                                            Earn Incentives

2.2 Installer Workflow

  1. Obtain payment terminals, authorization cards, and payment cards from PAYDAO-designated suppliers.
  2. Responsible for merchant acquisition.
  3. Assist merchants with the physical installation of payment terminals. Complete the initialization process and configure the Installer Reward Address.
  4. Conduct merchant training sessions to ensure they learn how to operate the system and provide troubleshooting support.
  5. Once the merchant successfully collects payments and initiates a withdrawal, the Installer Reward Address automatically receives token incentives, which can be withdrawn at any time.

2.3 Merchant Workflow

  1. Bind the designated merchant withdrawal address to the system.
  2. Learn how to operate the payment terminal and collection methods.
  3. Understand the user-side workflow, distribute payment cards to customers, and assist them with activation.
  4. Conduct daily payment collections with the flexibility to withdraw funds at any time.

2.4 User Workflow

  1. Obtain a PAYDAO Card and complete the activation process at a participating merchant location.
  2. Link the PAYDAO Card to the mobile app to monitor the stablecoin balance and token incentive balance.
  3. Deposit stablecoins into the account and complete purchases via Tap-to-Pay.
  4. After completing a transaction, the PAYDAO Card automatically earns token incentives, which are available for withdrawal at any time.

Fees and Incentives

4.1 Transaction Fees

Item Rate Description
Transaction Fee < 1% Determined by PAYDAO, adjustable via voting; automatically deducted from merchant collections.
Withdrawal Fee Free Merchants only cover the actual cost of on-chain transfers (Gas).
Top-up Fee Free No additional fees for user deposits.

4.2 Incentive Distribution (Refer to Whitepaper for details)

Role Incentive Ratio Settlement Method
User 20% Automatically calculated and distributed based on individual transaction volume.
Installer 80% Automatically calculated and distributed based on the transaction volume of all onboarded merchants.

Payment Protocol

3.1 Account System

User Payment Account

  • Each PAYDAO Card has an independent payment account (Contract Account).
  • Users deposit stablecoins to this account.
  • Deductions are made from this account during payment.
  • Private keys are stored in the PAYDAO Card, giving users full control over funds.

Merchant Collection Account

  • After initialization, the POS Terminal will create a collection account (Contract Account).
  • Each POS Terminal has its own collection account.
  • Receives stablecoins paid by users.
  • Merchants can withdraw to an external wallet address, which is unique and cannot be changed once bound.

3.2 Incentive Mechanism (Refer to Whitepaper for details)

In the PAYDAO ecosystem, transaction fees are no longer a consumption, but a redistribution of value. Through the incentive mechanism, transaction fee revenue can be directly rewarded to ecosystem builders and participants. The incentive model is designed to reward early participants to the maximum extent; the earlier the participation, the more incentive tokens are obtained.

Token Distribution Rules

  • Automatically triggered based on transactions.
  • As the overall transaction volume of PAYDAO increases, the token generation speed will halve periodically.
  • User receives: Transaction amount x Incentive token emission rate x User incentive ratio.
  • Installer receives: Merchant withdrawal amount x Incentive token emission rate x Installer incentive ratio.
  • Tokens arrive in real-time, can be viewed and withdrawn at any time.

Token Buyback Mechanism

  • PAYDAO will use transaction fee revenue to continuously buy back tokens from the secondary market and burn them, ensuring real value support for the token.

3.3 Security Mechanism

  • Contract Security: Contracts are audited by professional third parties, safe and transparent (In progress).
  • Authorization Mechanism: Payment terminals require a registered Authorization Card to function.
  • Payment Security: Although payments can be completed without a password, the payment protocol ensures payment security.
  • Withdrawal Restrictions: Only supports withdrawal to a specific merchant wallet address, which cannot be modified once bound.
  • Account Recovery: Lost payment cards support reporting loss, and users can recover via email(In progress).

System Architecture

The PAYDAO payment system adopts a decentralized architecture. Its core consists of the payment protocol, payment terminals, payment cards, and supporting application software.
