According to CoinMeta, Lido has announced the launch of an automated LDO repurchase mechanism for NEST, with an annual repurchase cap of 10 million US dollars. When the DAO collateral income exceeds the benchmark of 40 million US dollars, 50% of the surplus will be automatically used to buy LDO through Cow Swap. If the income falls below the benchmark, the shortfall must be made up by subsequent surpluses, with a daily purchase limit of 50,000 US dollars. The LDO purchased will belong to DAO.
