Frequently Asked Questions
Common questions from CTOs and technical founders about deploying a secure, scalable cross-chain payment gateway.
Standard gateway deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with 2-3 target chains (e.g., Ethereum, Polygon, Arbitrum), and comprehensive security testing. Complex multi-chain deployments with custom tokenomics or advanced features may extend to 6-8 weeks.
