Abstract

The Bond module enables transparent on-chain fundraising via predefined contract logic, supporting:

• Structured token distribution
• Vesting schedules
• Sustainable liquidity formation

Disclaimer: Bond purchases involve risk. Token values may fluctuate during vesting periods. This document is for informational purposes only.

1. Overview

Zetarium Bond System (Vesting Sale Platform) enables projects to conduct token sales with built-in linear vesting. Users purchase tokens at a discount, and tokens are released gradually over a specified vesting period after the sale ends. The platform is designed with security, transparency, and user experience as core principles.

3. How Bonds Work — Simple Explanation

3.1 Buy at a Discount

                                                                 
   1. BUY              2. WAIT            3. CLAIM             
                   
   Purchase tokens    Tokens unlock      Collect your           
   at a discount      over time          vested tokens          
                                                                 
   "I buy $1000       "5% unlocks        "I claim tokens        
    worth at 10%       each week"         as they unlock"       
    discount"                                                    
                                                                 

3.2 Real Example

Info In Simple Terms: Bonds let you buy tokens at a lower price than the market — like getting a VIP discount. The catch? Your tokens unlock gradually over time (vesting), which protects everyone from sudden price crashes.

4. Getting Started

5. Frequently Asked Questions (FAQ)

5.1 General Questions

Is Zetarium Bond System safe to use?

Yes! Zetarium smart contracts are built with industry-leading security practices:

• ReentrancyGuard prevents attack vectors
• Quote Signature Verification ensures fair pricing
• Tokens locked in contract not held by project team
• All code is open-source and verifiable on-chain

5.2 Buying Questions

What is vesting and why does it exist?

Vesting means your tokens unlock gradually over time instead of all at once. This:

• Protects against price dumps from large instant sells
• Shows the project's commitment to long-term growth
• Gives you steady access to your tokens over the vesting period

What if the project fails during vesting?

Your purchased tokens are locked in the smart contract, not held by the project. Even if the project team disappears, you can still claim your vested tokens directly from the contract.

Can I sell my vested position?

The vesting position is tied to your wallet address and cannot be transferred. However, once tokens are claimed (vested), they're regular tokens you can freely trade.

How is the discount calculated?

If a token is worth $1.00 on the market and the bond offers 10% discount:

• You pay: $0.90 per token
• You get: $1.00 worth of tokens
• Your profit: $0.10 per token (if price stays the same)

Formula: Price = Market Price × (1 - Discount%)

5.3 Project Owner Questions

When can I withdraw the raised funds?

You can withdraw proceeds after the sale ends. The platform deducts a 1% fee:

• Net Proceeds = Total Raised - (Total Raised × 1%)

What happens to unsold tokens?

After the sale ends, you can withdraw any unsold tokens back to your wallet. They are not locked forever.

6. Technical Details

6.1 Architecture

The Bond System implements a Factory-Sale architecture that allows any project to create customizable token sales with vesting.

                 VESTING SALE PLATFORM (Factory)

6.4 Vesting Mechanism

Linear Time-Based Vesting

Vested Amount = (Total Purchased × Elapsed Time) / Vesting Duration

Example Timeline:

Sale Ends  Vesting Ends
                                                       
     25% elapsed  25% vested                     
     50% elapsed  50% vested                     
     75% elapsed  75% vested                     
     100% elapsed  100% vested 

6.5 Quote-Based Purchases

All purchases require a backend-signed quote to ensure:

• Fair market pricing at the time of purchase
• Prevention of front-running attacks
• Cross-chain replay protection via chain ID inclusion

Quote Signature Structure:

keccak256(
    chainId,
    saleAddress,
    buyerAddress,
    paymentToken,
    paymentAmount,
    tokensOut,
    deadline,
    nonce
)

7. Security Features

Warning Your Funds Are Protected: Every Zetarium contract is designed with multiple security layers. Tokens are locked in the smart contract, not held by the project team.

7.1 Smart Contract Security

7.2 Signature Security

The platform implements signature verification using:

• EIP-191 Ethereum Signed Message prefix
• Chain ID inclusion for cross-chain replay protection
• Sequential nonces to prevent transaction replay
• Deadline enforcement for quote expiration

7.3 Buyer Protection

8. Fee Structure

Withdrawal Formula

Net Proceeds = Total Raised - (Total Raised × 1%)
Platform Fee = Total Raised × 1%

Example:

• Total Raised: $100,000
• Platform Fee: $1,000 (1%)
• Net Proceeds: $99,000
