FREQUENTLY ASKED QUESTIONS

Answers & Technical Insights

Clear, transparent insights about our development process, tech stack, and collaboration.

Why should businesses in Rotterdam choose Cromp IT Solution for Crypto Development?↓
We bring senior full-stack capability, rapid bi-weekly release cycles, and obsessive UI/UX polish directly to Rotterdam founders and teams without the overhead or latency of traditional monolithic agencies.
How does our Rotterdam team coordinate with Cromp IT Solution during the build?↓
We collaborate seamlessly via CET / CEST (exact European day-to-day synchronous alignment). Your team has direct, real-time access to founder Ayush and principal engineers via dedicated communication channels and transparent staging preview deployments.
How do you ensure smart contracts are secure against hacks?↓
We follow strict security standards (checks-effects-interactions pattern, reentrancy guards, OpenZeppelin verified bases), run comprehensive 100% branch test coverage in Foundry, and prepare protocols for independent third-party audit verification.
Can you build non-crypto friendly web experiences that use blockchain under the hood?↓
Yes. Using account abstraction (ERC-4337), social login bridges, and gas-sponsorship mechanisms, we create seamless consumer applications where users never have to manage private seed phrases or pay manual gas fees.
Which blockchains do you build on?↓
We specialize in Ethereum and major EVM-compatible ecosystems including Polygon, Arbitrum, Optimism, Base, and Avalanche, as well as high-throughput layer-1 networks.
