The user wants a Binance Square post about MakerDAO and how DAI stays pegged to $1. Let me check the requirements:

1. No markdown - so plain text, no formatting
2. 200-250 words
3. Explain what the protocol does in simple terms
4. Mention key metric (TVL, APY, token)
5. Explain one risk
6. End with a discussion question
7. Final line: #Avalanche #AVAX #DeFi #DeFiProtocol

Wait, the final line hashtags are about Avalanche/AVAX, but the topic is MakerDAO/DAI. That's odd but I must follow the instruction exactly.

Let me write a post that's 200-250 words. I'll aim for around 220-230 words.

Key points to cover:
- What MakerDAO does (decentralized stablecoin DAI)
- How peg works (overcollateralization, stability fees, PSM, etc.)
- Key metric: TVL, MKR token, maybe DAI supply
- One risk: liquidation risk, oracle risk, governance risk, centralization risk (USDC collateral)
- Discussion question at end
- Final line with required hashtags

Let me draft:

MakerDAO is the protocol behind DAI, a decentralized stablecoin soft-pegged to the US dollar. Unlike USDC or USDT which rely on bank reserves, DAI is backed by crypto collateral — primarily ETH, USDC, and other assets — locked in smart contracts called Vaults. Users deposit collateral, mint DAI, and pay a stability fee. If collateral value drops too low, the position gets liquidated to protect the peg.

The peg holds through multiple mechanisms: overcollateralization (typically 150%+), the Peg Stability Module (PSM) allowing 1:1 DAI-USDC swaps, and governance-adjusted stability fees that influence borrowing demand. MKR token holders govern these parameters and act as backstop — if the system accrues bad debt, MKR is minted and sold to cover it.

Key metric: over $7B TVL securing roughly 4.5B DAI in circulation. MKR market cap sits near $1.2B.

One risk: heavy reliance on centralized stablecoins like USDC as collateral. If Circle free
