ENTERPRISE-GRADE ORACLE INFRASTRUCTURE
Core Capabilities of Our CosmWasm Oracle Contracts
Our custom CosmWasm oracle contracts are engineered for high-throughput DeFi and cross-chain applications, delivering secure, reliable, and cost-effective data feeds directly to your dApp's logic.
01
Multi-Source Data Aggregation
Integrate price feeds, randomness (VRF), and custom API data from multiple reputable providers (e.g., Chainlink, Band Protocol, Pyth Network) into a single, resilient on-chain result, mitigating single points of failure.
3-5 Sources

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFT ecosystems. Our code is built on Solidity 0.8+ with OpenZeppelin libraries, ensuring gas efficiency and security by design.
From concept to mainnet, we deliver contracts you can stake your business on.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting, minting controls, and governance hooks. - DeFi Primitives: Automated Market Makers (AMMs), staking pools, lending/borrowing logic, and yield optimizers.
- Security First: Every contract undergoes internal review and formal verification before submission to top-tier audit firms like
CertiKorTrail of Bits.
We specialize in complex, upgradeable systems using proxies (UUPS/Transparent) and modular architecture, allowing your protocol to evolve without migrating user funds. Typical delivery: 2-4 weeks for MVP, 6-8 weeks for full production system.

Frequently Asked Questions
Get clear answers on our process, timelines, security, and support for building custom, high-performance oracles on the Cosmos ecosystem.
For a standard oracle with 2-5 data sources, we deliver a production-ready, audited contract in 3-5 weeks. This includes design, development, testing, and a basic security audit. Complex oracles with custom aggregation logic or multi-chain support typically take 6-8 weeks. We provide a detailed project plan with milestones after the initial scoping call.
