Capital reserves are often funds generated and set aside from various sources, such as profit from the sale of assets, issuance of shares above their par value, or surplus from operations. These reserves are not meant for distribution as dividends but rather to strengthen the company's balance sheet and provide a buffer against potential losses. In the context of web3 and decentralized finance (DeFi), capital reserves can play a crucial role in liquidity pools where funds are locked to support trading operations, safeguard against market volatility, or provide a reserve for emergency situations.
