Why MakaPay?

The Problem

Accepting crypto payments across multiple blockchains is expensive and complex:

• Gas Management Nightmare: Each blockchain requires its own native token for gas (ETH, MATIC, BNB)

• Idle Capital: Merchants must maintain gas balances on every chain they support

• Cost: Managing gas across 4+ chains can cost ~$95/month in idle capital and gas fees

• Complexity: Different wallets, different tokens, different processes per chain

The Solution

MakaPay introduces a unified gas management system:

• Single Gas Balance: Deposit USDT once to your Gas Tank on MakaChain

• Multi-Chain Acceptance: Accept payments on Ethereum, Polygon, BSC, and more

• Reduced Costs: Cut gas management costs to ~$30/month

• Zero Complexity: No need to manage native tokens on payment chains

How It Works

┌─────────────────────────────────────────┐
│        MakaChain (Gas Hub)              │
│   Your Gas Tank Balance (USDT)          │
└─────────────────────────────────────────┘
              ↓           ↓           ↓
    ┌─────────────┐ ┌─────────────┐ ┌─────────────┐
    │  Ethereum   │ │   Polygon   │ │     BSC     │
    │  Payments   │ │  Payments   │ │  Payments   │
    └─────────────┘ └─────────────┘ └─────────────┘

1. Merchant creates a payment link specifying amount, token, and network

2. Customer pays to a deterministic smart contract address

3. MakaPay settles the payment, deducting gas from your Gas Tank

4. Merchant receives the full payment amount
