# High-Level Architecture

SolvBTC is built on two complementary architectural layers:

#### BTC Mainnet Architecture

* Threshold-based signing using a FROST-based design
* Structured vault and custody framework
* Governed and auditable Bitcoin movement rules

#### On-Chain Liquidity Architecture

* Reserve-aware minting and redemption contracts
* Protocol-level execution paths
* Unified asset custody and delivery logic

Together, these layers ensure that SolvBTC remains:

* **Secure at the Bitcoin layer**
* **Efficient and composable at the on-chain execution layer**
