| Collateralized Debt Position | DeFi | A position created by locking collateral in a contract and minting new tokens against it, which are repaid to unlock the collateral. |
| Concentrated Liquidity | DeFi | A pool design that lets a depositor commit funds only within a chosen price range, so the same money supports more trading. |
| Constant Product Formula | DeFi | The rule x times y equals k, which sets a pool's price by keeping the product of its two balances constant through every trade. |

| Liquidity Provider | DeFi | Someone who deposits assets into a pool so that others can trade against them, receiving a share of the trading fees in return. |
| Over-Collateralization | DeFi | Requiring a borrower to lock collateral worth more than the amount borrowed, so the loan stays covered if prices move. |
