Core Features
Bitcoin as Layer Zero
Bitcoin has long served as the foundational store of value in the crypto ecosystem — battle-tested, censorship-resistant, and fully decentralized. However, its role has remained largely passive. BTO reimagines Bitcoin not just as an asset, but as an operational base layer — a "Layer Zero" — upon which new liquidity, programmability, and interoperability can be constructed.
This paradigm shift doesn't require Bitcoin to leave its chain or compromise on decentralization. Instead, BTO leverages the security and finality of the Bitcoin network while allowing its liquidity to operate natively in DeFi environments. The original Bitcoin remains untouched and secure, while its financial potential becomes active and accessible through BTCx.
In essence, Bitcoin is no longer confined. Through BTO, it becomes the gravity core for a programmable, composable DeFi economy — while retaining its trust-minimized ethos.
4.2 Omnichain Compatibility
BTCx is not limited to a single blockchain or ecosystem. As a native omnichain asset built using the LayerZero OFT (Omnichain Fungible Token) standard, BTCx is inherently capable of flowing across multiple EVM-compatible networks, such as:
Ethereum
Arbitrum
Optimism
Base
zkSync
Polygon (future support)
Scroll (future support)
This broad compatibility unlocks seamless cross-chain functionality without relying on traditional bridges or centralized custody. Users can deploy liquidity across chains based on capital efficiency, yield optimization, or protocol incentives — all without the friction or risk that comes with wrapping and re-wrapping assets.
Each instance of BTCx across supported chains maintains verifiable alignment with its underlying Bitcoin reserve, and users can transfer assets with native gas — no need for bridging interfaces or relay middleware. This is cross-chain finance, without the bridges.
Reserve Transparency
Every BTCx token in circulation is 1:1 backed by real Bitcoin held in decentralized smart contract vaults. These vaults are publicly auditable, secured via multisignature mechanisms, and operate entirely on-chain. No single entity has access or control over the reserves.
Each vault interaction — deposits, minting, redemption, burns — is transparently recorded and verifiable through BTO’s explorer interface. Users, developers, and third-party auditors can confirm reserve integrity in real-time.
To ensure further accountability, the vaults operate under time-locked governance, allowing the community to track any proposed logic upgrades or operational changes before they take effect.
This is not synthetic liquidity. It is real, verifiable BTC — programmable through Ethereum, accessible across chains, and provably owned by its user.
Protocol-Level Security
Security is not an afterthought. It is the bedrock of BTO's architecture. The protocol employs a layered security model composed of:
Multisig Vault Governance: All Bitcoin vaults are controlled by smart contracts governed by multisig wallets, eliminating single points of failure.
Time-Locked Smart Contracts: All critical upgrades are subject to delayed execution mechanisms, allowing community oversight and rollback contingencies.
Zero-Knowledge Access Paths: To maintain privacy and integrity, access rights to vault interactions are gated via ZK proofs, ensuring no metadata leakage while maintaining deterministic verifiability.
Immutable Contract Modules: Core functions are deployed with upgrade restrictions, minimizing the attack surface and ensuring long-term operational consistency.
Together, these features create a robust, resilient protocol with trust-minimized guarantees — matching Bitcoin’s ethos, not just its brand.
