White Paper v1.0

Keyper

Decentralized Platform for Secure IP Address Transactions

February 2026 • 🇨🇭 Swiss Development

01 Vision & Mission

“Making IP address trading as simple, fast, and secure as buying a product on a marketplace”

Keyper is the first decentralized platform for secure IPv4 address block transactions, leveraging blockchain technology and smart contracts to eliminate the need for intermediaries while ensuring guarantees for both parties.

Our mission is to transform the archaic IP address market, reducing transaction time from weeks to minutes, eliminating fraud risks, and cutting transaction costs by an order of magnitude.

02 Market Problem

IPv4 Address Scarcity

The IPv4 address pool has been officially exhausted since 2019. Yet demand continues to grow: cloud services, IoT devices, data centers — all require IP addresses. This has turned IPv4 addresses into a valuable digital asset.

Market Prices (2026)

• 1 IP address: $30–60
• /24 block (256 IPs): $7,000–15,000
• /16 block (65,536 IPs): $1.5–3M

Market Size

• Global market: $1.5B+ per year
• Annual transactions: 10,000+
• Broker fees: 5–15%

Pain Points of the Current Process

🕐

Slow Timelines

Deals take 2–8 weeks: negotiations, verifications, registry applications, waiting for WHOIS updates

🔓

Trust Risks

Buyer pays upfront and waits weeks without guarantees. Seller risks not receiving payment

🕵️

Fraud

Selling stolen blocks, forged ownership documents, double-selling the same block

💸

High Fees

Brokers charge 5–15% of deal value. On a /16 block sale — that's hundreds of thousands of dollars

03 Our Solution

Keyper — Smart Contract as Intermediary

We replace brokers and middlemen with a smart contract on the Polygon blockchain. Buyer's funds are locked in the contract and automatically transferred to the seller only after confirmed IP block transfer in the RIPE registry.

⚡

Speed

Deal closes automatically once Oracle confirms the transfer in RIPE

🔒

Security

Funds in escrow until confirmation. Automatic refund on deadline expiry

💰

Savings

Platform fee of 1–2% instead of 5–15% from traditional brokers

Key Advantages

✓Trustless: No need to trust the counterparty — smart contract guarantees execution
✓Transparency: All deals are recorded on blockchain and publicly verifiable
✓Automation: Oracle checks RIPE API every minute and closes deals automatically
✓Fraud Protection: ASN ownership verification at deal creation
✓Global Access: Participants from any country, cryptocurrency settlements

Smart Contract Architecture

contract IPEscrow v4.3 {
    struct Deal {
        address seller;       // Seller wallet
        address buyer;        // Buyer wallet
        string ipBlock;       // e.g. "195.20.115.0/24"
        string buyerASN;      // Buyer ASN (RIPE)
        uint256 price;        // Price in USDT (ERC-20)
        DealStatus status;    // Created → Funded → Completed
        uint256 deadline;     // Refund deadline (30 days)
    }
    
    // Multisig 2-of-3: Oracle + Buyer + Broker
    createDeal()      // Seller creates a deal
    fundDeal()        // Buyer pays USDT (funds in escrow)
    confirmTransfer() // 2 of 3 confirm → 99% to seller, 1% platform fee
    refund()          // Buyer refund on deadline expiry

    // Contract: 0xb02b5075...5d92 (Polygon Mainnet, v4.3)
    // Audited by ChainGPT — all findings addressed
}

Oracle Mechanism

The Oracle is a service that bridges blockchain with the real world. Our Oracle:

Seller specifies the exact IP block when creating a deal (e.g., 195.20.115.0/24)
Upon deal funding, saves a snapshot of the buyer's current prefixes
Every 60 seconds queries the RIPE API for current data
Compares current prefixes with the snapshot
If the buyer has acquired the specified IP block — calls confirmTransfer()
Smart contract automatically transfers funds to the seller

05 How It Works

Seller Creates a Deal

Specifies the IP block (e.g., 195.20.115.0/24), their ASN, buyer's ASN, and price in POL. The system verifies block ownership via the RIPE API.

Buyer Funds the Escrow

Buyer connects MetaMask, reviews deal terms, and sends POL to the smart contract. Funds are locked until deal completion.

IP Transfer in Registry

Seller initiates the IP block transfer through the RIPE NCC portal. This is a standard procedure taking from several hours to several days.

Automatic Completion

Oracle detects that the IP block has appeared in the buyer's resource list in RIPE. Smart contract automatically transfers funds to the seller. Deal complete!

Party Protection

For the Buyer:

If the transfer doesn't occur within 30 days — automatic refund to the buyer's wallet

For the Seller:

Funds are guaranteed to be paid immediately after Oracle confirms the transfer
