Flywheel overview

ELI5: Four protocols plug together so trading fees and stability fees recycle into vault yield, savings, and deeper liquidity — a closed loop instead of four isolated products.

The four pillars

Pillar	Protocol	Role in FLYWHEEL 2.0
1	TARE	Stablecoin hub — CDP, surplus, sTARE
2	Keep	Revenue accumulator — deploys USDC to strategies
3	veForge	Steers capital via gauge votes + USDC bribes
4	Coil	Fee source + batch DEX + market-making venue

Quickstart

1. Read What is DeFi? if new.
2. Study Value flow diagram.
3. Memorize invariant — scope matters (TARE engine ≠ Keep admin).
4. Walk Sepolia tour.
