Frequently Asked Questions
Common questions from CTOs and technical leads about our StarkNet ZK-Rollup payment channel development service.
A standard, audited payment channel system with core features (deposit, off-chain state updates, dispute resolution, withdrawal) typically deploys in 3-5 weeks. Complex integrations (multi-asset support, custom fraud proofs, cross-chain messaging) can extend to 8-12 weeks. We provide a detailed sprint plan after the initial technical scoping session.
