# Introduction to Phoenix

> Phoenix Market is a trust-minimized P2P marketplace that allows peers to quickly and securely swap between USD and USDC without the need for KYC.

<Info>
  Phoenix is the fastest P2P marketplace for USD-USDC transactions. Because we never take custody of funds, Phoenix is the first P2P solution that allows users to quickly onramp with Zelle payments without KYC.
</Info>

Phoenix Market does not hold or transmit fiat at any point in time. Phoenix maintains a non-money transmitter status while enforcing AML compliance via Anchain.ai to prevent interaction with sanctioned funds.

## How It Works

<Steps>
  <Step title="Smart Contract Escrow">
    Sellers lock their USDC in an escrow smart contract
  </Step>

  <Step title="Payment Initiation">
    The buyer initiates a Zelle transfer through our provided webapp component
  </Step>

  <Step title="Payment Verification">
    Phoenix uses [Teller](https://teller.io) to verify that the USD payment has been made, upon which the USDC is automatically released to the buyer from escrow
  </Step>

  <Step title="Transaction Completion">
    The buyer receives their USDC in under a minute to their provided wallet address
  </Step>
</Steps>

## Payment Flows

Phoenix supports two payment flows to accommodate different user scenarios:

    ### Security & Data Protection

    Phoenix implements multiple layers of security for automated payments:

    #### Technical Security Measures

    * We establish secure mutual TLS (mTLS) connections with Teller for all banking operations
    * All API endpoints use TLS encryption for data in transit
    * Strict rate limiting and request validation prevent automated attacks
    * Each transaction uses a one-time access token generated by Teller
    * Access tokens cannot be reused, ensuring each banking session is isolated

    #### Banking Integration Security

    1. When a user initiates a payment:
       * A secure mTLS connection is established with Teller
       * The user is redirected to Teller's secure login page
       * Bank credentials are entered directly on Teller's interface
    2. During authentication:
       * The bank may require 2FA based on their security policies
       * All authentication happens directly between the user and Teller
       * Phoenix never sees or handles login credentials
  </Tab>

  <Tab title="Manual Zelle Payment">
    <div className="flex items-start gap-3">
      <div>
        <p className="text-lg font-semibold mb-2">Universal Compatibility</p>
        <p>For users without supported banks or those who encounter MFA issues, we offer a manual payment option. Users will:</p>

        <ol className="list-decimal pl-5 mt-2 space-y-1">
          <li>Open their banking app</li>
          <li>Make the Zelle payment manually to the provided recipient</li>
          <li>Return to Phoenix where we verify the payment</li>
          <li>Once verified, USDC is automatically released from escrow</li>
        </ol>
      </div>
    </div>

    <Note className="mt-4">
      For security and transaction verification, we add a unique random number of cents (between \$0.00 and \$0.20) to each transaction amount. The user will receive these addition cents in USDC. This is not a fee.
    </Note>

    ### Security & Data Protection

    Phoenix implements multiple layers of security for manual payments:

    #### Technical Security Measures

    * All API endpoints use TLS encryption for data in transit
    * Strict rate limiting and request validation prevent automated attacks
    * Payment verification is done securely through Teller

    #### Transaction Security

    1. When a user initiates a payment:
       * User is prompted to confirm the payment details

       * A unique transaction identifier is generated
    2. During verification:
       * Phoenix verifies the payment securely through Teller
       * The smart contract automatically releases USDC upon confirmation
       * All transaction data is validated before processing
  </Tab>
</Tabs>

Both payment flows maintain the same security and verification standards, ensuring safe and compliant transactions regardless of which method your users choose.

## Fraud Prevention
