Substrate Pallet for Streaming Oracles

We build custom Substrate pallets that provide native, high-performance oracle functionality for live data feeds within Polkadot and Kusama parachains.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy custom smart contracts that are secure by design and gas-optimized. Our process includes formal verification, comprehensive unit testing, and peer review to ensure your core logic is robust and reliable before mainnet launch.

  • Full-Stack Development: From ERC-20/721/1155 tokens to complex DeFi primitives, cross-chain bridges, and DAO governance systems.
  • Security-First Process: Adherence to OpenZeppelin standards, integration of upgrade patterns like TransparentProxy, and preparation for third-party audits.
  • Measurable Outcomes: Deliver a production-ready MVP in 2-4 weeks with documented code, deployment scripts, and a clear path to scaling.

ARCHITECTURAL ADVANTAGES

Why Build a Native Streaming Oracle Pallet?

Integrating a custom oracle pallet directly into your Substrate-based blockchain delivers fundamental advantages over external oracle services, providing superior performance, security, and control for your decentralized applications.

01

Sub-Second Finality & Zero Latency

Eliminate network hops and API delays. Data is written directly to your chain's state, enabling real-time price feeds and event triggers with deterministic finality for high-frequency DeFi and trading applications.

Cross-Chain Latency
02

Native Security & Consensus Integration

Your oracle logic is secured by your blockchain's validator set, inheriting its battle-tested cryptographic security. No reliance on external, potentially vulnerable multisig bridges or third-party attestations.

On-Chain Security

03

Custom Data Feeds & Logic

Define precisely what data you need and how it's aggregated. Support niche assets, proprietary indices, or complex off-chain computations (like TWAPs) that generic oracles cannot provide.

Predictable, On-Chain Cost Structure

Eliminate unpredictable gas fees from external networks. Oracle updates consume your chain's native token, simplifying economic modeling and user experience for your dApp's transactions.

Sovereign Governance & Upgrades

You control the upgrade path, data sources, and emergency pauses via your chain's governance. No waiting for third-party provider decisions that may not align with your protocol's needs.

Reduced Systemic Risk

Decouple your application's availability from public oracle networks. Avoid cascading failures during high congestion on Ethereum or other L1s, ensuring your core functionality remains operational.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, four-phase approach to deliver a production-ready Substrate pallet for streaming oracles, minimizing your technical risk and accelerating time-to-market.

01

Phase 1: Architecture & Design

We conduct a deep technical assessment of your data requirements and chain architecture. This phase delivers a detailed technical specification, including pallet API design, data source integration strategy, and a comprehensive security model.

Frequently Asked Questions

Get clear answers on development timelines, security, and support for your custom oracle solution.

A standard, production-ready Substrate pallet for streaming oracles with core features (data ingestion, aggregation, on-chain verification) typically takes 3-5 weeks from specification to audit-ready code. Complex integrations (e.g., cross-chain verification, advanced staking logic) can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
