Engineering for the next decade of the internet

XDefiDev is a full-stack software engineering studio. We build custom software, AI and LLM applications, n8n workflow automation, cloud and DevOps infrastructure, APIs, and web and mobile apps — plus smart contracts, DeFi protocols, dApps, and blockchain platforms for founders, startups, DAOs and enterprises.

Yes. Our products section holds complete platforms delivered as source code with a commercial licence, priced at a fixed figure and payable with cryptocurrency. You get the code and run it on your own infrastructure.

We build on Ethereum, BNB Smart Chain, Avalanche, Polygon, Fantom, Base and Solana, as well as custom EVM-compatible networks. That includes Layer 2 solutions and bespoke Layer 1 chains with Proof-of-Stake, Proof-of-Authority or Delegated Proof-of-Stake consensus.

Every contract follows a security-first process: threat modelling, code review, unit and integration tests, gas optimisation, and a third-party audit from firms such as CertiK or Hacken. We also apply reentrancy guards, access control and upgradeability patterns to reduce exploit risk.

A simple token or contract can ship in under a week. A full dApp with wallet integration typically takes three to eight weeks, while a custom network or institutional exchange runs for several months. We work in weekly deliverables so you always know where things stand.

You can pay in BTC, ETH, LTC, SOL, USDT, USDC and other major coins through a hosted checkout. We generate a unique deposit address and QR code per order and confirm automatically once the network settles. No account required.
