YieldFarmPayment Skill v1.0

Important Security Notice

This skill requires the user to provide a raw PRIVATE_KEY in the .env file. This grants full control of the wallet to the skill.

Strongly recommended:

Use a dedicated wallet created only for this skill

Fund it with only the necessary amount + small buffer for gas

Never use your main wallet or a wallet containing significant funds

Environment variables required:

PRIVATE_KEY: Private key of dedicated wallet

BASE_RPC_URL: Base Mainnet RPC URL

DeFi Immediate Payment System with Capital Recovery via Aave V3

Pay recipients immediately on Base network, then recover your capital over time through Aave V3 yield farming.

⚠️ v1.0 — Upfront Mode Only

v1.0 supports only Upfront Mode (immediate payment to recipient). Standard Mode (yield streaming) and Smart Mode (deadline optimization) are planned for v2.0 with x402 protocol integration.

🎯 Features

Upfront Mode: Immediate USDC payment to recipient + capital recovery via yield

Flexible Collateral: 3x to 20x multiplier with configurable buffer (default: 20x)

Aave V3 Integration: Deposit collateral to earn yield on Base network

Robust Transaction Handling: Automatic retry, gas optimization, error recovery

Professional CLI: Full-featured command line interface

💰 Monetization & Usage

Model: Free.

Cost: 0 USDC per execution.

Network: Base Mainnet.

💰 How It Works (Upfront Mode)

Payment Flow:

1. Calculate total collateral: payment × multiplier × (1 + buffer%) 2. Transfer payment immediately to recipient (seller gets paid NOW) 3. Deposit remaining collateral in Aave V3 4. Yield accumulates on deposited collateral 5. Buyer recovers the payment amount over time via yield

Recovery Time Calculation:

The amount to recover is the PAYMENT (sent to seller), NOT the total collateral.

Recovery Time = Payment Amount / Annual Yield from Aave Deposit

Example: 0.1 USDC payment, 20x collateral, 8% buffer, 3% APY

Total Locked:      0.1 × 20 × 1.08 = 2.16 USDC
Immediate Payment: 0.1 USDC → sent to recipient
Aave Deposit:      2.16 - 0.1 = 2.06 USDC
Aave example APY   ~3% 
Annual Yield:      2.06 × 3% = 0.0618 USDC/year
Amount to Recover: 0.1 USDC (the payment, NOT the collateral)
Recovery Time:     0.1 / 0.0618 ≈ 592 days (~1.6 years)

Why Higher Collateral = Faster Recovery:

| Multiplier | Aave Deposit | Annual Yield | Recovery Time | |------------|-------------|--------------|---------------| | 3× | 0.224 USDC | 0.0067 USDC | ~15 years | | 5× | 0.440 USDC | 0.0132 USDC | ~7.5 years | | 10× | 0.980 USDC | 0.0294 USDC | ~3.4 years | | 20× | 2.060 USDC | 0.0618 USDC | ~1.6 years |

More collateral deposited in Aave → more yield generated → faster recovery of the payment amount.

🚀 Quick Start

Prerequisites

Node.js 18+

Base network wallet with ETH for gas

USDC tokens for collateral

Installation

cd your-project
npm install viem dotenv

Configuration

1. Copy .env.example to .env 2. Set your PRIVATE_KEY and BASE_RPC_URL 3. Verify contract addresses for Base network

Usage

# Check configuration
node scripts/check-configuration.js
Safe simulation testing (no transactions)
node scripts/test-realistic-payment.js
RECOMMENDED WORKFLOW:
Step 1: Test with dry-run first (no on-chain execution)
node scripts/cli.js --dry-run --amount 0.1 --recipient 0x... --collateral 5 --buffer 8
Step 2: Execute real transaction with interactive confirmation
node scripts/cli.js --amount 0.1 --recipient 0x... --collateral 5 --buffer 8
Advanced: Skip confirmation after thorough review (use with caution)
node scripts/cli.js --confirm --amount 0.1 --recipient 0x... --collateral 5 --buffer 8
Custom collateral multiplier
node scripts/cli.js --mode upfront --amount 0.5 --recipient 0x... --collateral 10 --buffer 5

Dual Confirmation on Mainnet: Two separate confirmations required for mainnet transactions

Address Validation: Verifies recipient and wallet addresses before execution

CLI Safety Flags

# Test with dry-run first (RECOMMENDED)
node scripts/cli.js --dry-run --amount 0.1 --recipient 0x...
Real transaction with interactive confirmation (default)
node scripts/cli.js --amount 0.1 --recipient 0x...
Skip confirmation only after thorough review (use with caution)
node scripts/cli.js --confirm --amount 0.1 --recipient 0x...

Risk Management

Collateral Buffer: 5-15% safety margin

APY Estimation: Conservative 3% default

Multiplier Limits: 3x minimum, 20x maximum

🚨 Error Handling

Common Errors & Solutions

"replacement transaction underpriced": Automatic retry with increased gas

"insufficient funds": Balance verification before transaction

"nonce too low": Automatic nonce management

Contract errors: Detailed logging and fallback

📈 Roadmap

v2.0 Planned Features

Standard Mode: Yield streaming via x402 protocol

Smart Mode: Deadline optimization

x402 Integration: Trustless automatic yield distribution to sellers
