CORE SERVICES
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From tokenomics to complex DeFi logic, we translate your business rules into immutable, auditable code.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, minting controls, and tax mechanics. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking contracts, and yield aggregators with sub-second finality.
- Security First: Every contract undergoes manual review and automated analysis using tools like Slither and MythX before deployment to mainnet.
- Full Lifecycle Support: We handle deployment, upgradeability patterns (Transparent/UUPS Proxy), and provide ongoing maintenance.

CRITICAL INFRASTRUCTURE
Why Deploy a Dedicated Randomness Feed
Public RPCs and shared oracles introduce unacceptable risk for applications requiring secure, verifiable, and performant randomness. A dedicated feed is non-negotiable for production-grade Web3 products.
01
Guaranteed Performance & Uptime
Eliminate the latency and downtime of public services. Our dedicated feeds provide sub-second response times and are backed by a 99.9% uptime SLA, ensuring your dApp's core mechanics are always operational.

02
Enhanced Security & Predictable Costs
Isolate your application from the attack surface and gas price volatility of shared networks. A dedicated feed provides a secure, private endpoint with fixed, predictable operational costs, eliminating surprise RPC bills.

Technical & Commercial FAQs
EVM Randomness Feeds: Common Questions
Answers to the most frequent questions CTOs and founders ask when evaluating a custom VRF deployment.
A standard, production-ready EVM-compatible VRF feed deployment typically takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with oracles like Chainlink or API3, on-chain testing, and a full security audit. Complex requirements (e.g., multi-chain deployment, novel cryptographic schemes) can extend the timeline, which we scope and agree upon upfront.
