🧩 Part 1: Token Initialization & Minting (Rust + Anchor):
use anchor_lang::prelude::*;
use anchor_spl::token::{self, Mint, TokenAccount, Token, InitializeMint, MintTo};
declare_id!("LivFi111111111111111111111111111111111111111");
#[program]
pub mod livfi_token {
use super::*;
pub fn initialize_token(
ctx: Context<InitializeToken>,
decimals: u8,
total_supply: u64,
) -> Result<()> {
// Initialize the mint
token::initialize_mint(
ctx.accounts.into_init_mint_context(),
decimals,
ctx.accounts.authority.key,
Some(ctx.accounts.authority.key),
)?;
// Mint total supply to the initial distribution wallet
token::mint_to(
ctx.accounts.into_mint_to_context(),
total_supply,
)?;
Ok(())
}
}
#[derive(Accounts)]
pub struct InitializeToken<'info> {
#[account(init, payer = authority, space = 8 + 82, mint::decimals = 9, mint::authority = authority)]

authority: self.authority.to_account_info(),
};
CpiContext::new(self.token_program.to_account_info(), cpi_accounts)
}
}
✅ What This Does:
Initializes the LIV token mint with 9 decimals
Mints the full 100B supply to the creator’s wallet
Sets up the token for further logic (tax, rewards, governance)
🧩 Part 2: Transfer Hook with Tax Breakdown
This logic:
Applies a 6% tax on transfers and sells
Splits tax into:
3% → SOL rewards pool
1.5% → Developer fund
1.2% → Liquidity reserve
0.3% → Token burn
Enforces max wallet size (2% of total supply)
⚠️ Note: Solana SPL tokens don’t have native “transfer hooks,” so we simulate this by routing transfers through a custom instruction.
🔧 Transfer With Tax Logic
use anchor_lang::prelude::*;
use anchor_spl::token::{self, TokenAccount, Token, Transfer, Burn};
#[program]
pub mod livfi_token {
use super::*;
pub fn transfer_with_tax(
ctx: Context<TransferWithTax>,
amount: u64,
) -> Result<()> {
let tax_rate = 6; // 6%
let tax_amount = amount * tax_rate / 100;
let net_amount = amount - tax_amount;
// Breakdown
let reward_amount = tax_amount * 50 / 100; // 3%
let dev_amount = tax_amount * 25 / 100; // 1.5%
let liquidity_amt = tax_amount * 20 / 100; // 1.2%
let burn_amount = tax_amount * 5 / 100; // 0.3%
// Transfer net amount to recipient
token::transfer(
ctx.accounts.into_transfer_context(),
net_amount,
)?;
// Transfer tax portions
token::transfer(
ctx.accounts.into_reward_context(),
reward_amount,
)?;
token::transfer(
ctx.accounts.into_dev_context(),
dev_amount,
)?;
token::transfer(
ctx.accounts.into_liquidity_context(),
liquidity_amt,
)?;
// Burn portion
token::burn(
ctx.accounts.into_burn_context(),
burn_amount,
)?;
// Enforce max wallet size (2% of total supply)
let recipient_balance = ctx.accounts.recipient.amount + net_amount;
let max_wallet = 2_000_000_000_000; // 2% of 100B with 9 decimals
require!(recipient_balance <= max_wallet, LivFiError::MaxWalletExceeded);
Ok(())
}

✅ What This Covers:
Tax breakdown and routing
Burn logic
Max wallet enforcement
Modular CPI contexts for clarity
🧩 Part 3: SOL Reward Distribution (Rust + Anchor)
Solana smart contracts can’t run on their own at timed intervals, so we’ll use a pull-based model triggered by a scheduled off-chain bot (e.g. a cron job or validator script). This keeps it gas-efficient and secure.
