DELIVERABLES
Business Outcomes for Your Platform
Our StarkNet Cairo ZK-Rollup development delivers concrete, measurable results for bond issuance and trading platforms. We focus on the technical outcomes that directly impact your bottom line and operational efficiency.
01
Reduced Transaction Costs
Move bond issuance and settlement off-chain with StarkNet's ZK-Rollup, slashing gas fees by 90-99% compared to Ethereum L1. This makes micro-transactions and high-frequency trading economically viable.

Frequently Asked Questions
Common questions from CTOs and technical founders about building ZK-rollup bond protocols on StarkNet.
From specification to mainnet launch, a standard bond issuance and management protocol takes 6-10 weeks. This includes 2 weeks for architecture and smart contract design, 3-4 weeks for Cairo development and internal testing, 1-2 weeks for a third-party security audit, and 1-2 weeks for deployment and integration. Complex features like multi-currency settlement or cross-chain interoperability can extend the timeline.
