CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From token standards to complex DeFi logic, we deliver contracts that are gas-optimized, upgradeable, and secure by design.
- Standard & Custom Tokens:
ERC-20,ERC-721,ERC-1155, and custom implementations with minting, vesting, and governance modules. - DeFi & dApp Logic: Automated market makers (AMMs), lending pools, staking systems, and multi-signature wallets.
- Security-First Process: Development follows OpenZeppelin best practices, includes third-party audit preparation, and features a 99.9% deployment success rate.
- Full Lifecycle Support: From initial design and development to mainnet deployment, monitoring, and post-launch maintenance.

ARCHITECTURE ADVANTAGES
Why Build a ZK-Native Oracle with Chainscore
Move beyond generic oracle feeds. Our ZK-rollup optimized data delivery is engineered for the unique performance and security requirements of modern L2s, delivering verifiable, low-latency data with cryptographic guarantees.
01
Zero-Knowledge Proof Integration
We deliver oracle data cryptographically verified within your ZK-rollup's proof system. This eliminates trust assumptions, reduces on-chain verification costs, and ensures data integrity is proven, not just asserted.

On-Chain Verification
02
Sub-Second Finality for L2s
Architected for rollup sequencers. Our data delivery aligns with your block production cycles, providing price feeds and randomness with latencies under 500ms to prevent missed blocks and stale data.

Custom Data Feeds & Logic
Go beyond standard price feeds. We build custom computation oracles for your application's specific needs—from TWAPs and volatility indices to cross-chain state proofs—all verifiable within your ZKVM.

Cost-Optimized for Scale
Our ZK-native design minimizes L1 settlement costs. By batching proofs and leveraging efficient verification, we reduce the operational overhead of oracle data by over 90% compared to L1 oracle bridges.

Security-First Architecture
Built with the same rigor as your core protocol. Our oracle nodes and proof circuits undergo formal verification and audits (e.g., by Trail of Bits) to ensure no single point of failure compromises your rollup's security.

Technical Architecture Comparison
Generic Oracle vs. ZK-Optimized Oracle
Why standard oracle designs fail to meet the performance and cost requirements of ZK-rollup applications.
| Architecture Factor | Generic Oracle (e.g., Chainlink) | Chainscore ZK-Optimized Oracle |
|---|---|---|
Data Delivery Latency | On-chain confirmation (2-5 blocks) | Direct L2 state proof (< 1 block) |
Transaction Cost per Update | High (L1 gas + premium) | ~90% lower (L2 gas only) |
ZK-Circuit Integration | None - external data feed | Native - data encoded as proof inputs |
Settlement Finality | Depends on L1 finality (~12 min) | Matches L2 finality (< 2 sec) |
Data Freshness for dApps | Minutes to hours | Sub-second to seconds |
Throughput (Updates/sec) | 10-100 | 1,000+ |
Custom Data Logic | Limited to pre-built adapters | Fully programmable circuits |
Development Overhead | High (oracle management logic) | Low (direct state binding) |
Typical Implementation Time | 8-12 weeks | 2-4 weeks |
Security Model | Trusted node operators | Cryptographic + economic security |

ZK-Rollup Oracle Development FAQ
Answers to the most common questions from CTOs and technical founders evaluating ZK-Rollup oracle solutions.
From specification to mainnet deployment, a standard ZK-Rollup oracle integration takes 3-6 weeks. This includes 1 week for architecture design, 2-3 weeks for core development and testing, and 1-2 weeks for security audits and deployment. Complex multi-chain or custom data feed requirements can extend this timeline, which we scope and quote upfront.
