Magnus Krypt / Web3 product and infrastructure engineer

Tailor-made Web3 systems built for visible proof.

I turn hard technical briefs into clear, working products across agent systems, Solana infrastructure, privacy, compliance, payments, and crypto-native interfaces.

KudiFlow autonomous commerce agent product interface

Featured build / KudiFlow / Celo

GitHub 0xNexuz

Public repos 72

Core focus Agents + infra

Flagship work / selected, not exhaustive

Three builds that carry the portfolio.

Each one answers the employer question directly: what problem was solved, what was engineered, and what proof can be inspected today.

Repository evidence / architecture and lifecycle logs

01 / Solana infrastructure TypeScript

Smart Transaction Stack

Built an AI-assisted Solana transaction pipeline that observes network state, chooses Jito tips, submits bundles, tracks commitment stages, and classifies failures.

AgentVault policy-bound autonomous treasury product interface

Live product / BOT Chain

02 / Agent infrastructure JavaScript + Solidity

AgentVault

Built policy-bound treasuries that let autonomous agents execute without taking unrestricted custody: owner limits, allowlisted actions, emergency pause, and on-chain receipts.

AnonCompliance privacy-preserving compliance product interface

Live product / Stellar testnet

03 / Privacy infrastructure Groth16 + Soroban

AnonCompliance

Built a privacy-preserving compliance gate where users prove policy eligibility without exposing identity data, with nullifier protection and real Stellar testnet actions.

Builder signature

Autonomy with visible policy, evidence, and control.

Across chains and product categories, the same engineering thesis keeps appearing: agents should move quickly, but every consequential action should be bounded and inspectable.

01 Policy before execution

PolicyMesh, AgentVault, KudiFlow

02 Receipts after action

Signed decisions, explorer links, lifecycle logs, audit exports

03 Evidence over claims

Testnet deployments, live demos, deterministic tests, public source

Job category frames

Best builds, grouped by the roles they prove.

A recruiter, founder, or hackathon team should not have to decode the repo list. These frames map the strongest builds to the exact kind of work Magnus can own.

KudiFlow turns policy into purchasing power.

KudiFlow turns a merchant restocking brief into policy-checked procurement on Celo, buys live x402 market signals, and exposes tagged USDC settlement receipts.

Case files

Recent releases, stated in employer language.

No mystery labels: each case names the user problem, the system built to solve it, and the technical evidence behind the claim.

Commerce agents / Celo

KudiFlow

Built an autonomous procurement agent for informal merchants that buys x402 signals, applies deterministic spend policy, and settles approved suppliers in tagged USDC.

Agent safety / developer tools

PolicyMesh

Built a deterministic checkpoint between AI agents and consequential actions, with allow, review, and block decisions across payments, files, and APIs.

Structured action proposals
Human approval and emergency stop
Replay protection and signed records

Market agents / data systems

EdgeArena

Built an agent-vs-agent market arena around real TxLINE fixtures, deterministic strategy logic, persistent receipts, backend-proxied streams, and proof payload checks.
