Off-chain smart contracts enforced by TEEs: private by design, cross-chain by default, and compatible with any network (including Bitcoin!).
Arbitrary code secured in a hardware enclave to implement your account (key) logic.
DogeOS uses CubeSigner to verify that only properly attested validator nodes can sign transactions allowing users to withdraw funds from DogeOS. These custom policies give DogeOS strong guarantees that only software they wrote has signing privileges—that is, every withdrawal signature used in the DogeOS multi-sig originates from a DogeOS-owned Nitro Enclave running the expected CubeSigner software. The result is a signing workflow that’s resistant to node compromise and other common bridge attacks.
“CubeSigner gives DogeOS a secure bridge layer by ensuring only our own verified enclave code can sign withdrawals. It’s a critical safeguard against node compromise and the kind of exploits that plague other ecosystems."
Enforce off-chain smart contract logic on Bitcoin and beyond.
Write arbitrary smart contract logic in any programming language that compiles to WebAssembly (Wasm).
Implement a single smart contract to interface with—and act as your account on—any chain.
Get cryptographic proof that the correct smart contract code is running unaltered inside the TEE. Use multi-party approvals and timelocks to restrict contract upgrades.
Keep your smart contract logic and data private: you don’t have to expose computations (or data) on-chain (unless you want to).
Take hardware-enforced logic where smart contracts can’t go.
