# 🔗 Passport Interoperability Multi-chain Aggregation In the Web3.0 world, different pieces of a user's information dataset are scattered in separate addresses on different public chains. In other words, a user may have multiple on-chain addresses on different blockchains, such as Ethereum, Polkadot, Cosmos, Binance Smart Chain, and so on. The data contained within one single address cannot fully demonstrate the user's comprehensive identity information. Therefore, Unomi will help users create a Multi-chain based passport, which will integrate address information scattered on various chains and users’ social account information. That passport will be comprehensive and all-around. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
