Crypto Cho Người Mới / Mô phỏng / MakerDAO Vault + DSR
Simulator MakerDAO Vault + DSR
MakerDAO là protocol đằng sau DAI — largest decentralized stablecoin và một trong DeFi foundational primitive. Bạn có thể: (1) Lock collateral (ETH, WBTC, USDC, real-world bond), borrow DAI against it, pay stability fee trên debt. (2) Hold DAI trong DSR module earn interest funded by stability fee + RWA bond yield. Simulator này chạy both side — vault metric, liquidation price, borrow-and-deposit carry trade. Maker RWA strategy (tokenized US Treasury) là sao DSR offer được 8-12% APR while remaining decentralized.

✗ Unprofitable — DSR rate below stability fee
Vault basic — collateral, debt, stability fee
Maker vault là smart contract hold collateral bạn và track DAI debt bạn. 'Liquidation price' của simulator là critical metric: khi collateral price bạn fall về value này, vault bạn automatically liquidated. Example: 10 ETH ở $3500 = $35,000 collateral. Bạn mint $15,000 DAI. Liquidation ratio 145% (collateral / debt ≥ 1.45). Liquidation price = $15,000 × 1.45 / 10 = $2,175. Nếu ETH drop dưới $2,175, vault bạn get liquidated, bạn lose 13% penalty. Healthy vault maintain LTV well below 50%.
DSR — DAI Savings Rate work sao
DSR là module nơi bạn deposit DAI và earn interest. Interest rate set bởi Maker governance dựa protocol revenue. Currently funded by: (1) Stability fee từ vault (e.g., 10% trên $1B ETH vault = $100M/year). (2) RWA bond (Maker hold $1B+ tokenized US Treasury earning 4-5%, contribute $50M+/year). (3) PSM module fee. Total revenue distributed cho DSR depositor (sau operational cost). DSR APR varies — 5% trong 2023, 15% đầu 2024, ~10% trong 2024. Mechanism structurally similar money-market fund.
Carry trade — borrow DAI, deposit trong DSR
Khi DSR > stability fee, bạn profit by borrow DAI từ vault và deposit vào DSR. Example: ETH vault ở 10% SF, DSR ở 12%. Net = 2% APR trên debt bạn. Với $100k debt, đó $2,000/year free money (minus gas). Catch: bạn dùng leverage. Nếu ETH price drop, vault bạn liquidated được even though carry profitable. Carry trade work best với LST collateral (stETH earn staking yield while bạn borrow against it). Always maintain buffer trên liquidation price.
Sao MakerDAO matter hơn size suggest
MakerDAO là $5B protocol, much smaller hơn centralized stablecoin ($150B+ combined). Nhưng nó pioneered: (1) Crypto-collateralized stablecoin — original DAI model. (2) On-chain treasury management — Maker hold $5B trong diversified asset, governed entirely bởi token voter. (3) Real-World Asset integration — first major DeFi protocol hold tokenized real asset at scale. (4) Decentralized governance evolution — Endgame plan split Maker thành subDAOs. Even though USDC larger, MakerDAO design influence mọi modern stablecoin attempt.
Câu hỏi thường gặp
+Khác nhau giữa DAI, USDS, và Sky là gì?
Same protocol, evolving brand. Original launch (2017): MKR governance token, DAI stablecoin. 2024 rebrand: SKY governance token (1 MKR = 24,000 SKY), USDS stablecoin (functionally equivalent DAI, 1:1 redeemable). Brand pivot driven bởi Endgame plan evolve protocol thành modular subDAOs. DAI still exists và works (1:1 với USDS) — đa số user chưa migrated và probably won't unless họ want SKY governance. Cho practical purpose, DAI = USDS.
+Sao DSR offer high yield so với centralized saving?
Vì DSR capture yield từ multiple source: (1) Vault stability fee (người pay borrow DAI, bạn earn). (2) RWA bond (tokenized US Treasury earning risk-free rate). (3) PSM trading fee. Together fund được 10-15% APR distribution. Compare bank savings account: bank borrow ở 0% từ depositor, lend ở 8-10%, keep spread. DSR cut out bank middleman và give spread cho depositor. Price: bạn trusting Maker governance + smart contract thay vì bank FDIC insurance.
+MakerDAO có collapse như UST/LUNA không?
Unlikely — different mechanism. UST algorithmic (no real backing, depend on LUNA market cap). DAI OVER-COLLATERALIZED — mỗi $1 DAI backed by $1.45+ collateral. Trong market crash, vault get liquidated; nếu liquidation happen too fast, MKR minted và sold recapitalize system (đã happen 3/2020 Black Thursday). Mechanism survived multiple stress test. Real risk: (1) Smart contract bug. (2) Oracle manipulation. (3) Governance attack trên MKR. (4) USDC depeg (Maker hold significant USDC). Not impossible fail, nhưng much more resilient hơn UST.
+Tôi dùng Maker vault hay borrow từ Aave?
Depend rate environment và use case. Maker pros: very battle-tested, no liquidator priority queue (bạn có time), RWA collateral option. Aave pros: more collateral type, variable rate (sometimes cheaper), better UX, borrow other token được không just stable. Đa số institutional user prefer Maker cho large position do conservative liquidation mechanic. Retail user often prefer Aave cho UX. Cho DAI specifically, Maker often có cheapest stability fee trong DeFi (sometimes 0% cho USDC-backed via PSM).
+PSM (Peg Stability Module) là gì?
PSM là special Maker module swap DAI ↔ USDC ở exactly 1:1 với zero slippage. Tồn tại maintain DAI peg — nếu DAI trade trên $1, arbitrageur deposit USDC vào PSM, mint DAI, sell trên market. Nếu dưới $1, mua DAI rẻ, redeem PSM cho USDC. As side effect, ~30-50% DAI backing giờ USDC. Đây sometimes-controversial centralization risk (nếu USDC depegged, DAI sẽ có problem), nhưng đã key cho maintaining tight peg through volatile period.
