Frequently Asked Questions
Get clear, technical answers about our signature aggregation service, from security and integration to timelines and support.
A standard deployment, including smart contract development, integration with your existing frontend/backend, and initial testing, typically takes 3-5 weeks. Complex requirements, such as custom signer sets, novel cryptographic schemes, or support for more than 5 chains, can extend this to 6-8 weeks. We provide a detailed project plan with milestones after the initial scoping call.
