CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.
- Custom Logic: Build bespoke
ERC-20,ERC-721, or complex DeFi/CeFi protocols with gas-optimized Solidity 0.8+. - Full Lifecycle: From initial spec and
Hardhat/Foundrytesting to deployment and upgrade management via transparent proxy patterns. - Security First: Every contract undergoes peer review and testing against known attack vectors before final audit.
Deliver a secure, functional smart contract system in as little as 2-4 weeks, with a guaranteed 99.9% uptime SLA post-deployment.

Stealth Airdrop SDK Development FAQs
Get specific answers on timelines, costs, security, and support for our custom stealth airdrop SDK development service.
We deliver a production-ready, audited stealth airdrop SDK in 4-6 weeks for a standard implementation. This includes design, core development, integration of privacy layers (e.g., Semaphore, zk-SNARKs), comprehensive testing, and a final security audit. Complex requirements like custom tokenomics or multi-chain support may extend the timeline, which we define in a detailed project plan before engagement.
