PREDICTABLE, SECURE, AND SCALABLE
Our Delivery Process: From Assessment to Live Recovery
A structured, four-phase engagement model designed for technical leaders who need reliable state recovery without disrupting their roadmap. We deliver a production-ready solution with clear milestones and guaranteed SLAs.
01
Phase 1: Architecture & Threat Assessment
We conduct a deep-dive audit of your EVM smart contract architecture to identify critical state dependencies and single points of failure. This phase establishes the recovery point objective (RPO) and recovery time objective (RTO) for your specific application.
Deliverables: Technical assessment report, risk matrix, and a tailored backup strategy document.

Frequently Asked Questions
Get clear answers about our process, security, and outcomes for protecting your protocol's critical state.
We implement a multi-layered, automated system. First, we instrument your contracts to emit state change events. Our off-chain infrastructure listens to these events and your contract logs, serializing the data into a structured format. This data is then immutably stored on decentralized storage (like Arweave or IPFS) and backed up to secure, encrypted cloud storage. Recovery involves deploying a new contract instance with a constructor that accepts the serialized state, allowing you to restore operations from any block height. We provide a full disaster recovery runbook for your team.
