# Blockchain and web3 consulting: what a consultancy does and when you need one

**A blockchain consultancy answers a question that comes before any code: whether your use case actually needs a blockchain, which legal framework it falls under and what architecture sustains it.** Development comes later. Most projects that fail do not fail because of the technology: they fail because someone started building before classifying the asset, choosing the chain or understanding the applicable regulatory regime.

## What a blockchain consultancy actually does

Serious work starts with feasibility: what problem is being solved, whether a distributed ledger adds anything over a conventional database, and what it costs to operate. From there, a professional [blockchain consulting](/en/servicios/consultoria-blockchain) engagement covers five fronts:

**Regulatory classification.** In Europe the first decision is legal, not technical: if the token is a financial instrument, MiFID II and Spanish Law 6/2023 apply; if it is a crypto-asset, MiCA does. Getting this wrong invalidates everything else. You can run a first check in one minute with our [MiCA or MiFID II classifier](/en/clasificador-mica-mifid).

**Architecture and chain selection.** Public, permissioned or hybrid; layer 1 or layer 2; and the right token standard: ERC-20 for simple fungibles, ERC-3643 when securities-grade transfer restrictions are needed, ERC-721 for unique assets. Each choice conditions costs, custody and compliance for years.

**Structuring and tokenomics.** What right the token represents, which vehicle issues it and how value flows. In [asset tokenization](/en/servicios/tokenizacion-activos) projects, this phase decides whether the operation is viable before a euro goes into product.

**Development and audit.** Smart contracts manage other peoples money and do not admit patch-it-later: serious [blockchain development](/en/servicios/desarrollo-blockchain) includes testing, external review and a contingency plan.

**Go-to-market.** Onboarding users who do not know what a wallet is, KYC/AML where it applies, and real adoption metrics rather than vanity numbers.

## Web3 consulting and blockchain consulting: the difference

**Web3 consulting** covers more surface than the infrastructure: it reaches into product and community — wallets and digital identity, NFTs with utility, DAOs and incentive systems, integration with your existing stack. Blockchain consulting is the foundation (ledger, contracts, custody); web3 consulting adds the experience and business-model layer. A regulated tokenization project usually needs both, ideally from the same team: product decisions that ignore the regulatory layer are expensive to undo.

## When you need a consultancy (and when you do not)

Clear signals that you do: you want to **tokenize a real asset** (real estate, debt, shares) and the legal vehicle is unclear; you are going to **issue a security token** and need an ERIR, a prospectus or its exemption; your product touches **custody or payments** and you do not know whether you need a licence; or you have a half-built development that will not pass an audit.

When you do not: if your case is solved with a database and electronic signatures, a good consultancy will tell you so in the first session — and that answer is also worth money, because it saves you an entire project. Distrust anyone who never rules blockchain out.

## How to choose

Four criteria separate substance from noise: **verifiable real projects** (with names and links, not generic logos); **an in-house development team**, because consulting without the capacity to build ends in a report nobody executes; **local regulatory knowledge** (CNMV, the ERIR figure, the sandbox), not just whitepapers; and the willingness to say this does not need a blockchain. We expand the list in [how to choose a blockchain development company](/en/mejores-empresas/como-elegir-empresa-desarrollo-blockchain).

## How we do it at Unknown Gravity

We always start with a short blueprint that validates the use case, the legal framework and the architecture before writing a line of code; only then comes development. We work on regulated projects in Spain from Malaga, with the CNMV and the ERIR figure as home ground.
