地址(1)在实心中是什么？

Question

最近，我读到了复合金融的智能合约。在PriceOracleProxy.sol(https://etherscan.io/address/0xe7664229833AE4Abf4E269b8F23a86B657E2338D#code)中

第3863行显示：

地址常量usdcOracleKey = address(1)；我混淆了这个地址(1)，它是什么意思。

/**
 * @notice address of the cUSDC contract, which we hand pick a key for
 */
address public cUsdcAddress;

/**
 * @notice address of the USDC contract, which we hand pick a key for
 */
address constant usdcOracleKey = address(1);


last used:
     return v1PriceOracle.assetPrices(usdcOracleKey);

这只是另一种写入0x0000000000000000000000000000000000000001的方式，通过相同的逻辑地址(0)是0x0000000000000000000000000000000000000000
