Overall Architecture of SolvBTC
*** #### BTC Mainnet Architecture The BTC Mainnet Architecture defines SolvBTC’s **Bitcoin-native custody and issuance foundation**. It is built around a **FROST-based threshold signing network** and a structured Vault system, ensuring that: * Native BTC custody remains fully on Bitcoin Mainnet * Private keys are never reconstructed on any single participant * SolvBTC minting and redemption are executed through governed, auditable signing flows * Long-term asset security and reserve integrity are enforced at the Bitcoin layer This architecture serves as SolvBTC’s **security anchor and final settlement layer**, prioritizing correctness, minimized trust assumptions, and long-term capital safety. *** #### On-chain Liquidity Architecture The On-chain Liquidity Architecture defines SolvBTC’s **smart-contract execution and liquidity layer**. It is designed to support protocol-level liquidity usage **under explicit authorization and reserve constraints**, while remaining consistent with SolvBTC’s Bitcoin-native custody guarantees. Key components of this architecture include: * Deposit Contracts for on-chain SolvBTC minting * Whitelisted Swap Contracts for authorized, atomic SolvBTC-to-reserve-asset conversion * Standard Redemption Contracts for general user redemption paths * A Safe Vault structure coordinating asset custody and delivery This architecture enables SolvBTC to participate in on-chain liquidity, liquidation, and DeFi execution scenarios without exposing unrestricted redemption paths or weakening reserve discipline. *** #### Architectural Alignment The BTC Mainnet Architecture and the On-chain Liquidity Architecture are **designed independently**, yet are architecturally aligned through: * A **unified SolvBTC asset model** * A shared **Auditors-based governance framework** consistent with SolvBTC’s mainnet security assumptions This alignment establishes a common security and asset consistency baseline across execution domains. Under this alignment, future designs may introduce limited, governed mechanisms to adjust liquidity distribution across execution domains, potentially including rebalance-oriented designs, without altering the core security model of either system. --- # Agent Instructions This documentation is published with GitBook.
