I have seen that team is considering to cross chain and there are already well known network like matic, ftm, Avalanche.
But my suggestion is to consider well under rated protocol called fusion.
Fusion holds so many key benefits considering their competitors.
Fusion's unique Time-Lock feature enables you to extract time-value out of your digital assets
Cross-chain interoperability through a decentralized custodian model (DCRM)
Manage and control private keys in a distributed manner with DCRM technology
The most fascinating technology of fusion protocol is time lock mechanism to extract value from time on digital assets and also security while trusting 3rd party applications.
Example of timelock: let's IRON is in fusion protocol, then I can send that iron from my wallet to other user with a time range and lets assume it like "07-MAY-2021" to "30-MAY-2021". On may 30 the token will return automatically to my wallet.
The person who held this iron token for one month is the owner of the token for 1 month and he can stake it for a month to get returns.
The highlight is the part from "30-May-2021" to infinity is still belong to the actual owner me. So I no need to wait for my fund to return. Instead I can send the token time locked from "30-MAY-2021" to "30-JUN-2021" to another person without worrying about anything.
Moreover, they fusion protocol gonna launch a Decentralised celcius sought of app called Chainge with million people in waiting list. So doing crosschain with fusion protocol can give us free listing on the new app.
Apart from all, it makes IRON be the first stable token to have time lock mechanism.
Please vote for fusion if interested or choose others if not interested
