Blockchain and x402 consulting

I help founders and product teams assess whether blockchain fits their problem and design the application around it. For x402 projects, we work through the paid API or resource, payment verification, access, and failure handling.

Where I can help

Assess the fit

Identify the trust problem, participants, ownership needs, and alternatives before committing to a blockchain.

Design the transaction flow

Map wallets, signing permissions, contract interfaces, transaction states, and recovery after failures.

Plan an x402 integration

Define the paid resource, price, payment verification, access rules, and how repeated or failed requests should behave.

Scope a prototype

Choose a small integration and the checks needed to learn whether it is ready for the next stage.

What you can take away

An agreed scope can produce a payment-flow diagram, integration requirements, or a small prototype. For example, we could map what should happen when a paid API request succeeds, is retried, or fails before the response reaches the buyer.

See pricing or read how we work together. We agree on the output before paid work starts.

Agreeing the scope

An advisory or implementation scope can cover your application and its payment flow. Formal smart-contract audits, investment advice, tax advice, and regulatory opinions are separate. Network fees and third-party services need an agreed budget.

My Waterloo doctoral research covered decentralized oracle networks and AI-assisted smart-contract repair. CountChain and GasGauge are examples of that work. More about my background.

Three ways to start

Initial session

Free / 30 minutes

A conversation about your situation, the decision you need to make, and whether I can help.

Share a brief and book

Hourly consulting

$200 USD / hour

Focused advice, a technical discussion, or a review. One-hour minimum, with preparation and limits agreed in advance.

Discuss hourly work

Custom work

Let's talk

For an assessment, implementation, or ongoing support that needs its own scope and price.

Tell me about the project

Share a short brief first, then choose a time for a free 30-minute initial meeting. Paid work starts only after we agree the scope and price.

Let's talk about your project.

Tell me about the resource, the buyer, and the payment or trust decision you need to make.
