Automated Investing

Auto-Investment

Enable seamless music discovery with automated payments. Listen without interruption while staying in full control of your budget.

What is Auto-Investment?

Auto-Investment is a frictionless payment system that allows you to discover and stream music without signing a transaction for every song. Set your budget once, and the platform handles micropayments automatically as you listen.

This feature transforms the music streaming experience by removing payment friction while maintaining full transparency and control over your spending.

Frictionless

Stream continuously without transaction prompts

Secure

Session keys with spending limits protect your wallet

Budget Control

Set daily and per-track spending limits

How It Works

1
Set Your Budget

Configure your auto-investment settings with daily spending limits and per-track maximums. You have complete control over how much you spend.

Daily Limit:$10.00 USDC

Per Track Limit:$1.00 USDC

Session Duration:24 hours

2
Create Session Key

When you activate auto-investment, a temporary session key is generated. This key has limited authority to spend only up to your configured limits and expires after 24 hours.

Your main wallet private key never leaves your device. The session key is stored securely and can only execute pre-authorized actions.

3
Stream Music Freely

Discover and play music without interruption. The platform automatically handles X402 micropayments using your session key, staying within your spending limits.

✓ Playing "Midnight Dreams" - Artist Name
  Payment: $0.015 USDC (auto-paid)
  
✓ Playing "Electric Soul" - Another Artist
  Payment: $0.02 USDC (auto-paid)
  
✓ Daily spending: $2.45 / $10.00 remaining

4
Monitor & Revoke Anytime

Track your spending in real-time and revoke your session key at any moment. Sessions automatically expire after 24 hours for added security.

Full transparency: View every micro-transaction in your activity history.

Technical Architecture

Session Key System

Auto-investment uses a secure session key architecture built on top of EIP-3009 (transferWithAuthorization). This enables gasless, pre-authorized USDC transfers without exposing your main wallet.

interface SessionKey {
  user_address: string        // Your wallet address
  session_key: string          // Temporary private key
  spending_limit: number       // Max daily spend
  spent_amount: number         // Current spending
  max_per_transaction: number  // Per-track limit
  valid_until: timestamp       // 24h expiry
  is_active: boolean          // Revocation status
}

Platform Impact

For Listeners

Auto-investment removes the friction of micropayments, making it as easy to discover new music on MyUSIC as it is on traditional streaming platforms—but with the added benefit of directly supporting artists.

Uninterrupted listening experience
Discover new artists without commitment
Full control over budget and spending
Transparent payment tracking

For Artists

By reducing payment friction, auto-investment increases the likelihood that listeners will stream your tracks. More streams mean more revenue, even with custom per-stream pricing as low as fractions of a cent.

Higher conversion rates from discovery to streams
Instant payment settlement on-chain
Listeners more likely to try new tracks
Better user experience = more engagement

Platform Growth

Auto-investment makes MyUSIC competitive with Web2 streaming platforms while maintaining Web3 benefits like artist ownership and fair compensation.

Lowers barrier to entry for new users
Bridges Web2 UX with Web3 economics
Increases platform stickiness and retention
Drives more transaction volume through protocol

Best Practices

Recommended Settings

• Set daily limits based on your listening habits
• Start with $5-10 daily for casual listening
• Per-track limit of $0.50-1.00 is reasonable
• Enable "Auto-unlock full songs" for favorites
• Review spending weekly to adjust limits

Safety Tips

• Never set limits higher than you can afford
• Revoke sessions when not actively using platform
• Monitor spending regularly in dashboard
• Sessions auto-expire after 24 hours
• Can revoke instantly if needed

Integration with X402

Auto-investment works seamlessly with the X402 micropayment protocol. When you stream a track, the session key authorizes X402 chunk payments automatically without requiring wallet signatures.

Combined Workflow:

User activates auto-investment session
User plays a track with custom artist pricing
X402 protocol streams audio in 30-second chunks
Session key auto-authorizes each chunk payment
Payments settle on-chain via EIP-3009
Artist receives revenue instantly
