当从交易或智能合约同步地址时，Moralis 会将它们标准化为小写。 这使得基于地址创建查询变得更加容易，因为它不需要创建校验和地址。 请确保在比较来自外部来源（如 ​MetaMask ​或 ​Etherscan​）的地址时，首先将其转换为小写。

// this is a checksum address (note the mixed cases)
let address = "0xEDe998b7BdE2467732b748613a1Aab4e5528dE15";

// In order to make queries based on the address you can convert it to lowercase
address = address.toLowerCase();

// Now we can use the address in our queries
const query = new Moralis.Query("EthTokenBalance");
query.equalTo("owner_of", address);
