| * deploys all oracle related contracts from scratch for ease of debugging. | ||
| * | ||
| * @dev Ubiquity protocol supports 2 oracles: | ||
| * 1. Curve's Dollar-3CRVLP metapool to fetch Dollar prices | ||
| * 2. Chainlink's price feed (used in UbiquityPool) to fetch collateral token prices in USD | ||
| * | ||
| * There are 2 migrations (deployment scripts): | ||
| * 1. Development (for usage in testnet and local anvil instance forked from mainnet) | ||
| * 2. Mainnet (for production usage in mainnet) | ||
| * | ||
| * Mainnet (i.e. production) migration uses already deployed contracts for: | ||
| * - Chainlink price feed contract | ||
| * - 3CRVLP ERC20 token | ||
| * - Curve's Dollar-3CRVLP metapool contract | ||
