Secure, audited smart contracts that power your Web3 product from MVP to mainnet.
We build production-grade smart contracts for DeFi, NFTs, and enterprise applications. Our process delivers audit-ready code in 2-4 weeks, built on Solidity 0.8+ with OpenZeppelin security patterns.
ERC-20, ERC-721, ERC-1155, and ERC-4626 vaults.Security is non-negotiable. Every contract undergoes internal review and is prepared for third-party audits by firms like
CertiKorTrail of Bits. We provide a comprehensive security report with each delivery.
Our development includes full documentation, deployment scripts, and post-launch support to ensure your protocol operates at 99.9% uptime.
Our verification oracle provides the foundational data integrity layer for DeFi protocols, NFT marketplaces, and enterprise applications, ensuring on-chain actions are triggered by validated, real-world events.
We aggregate and verify data from 50+ trusted sources (APIs, off-chain databases, IoT feeds) to create a single, reliable truth for your smart contracts. Reduces reliance on any single point of failure.
Every data point is signed with a verifiable cryptographic proof before being submitted on-chain. Provides tamper-evident audit trails and enables trust-minimized verification for downstream contracts.
A globally distributed, fault-tolerant network of nodes ensures 24/7 uptime and data delivery. Automatic failover and load balancing prevent service disruption during peak loads or attacks.
Define complex business rules (thresholds, time-locks, multi-sig confirmations) for when data is considered valid. Tailor the oracle's behavior to your application's specific risk profile without modifying core infrastructure.
Monitor the health and performance of your data feeds and verification jobs in real-time. Receive instant alerts for data anomalies, latency spikes, or failed submissions to your smart contracts.
Our core oracle contracts and node software undergo regular audits by firms like Trail of Bits and CertiK. Built with OpenZeppelin libraries and follow industry security best practices for managing private keys and data integrity.
Our On-Chain Verification Oracle delivers more than just reliable data feeds. It's a strategic asset engineered to drive measurable business results, from accelerating product launches to unlocking new revenue streams.
Launch new DeFi products, insurance protocols, and prediction markets in weeks, not months. Our pre-audited, production-ready oracles eliminate the need for in-house development and security validation.
Protect your protocol and users from oracle manipulation and data downtime. Our multi-source aggregation, cryptographic proofs, and decentralized node network provide enterprise-grade security guarantees.
Eliminate the cost and complexity of maintaining proprietary data pipelines, node infrastructure, and 24/7 monitoring. We handle the infrastructure so your team can focus on core product innovation.
Build transparent, verifiable applications where every data point is cryptographically proven on-chain. This demonstrable integrity builds user confidence and drives protocol adoption.
A technical breakdown of how Chainscore's on-chain verification model fundamentally differs from legacy oracle designs, highlighting key advantages in security, cost, and decentralization.
| Architectural Feature | Traditional Oracle (e.g., Chainlink) | Chainscore On-Chain Verification |
|---|---|---|
Data Integrity Proof | ||
Verification Logic Location | Off-chain (trusted nodes) | On-chain (verifiable smart contracts) |
Security Model | Trust in node operators | Trust in cryptographic proofs |
Data Tampering Risk | Medium (requires collusion) | Low (cryptographically enforced) |
Latency to Finality | High (multi-block confirmation) | Low (single-block, optimistic verification) |
Operational Cost | High (per-request fees + gas) | Predictable (gas-optimized verification) |
Developer Experience | Complex integration, multiple calls | Simple function call, unified response |
Transparency & Auditability | Limited (off-chain black box) | Full (all logic on-chain) |
Time to Integrate | 2-4 weeks | < 1 week |
Typical Annual Cost for High Volume | $50K - $200K+ | $15K - $75K |
A structured, four-phase approach to deliver a secure, high-performance on-chain verification oracle. We provide clear milestones, transparent communication, and guaranteed outcomes at every step.
We define your verification logic, data sources, and integration points. Deliverables include a technical specification document, system architecture diagram, and a detailed project roadmap with sprint planning.
Our team builds the off-chain verifier and on-chain smart contracts. We implement security patterns from OpenZeppelin, conduct internal audits, and optimize for gas efficiency and finality speed.
Your oracle undergoes rigorous testing, including unit/integration tests, adversarial scenario simulations, and a formal audit by a third-party security firm (e.g., Spearbit, Code4rena).
We manage the mainnet deployment, configure decentralized node infrastructure, and establish 24/7 monitoring with alerting. You receive a full operations runbook and performance dashboard.
Secure, production-ready smart contracts built for your specific business logic.
We architect and deploy custom smart contracts that form the foundation of your Web3 application. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.
Deploy with confidence. Our contracts are built to handle real-world volume and adversarial conditions.

An on-chain verification oracle is a secure, decentralized service that fetches, verifies, and delivers real-world data or computational proofs to smart contracts. You need one to build reliable DeFi protocols, prediction markets, insurance dApps, or any application requiring tamper-proof external data. Our oracles ensure data integrity with cryptographic proofs, preventing manipulation and single points of failure that plague simpler data feeds.
