When every word has to protect the experience

In a digital wallet app, language isn’t just communication — it’s security. An ambiguous term in a transaction flow, a confusing instruction on the receive screen, an imprecise legal notice: any slip can cause real errors with financial consequences for the person using it.

It was with that weight in mind that I worked on the review and localization of VVWallet, a Web3 wallet focused on the Latin American market.

Building language that earns trust

I translated and adapted the site, the app, and the legal documents into Portuguese — including the Terms of Use and Privacy Policy. More than translating, the challenge was striking the right balance between technical precision and clarity: crypto terms that had to be understandable for someone just arriving in that world, without losing the exactness that people already in it expect.

I proofread all three versions of the product — Portuguese, English, and Spanish — driving terminology consistency across the languages and making sure the experience felt coherent no matter which one someone chose.

Beyond the text: a UX lens

My role went beyond writing. I ran quality tests on the app, evaluating the flows against Nielsen’s heuristics — spotting where navigation could be more intuitive, where the copy raised doubt, and where a small change in wording cut friction and built confidence.

What this project taught me

Clarity isn’t an edge. It’s a responsibility.

Working on VVWallet reminded me that in a digital wallet, language isn’t just communication — it’s security.