🔧 Reward Distribution Logic
use anchor_lang::prelude::*;
use anchor_lang::solana_program::system_instruction;
#[program]
pub mod livfi_token {
use super::*;
pub fn distribute_rewards(ctx: Context<DistributeRewards>) -> Result<()> {
let reward_pool = &ctx.accounts.reward_pool;
let recipients = &ctx.accounts.recipients;
let total_rewards = reward_pool.lamports();
let mut total_liv = 0u64;
// Calculate total LIV held by all recipients
for holder in recipients.iter() {
total_liv += holder.liv_balance;
}
// Distribute SOL proportionally
for holder in recipients.iter() {
let share = (holder.liv_balance as u128 * total_rewards as u128) / total_liv as u128;
let share_u64 = share as u64;
if share_u64 > 0 {
invoke(
&system_instruction::transfer(
&reward_pool.key(),
&holder.wallet.key(),
share_u64,
),
&[
reward_pool.to_account_info(),
holder.wallet.to_account_info(),
ctx.accounts.system_program.to_account_info(),
],
)?;
}
}
Ok(())
}
}
#[derive(Accounts)]
pub struct DistributeRewards<'info> {
#[account(mut)]
pub reward_pool: AccountInfo<'info>,
#[account()]
pub recipients: Vec<HolderInfo<'info>>,
pub system_program: Program<'info, System>,
}
#[derive(Clone)]
pub struct HolderInfo<'info> {
pub wallet: AccountInfo<'info>,
pub liv_balance: u64,
}
✅ What This Covers:
SOL rewards pulled from the reward pool
Distributed proportionally to holders based on LIV balance
Triggered manually or by an off-chain bot every 15 minutes
🧩 Part 4: Safe Wallet Donation Logic
This logic:
Monitors market cap (requires off-chain oracle or price feed)
Starts donation at $2M market cap
Routes a percentage of tax to the Safe wallet:
Starts at 35%
Increases by 6% every time market cap grows 1.5×
Caps at 95%
Delegates funds via a rotating 3-person board
🔧 Donation Trigger Logic (Rust + Anchor)
use anchor_lang::prelude::*;
#[program]
pub mod livfi_token {
use super::*;
pub fn update_donation_rate(ctx: Context<UpdateDonationRate>, market_cap: u64) -> Result<()> {
let state = &mut ctx.accounts.token_state;
// Initial trigger
if market_cap < 2_000_000 {
state.donation_rate = 0;
return Ok(());
}
// Calculate donation rate
let mut rate = 35;
let mut cap = 2_000_000;
while market_cap >= cap * 3 / 2 && rate < 95 {
rate += 6;
cap = cap * 3 / 2;
}
state.donation_rate = rate.min(95);
Ok(())
}
pub fn route_donation(ctx: Context<RouteDonation>, amount: u64) -> Result<()> {
let state = &ctx.accounts.token_state;
let donation_amount = amount * state.donation_rate / 100;
// Transfer to Safe wallet
**ctx.accounts.source.try_borrow_mut_lamports()? -= donation_amount;
**ctx.accounts.safe_wallet.try_borrow_mut_lamports()? += donation_amount;
Ok(())
}
}
#[derive(Accounts)]
pub struct UpdateDonationRate<'info> {
#[account(mut)]
pub token_state: Account<'info, TokenState>,

pub safe_wallet: AccountInfo<'info>,
pub token_state: Account<'info, TokenState>,
}
#[account]
pub struct TokenState {
pub donation_rate: u8, // 0–95%
}
✅ What This Covers:
Dynamic donation rate based on market cap
Routing funds to your multisig Safe wallet
Modular logic for off-chain market cap updates
Ready for board-controlled delegation logic
🧩 Part 5: Rotating Governance Board (Rust + Anchor)
This logic:
Maintains a list of 3 active board members
Allows rotation (manual or scheduled)
Requires multisig-like approval for fund delegation
Integrates with the Safe wallet donation logic
🔧 Governance Board Logic
use anchor_lang::prelude::*;
#[program]
pub mod livfi_token {
use super::*;
pub fn initialize_board(ctx: Context<InitializeBoard>, members: [Pubkey; 3]) -> Result<()> {
let board = &mut ctx.accounts.governance_board;
board.members = members;
board.rotation_index = 0;
Ok(())
}
