Need a help with developing cross chain platfrom

Hi everyone,

I’m working on building a cross-chain protocol with the Sui network. Initially, I used Wormhole, but I encountered a limitation—it only supports wallets created with mnemonic keys and does not work with wallets created using zkLogin.

However, I noticed that other cross-chain platforms like Sui Bridge support all types of wallets, whether created with mnemonic keys or zkLogin. I would love to understand how they achieve this.

Could anyone provide insights on the best approach to developing a cross-chain platform that supports all wallet types? Are there specific frameworks, libraries, or design patterns that I should consider?

Looking forward to your suggestions!

Thanks in advance!
