CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From initial logic design to deployment on
EVMchains (Ethereum, Polygon, Arbitrum) and final audit preparation. - Security & Gas Optimization: Every line of
Soliditycode is reviewed for vulnerabilities and optimized for minimum transaction costs. - Compliance Ready: Build with regulatory considerations in mind, incorporating patterns for pausable contracts, upgradeability, and access control.
Deliver a battle-tested, auditable smart contract system in as little as 4-6 weeks, reducing your technical risk and accelerating your go-to-market timeline.

END-TO-END DELIVERY
Our Development & Deployment Process
A structured, security-first methodology for building and launching your cross-chain ZK data oracle network. We manage the full lifecycle from architecture to production, ensuring reliability and speed to market.
01
Architecture & Design Review
We conduct a deep-dive technical assessment of your data feeds, consensus model, and target chains (EVM, Solana, Cosmos). This phase establishes the cryptographic and economic security model for your ZK proofs and validator incentives.
2-3 days
Initial Scoping
5+ chains
Architecture Support
02
ZK Circuit & Smart Contract Development
Our team builds the core ZK-SNARK/STARK circuits for data attestation and the on-chain verifier contracts. We use industry-standard frameworks (Circom, Halo2) and implement gas-optimized Solidity/Vyper for multi-chain deployment.

03
Rigorous Security Audits
Every component undergoes multiple security reviews. This includes internal peer review, automated analysis (Slither, MythX), and a formal audit by a top-tier third-party firm like Spearbit or Zellic before any mainnet deployment.

Testnet Deployment & Incentivization
We deploy your oracle network to public testnets (Sepolia, Holesky, etc.) and orchestrate an incentivized test phase. This stress-tests node performance, data accuracy, and slashing logic under real-world conditions.
