Not your usual BTC LST.
Introducing Auro BTC, the Union network’s native Bitcoin LST, which brings custody, composability, and crosschain liquidity into one trust-minimized design.
This is how Bitcoin scales across DeFi 🧵↓

1/ Bitcoin LSTs are emerging as one of the fastest-growing categories in DeFi, with combined TVL approaching $10+ billion.
By transforming idle Bitcoin into yield-generating assets, Bitcoin LSTs have unlocked new utility for the world’s most valuable digital asset.
2/ Yet, existing BTC LSTs are constrained by their designs as isolated smart contracts, which limits native cross-chain scaling, secure custody coordination, and seamless DeFi composability.
3/ Bitcoin LSTs depend on interoperability protocols like Union to realize their full potential across chains.
Or, Union could be the distributor itself.
And so it shall.
4/ Union is developing a BTC LST that will leverage Union interop to create a crosschain asset that is composable, verifiable, and usable anywhere.
Auro BTC will be instantly available on Ethereum, Cosmos, and other ecosystems with ZK-verified custody and mint/burn logic.
