We explore what could exist. ## Areas of focus ### 01. Artificial Intelligence & Autonomous Agents (Intelligence Systems) *Applied AI, autonomous agents and tool-driven systems.* We build AI systems that can interpret context, plan actions and carry out multi-step operations. We integrate models, tools, APIs and infrastructure to turn intelligent agents into operational components of real systems. Our research goes beyond text generation. We explore agents with execution capabilities, controlled access to resources, authorization policies and interaction with financial services and digital protocols. **What we do:** - **Agents that execute.** Agents that use tools, query services, coordinate tasks and run workflows within defined permissions and limits. - **Agentic Commerce & x402.** Architectures that let agents discover services, negotiate operations and initiate programmatic payments through protocols such as x402, UCP (Universal Commerce Protocol) and ACP (Agentic Commerce Protocol). - **Orchestration and control.** Task execution with access policies, delegated sessions, operational limits and traceability of every action taken. **Applications:** AI agents connected to APIs and tools; Autonomous commerce between agents and services; Automation with granular authorization; Agents with transaction capabilities.

Blockchain, Privacy & Protocols (Privacy Engineering) *Blockchain, ZK proofs, smart accounts and private transactions.* We design blockchain architectures that combine asset programmability, account abstraction, cryptographic privacy and control over how financial information is exposed. We work with technologies such as stealth addresses, shielded pools, zero-knowledge proofs and interoperability mechanisms with the Ethereum ecosystem. The focus is on systems in which identity, authorization and asset movement can be handled with different levels of transparency, without giving up the verifiability each application requires. Privacy does not mean the absence of rules. It means designing which information is revealed, to whom and under what conditions. **What we do:** - **Stealth Addresses & Identity Privacy.** Stealth address architectures that reduce the public link between a user’s identity and the addresses used to receive assets. - **Shielded Pools & Zero-Knowledge Proofs.** Exploration of shielded transactions, cryptographic proofs and selective disclosure mechanisms to reconcile confidentiality and verifiability. - **Kohaku & Ethereum Privacy.** Integration and experimentation with the Kohaku toolkit and the Ethereum ecosystem’s privacy primitives, evaluating composition, compatibility and protection models. - **Smart Accounts & Cryptography.** Programmable wallets, Account Abstraction, delegated permissions and cryptographic authorization mechanisms for digital operations. **Applications:** Wallets with privacy features; Programmable assets and payments; Verifiable identities and credentials; Auditing with selective disclosure.

Software Engineering & Edge Computing (Distributed Systems Engineering) *Edge computing, distributed state and programmable infrastructure.* We build distributed systems that run logic close to users, coordinate operations in low-latency environments and keep state consistent without relying on a centralized monolithic architecture. We use Cloudflare Workers, Durable Objects and distributed storage to create event-driven backends, services with persistent coordination and applications that operate globally. We combine edge computing, APIs, messaging and on-chain integration in architectures designed for real performance, availability and security needs. **What we do:** - **Edge Computing & Cloudflare Workers.** Geographically distributed business logic, low-latency APIs and scalable services without maintaining traditional servers for every component. - **Durable Objects & State Coordination.** Persistent state, entity-based coordination and synchronization mechanisms for sessions, agents, workflows and concurrent operations. - **Hybrid On-chain and Off-chain Systems.** Integration between smart contracts, wallets, APIs and edge services, splitting responsibilities between on-chain execution and external processing. - **Storage, Events & Observability.** Architectures with object storage, operational persistence, event processing and monitoring for distributed applications. **Applications:** Global backends at the edge; Orchestration of agents and sessions; APIs for wallets and protocols; Distributed systems with persistent state.

