Security Stack
Secure by Default.
Blackhole introduces a new execution stack purpose-built for modular, secure-by-default DeFi infrastructure. Existing execution systems were designed for speed, not safety — leaving developers to patch together fragile routing, unsafe signing flows, and reactive error handling.
Blackhole replaces that with a deterministic and programmable execution pipeline — starting before the signature and enforced through final onchain execution.
At the entry point is Umbra — an offchain firewall that filters transaction routes using static threat detection and lightweight machine learning, identifying malicious patterns and risky behaviors in real time — before the user signs. It eliminates the need for slow, RPC-heavy simulations, and scales to high-volume environments like aggregators and agents.
Onchain, execution is enforced by GravCore — our runtime-aware smart contract that validates preconditions, activates fallback routes, and ensures that signed transactions execute exactly as intended — or not at all. GravCore supports multiple fallback paths embedded in a single signature, allowing transactions to recover safely from slippage, bridge failures, or contract-level reverts — without asset loss or user intervention.
Together, Umbra and GravCore form a complete execution safety layer:
— Pre-signature validation (offchain)
— Runtime enforcement and recovery (onchain)
— Modular, deterministic, and fault-tolerant by design
This is not just a safer SDK — it’s a shift in how execution should work across chains. Blackhole makes it possible.
