Suggested change
Interoperable address format applicable to solidity type `bytes` (especially `bytes32`) and `uint256`.
Interoperable address format applicable to solidity type `bytes`.

It's not actually related to bytes32 and uint256. That's why It might be better to remove this part.


| **`interoperableAddressName`** | |
|-------------------------|--------------------|
| *Description* | Display bytes as an [ERC-7930](./eip-7930.md) Interoperable Name. The wallet SHOULD parse the binary format, extract the target address and chain, and display it in the standard `<address> @ <chain> # <checksum>` format. |
| *Parameters* | --- |
| `types` | An array of expected types of the address (see [next section](#address-types-and-sources)). If set, the wallet SHOULD check that the address matches one of the types provided |
| `sources` | An array of acceptable sources for names (see [next section](#address-types-and-sources)). If set, the wallet SHOULD restrict name lookup to relevant sources |
| `senderAddress` | Either a string or an array of strings. If the address pointed to by `addressName` is equal to one of the addresses in `senderAddress`, the addressName is interpreted as the sender referenced by `@.from` |
| *Examples* | --- |
| `0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045@eip155:1#4CA88C9C` | Field Value = `0x00010000010114D8DA6BF26964AF9D7EED9E03E53415D37AA96045` |
