Frequently Asked Questions

Custom software development, integrations, mobile apps, timelines, and post-launch support.

DeFi Development covers design, smart contract development, and deployment of DeFi development — including Web3 frontends, wallet integrations, crypto APIs, and admin platform backends for operations and compliance.

We primarily build on EVM-compatible chains such as Ethereum, BSC, and Polygon. Architecture can extend to L2s and other networks based on your tokenomics and liquidity requirements.

We follow audit-ready development practices and can coordinate third-party audits or provide pre-audit consulting, remediation, and test coverage for your contracts.

Wallet or token MVPs often launch in 8–12 weeks. Exchanges, NFT marketplaces, and DeFi protocols use phased delivery with testnet beta before mainnet launch.

Project cost depends on scope, integrations, and compliance needs. MVPs often start from $15,000–$40,000; Inversionsys with mobile apps, payments, and industry APIs typically range higher. We provide a phased quote after a discovery call so you know budget before build begins.
