Private Event Logging Service

Design and implement systems that emit encrypted event logs from stealth contracts, enabling authorized audit trails without exposing sensitive on-chain data to the public.

overview
CORE ENGINEERING

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process ensures security-first design, gas optimization, and audit readiness from day one.

  • Token Standards: ERC-20, ERC-721, ERC-1155, SPL for fungible and NFT assets.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking contracts.
  • Enterprise Logic: Multi-signature wallets, vesting schedules, and custom governance modules.
  • Security Foundation: Built with OpenZeppelin libraries and formal verification patterns.

Deliver a fully audited, mainnet-ready contract suite in 4-6 weeks, with documented test coverage exceeding 95%.

Core Capabilities of Our Private Event Logging System

A purpose-built, zero-trust logging layer for Web3 applications, delivering tamper-proof audit trails, real-time insights, and regulatory compliance without compromising on-chain privacy.

01

Zero-Knowledge Data Integrity

Generate cryptographic proofs (ZK-SNARKs/STARKs) that verify event data authenticity and sequence without exposing sensitive payloads. Enables trustless verification for auditors and partners.

Frequently Asked Questions

Get clear answers on how our enterprise-grade private event logging service works, its security, and integration process.

Private event logging is a service that captures and stores blockchain transaction events (like token transfers, contract calls) in a secure, off-chain database with controlled access. You need it to enable internal analytics, compliance reporting, and customer dashboards without exposing sensitive business logic or user data on the public ledger. It decouples data availability from on-chain constraints.
