+The `defaultReturnFormat` allows users to specify the format in which certain types of data should be returned by default. It is a configuration parameter that can be set at the global level and affects how data is returned across the entire library.
+```ts

+web3.defaultReturnFormat = {
+    number: FMT_NUMBER.BIGINT,
+    bytes: FMT_BYTES.HEX,
+};
+
+```
+:::info
+The `defaultReturnFormat` can be configured both globally and at the package level:
+```ts
+import { Web3Eth, FMT_NUMBER, FMT_BYTES } from 'web3-eth';
+
+const eth = new Web3Eth()
+eth.defaultReturnFormat = {
+    number: FMT_NUMBER.BIGINT,

+    NUMBER = 'NUMBER_NUMBER',
+    HEX = 'NUMBER_HEX',
+    STR = 'NUMBER_STR',
+    BIGINT = 'NUMBER_BIGINT',

+:::warning
+In version 4.x, all numbers return as BigInt instead of string or number, which constitutes a breaking change for users accustomed to handling numbers as string or number in their code. For instance, web3.eth.getBalance will now return BigInt instead of string or number. If you wish to retain numbers as number or string, you can refer to [this guide](/guides/web3_config/#defaultreturnformat) on how to set returning types in web3js 4.x.
