Security and audit readiness controls
Smart contract development services need more than code. Our delivery process creates the artifacts your internal risk team and external auditor need before funds, assets, or users interact with contracts.
- Threat modeling for reentrancy, access control, oracle manipulation, signature replay, pricing assumptions, and upgrade risk.
- Unit, integration, and invariant tests for core flows, role boundaries, error cases, and edge conditions.
- Static analysis and manual review before external audit handoff, followed by remediation support.
- Deployment scripts, multisig setup, admin role documentation, and monitoring checkpoints.
- Maintenance planning for dependency upgrades, chain changes, incident response, and future protocol extensions.

Success Stories of Blockchain Development
DCLEX
DCLEX approached 10Clouds to help them build a groundbreaking stock exchange that would use blockchain to provide secure and transparent trading. The work would include product inception, branding and visual communication. It would also cover UI design, service design, development, and providing blockchain support.
Qenta
Firm ground and trust are the basics in the world where value is attributed to a line of code. Especially, when that code is supposed to represent gold. Qenta (former Emergent), a fintech company, wanted to create a gold-backed stable coin (G-Coin) and a verified supply chain for trusted gold. Ultimately, 10Clouds helped Qenta create an alternative to cash with responsibly sourced, digital gold.
Crescent
The platform offers users 100x higher interest rates compared to traditional savings accounts with up to 6% APY, no minimums and no hidden fees.