Deep Tech, Security & New Architectures (Advanced Systems & Security) *Device attestation, hardware security, confidential computing and post-quantum cryptography.* We research and develop architectures that connect digital identity, device security, cryptographic key protection and new forms of computing. Our approach covers a system’s entire chain of trust: from the device that requests an operation to the environment that executes it, from the credentials used to the keys that authorize transactions. We evaluate attestation mechanisms, execution isolation and cryptography to reduce attack surfaces and strengthen the integrity of digital operations. **What we do:** - **Device Attestation & Hardware Trust.** Attestation mechanisms that assess the authenticity and integrity of devices and applications before granting access to sensitive operations. - **HSM, Secure Element & Key Management.** Key protection architectures with hardware security modules, secure elements and separation between authorization, custody and execution of cryptographic operations. - **Post-Quantum Cryptography.** Research and evaluation of algorithms resistant to quantum computer attacks, including cryptographic migration strategies and compatibility analysis with existing systems. - **Identity, Biometrics & Authorization.** Integration of credentials, biometric authentication and authorization factors into architectures that protect access to identities, wallets and digital assets. **Applications:** Device authentication; Key and wallet protection; Digital trust infrastructure; Migration to post-quantum cryptography.

Precision engineering.** We believe real technology starts before the code. It starts with the ability to understand systems, spot opportunities and ask better questions. 1. **Question.** We analyze assumptions, identify limitations and investigate paths that have not yet been explored. 2. **Conceive.** We turn hypotheses into consistent architectures, strategies and technology models. 3. **Build.** We develop concrete, integrable solutions ready to operate in real environments. 4. **Evolve.** We continuously refine our solutions to keep pace with new demands, discoveries and opportunities. ## What sets us apart **Complexity is not a barrier. It is our territory.** METAPHI connects different technology disciplines to build solutions that are not confined to the boundaries of a single platform or approach. - **Multidisciplinary vision.** We bring AI, blockchain, software and infrastructure together into a unified technology perspective. - **Future-ready architecture.** We design systems with interoperability, security, modularity and continuous evolution in mind. - **Strategy before execution.** Every technical decision must answer a real problem and deliver measurable value. - **Innovation with purpose.** We explore new possibilities with technical rigor, responsibility and a focus on concrete applications. ## Manifesto **The conventional is only the starting point.** Progress begins when we question what everyone considers impossible, final or good enough. At METAPHI, we combine intelligence, engineering and strategic thinking to explore new technological frontiers. We investigate complex problems, challenge established models and build solutions that expand what is possible today. We don’t build technology just to keep up with change. We build it to take an active part in it. - We question what exists. - We design what is missing. - We build what comes next. ## About METAPHI **We don’t follow technological frontiers. We investigate what lies beyond them.** METAPHI Deep Tech is a technology company focused on research, engineering and the development of advanced solutions in artificial intelligence, blockchain and digital systems. Our work combines analytical thinking, technical expertise and a long-term vision to take on challenges that demand new perspectives. We operate at the intersection of emerging technologies and real needs, turning complex concepts into applicable solutions. Our ambition is to contribute to the next generation of intelligent systems, digital infrastructure and technology experiences. ### Where the name comes from Metaphi combines meta (μετά, “beyond, above”) with phi (φ), the Greek letter of the golden ratio and, in consciousness science, of the measure of integrated information. It can be read as “beyond consciousness” or “higher intelligence”. From this convergence comes our vision: to use intelligence to transcend limits, turn the unknown into concrete possibilities and anticipate the next frontiers of technological evolution. At the intersection of Artificial Intelligence, Blockchain and Deep Technology, we develop solutions that connect intelligence, computing and innovation to redefine what is possible. We explore emerging technologies and intelligent systems to build infrastructure capable of transforming businesses, markets and the very relationship between humans and technology. We don’t just follow technological evolution. We investigate what comes next. We question the conventional, anticipate transformations and turn complex challenges into strategic solutions for a smarter, more autonomous and more connected future. METAPHI represents the convergence of philosophical thought, strategic intelligence and advanced technology. A vision that does not accept the limits of the present as the frontiers of the future. > We do not limit ourselves to what exists. We explore what could exist. ## Innovation and partnerships **The next breakthrough starts with a different question.** Some problems cannot be solved with the same old ideas. METAPHI exists for those challenges. Let’s explore what hasn’t been built yet. - E-mail: deivison@metaphi.tech - Talk to METAPHI: https://metaphi.tech/en/#contato --- [Português](https://metaphi.tech/index.md) · [Español](https://metaphi.tech/es/index.md) · [Русский](https://metaphi.tech/ru/index.md)
