What to learn first

If your goal is specifically depeg and reserve risk, focus on:

1. Stablecoin type: fiat-backed, crypto-backed, algorithmic
2. Reserve composition: cash, Treasuries, commercial paper, other assets
3. Redemption mechanics: can holders redeem 1:1 quickly?
4. Liquidity risk: can reserves be sold fast without losses?
5. Counterparty risk: who holds the reserves and where?
6. Transparency: attestations vs full audits
7. Market structure: exchange liquidity, DeFi liquidity, and arbitrage

2. Read Circle’s USDC reserve disclosures
3. Read MakerDAO docs on collateral and peg stability
