BTC LSTs are exploding.
But most are:
– custodial (WBTC, Swell)
– yield-farmed (pumpBTC, SOLV)
– not truly crosschain BTC, Lombard)

Then there’s AuroBTC - @union_build ZK-native Bitcoin LST.
Here's why it’s different 🧵

🔐ZK custody > multisigs
🌉True crosschain (ETH, Cosmos) > EVM-only
💸Protocol yield > airdrop hype
🏗️Composable from day one: lending, vaults, collateral
🧠Led by Gandalf (ex-Bedrock, $700M+ TVL)

Union already moved $40M+ BTC into Babylon.
No relayers. No oracles.
Light clients, and proof-of-integrity.

AuroBTC isn’t just another wrapped Bitcoin.

It’s what BTCfi needed all along:
– Secure
– Yield-bearing
– Crosschain by design
ZK is the engine. Union is the layer.
AuroBTC is the unlock.
