Why it exists
Sentinels only work if every participant can trust the results. USB.Trade combines Risc0’s Boundless Network for zero-knowledge proofs with MaldaLab’s sequencer technology to validate that sentinel modules followed policy, touched approved venues, and settled in the right order.
You stay in custody while gaining cryptographic assurance that orchestration decisions were executed faithfully—even when they span multiple chains.
How the layer is assembled
Sentinel actions are logged with signatures, calldata, and oracle inputs so they can be fed into Risc0 circuits.
Risc0 generates proofs that the executed plan respected policies (capital limits, allowlists, timing windows).
MaldaLab’s ASMS ensures multi-chain steps commit in the right order and fall back gracefully if venues degrade.
Proofs and state diffs are published on-chain plus via APIs so wallets, auditors, and partners can verify outcomes.
Security and roadmap
- Independent auditors validate circuits, sequencer logic, and slashable commitments before mainnet.
- Fallback mode allows users to force manual settlement if proofs or sequencing windows stall.
- Future iterations add attestation markets so third parties can run provers and earn fees for supplying capacity.
We will publish deeper deep dives—including benchmark data and contract references—as components graduate from internal testnets.
