CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built for production by Web3-native engineers.
- Custom Logic: Tailored
Solidity/Rustcontracts for unique tokenomics, governance, and business rules. - Security Audits: Development includes formal verification and peer review, with optional integration of third-party audits from firms like OpenZeppelin or CertiK.
- Gas Optimization: Every line of code is optimized for execution cost, reducing user transaction fees by up to 40%.
- Full Lifecycle: From initial spec to deployment on
EVM/Solana/Starknetand ongoing maintenance.
Deliver a production-ready, audited smart contract system in 3-6 weeks, not months. We handle the complexity so you can focus on your product.

END-TO-END ENCRYPTION
Core Features We Implement
We build secure, compliant messaging platforms with zero-trust architecture, ensuring your users' conversations remain private and your application meets regulatory standards.
04
On-Chain Message Integrity & Notarization
Anchor message hashes to public blockchains (Ethereum, Solana) for immutable, timestamped proof of communication. Provides non-repudiation and audit trails without storing message content.
05
Ephemeral & Self-Destructing Messages
Build configurable message expiration with client-side enforcement. Messages are automatically deleted from all devices after a set time, with proofs of deletion verifiable on-chain.

TRANSPARENT & SECURE
Our Development Process
A proven, end-to-end methodology for building encrypted messaging platforms that prioritize user privacy, regulatory compliance, and seamless user experience from day one.
01
Architecture & Protocol Design
We architect your platform using battle-tested protocols like Signal Protocol, MLS, and zk-SNARKs for end-to-end encryption. Our designs ensure forward secrecy, deniability, and resistance to quantum attacks.
