CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
- Full Lifecycle Development: From initial architecture and
Solidity/Rustcoding to deployment, verification, and on-chain monitoring. - Security-First Approach: All code follows OpenZeppelin standards and undergoes rigorous internal review before third-party audits from firms like CertiK or Quantstamp.
- Gas Optimization: We write efficient code to minimize transaction fees, a critical factor for user adoption and protocol sustainability.
Deliver a secure, audited, and fully functional smart contract system in as little as 4-6 weeks, drastically reducing your technical risk and time-to-market.

ENTERPRISE-GRADE SECURITY
Core Features of Our MEV-Resistant Oracle Pallet
Our Substrate-native oracle pallet is engineered to deliver tamper-proof, high-frequency data to your parachain with built-in protections against front-running and data manipulation, ensuring your DeFi applications operate with integrity.
01
Multi-Source Data Aggregation
We aggregate price feeds from 15+ decentralized and institutional sources, applying a weighted median algorithm to filter out outliers and deliver a single, manipulation-resistant value. This reduces reliance on any single point of failure.

02
Commit-Reveal Scheme
Our core MEV-resistance mechanism. Data providers submit encrypted commitments on-chain before revealing values, making front-running and data-snooping attacks economically unfeasible for your application's users.

03
Slashing & Bonding Mechanism
Providers must stake DOT/KSM tokens as a security bond. Provably incorrect or delayed data submissions trigger automatic slashing, financially aligning provider incentives with network honesty and reliability.

Gas-Optimized On-Chain Verification
Built with Substrate's weight system in mind. Our pallet performs complex verification (like signature aggregation) off-chain, submitting only minimal proofs to keep your parachain's block space usage and gas costs low.

Customizable Data Feeds & Thresholds
Not just for prices. Configure the pallet for any off-chain data (sports scores, weather, IoT). Set custom deviation thresholds, heartbeat intervals, and minimum provider counts per feed via governance or sudo.

Frequently Asked Questions
Get clear answers on our technical approach, timeline, and support for building a custom oracle pallet for your Polkadot parachain.
A standard Substrate oracle pallet with core data feeds and security features takes 4-6 weeks from kickoff to mainnet deployment. This includes 2 weeks for design & development, 1 week for internal testing and audit, and 1-2 weeks for integration and deployment on your testnet/mainnet. Complex requirements like custom aggregation logic or multi-chain data sourcing can extend this timeline, which we scope and quote for upfront.
