Blockchain · Service Blockchain consulting and architecture

Independent advice before you build: whether a blockchain is the right tool, which chain, how to handle keys, upgrades and audits, and what it will cost.

In short

Blockchain consulting answers the questions that are expensive to get wrong once a build has started: whether the problem needs a blockchain at all, which chain fits, what lives on-chain and what does not, who holds the keys, and how the system will be upgraded and audited. We give a written recommendation you can act on with any team, including one that is not ours.

Blockchain consulting and architecture — how Vayro delivers it: Listen, then Test the options, then Write it down, then Optionally build. Includes whether to use a chain at all, chain and standards selection, architecture document, key and role design.
When you need it

Signs this is the right service

  • You have a product idea involving tokens or on-chain assets and need to know whether the architecture holds up.
  • You are choosing between chains, or between a public chain, a rollup of your own and a conventional database.
  • A vendor has proposed a design and you want an independent read before signing.
  • An existing protocol needs an upgrade, a migration or an audit, and the plan is not clear.
What's included

What you get

Whether to use a chain at all

What a blockchain gives this product that a database does not — and a recommendation against one where that is the honest answer.

Chain and standards selection

The candidate networks and token standards compared against your users, assets, costs and partners.

Architecture document

What is on-chain, what is off-chain, how the two stay consistent, and how the contracts can be upgraded or paused.

Key and role design

Who can do what: admin roles, multisig thresholds, timelocks and a recovery plan, written before any deployment.

Audit and cost plan

What needs an independent audit, when to book it, and estimates for build, audit and running costs.

How we deliver it

The process

  1. 01

    Listen

    The product, the users, the assets involved, and the constraints your lawyers and partners have set.

  2. 02

    Test the options

    Candidate designs compared on cost, security and complexity, with a small prototype where a claim needs checking.

  3. 03

    Write it down

    An architecture document and a risk list in plain language, yours to keep.

  4. 04

    Optionally build

    If you want us to build it we can, and the document works equally well with another team.

Questions

Blockchain consulting: common questions

Will you tell us if we do not need a blockchain?

Yes. Many products are better served by a conventional database with good audit logs, and saying so early is where the largest saving is.

Do you give legal or regulatory advice?

No. We work with your legal counsel and design systems that enforce the rules they define.

Which chains do you cover?

Ethereum and EVM-compatible networks, including the main layer-2 rollups, and Rust-based chains such as Solana where a project needs them.

Can we take the recommendation to another developer?

Yes. The document is written to be built from by any competent team.

New projects

A paragraph about the problem is enough to start. We reply within two working days, usually with questions rather than a quote.
