FROM REQUIREMENTS TO PRODUCTION
Our Proven Development Methodology
We deliver production-ready Cosmos CosmWasm oracles using a structured, security-first process that reduces time-to-market and technical risk for your Web3 application.
01
Requirements & Architecture Design
We begin with a deep technical workshop to define your oracle's data sources, update frequency, and consensus model. We architect the smart contract and off-chain relayer system for optimal gas efficiency and reliability on the Cosmos ecosystem.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process is built on security-first principles using Solidity 0.8+, Vyper, and audited libraries like OpenZeppelin.
Deliver a battle-tested, gas-optimized contract suite in as little as 2-4 weeks for your MVP.
- Full Lifecycle Support: From initial design and
Hardhat/Foundrytesting to mainnet deployment and upgrade management viaTransparentorUUPSproxies. - Security Rigor: Mandatory internal audits, formal verification with tools like
Certora, and preparation for third-party audits from firms likeTrail of BitsorQuantstamp. - Protocol Integration: Seamless compatibility with major standards (
ERC-20,ERC-721,ERC-1155) and DeFi primitives (Uniswap V3, Aave, Chainlink oracles).

Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for building custom oracles on Cosmos.
A standard, production-ready oracle with 2-3 data sources and custom aggregation logic typically takes 3-5 weeks from kickoff to mainnet deployment. This includes smart contract development, integration testing, security review, and deployment support. More complex oracles with proprietary logic or multiple chains may extend to 6-8 weeks.
