Liquidity Provider Guide

Welcome to Phoenix, a trustless P2P marketplace for USD-USDC transactions. This documentation guides Liquidity Providers (LPs) through our platform, helping you understand how to provide liquidity and earn returns.

Overview

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 with no KYC. By operating outside the flow of funds similar to DEXs like Uniswap, Phoenix maintains a non-money transmitter status while still enforcing AML compliance via Anchain.ai to prevent interaction with sanctioned funds.

  • Set your own price (recommended spread is 100 bps)
  • Keep full control of your assets
  • Withdraw your USDC from your liquidity pool at any time before it's purchased
  • Receive USD payments directly to your bank account via Zelle
  • Pay zero fees - Phoenix charges no fees to LPs

By providing liquidity, you can capitalize on a spread (~100 bps at launch) on every transaction while maintaining complete control of your assets. Our API will allow you to programmatically manage your liquidity pool, set custom spread parameters, monitor transactions in real-time, and automatically reinvest profits. This automation reduces operational costs and enables your capital to cycle multiple times per day, significantly amplifying your effective returns compared to traditional yield products.

Trust & Backing

Phoenix is a product created by Suave, and is backed by leading investors in the Web3 space.

How It Works

Phoenix operates with a straightforward yet powerful workflow:

1

Provide Liquidity

Deposit USDC into your Phoenix liquidity pool and set your desired spread.

2

Automated Order Matching

Buyers purchase USDC and send USD directly to your bank account via Zelle.

3

Payment Verification

Phoenix uses Teller to verify the USD payment has settled in your account.

4

USDC Release

Once payment is confirmed, USDC is released from your liquidity pool to the buyer. Capital is now ready for the next cycle.

Key Security Features

  • Your USDC remains in your liquidity pool until payment confirmation
  • You can withdraw unmatched USDC at any time
  • Payment confirmation using Teller's secure verification system

Note: Actual returns may vary based on market conditions, transaction timing, and other factors. This calculator provides estimates only.

Sample Return Calculation

JavaScript
// Sample calculation parameters
const initialCapital = 50000; // USDC
const spread = 0.01; // 100 bps = 1%
const phoenixTxTime = 2; // minutes
const repurchaseTime = 30; // minutes
const totalCycleTime = phoenixTxTime + repurchaseTime;
const dailyVolume = 1000000; // $1M

// Maximum cycles based on time and volume constraints
const maxCyclesPerDay = Math.min(
  Math.floor(1440 / totalCycleTime), // Time constraint (1440 min/day)
  Math.floor(dailyVolume / initialCapital) // Volume constraint
);
// Result: 45 cycles per day

// Calculate profit with compound returns and fees
const phoenixGasFee = 0.05; // $0.05 per transaction
const usdcPurchaseFee = 0.10; // $0.10 fixed fee per purchase
const usdcPurchasePercentFee = 0.00; // 0% percentage fee
const transactionFee = phoenixGasFee + usdcPurchaseFee + (usdcPurchasePercentFee / 100) * initialCapital; // $0.15 total fee per cycle
const grossProfit = ((Math.pow(1 + spread, maxCyclesPerDay) - 1) * initialCapital);
const totalFees = transactionFee * maxCyclesPerDay;
const netProfit = grossProfit - totalFees;

// Calculate daily return percentage
const dailyReturn = (netProfit / initialCapital) * 100;

// Result: ~25% daily return when compounded over 45 cycles

Frequently Asked Questions

Is my USDC safe in the smart contract?

Yes. Our smart contract is open source and allows you to withdraw your USDC at any time until it's matched with a buyer. Your assets remain under your control through our non-custodial design.

How do you verify payments?

Phoenix uses Teller's payment verification system to confirm that USD has settled in your account before releasing USDC from your liquidity pool to the buyer.

What are the minimum/maximum capital requirements?

There are no minimum or maximum capital requirements. You can start with any amount and scale as you see fit.

How does Phoenix make money if there are no LP fees?

Phoenix charges businesses for using our API to onramp their users. This B2B model allows us to keep the platform free for liquidity providers.

What KYC/AML requirements are there for LPs?

No KYC is required for liquidity providers on Phoenix. Since we operate as a non-custodial protocol and never take custody of your funds, Phoenix itself is not a money transmitter.

The Phoenix smart contract holds USDC until conditions are met, and USD payments go directly to your bank account. This decentralized approach means we don't need to implement traditional KYC processes that centralized exchanges require.

However, we recommend consulting with your legal advisors regarding your specific jurisdiction's requirements for P2P trading activities.
