Web3 Marketing: Onchain Data, Communities and Campaigns for Brands
For marketers, a blockchain is mostly a new data source and a new way to grant access. Public transaction data shows what wallets hold and do, tokens can unlock offers or content, and communities form around both. This hub covers the practical side: what you can measure, what you should not collect and how to report results.

What onchain data can and cannot tell you
| You can see | You cannot see |
|---|---|
| Which tokens a wallet holds and when they were acquired | Who the person behind the wallet is, unless they tell you |
| How active a wallet is across applications | Offline behavior, income or demographics |
| Holder overlap between communities | Whether several wallets belong to one person |
Campaign formats
- Token-gated offers or content for holders of a pass or collectible.
- Allowlists for early access that reward existing customers.
- Achievement tokens for attending events or completing actions.
Privacy and compliance
Linking a wallet to an email address or a customer profile can make it personal data. Treat that link like any other customer data: ask for consent, minimize what you store and explain it in your privacy notice.
Measuring results
- Report reach, conversion and retention in the same way as other channels.
- Separate first-time crypto users from experienced holders; their behavior differs.
- Count total cost: vendors, gas fees, community management and support.
