process() dispatch method
// - The program entrypoint

`#[instruction(ParamsType)]`

Implements the Instruction trait on an impl block:

pub struct Transfer<'a> {
    pub from: AccountRefMut<'a, TokenAccount>,
    pub to: AccountRefMut<'a, TokenAccount>,
    pub authority: Signer<'a>,
}

#[instruction(TransferParams)]
impl<'a> Transfer<'a> {
    fn build(accounts: &'a [AccountView], params: &TransferParams) -> Result<Self, ProgramError> { ... }
    fn validate(&self, program_id: &Address, params: &TransferParams) -> ProgramResult { ... }
    fn execute(&self, program_id: &Address, params: &TransferParams) -> ProgramResult { ... }
}

// Generates InstructionParams and Instruction trait implementations

Performance Characteristics

Solzempic adds no runtime overhead beyond what you'd write by hand:

Account loading: Single borrow, no copies
Parameter parsing: Zero-copy pointer cast
Discriminator checks: Single byte comparison
Program validation: Pubkey comparison (32-byte memcmp)

All wrapper methods are #[inline] and compile away in release builds.

Typical instruction overhead:

Parse params: ~10 CUs
Load AccountRefMut: ~50 CUs (borrow + discriminator check)
Wrap Signer: ~20 CUs (is_signer check)

ProgramError::InvalidAccountData     // Wrong discriminator or not writable
ProgramError::AccountAlreadyInitialized  // init() on initialized account
ProgramError::IncorrectProgramId     // Wrong program/sysvar ID
ProgramError::MissingRequiredSignature   // Signer check failed
ProgramError::NotEnoughAccountKeys   // Too few accounts passed
ProgramError::InvalidInstructionData // Params too short

Define your own errors by implementing Into<ProgramError>:

#[repr(u32)]
pub enum MyError {
    InvalidPrice = 1000,
    OrderNotFound = 1001,
}

impl From<MyError> for ProgramError {
    fn from(e: MyError) -> Self {
        ProgramError::Custom(e as u32)
    }
}

Best Practices

Fail fast in build(): Validate account structure early
Keep validate() pure: No state changes, only checks
Document account order: Use comments to specify expected accounts
Use #[inline(always)]: For hot paths in execute()
Prefer AccountRefMut::init_pda(): For PDA creation with initialization
Call reload() after CPI: If you modify accounts via CPI
