• Soft liquidation = collateral is progressively swapped rather than instant liquidation
• Borrowing happens through Curve lending controllers (per-market contracts)
• Supported collateral includes ETH, wstETH, sfrxETH, tBTC, wBTC
• crvUSD has a peg keeper mechanism to maintain $1 peg via Curve pools
