You can now borrow Terra UST against bETH, a wrapped version of the stETH staking derivative for ETH 2.0.  

With the launch of bETH on Anchor, ETH stakers can now collateralise their stETH (in the form of bETH) on the Terra blockchain – in effect, allowing stakers from one blockchain to participate in another blockchain in an efficient manner.

I've gathered a list with all the tweets and videos that will teach you step by step how to get bETH, provide it as collateral on Anchor Protocol and borrow from UST on it!
