How to programmatically use Terra bridge?

Forgiveness in advance if this sounds noob’ish but im relatively new to Terra

Im working on a “strategy fund” like protocol where people can deposit their HODL coins (eth, btc, luna) and protect their downside with put option… and be able to generate yield using anchor protocol. Problem is, im not sure how I can use smart contract to transfer the funds over to terra ecosystem.

If there’s a tutorial on how to do this, URL would be helpful.
