Core Tech for aTrustless Web3 Stack
Cryptographic proofs instead of trust: access Ethereum and EVM chains with answers you can verify in your own process—not on faith in a provider.
Our Products
Trustless blockchain access for any application. From verification to privacy to autonomous systems.

Colibri Stateless Client
Trustless Blockchain Access. With Built-in Privacy.
Colibri is a fully verifying stateless client for Ethereum and EVM-compatible chains. It enables applications to access and validate blockchain data locally using cryptographic proofs, without relying on trusted RPC providers.
Only Solution Combining All Three

vRPC
RPC Responses You Can Verify.
Blockchain data together with cryptographic proofs. Drop-in replacement for traditional RPC while removing the need to trust infrastructure providers.

Transaction Security Agent
Understand and Verify Transactions Before You Sign.
Security and privacy layer that analyzes, simulates, validates, and explains transactions before signing. Ensures users understand transaction effects based on verified state.

IoT/Embedded Framework
Blockchain Verification for Constrained Devices.
Framework for integrating trustless blockchain verification into IoT and embedded systems with limited resources and intermittent connectivity.

AI Agentic Framework
Trustless Data and Verfication for Autonomous Agents.
Framework that enables AI agents to operate on verifiable blockchain data and execute actions securely with deterministic guarantees.
Our Services
We provide end-to-end services for building and deploying trustless blockchain infrastructure. From core technology development to consulting and maintenance, we help organizations embrace decentralized technologies for real-world applications.
