Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for building your high-performance payment channel network.
A standard, production-ready EVM payment channel network with core features (deposit/withdrawal, channel management, dispute resolution) typically deploys in 4-6 weeks. Complex integrations (e.g., cross-chain asset support, custom fraud proofs, oracles) can extend this to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial architecture review.
