The problem useprysm solves

The Core Problem
Most people don't donate to public goods because they fear losing capital. Traditional donations are one-time events where you give away money forever. This psychological barrier prevents 98% of DeFi users from supporting the ecosystem they benefit from.

What usePrysm Does

For Users:
usePrysm lets you support public goods WITHOUT losing your principal. Deposit $10,000 into our Octant V2 strategy, and:

✅ Your $10,000 stays yours (withdraw anytime)
✅ You earn 80% of yields (3.2% APY compounding)
✅ Public goods get 20% of yields ($80/year) FOREVER
✅ Zero manual work after initial deposit

It's like a university endowment - the principal generates perpetual funding for important causes.

For Public Goods Projects:
Instead of quarterly grant applications, projects receive predictable monthly income from DeFi yields. A $10M vault generates $80K/year for public goods automatically.
For Octant V2 Ecosystem:
usePrysm is a production-ready Yearn v3 strategy that demonstrates how to:

Integrate multiple yield protocols (Aave, Morpho)
Implement programmatic yield allocation policies
Create sustainable funding mechanisms
Build user-friendly DeFi experiences

✅ Simple dashboard shows everything

Real Impact Example
Emma's Story:

Deposits: $10,000 USDC
Year 1: Earns $320 (keeps it) + $80 donated → Funded Ethereum RPC node
Year 2: Earns $330 (keeps it) + $83 donated → Funded developer tools
Year 5: Earns $368 (keeps it) + $92 donated → Funded security audit

Total after 5 years:

Emma's balance: $11,698 (grew 17%)
Public goods funded: $428
Emma's effort: 5 minutes (initial deposit)

Challenges I ran into

Challenge 1: Understanding Yearn v3 Strategy Pattern in 3 days
The Issue:
I had only 3 days total and needed to understand Yearn v3's BaseTokenizedStrategy inheritance model. The documentation is comprehensive but dense - it took me 45 minutes just to understand the mandatory overrides.
What I Learned:
Yearn v3 strategies MUST implement:

_deployFunds(uint256) - Where to put user deposits
_freeFunds(uint256) - How to withdraw from protocols
_harvestAndReport() - Collect yields and report gains/losses

Challenge 2: Implementing 80/20 Yield Split Logic
The Bug:
Initial implementation split TOTAL ASSETS (principal + yield), not just yield

Challenge 3: Simplified Aave Integration (No Time for ATokenVault)
The Reality:
Full Aave ATokenVault integration requires understanding their vault wrapper, which would take 2+ hours. I had 30 minutes for Aave integration.
