Union's Auro BTC: ZK-verified native Bitcoin LST
Quote115 words
Auro BTC is Union's native Bitcoin LST that uses ZK-verified custody and mint/burn logic to avoid trusted bridges, oracles and relayers. It targets custodial risk, weak cross-chain use and lack of native yield, and earns Union commissions on staking rewards.

Interesting stuff happening on @union_build ngl
TL;DR:
- Auro BTC is the native Bitcoin Liquid Staking Token (LST) launched by the Union Network. Its name is derived from the Latin word for "golden".
- It aims to solve common problems found in existing Bitcoin LSTs, such as high custodial risk, poor cross-chain capabilities, and a lack of sustainable, native yield.
- Auro BTC leverages Union's ZK-powered interop layer, which enables ZK-verified custody and mint/burn logic, allowing the Auro BTC to be natively and securely used across various ecosystems without needing trusted bridges, oracles, or centralized relayers.
- The asset will generate revenue for Union from staking reward commissions as @e_beriker outlined recently.
Quite bullish imo.
