PROVEN METHODOLOGY
Our Development Process
A structured, security-first approach to delivering production-ready light client verification protocols that integrate seamlessly with your existing infrastructure.
01
Architecture & Protocol Design
We design the verification logic and data structures (Merkle proofs, sync committees) for your target chain (Ethereum, Cosmos, Polkadot). This includes defining the trust assumptions, finality guarantees, and light client state transition rules.
2-4 weeks
Design Phase
5+ chains
Protocol Experience
02
Implementation & Core Development
Our engineers write the core verification logic in Rust, Go, or Solidity. We implement cryptographic primitives (BLS signatures, Keccak/SHA256), header validation, and proof verification following the official chain specifications.

Security Patterns
04
Integration & SDK Delivery
We package the verified protocol into a developer-friendly SDK (JavaScript/TypeScript, Python) with clear APIs, documentation, and example integrations for wallets, bridges, and oracles to consume light client data.

Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building secure, production-ready light client verification protocols.
A standard, production-ready light client verification protocol for a single chain (e.g., Ethereum, Polygon) typically takes 4-6 weeks from specification to audit-ready delivery. Complex multi-chain or consensus-specific (e.g., Tendermint, Polkadot) integrations can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones during scoping.