pub fn rotate_board(ctx: Context<RotateBoard>, new_member: Pubkey) -> Result<()> {
let board = &mut ctx.accounts.governance_board;
board.members[board.rotation_index] = new_member;
board.rotation_index = (board.rotation_index + 1) % 3;
Ok(())
}
pub fn delegate_funds(ctx: Context<DelegateFunds>, amount: u64) -> Result<()> {
let board = &ctx.accounts.governance_board;
let signer = ctx.accounts.signer.key();
require!(
board.members.contains(&signer),
LivFiError::UnauthorizedBoardMember
);
// Transfer funds from Safe wallet to shelter
**ctx.accounts.safe_wallet.try_borrow_mut_lamports()? -= amount;
**ctx.accounts.shelter_wallet.try_borrow_mut_lamports()? += amount;
Ok(())
}

🛠️ Deployment Checklist (Solana + Anchor)
Install Anchor CLI:
cargo install --git https://github.com/coral-xyz/anchor anchor-cli --locked
Initialize Project:
anchor init livfi_token
cd livfi_token
Add Dependencies to Cargo.toml:
[dependencies]
anchor-lang = "0.29.0"
anchor-spl = "0.29.0"
Paste Modules into programs/livfi_token/src/lib.rs Combine Parts 1–5 into one file, ensuring declare_id! matches your program ID.
Build & Deploy:
anchor build
anchor deploy
Verify on Solana Explorer Use your program ID to confirm deployment and interact via Anchor client or frontend.
🔐 Notes on Security & Scaling
Use off-chain bots (e.g. cron jobs) to trigger
distribute_rewardsevery 15 minutes.Consider integrating Chainlink or Pyth for market cap feeds.
Safe wallet should be a multisig (e.g. via Squads or Safe DAO).
Governance board rotation can be automated or admin-triggered.
🧪 1. Unit Testing Suite (Anchor Framework)
CertiK will expect thorough test coverage. Let’s build tests for:
✅ Core Functions
Minting: Ensure only authorized accounts can mint
Transfers: Validate tax deductions and correct routing
Burns: Confirm tokens are removed from supply and reflected in state
Reward Claims: Test edge cases (zero rewards, max rewards, double claims)
✅ Governance & Access
Board Rotation: Validate signer updates and Safe wallet logic
Multisig Enforcement: Simulate 2-of-3 approvals for fund movement
Emergency Pauses: Add a
pause_contract()function for safety
✅ Edge Cases
Max wallet enforcement
Overflow/underflow scenarios
Invalid inputs (e.g. negative tax, zero address)
🧮 2. Overflow-Safe Math
Replace all raw arithmetic with Solana-safe methods:
rust
use anchor_lang::prelude::*;
let safe_total = total.checked_add(amount).ok_or(ErrorCode::Overflow)?;
This prevents silent overflows and is a CertiK must-have.
🔐 3. Multisig Integration (Safe Wallet)
CertiK will want to see real multisig logic, not just a placeholder. You can:
Use Squads Protocol for Solana-native multisig
Store board member pubkeys in state
Require 2-of-3 signatures for any fund movement
We can write a wrapper that checks for multisig approval before executing donate_to_shelter() or rotate_board().
📡 4. Oracle or Automation Layer
Your market cap logic and reward timing need off-chain support. Options:
TaskSolutionMarket Cap CheckUse Pyth Network for price feedsReward TriggeringUse Clockwork or Chainlink KeepersDAO Voting SnapshotIntegrate Realms or [Squads DAO]
📊 5. Event Logging
CertiK will want traceability. Add logs like:
rust
emit!(TransferEvent {
from: sender,
to: receiver,
amount: taxed_amount,
timestamp: Clock::get().unwrap().unix_timestamp,
});
Log all critical actions: transfers, burns, donations, board changes.
📋 6. Audit Checklist Document
Let’s create a LivFi_Audit_Readiness.md file with:
Contract overview
Function-by-function breakdown
Security assumptions
Governance logic
Testing coverage
External dependencies (oracles, multisig)
Known limitations
This helps CertiK auditors ramp up quickly and reduces audit time.
