The team

Protocol Guardian is built and led by founder Rivaldo Janneh — threat model, agent runtime, on-chain Guardian contract, mempool ingestion + alert pipeline, and dashboard.

A solo founder operation. One person making every architectural call, writing every line, owning every incident. The benefit: complete coherence across the stack — from the heuristics that classify a tx in the mempool to the Solidity that calls pause() on chain to the dashboard pixel that confirms the protocol is safe.

One mission Catch malicious mempool transactions and pause vulnerable contracts in real time.
Founder & lead dev

Rivaldo Janneh

Solo founder · Full-stack agentic systems · ETHGlobal Open Agents 2026

Rivaldo built Protocol Guardian as a one-person stack — he writes the Solidity, designs the threat heuristics, runs the AI agent loop, owns the on-chain registry, ships the alert pipeline, and ships the dashboard.

His background sits at the intersection of agentic AI and on-chain security: he's the kind of engineer who reads every exploit post-mortem the day it drops and asks "could a better-positioned agent have caught this in the mempool?" Protocol Guardian is the answer.

When he's not shipping, he's reading exploit post-mortems and tightening the heuristics. The roadmap is set by what he sees in the wild, not what's on a slide.

Stack ownership

Five layers. One owner.

Protocol Guardian's architecture isn't farmed out across teams. Rivaldo writes and maintains every component end-to-end.

01

Threat model & heuristics engine

Pattern-screening for flash loans, reentrancy, oracle manipulation, TVL drains, access-control violations, and governance attacks.

02

AI agent runtime

The Claude-based reasoning loop that classifies threats, scores confidence, and decides whether to pause.

03

On-chain Guardian contract & registry

GuardianController.sol plus the protocol registry that tracks every contract under monitoring on Sepolia.

04

Mempool ingestion & alert pipeline

WebSocket ingestion, transaction routing, the heuristics-to-agent escalation queue, and the post-incident report generator.

05

Dashboard & marketing site

The live operator dashboard at protocol-guardian.vercel.app plus this public surface — design, copy, code.
