# Introduction

> Add proof to anything, on-chain without writing a line of code

## Whenever you need to prove something onchain — *identity, action, ownership, or permission* — you don't need to write a new smart contract or spin up a ZK system.

Attest provides a proof infrastructure to build anything from **network states, DAOs, DePIN, and RWA**. With our **Unified Trust Framework,** developers on Stellar can integrate reputation and trust mechanisms in their dApps.

## Add proof to anything, on-chain without writing a line of code.

AttestProtocol is a Soroban-based framework that lets you attach attestations to any wallet, asset, or event. Whether that's *proof of identity, contribution, credential, or ownership.* No contracts, no infrastructure, no ZK black magic required.

<Tip>
  Think of it like SSL for blockchains — a lightweight trust signal you can apply anywhere.
</Tip>

## An Open Standard for Trust

Using our **Attestation Service** you get an open standard for verifying *statements, transactions, and authorities* — identity proofs **on the blockchain**.

Our **Soroban framework** enhances the reliability of digital interactions on the Stellar Network with a composable blockchain-based **Attestation Service.**

## Who is this for?

### Attestation Issuers

KYC providers, event organizers, DAOs, and certification bodies who want to:

* Issue verifiable credentials on-chain
* Enable other apps to verify your attestations
* Build reputation without siloed databases

### Verifiers

Applications that need to:

* Check if a user has valid KYC from any trusted provider
* Gate access based on credentials without vendor lock-in
* Query attestations from multiple issuers in one place

### Developers

Teams building:

* Reputation systems using aggregated attestation data
* Credential verification into existing dApps
* Multi-source identity checks
