Phase 1 — Discovery & Architecture
Step 01

Threat map in day 1.

We audit your current OTA pipeline — CI/CD, signing keys, CDN hops, current verification — and produce a written threat model before a line of code is written.

Step 02

Registry live by week 2.

OTARegistry deployed to testnet. Rust verifier running locally. A test malicious bundle is rejected before the sprint is over — you see it working, not just a design doc.

Step 03

Multi-sig wired by week 4.

Gnosis Safe quorum configured. First offline signing ceremony completed. The registry requires M-of-N hardware wallets for every future publish. One compromised machine is no longer enough.

Step 04

Mainnet + SLA by week 8.

Registry deployed to mainnet. Managed signing SLA active. Your next OTA update is the first one verified on-chain. Every future update is public, auditable, and cannot be pushed without the hardware wallet quorum.

Phase 2 — Build

Four sprints. Every artifact testable before mainnet.

Sprint 1: verifier rejects a malicious bundle on your machine. Sprint 2: multi-sig quorum stops a single compromised key from publishing. Sprint 3: staged rollouts and instant revoke work on testnet. Sprint 4: mainnet deployment with signing SLA live. You sign off each sprint before we proceed.

On-Chain Registry Live Before Launch

The OTARegistry contract is deployed and verified on mainnet. The Rust verifier is integrated and tested on device before any production update ships.

Post-Deploy Signing SLA

Post-launch we stay on. Managed multi-sig quorum, sub-5-minute hash publication, and instant revoke support — SLA-backed.
