In today’s internet, we’re often asked to share personal information our age, location, ID numbers just to access services or pass simple checks. What if you could prove what’s needed without showing anything else?

That’s what Mina Attestations allows. Built on Mina Protocol, a blockchain known for its small size and focus on privacy, Mina Attestations is a tool that helps users prove facts about themselves without revealing too much.

What Is Mina Attestations?

Mina Attestations is a JavaScript library that helps developers add private identity checks to their apps. It was previously called the "Private Credentials API" and has now been completed by the zkSecurity team. This tool lets users prove things like:

  • I’m over 18

  • I’m not from a restricted country

  • I passed a KYC check

...without showing their exact age, country, or ID.

It uses a type of math called zero-knowledge proofs (ZKPs). These proofs let you say, “I meet this rule” and others can trust you without knowing your personal data.

Security First: Audit + Bug Bounty

Before launch, Mina Attestations was audited by Hacken, a well-known blockchain security company. They checked the code, the cryptography, and its connection to Mina wallets like Pallad.

All the important security issues were fixed, and a 1-month bug bounty is now live on Hackenproof. This means the tool is safe for developers to use.

How It Works

There are three roles in the Mina Attestations system:

  • Issuer: Gives the credential (like a company saying “This user passed KYC”)

  • User: Receives the credential and can prove parts of it

  • Verifier: Asks to see only what’s needed

Let’s say a crypto exchange wants to check if you are not from a restricted country. Instead of asking for your passport, they can ask for a proof that only says “Yes, I’m allowed.” You stay in control of your data.

Supported Credential Types

There are two main types:

  • Native Credentials: Signed directly on Mina — very efficient

  • Imported Credentials: From other systems, using ZK proofs. These include:

  1. ECDSA credentials (for Ethereum-like wallets)

  2. ZkPass credentials (for checking age, nationality, etc.)

This makes it possible to bring your existing Web2 or Web3 identity into Mina, without giving away extra details.

Works With Wallets

Mina Attestations already works with Pallad Wallet and is being tested with Auro Wallet. This means users will be able to share proofs from inside their wallet, just like sending a transaction.

Why It Matters

With more services asking for identity checks, privacy becomes a challenge. Many apps don’t need to know everything just one fact. Mina Attestations helps solve this. It brings a better way to handle identity in Web3: one where users stay in control.

Thanks to Mina’s small blockchain size and support for off-chain proof creation, tools like this are now easier to use. Developers can add privacy features without needing complex backend systems or heavy infrastructure.

Mina’s Privacy Focus in Action

Mina has always been built with privacy in mind. Its blockchain stays small in size, and users can create and verify proofs on their own devices. Anyone can run a full node without needing powerful hardware.

Now, with Mina Attestations, this vision becomes more real. It’s not just an idea anymore it’s something developers and users can actually use today to protect personal data in a smart and simple way.

Whether you're building identity apps, wallet integrations, or just want more control over your data, Mina Attestations gives you a clean and privacy-focused way to do it.
