| | *Description* | Display byte array as an [ERC-7930](./eip-7930.md) Interoperable Name. The wallet MUST validate the checksum and format the display as `<address>@<chain>#<checksum>`. | |

I wonder if this type could also be used for specifying contracts on chains in one field, as in contract deployments:
{
"chainId": 1,
"address": "0xdAC17F958D2ee523a2206206994597C13D831ec7"
}

| | *Parameters* | --- | | ||
| | `resolveAddress` | Boolean. If set to `true`, the wallet SHOULD attempt to resolve the inner address segment using the same logic as `addressName` (e.g., resolving ENS names). Defaults to `false`. | |

I think strictly speaking this is "reverse resolution" https://docs.ens.domains/web/reverse

Abstract
This pull request extends ERC-7730 by introducing support for EIP-7930 Interoperable Addresses. The goal is to enable wallets to safely parse and display chain-specific addresses, improving security for cross-chain interactions.
Specification
A new format specifier,
interoperableAddress, has been added to the "Bytes formats" section. This instructs wallets to interpret a bytes value as an EIP-7930 binary payload and display it in its human-readable "Interoperable Name" format.
