Frequently Asked Questions

Get specific answers on timelines, security, and integration for your payment solution.

A standard multi-asset payment aggregator deployment takes 3-5 weeks from kickoff to production. This includes smart contract development, frontend integration, testing, and security audit integration. Complex requirements like custom token whitelisting or multi-chain settlement may extend this by 1-2 weeks. We provide a detailed sprint plan within the first week of engagement.
