overview
CORE SERVICE

Blockchain Development

End-to-end blockchain application development for FinTechs and Web3 startups.

We build production-ready decentralized applications from concept to mainnet. Our full-stack expertise covers smart contract development on EVM/Solana, secure backend infrastructure, and responsive frontends. Deliver a market-ready MVP in 4-6 weeks.

We architect for scale, security, and user experience from day one.

  • Smart Contracts: Custom Solidity/Rust development with OpenZeppelin standards and multi-sig deployment.
  • Full-Stack DApps: Integrated frontends (React/Next.js) with ethers.js/wagmi and Node.js backends.
  • Protocol Integration: Seamless connections to Chainlink oracles, The Graph for indexing, and major DeFi primitives.
  • Security First: All code undergoes internal review + third-party audit preparation.

Core Oracle Architecture & Capabilities

Our reputation oracles are built on a battle-tested, multi-layered architecture designed for high-throughput, secure, and verifiable data feeds. We deliver the infrastructure your application can depend on.

01

Decentralized Data Aggregation

We source reputation signals from multiple on-chain and off-chain sources (e.g., transaction history, governance participation, social attestations) to create a robust, tamper-resistant score. Mitigates single-point-of-failure risks inherent in centralized oracles.

Aggregation
02

Cryptographic Attestation & Proofs

Every reputation score update is cryptographically signed and can be verified on-chain. We implement Zero-Knowledge Proofs (ZKPs) where applicable to enable private reputation verification, allowing users to prove traits without revealing underlying data.

High-Availability Node Infrastructure

Our oracle network runs on geographically distributed, auto-scaling node infrastructure with 99.9% uptime SLAs. Built-in node rotation and slashing mechanisms ensure liveness and penalize malicious behavior.

Gas-Optimized On-Chain Integration

Smart contracts are designed for minimal gas consumption during oracle updates and queries. We provide audited Solidity/Vyper interfaces for seamless integration with your dApp's existing logic, supporting major EVM chains and L2s.
