A certificate proves something happened. On its own it cannot prove it happened to you, or that the file in front of somebody is the one the school issued. Your Wallet is where those documents live, and where anybody you show them to can check them without taking your word for it.
A first job is hard to get when everything you have done sits in a PDF a recruiter has to take on trust. Your Wallet is one link, read in a minute, with the school's own proof sitting on the line it belongs to.
Every role, every course and every skill on your page can carry a confirmation from the person or the school who knows it is true. You write the line. Somebody else stands behind it.
Diplomas, licences, certificates and the receipt you will need in four years, kept in one place and still there long after the email they arrived in is gone.
Your page opens with who you are, then your roles and your education, the documents behind them, your skills, and the references that back them up. You decide what is public and what stays in your Wallet, line by line. It is one link, and new documents appear on it on their own.
A document issued through TRUE is secured the moment it is issued, so anyone can check it against the record and see that nothing in it has moved. A document you upload yourself is yours to add, and your page says so. A reference is the third kind: a person or a school confirming a line you wrote. Wallet keeps the three apart, because a page that treats them as one is worth nothing to whoever is reading it.
It is free, it stays yours, and you can start with the documents you already have in your inbox.
