Martin Ndeto, Blockchain Engineer
Software Engineer with a computer science background. I specialize in decentralized systems and have extensive experience building on blockchains. I build smart contracts, design protocols, develop tooling, and ship AI-enabled products that operate reliably in production across onchain and hybrid systems.
What this site is
Purpose
A working archive of systems, experiments, implementation notes, and linked artifacts across blockchain, backend, AI, infrastructure, and distributed software.
Work History
See LinkedIn for that.
What I Do
Research
I work on specifications across the ethereum ecosystem spanning across interoperability, identity, and agent systems, then publish practical implementations.
Engineering
I design and build systems that turn these specifications into working code, spanning onchain contracts, offchain components, SDKs, and end-to-end demos.
Recent Work
My focus has been Agentic Web infrastructure: building systems that treat AI agents as first-class actors on the web. Beav3r is exploring authorization and execution across blockchain and traditional systems for AI agents.
Beav3r
Beav3r is an authorization and execution protocol and control plane for AI agents across both blockchain and traditional systems. The project combines distributed systems, cryptography, identity, authorization, and AI infrastructure to address a core challenge of the agentic web: enabling autonomous agents to operate within real world systems while remaining accountable, auditable, and controllable.
Through Beav3r, I have designed and built systems for agent identity, delegation, policy enforcement, human oversight, and verifiable execution, drawing on both crypto native primitives and established computing concepts.
Past Focus
Interoperable Addresses and Names
Cross-chain identity and discovery using ERC-7930 and ERC-7828 with ENS-backed chain registry resolution. This work is informed by hands-on development and personal contribution to the Ethereum Chain Registry, including core resolver logic and registry tooling.
txpool-viz: Execution and Mempool Tooling
A tool to visualize and compare transaction pools across different Ethereum execution clients. This helps debug transaction propagation issues, analyze mempool behaviors during attacks, and understand differences in transaction acceptance policies between clients.
x402 Payments and Identity
I designed and implemented ENS-based payTo support for the x402 protocol, enabling
identity-anchored payment routing for agents. This work connects decentralized identity with
request/settle payment flows, allowing agents to resolve payment destinations via ENS rather
than hardcoded addresses.
In addition to the core payTo mechanism, I implemented ENS-aware identity metadata
extensions that allow agents to attach, resolve, and interpret identity context during x402
message exchange.
Trustless Agents x ENS
When a trustless agent sets an ENS name in its registry, ENSIP-25 provides the verification path so ownership claims can be trusted across AI agent registries.
I implemented it in the agent0 SDKs to make ownership checks portable and reliable for agent-to-agent interaction.
Resolver-Based Discovery of Agent Delegation Credentials
In the agentic web, agents are first class actors that must discover and verify delegated authority. This work implements the Agent Delegations ERC draft, and demonstrates how delegation credentials can be trustlessly resolved from an ENS identity using a custom credential resolver plus ECS hook routing.

Engagement
I plug in as a systems engineer and builder, turning ideas into working software through hands-on implementation.
I combine architecture, end-to-end engineering, and product oversight, taking production systems from design to delivery in fast-moving environments.
