Frequently Asked Questions
Get clear answers on our process, security, and deliverables for integrating your DeFi protocol across multiple blockchains.
Our standard delivery timeline is 4-8 weeks, depending on the number of target chains and protocol complexity. A typical 3-chain integration (e.g., Ethereum, Arbitrum, Polygon) with a custom bridge solution takes 6 weeks from kickoff to mainnet deployment. This includes design, development, internal audits, and a testnet launch phase.
