The problem GIVE Protocol solves

The Problem

Donating to charity means losing your money forever. You can't support causes without sacrificing your savings.

The Solution

GIVE Protocol uses DeFi yield to fund charities while your principal stays safe. Stake stablecoins or ETH, yield goes to NGOs, withdraw your deposit once lock-in period finishes.

For Donors:

• Fund causes without losing your capital
• Vote on milestones to ensure accountability
• Withdraw instantly if recipient deviate from their milestones

For NGOs:

• Sustainable recurring funding from staking yield
• Built-in accountability through on-chain governance
• Access crypto funding without asking for permanent donations

Why It's Better:

• Get your money back anytime
• Smart contracts enforce accountability
• Yield flows as long as you stay staked
• No central authority can misuse funds

Challenges we ran into

The Problem:
DeFi protocols generate yield in completely different ways.

As an example: Aave increases your aToken balance over time. Pendle has fixed maturity tokens. sUSDe auto-compounds into the token itself. Some protocols queue yield that you claim separately. We needed one vault system to handle all of them.

The Solution:
We created 5 adapter types with a unified IYieldAdapter interface:

• BalanceGrowth (Aave): Tracks liquidity index, balance grows automatically
• CompoundingValue (stETH, sUSDe): Token value increases, not balance
• FixedMaturityToken (Pendle): Principal tokens with maturity dates, rollover logic
• ClaimableYield: Yield queued separately, claim then distribute
• Manual: Off-chain management with on-chain attestation

Each adapter translates protocol-specific yield into a common harvest() function. The vault doesn't care how yield is generated—it just calls adapter.harvest() and receives profit/loss.
